Cover flow Display in iPhone application

Hi, How can I use the cover flow display in my application? Which class should I extend from for that?

There is no public class/api for Coverflow so you need to write your own.

Cover Flow Display Problem

Has anyone experienced the situation where in cover flow display the album cover will appear when not the primary display (it's one to the left or right and appears 'sideways') but when you place it in the primary display position (the one you're focused on) that area is just black? This is only happening on a few albums but not others. If anyone has a solution to this I'd really appreciate it. I'm very computer savvy, and have tried everything I can think of but can't fix it.

After hours of frustrating experimentation, my partner appears to have found a workaround for this problem. If you have cover art not showing up at all, or showing up in the Cover Flow, but not when you turn your iPod Touch back vertically, this is what to do. If you view the info on a single file in iTunes, you'll notice the cover art sits in the middle of the screen in the Artwork view. What you need to do is create a blank 200x200 72 resolution image file (I don't think these paramaters must be exactly as noted, you just need a square, blank image file). Then add this blank image as a second image to the album that won't display its cover art. Afterward you should have the original artwork on the left half of the display and the blank part on the right. It won't work to just use the slider to get the original file to the left by sliding the slider one place to the left, because once you exit it just puts the picture back in the middle again. You have to add a blank image file. (In fact, the second image file doesn't even have to be blank, if you just want to use another album image file you have.) Once you have the artwork you want displayed fixed to the left half, everything works fine.

Cover Flow displays generic icon only for small JPEG files

I recently used the excellent CocoThumbX to strip off all the Adobe preview icons from my Photoshop-created images (a mixture of JPEG, TIFF, and PSD files). That neatly solved the low-res "fuzzy" Cover Flow thumbnail problem lots of users have complained about.
However, now I have a problem that I haven't seen addressed elsewhere. Lots of my JPEG files still appear as generic JPEG icons in Cover Flow. They are all Adobe Photoshop JPEG files, and they are all no larger than 150KB in size. There's nothing wrong with the files as Quick Look displays them without a hitch, and I can open them in Photoshop no problem.
Any idea how to get Cover Flow to render their thumbnails properly?
Resaving them from Photoshop fixes the problem, but I have thousands of such images and don't want to resave all of them even with a batch action if there's some other simple way of fixing this.

I have the same problem except with ALL jpegs, not just small ones. Other file types (pdfs, eg) preview just fine in cover flow, and I am able to open all the jpgs by themselves in any program, they just don't render in cover flow.
I think this happened in conjunction with the upgrade to 10.5.1.
Any help would be most appreciated!

Cover flow displays the same two pieces of artwork for all videos.

I've been adding a collection of tv series I have on DVD to iTunes 9.1.1, it all worked fine initially, I opened each video up of a series of tv programs and used the "Set Poster Frame" option to capture a frame of the program to use as the artwork for that program.
I normally have the programs sorted by what tv program they belong to, so Cover flow only displays the first episode of a series' artwork. I'm not sure why though but something I did yesterday appears to have caused cover flow to blow a fuse.
If I chose to sort by name before, cover flow would display all the artwork for each episode, and it showed all the different artworks correctly. Now though after some fiddling I did which I cannot seem to recount my steps back to, it only displays the same two pieces of artwork from two particular episodes for all the videos when it is sorted via name:
http://img257.imageshack.us/img257/3052/tvprogcoverflow.png
I've tried removing all the artwork, but there doesn't seem to be an option to delete the poster frame and the poster frame artwork doesn't show up under the artwork tab for the individual videos so I can't delete anything from there. If I select all the videos and then right click and get info, then select the artwork check box and click OK it seemingly deletes all the artwork... Then replaces it again with the exact same artwork!
Although cover flow shows each video has having the same artwork if I Get Info each video it clearly shows it having the correct artwork so why cover flow is messing around like this I don't know.
I've tried deleting the album artwork cache in the itunes folder, didn't work. I even tried deleting my entire itunes folder which I have separate from my library and the hidden prefs file in my actual library, but that didn't work either.
Interestingly enough, if I re-add all the videos they automatically get listed as films and go under the film tab. When looking at them under their cover flow correctly shows every episode with the right artwork:
http://img200.imageshack.us/img200/8234/filmcoverflow.png
As soon as I change the Get Info options tab from Film to TV program either for one video or all of them, then cover flow screws up again.
Any idea how to fix this annoyance?

