UITextfield disappears

I have some UITableViewCells with some UITextFields inside. I am also using the code from UICatalog for the keyboard to not hide the UITextFields. The "Done" button on the kyeboard closes the keyboard. Now to my problem.
First I enter some text in a textfield and then I don't tap the "Done" buttin, I just scroll down so that textfield will become outside of the screen. Then I enter text in another textfield and scrolls up again. Now the first textfield is wiped out and has disappeared. It doesn't seem to happen when using the "Done" button.
I can't understand why this is happening, anyone else got the same problem?
Thanks for your help!

I think this thread answers the issue: http://discussions.apple.com/thread.jspa?messageID=8068400.

Hide keyboard when UITextField is selected

I am able to hide the keyboard when the user clicks off of a uitextfield by using the [sender resignFirstResponder] command, but I want to hide it as soon as the user clicks inside the textfield. Is this possible?
I have the uitextfield "Editing Did begin" etc etc set up to call a method and that is using the same commands ( [sender resignFirstResponder] ) but the keyboard never disappears? I can see the method is being called and the commands are being run but the keyboard just stays there.
I want to call another method to change views when the user selects the uitextfield. The view changes but the keyboard is up and will not go away.
Any suggestions?
Thanks

Well, I created a dummy custom button on my interface and when the textfield is selected this method gets called and the Log message is output to the console but the keyboard comes up and remains up no matter what. I tried to refocus to the button and resign the textfield as the firstresponder but no luck. Is this something just so apparently wrong with this code?
-(IBAction)showDatePickers:(id)sender
NSLog(@"Inside showDatePickers: %@", sender);
[dummyButton becomeFirstResponder];
[departureDate resignFirstResponder];
//[[RootViewController sharedRootViewController] loadDatePickers:sender];

Disappearing class variable

Next problem. Sorry to keep posting here - hopefully I'll get things figured out to the point I don't have to so often soon. Anyway, I have my MainViewController class which has a number of variables in it. One of said variables is a NSDictionary, usersDict. All the other variables work fine and retain their values, but for some reason whenever I leave the function usersDict is instantiated in, it seems to disappear - at any rate, if I try to use it in any other function (other than assignment) the program crashes. For example, if I call NSArray *tempUsers=[usersDict allKeys];, the program crashes, unless called in the same function usersDict is instantiated in, in which case it works perfectly. I am instantiating usersDict like so: usersDict=[NSDictionary dictionaryWithObjectsAndKeys:@"in",@"Israel",@"out",@"Joshua",@"over",@"Robb",nil]; Is this correct? I have tried putting this code into the viewDidLoad function, as well as the initWithNibName:bundle: function, with the same results. What am I missing this time? My class declaration is as follows:
@interface MainViewController : UIViewController <UITextFieldDelegate, FlipsideViewControllerDelegate>{
UITextField *textField;
UILabel *timeLabel;
UILabel *testLabel;
NSTimer *updateTimer;
NSDate *currentDate;
NSString *punchtype;
bool useTimeRounding;
IBOutlet UIButton *punchButton;
NSDictionary *usersDict;
NSManagedObjectModel *managedObjectModel;
NSManagedObjectContext *managedObjectContext;
NSPersistentStoreCoordinator *persistentStoreCoordinator;
@property (assign) NSTimer *updateTimer;
//@property (nonatomic, retain) NSDictionary *usersDict; //Try just for testing
@property (nonatomic, retain) IBOutlet UITextField *textField;
@property (nonatomic, retain) IBOutlet UILabel *timeLabel;
@property (nonatomic, retain) IBOutlet UILabel *testLabel;
@property (nonatomic, retain) NSDate *currentDate;
- (IBAction)saveAction:sender;
@property (nonatomic, retain, readonly) NSManagedObjectModel *managedObjectModel;
@property (nonatomic, retain, readonly) NSManagedObjectContext *managedObjectContext;
@property (nonatomic, retain, readonly) NSPersistentStoreCoordinator *persistentStoreCoordinator;
@property (nonatomic, readonly) NSString *applicationDocumentsDirectory;
- (IBAction)startRepeatingTimer:(id)sender;
- (IBAction)stopRepeatingTimer:(id)sender;
- (IBAction)setTime:(id)sender;
- (IBAction)recordPunch:(id)sender;
- (IBAction)showInfo;

