Beginner "Hello Camera" App Sample Errors

Hello,
Can anyone help me out. I was trying to recreate the "Hello Camera" app sample but I keep getting these errors. I'm assuming that the instructions follow those necessary for an earlier version, especially because of all the deprecation errors. I thought I fixed the codes to the new ones being used in Xcode 5.0 though. I've tried looking up how to fix these errors and I can't find anything that helps. If anyone can help I'd really appreciate it.
Thank you!

Your errors do not match the lines indicated. Try to clean project and rebuilt. Aside from that, your errors look pretty straightforward. Follow the suggestions to fix them.

It's a built-in app, so it can't be deleted nor downloaded from the store. If you can't find it on any of your homescreens or app folders, and you can't find it via the spotlight search screen (swipe your first home screen to the right), then is it hidden by Settings > General > Restrictions > Camera being set 'off' ?
If not then have you tried a reset to see if you can find it after the iPad has restarted ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

In app purchase, error "contact Itunes store support to complete your purchase". But I have bought many already then suddenly came this error msg. Why?

Camera App - Not Working "error.4003"

I am receiving the error.4003 for the camera app. This affects both camera and video modes. The front facing camera does not work through the camera app, but works fine if used via the video chat app. This appears to be a software error as the touch screen interface controls in the camera app are not completely functional or have a severe response time lag as compared to normal touch screen response time.
Apparently worked fine a month ago. Pictures taken looked great.
At first the error message received on the camera app stated camera was already in use. Not the error above is all I get.
I've done research via the Web and the only responses thus far is to send this into RIM. But too many people are experiencing this error and the posted ideas on other forums are either questionable or IMO not acceptable.
Also the screen capture cameramode works fine. No problems.

From everything I hear 4003 is a "hardware" malfunction.
It happened to me as well right AFTER the 1032 OS upgrade - how's that possible>?
Probably blows a resister or something.
I had warranty left -and got a brand new Playbook in return this week. The turnaround took only a few days by FedEx.
Why so fast? It can't be fixed - so they're just tossing the old ones and replacing them.
I received a brand new identical model (32g) - however it wanted to go to the 1032 upgrade step during intial setup.
i was hoping to avoid that. Did it anyway - no choice.
Happy to report - cameras are both working.
NO explanation of the hardware fault by RIM - what it is or what causes it.
If you have warranty - just call support. They're breaking it somehow - it's not YOU!
Get it replaced before your warranty runs out.

How Do I Wrap Text Like the iOS Camera App?

Hello. I am in yearbook, and I have been challenged with designing the cover of the yearbook, and I have been having a few problems along the way. One of these problems is to wrap text. Specifically, I'm stuck on how I would wrap text like the iOS camera app on the bottom of the screen. The words seem like they are wrap around a 3D object to give it that effect, but I can't really tell. If anyone can help me, it would be greatly appreciated.

There is a big difference between being a casual user than real work or development. I own a iPod its a great MP3 player and a device I can display my pictures on out of my pocket. I'll even Facetime my kids at time to see my grand kids or help fix something. My wife has a mini iPad for quick internet access and quire music and uses her iPod to entertain our two year old grandson with games. She uses a Canon 1D mark 4 and I a Cannon 1D mark II. The only use the iPad and iPod cameras get is Facetime. No iOS apps are use to work on images they have no value when you have Photoshop. The iPod is better for displaying image then the iPad mini it has a 3:2 aspect ratio display and travels better the the mini iPad which has a 4:3 aspect ratio display. I also crop image for display on wall mounted HDTV. The iPad is better for casual internet access then the iPod. All our kids have iPhones and they all use computers either Mac or PC for work and internet access. When you have a Unix or Windows why would you want to touch an iOS device for work or serious internet access. Apple mobile devices are convenient for casual use and grand kids don't get that dirty finger painting on them as they do using real paint. Nothing of real value is maintained on an iOS device.
Well...there's Photoshop Touch and Photoshop Mix as well as Lightroom Mobile. It could be argued that they're don't exactly mirror their desktop cousins, yes, but they weren't meant to be. They were meant as extensions to the desktop experience. (e.g., Lightroom Mobile lets one work with the RAW images they have in their Lightroom desktop collections.)
The more powerful Windows tablets can run Photoshop desktop (like Photoshop CC) too.
@bluebocat: Are you looking for text with a perspective? Like it has a vanishing point? As if it was turned in a certain direction in 3D space?