The weird thing is, it worked before. I encoded all the videos previously and had them all listed and didn't encounter this problem, but I noticed I'd forgotten to decomb/detelecine the videos so I deleted everything and re-encoded it all. AFter filling the tags out and setting poster frames again I was thinking of making life easier by just pasting the same artwork for every episode, so I did, but didn't like the results so I deleted it again (I selected every video, used Get Info and pasted the artwork that way).
I think it was after this that the problem started to occur. In any case I've been through every episode and made sure the name, series, episode and episode id fields are all filled in with incremental values and they are. I even made sure the Sort Name field was filled in on every video. But this didn't work either.
So, thinking another restart was needed I deleted every video again. Re-encoded them all, again. Set the tags for every video and poster frame again. Finished it all off nicely, checked cover flow and was highly annoyed to find it was STILL showing the same two pieces of art work for every video as shown in that image I posted.
Ultimately, I wouldn't care so much that cover flow is screwing up like this as I always intended to sort by program anyway so it would only ever display one piece of artwork for an entire series of videos, however where-as when it was working it picked the artwork for the first episode of a series to display, its instead picking one of the latter episodes. I can't seem to find any way of choosing what artwork I want displayed.

Cover Flow - Display adapter drivers

Hi there, I know a lot of people have posted about this problem but I am wondering if anyone can help me out.
I am unable to use cover flow on my pc. I have made sure I have the latest itunes and quicktime. As far as drivers go this is my sticking point. I don't know if there are newer drivers for the display adapters. I have been to the manufacturers website (S3 Graphics) but it seems that it has been discontinued with no further support (I am not sure I am looking up the right drivers anyhow). The display adapter I have is S3 Graphics ProSavageDDR. The driver date is from 2003 (version 6.0.0.0).
Can any techie person help me out here. I would love to get cover flow working on this pc.
Thanks in advance

'Cover flow 'display splits albums

When I view my albums in 'grid' format all are shown individually & correctly, but when I switch to 'cover flow' the albums split showing many covers of the same album each carrying a track from that album.
Is this a 'bug' or am I doing something wrong?

Thanks cynic and DucMike, but that wouldn't explain why the display in 'cover flow & 'grid' are different in terms of slitting albums.
BUT!! Cynic, I think you may have hit on something here and a confession I have to make.
I tag all my albums as follows:- The artist in 'Album' tag and the name of the track or album in the tag 'Album artist'!
Why? Because this way I get the name of the artist displayed above the track/ album which is the way I want to view them. It wuld seem though that produces the splitting effect I refer to.
For example The Beatles Abbey Road. In grid format, one album cover displayed. In cover flow, about a dozen covers scattered around.
I will try to re-tag this album and see if this changes the display in cover flow. Suspect it may do!
Thanks again cynic.
If anyone knows how to get the artist displayed above the album title and still enter the correct info' in the correct tags then please help!

Cover Flow displays multiple copies of certain albums

I've tried everything to get it to stop doing this. All the tags are exactly the same, and it displays as one album in grid view, but in cover flow, all the songs are separated. Any ideas?

+All the tags are exactly the same+
I'll take your word for it and assume you've read this article
http://support.apple.com/kb/TS1468
So in your case, highlight all the tracks, right-click > Get Info > Options tab
Check off "part of a compilation" and save the changes. Then go back and uncheck compilations and save it again. Sometimes that comp thing fixes it for me.

Problem using iTune Cover Flow display

Previously iTunes "Cover Flow" allowed me to view album convers.

I am able to see album covers in "Album List" and "Grid" displays.

Cover Flow display issue

Can anyone explain the distortion I'm seeing in the album images in Cover Flow? I don't have very up-to-date video card, but it doesn't /look/ that complicate to render.