If no one asked questions here, what would be the purpose of the forum? Your question is a good one and the solution is likely to help many other developers besides yourself.
usersDict=[NSDictionary dictionaryWithObjectsAndKeys:@"in",@"Israel",@"out",@"Joshua",@"over",@"Robb",nil];
Since you're obtaining usersDict with a "convenience" method instead of alloc, you can assume that the object is autoreleased. That means you must either finish using the object before the end of the current event cycle, or you must retain it. The above statement doesn't retain the object. The correct way to retain usersDict (as well as ensuring it's released at some point) is to use a setter method when saving the dictionary in an ivar. E.g.:
@interface MainViewController
NSDictionary *usersDict;
@property (nonatomic, retain) NSDictionary *usersDict; //Try just for testing <-- Not just for testing; this is a keeper
@end
@implementation MainViewController
@synthesize usersDict
- (void)dealloc {
[usersDict release];
- (id)initWithNibName
self.usersDict=[NSDictionary dictionaryWithObjectsAndKeys:
@"in",@"Israel",@"out",@"Joshua",@"over",@"Robb",nil];
Note self.usersDict on the left side of the assignment. The dot syntax is equivalent to calling the setter method, i.e. [self setUsersDict:[NSDictionary...]; Direct assignment (usersDict=) doesn't invoke the setter and therefore doesn't retain the object.
Here's a link to one of my recent posts on the difference between allocing your "own" object and obtaining an object with a convenience method. By far the most valuable part of that post is the link to the Cocoa Memory Management Guide.
Hope that helps!

Downloads disappear from folder

I have downloaded some music and when it has completed the task, the download file disappears. Hasn't done this before, files always remain in download folder.

Launch Finder.
Finder > File > Find
When the Finder window opens up, enter the name of the music file in the search box at the top right corner.
It will show up in the Finder under “Name”.
Right click on it and select “Reveal in Finder” from contextual menu.
The resulting Finder window will show the location.

On Screen Keyboard Glitch in Tablet Mode - On Screen Keyboard minimizes / disappears / slides down

Hi there -
New Yoga owner here ( just bought it yesterday) and within minutes of setting the computer up I noticed that the on screen keyboard was malfunctioning when the yoga is in tablet mode. Specifically, it pops up for about a second and then, without me touching or clicking or doing anything, it quickly slides back down. repeated attempts to bring up the keyboard end up, frustratingly, with the same result. what is perplexing to me is the on screen keyboard works fine in laptop mode (when I need it least).
Someone else already started a post on this BUT it was marked as 'solved' (which it wasn't) so I figured I'd start new thread. The solution on the previous thread was to simply 'refresh' windows to get rid of any new drivers that were downloaded since purchasing the yoga, but I did not download or update anything prior to this problem arising (as I said, the problem seemed to occur within a few minutes of turning the machine on for the first time). In any case, I tried the refresh and it did not work so clearly my problem is not that I downloaded an incompatible or faulty driver. Please Help! I love this machine and I'm trying to see past the other flaws I've noticed so far (subtle screen flickering, inconsistent touch sensitivity etc), but this issue is starting to really undermine my confidence in the product quality and, from a productivity standpoint, it is a real deal breaker to not have full tablet functionality.
Solved!
Go to Solution.

I had the same problem with the disappearing virtual keyboard within hours of starting to use my new Yoga 13. I read somewhere that it was a problem with an incompatible Synaptics driver, and when I looked in the control panel, it showed that the Synaptics driver had been updated on my Yoga as of the day I bought it. I think somehow by agreeing to automatic updates of the software, the Synaptics driver is updated to an incompatible version. So what I did was I removed the Synaptics driver, using the Windows program uninstaller tool, rebooted, and then found the Synaptics driver at the Lenovo site which is specifically labelled as the Yoga 13 driver. I installed that, and the keyboard is now working fine.

When I attempt to click on itunes, it appears on the dock, bounces, and disappears. This also occurs with the "help" application. Can anyone help? Here is the crash log, but b/c it is so large it is pasted here with only the first ever crash and the most recent.

Looks like your webkit framwork is broken, or is now broken in relation to iTunes. Calls and classes may have changed since version 7.1, which is what you are using. Try updating to the latest version of iTunes and see if this fixes it.

When I open up my emails and close them, they disappear and I cannot find them. Where are they going? Is there a setting that I have to change?