IPhone 5s camera app won't open and crashes from lock screen and control menu

Hello, I recntly got a Black iPhone 5s 16gb and it was working fine. Then sudenly the camera app started crashing after i took photos. Soon later the camera app wont open at all and if i try opening from the lockscreen the phone just reboots. Ive tried just resetting all settings just off the phone and nothing happened, so i decided to restore my iPhone to factory settings and still had no luck. I also had a problem with the flashlight it stopped working aswell (went gray on control menu) and all flashlight apps wont even. I also found out that my snapcat front camera (selfie camera works) and there is no 'swap button.
This is the second time Ive been suffering from a camera issue the first one was ery similar the shutter wouldnt open because there was no memory, but now ive got 9.1GB free so this cant be the problem. Other reviews i have read state that the phone has a hardwear issue and need to be replaced.

FIX FOR REAR CAMERA AND FLASHLIGHT!!!
I also had the same flash and rear camera problems as everyone else but I figured it was a software problem.
To fix the flash/flashlight, simply download the flashlight app. The one everyone used before iOS 7. The flash should work immediately.
To fix the rear camera go to Settings > General > Restrictions. Enable restrictions and turn the Camera off, then take the restriction off. Check your camera, it should work immediately.
Hope this answers a lot of questions and saves a bunch of money due to Apple's failures.
Cheers,
Tim

Camera app doesn't work after installing a new screen

I have been fixing broken iPhone screens for quite some time now but have never come across something like this. After installing a new screen the camera app won't show the camera and the shutter never opens. I thought I didn't put one of the cables in right so I double checked and sure enough they were in good. I restored the phone and tried it again with no luck. I then switched out to another screen I found and the camera worked perfectly. This is so bizzarre to me but can anyone explain to me what is wrong? Or what has happened? I have never seen anything like this.

I keep getting an error message of (0xE80000001)!
Read here. iPhone, iPad, iPod touch: Unknown error containing '0xE' when connecting

Time Issue not just on Alarms – camera Apps too.

I noticed that the summertime switch, which breaks some alarms not only affects the alarms. Recently on a trip to Europe, I also noticed that photos taken with Hipstamatic also don't accept the 1 hour difference. So if you take pics with the normal camera app and Hipstamatic at the same time, the Hipstamatic ones will be 1 hour out. haven't tested other apps yet.

Hello Enamic,
Time problems after the summertime change are common.
Try to move your time zone. After you're done, move the clock back one hour.
I hope this will help.

IPhone Camera App Crashed...

Hello, I was taking some pictures with the iPhone camera app when all of the sudden after taking the picture, the camera app closed and the iPhone screen showed the shutdown spinwheel for a few seconds and then returning the the unlock screen. When I reopened the picture app, the picture that I took before the crash was gone. What could have cause this crash issue? but most importantly where's the picture? is it gone or was transmitted to somewhere else (folder, camera roll, iCloud, etc.)?
Thanks for the assistance!
P.S. I am looking at the iPhone logs and see that there was a springboard crash near the time of the crash. Can a springboard crash cause the iPhone to show a shutdown spinwheel and then leave you back in the log in screen?

I am using iOS6.1.1
Can you try to load up the apples and try take some HDR photos.

Launch Camera App / Insert Image(s)

Hello,
I did some browsing but was not able to find something similar to the question I have.
I have a client who would like me to build some .PDF form(s) for his construction crews. The objective is to eliminate all the paperwork they currently have (not a problem with fill forms and Reader on their Apple tablets).
But here is where I run into a problem trying to create what he wants / needs. He wants the the user to have the ability to launch the camera program from within the .PDF form in Reader, snap the photos needed with their tablet, and insert them into the form. While I have found some java script that will allow them to click a "button" in the form and insert a .PDF, they really need the ability to insert the .jpg images taken by the tablet's camera.
With that said here are my goals:
Create a button that will launch their camera app allowing them to take photos of the job site
Insert the photos they take into the form - this can be a blank document page(s) just for the photos
Save the .PDF form and use a button to send the form. Email is the only option to send a form I believe??
I am using the latest versions of Adobe CC products (for windows) including Acrobat Pro XI, InDesign, Illustrator etc. to create this job. As I mentioned above, my client will be using Reader on Apple tablets.
Thank you in advance for any help you can offer.
Adam

Hello,
Thank you for your response!
I have considered an HTML / web based version instead of the .PDF option, but there are often times they do not have internet access, and would be required to save the file(s) to send them once they do have internet access.
Here is my plan B...
If I use a standard send form button which launches their email program, they could then attach the photos to the email and send the form and photos together. While this would be a fairly simple solution, they goal of the business owner was to keep this as simple as possible for the crews. Although, I would think that any solution would be better than filling out paper forms in triplicate
Thoughts on this option, or maybe a more streamlined way of implementing this idea?
Thank you again
Adam