Cover Flow missing/not displayed

I'm using iTunes 8.1.1.10 on Windows XP. I have been using iTunes for a while with Cover Flow working perfectly, but today I opened it to try and add some new tracks and to update the cover art but it isn't displaying any image at all.
I have looked up similar problems and they seem to focus on iPods or display the temporary "?" image instead of the uploaded art. But my problem is a complete absence of anything. When I use the grid option it displays album art fine. When I open the "Get Info" artwork tab or select the Cover Flow display option it is blank.
I hope someone can help me with this.

So... not necessarily the right solution for everyone but mine is fixed. First of all I got a clue when I tried Google Earth, and none of the rendering modes worked, suspicious when I already had a graphics issue with iTunes.
I have no idea what caused my issue, but first I tried installing DirectX... no success. Next I took the pretty radical step of uninstalling my graphics card (slightly worried as I don't have my backup disc with me! After a couple of restarts and putting all the settings back to the best for my monitor I tried google earth, it worked, iTunes next, and they are all back, album art is now being displayed on Cover Flow.
Again... I don't think its the best solution for everyone, but if anyone has this issue and google earth is having issues starting then I'd probably recommend giving this a go.
Thanks for the help everyone, happy iTunesing!

Strange cover flow behavior

Just got a 32 GB iPod Touch, and I'm encountering an odd bug with cover flow. For example: say I want to play Amy Winehouse's "Back to Black". If I choose the album from list view, the correct artwork comes up. If I flip horizontal and look at cover flow, for some reason it displays the cover of Miles Davis & John Coltrane: The Complete Recordings. If I then tap in the info button to see the song list, the miniature version of the cover art in the upper right hand corner is the correct Amy Winehouse cover.
The iPod seems to have a perverse sense of humor ... it has assigned the Sex Pistols's "Nevermind the Bollocks ..." the cover of the Beatles' "Rubber Soul"!
Again, this is only when viewing in cover flow ... the miniature version on the info page is fine, as is the artwork that displays when the ipod is vertical.
Incidentally, I also have an iPhone, with some music that is on both ... and the problem does not occur with cover flow on the iPhone. Weird, no?
Any ideas? I've tried copying over the correct artwork doing a select-all in iTunes, but no joy.

I have the exact same issue, and a cover art variation on my 8gb touch I got in September.
It ****** me off enough to restore my iPod, restoring it to defaults fixed the messed up artwork, but I don't know how long it will stay. However, it also created a new problem of some artwork not syncing at all.

Blurry Cover Flow Scrollbar on Intel-GMA Macs?

I noticed many people are suffering the blurry cover flow scrollbars in iTunes ever since 7.0.0, it never got better even in 7.1. While other people are saying no problems at all no matter what they do.
Also it seems this bug only happens on Macbooks and Mac-minis, both of which are using intel-GMA graphic cards. I don't know what Mac are being used in the development of iTunes, but I think Macbook Pros and iMacs are preferred. The developpers may never know this. And I think the difference between intel Graphic Units and independent Graphic cards may lead this problem.
Let's hope developpers to solve this. Does this problem happen on other kind of Mac?

I had actually not encountered this little quirk until I updated my Mac mini to 10.4.9... when I did, this occured. Happens in the iTunes window (which is temporarily fixed by adjusting the Cover Flow display size) and in full-screen, both the scrollbar and the volume toggle are blurry. Updated from 7.1 to 7.1.1, same thing. Tried in another user account, same thing. I deleted my root-level cache (/Library/Caches), same thing. Aside from totally re-installing iTunes, I'm at a loss as to what to do, and it's such a minor thing that re-installing the application seems pretty drastic. Hope someone figures this out. Definitely gonna keep plugging away at this, though, and I'll post if I figure out if there's a fix for this.

Cover flow on computer doesn't work.

I am on a PC. When I attempt to use the Cover Flow display option my screen looks like this.
I just updated to the latest iTunes version (10.3.1.55) and I still have the same problem. Is there a way to fix this?

Cover flow view problem

I'm having an issue with cover flow view of images in OS 10.6.8
Whenever a jpeg or tiff file is edited in Photoshop (image size not changed) the preview of that picture in cover flow view
becomes smaller, pixelated and it never clears up.
Cover flow displays Raw camera files and unedited jpegs & tiffs correctly, only when an image is edited does it's preview in
cover flow become distorted.
I really like to use cover flow to browse through photos quickly but this issue is bugging me.
I've been on Photoshop forums and they say it's an Apple issue. So I don't know where the problem is.
Any help would be appreciated.

I know this paste below doesn't directly respond to your issue, but the steps below will restore OS X with a new copy and possibily clear up your issue.
There was a recent security update and it's doing very strange things, in your case it will restore a new OS X copy.
Security Update 2012-001 Bricks Rosetta programs
I've outlined the restore proceedure here, it covers a lot of bases and explains what is going to occur so please don't be intimidated it's a LOT easier that it appears.
Take your time and comprehend the steps involved and you'll be backup up like before in short order.
Restore method.
#1 Backup your personal data off the machine.
Backup files off the computer (not to TimeMachine). If you don't have a external drive, get one and connect to the USB/Firewire port and simply drag and drop copy your User folder to the external drive, it will copy all your files. It's best to have two backups of your data off the machine when trying to restore.
Disconnect all drives now to prevent any mistakes from occuring.
#2 Try Restoring from a TimeMachine or hold option bootable clone
If you have TimeMachine drive, or a hold the option key bootable clone use that to erase and restore from before the Security Update occured.
Obviously if you didn't make a recent backup before the update, your going to have to skip to Step #3.
Note: A TM restore can take a awfully long time, a clone restore takes under 2 hours in most cases.
If you don't know how to restore from TM drive
http://pondini.org/OSX/Home.html
#3 Reinstall OS X 10.6 from disk
If no recent TM or bootable clone then:
Get out your 10.6 install disk and make sure it's clean and polished (very soft cloth and a bit of rubbing alcohol, no scratches) If your disk is borked, you'll have to order a new one from Apple with your serial number.
Hold c boot off the 10.6 disk (wired keyboard, internal optical drive), use Disk Utility First Aid to >Repair Disk and Permissions (do not format or erase!!), Quit DU and simply re-install 10.6.
Note: Simply reinstalling 10.6 version from disk (without erasing the drive) only replaces 10.6.8 with 10.6.x and bundled Apple programs, won't touch your files (backup anyway) or most programs, unless they installed a kext file into OS X itself. (only a few on average do this)
Note: If Disk Uitlity can't repair the drive, then come back to seek further assistance and make sure you have a copy of your data off the machine.
#4 Update to 10.6.8 without Security Update 2012-001
Reboot and log in, update to 10.6.8 via Software Update, but EXCLUDE THE Security Update 2012-001 by checkinig the details and unchecking the blue check box.
#5 Reinstall any non-working third party programs
When you reboot, make sure to reinstall any programs that require kext files installed into OS X, you'll know, they won't work when you launch them or hang for some reason.
If for some freakish reason you get gray screen at any time when booting (possible it might occur when you reinstall older programs), hold the shift key down while booting (Safe Mode, disables kext files) and update your installed third party software so it's compatible with 10.6.8.
https://support.apple.com/kb/TS2570
Note: For most users likley Step #3 and #4 is likley all that is needed to be done.
That's it really.

Unverified hacks
Note: You may see a "hack" for this issue floating around, it has had mixed results as people's software is different.
You may want to try it, but it's at your own risk. It has worked fast for some and not at all for others, hopefully over time it will work for all.
The above methods I outline are Apple approved restore methods + based upon experience here and not a quick fix, but are sure to work as Apple recommends such steps themselves.
If at any time you feel this is beyond your capability, please seek local Mac/PC professional assistance before you lose your data.
In fact my steps above are very simple, you might want to have a family member or friend perfrom the proceedure in about a hour or two.
If you don't have any backup, please maintain at least a TM drive, just hook up a new blank external drive and TM will ask you to make a backup, takes some time so let it work.
If your a bit more skilled, a option bootable clone is much superior than TM drive.
Good Luck