Once I open up my emails they disappear and I cannot find them anymore. Is there a setting that I need to change to stop this from happening?

Are you tapping any of the icons at the of the Mail app after opening them, or do they disappear without you doing anything ? And if you have more than one account on the iPad, does it happen on your other accounts as well ?

Contacts and calendar events disappearing and reappearing

I have three issues, two of which I think are related.
1.
My contacts disappear on my iPhone 3G. I am set up with MobileMe to auto sync and I don't know if that is getting screwed up somehow? The contact are on my Mac lap top when I go look (thank goodness), and I force a sync and they transfer to my phone fine. This has happened twice now. I have copied my contacts as vCards and saved that file in the downloads folder just in case they get lost on both my laptop and my iPhone - I also do a regular full laptop backup to my Time Machine - is there anything else I should be doing to back up my contact and calendar data?
2. (possibly related to 1.)
When I am looking at my iCal in the weekly view on my laptop, sometimes several of my appointments are not visible. It is only when I try to put an appointment in that is at the same time as the invisible ones that they suddenly reappear.
3. One of my contacts will not sync from my iPhone to my lap top? It used to be in both places but for some reason it is now only on my iPhone and even when I sync, it doesn't come into my laptop Address Book.
Help please!!!

i am having what i think is a very similar problem in that my Exchange (you seem to use only mobileme) contacts partially disappear. i discover this when i check my sms message list and find that many messages show only the phone number when earlier the name was there. a check of the contacts list shows that some have disappeared.
i restarted the phone and checked immediately but it was still gone but after a few minutes they came back.
my theory is that something is going on with messy exchange server syncs with my iphone that could be causing the process to break midway but after a while the phone automatically syncs again.
this issue appears quite rarely for me but enough to be noticed and to be annoying.

I just updated itunes and a LOT of my movies and music disappeared. These are movies and music I owned already and did not purchase from iTunes. How do I find them or do I need to add them all again? Also what happened to the sidebar?

I just updated my iTunes software and have a lot of problems...
1. The sidebar option is gone. I LIKED the sidebar and it was easier for me to navigate that way.
2. Also no lists? I hate the icon way to view it. It makes my eyes go wonky and I have a harder time actually looking for what I want.
3. A LOT of my music and movies have disappeared. These are music and movies I owned that I did NOT purchase from iTunes so I can not re-download them.
How do I find the missing files? Do I have to readd them into iTunes? Is there a way I am not seeing to put thew sidebar back or make the files be viewed in list form? Can I undo this update to put it back the way it was. I hate this update...

See my answere to your post in the Mt. Lion forum.

ICal disappears in month view

Just recently, when I select month view in the Tiger iCal, the window disappears. I can add new events, but cannot see them unless I'm within the day or week view. Also, when I immediately click day or week, it doesn't fit the frame properly. Does anyone know why this glitch is happening?

I found this advice from a standford prof.... and it worked for me...
"I just deleted the com.apple.ical.plist file from
user/library/preferences and reset everything back to defaults and it works
fine now."
I deleted all the iCal plists and it kept my data, but reset iCal and I can now see in month view.

If e-mail is moderately long if I delete a letter or digit the cursor disappears, have to recover it, all deleted letters or digits appear at end of e-mail

If I type a moderately long e-mail (I haven't counted the letters/digits to determine how long), then suddenly letters won't appear. If make a typing errors, and backspace over or delete the error/s, the cursor will disappear. It's not anywhere in the body of the e-mail (or anywhere else I've noticed). I can get it to reappear by highlighting every word in the e-mail, then undoing that.
All the letters/digits I've deleted reappear at the end of the e-mail--but only in the e-mail received (by the recipient). If I save the e-mail as a draft, when I look at the draft, the I'll see the deleted letters/symbols at the end of the e-mail. If I click on edit, they disappear. But recipients see all of them, regardless of whether I edit the e-mail or not.
The last time I asked this "question", I was told to update. That was probably 5 updates ago. There has been no change.
I don't know if the problem persists in safe mode because I have forgotten to switch into safe mode every time I use TB. Sometimes I remember to run TB in safe mode but don't have reason to type a long e-mail.
I'm really tired of this problem.
OS is win 7 pro w/service pack 1.

May I ask why? Have you learned that that specific problem is solved in a pre-release version? So far I've upgraded once on your advice, now I've upgraded again to 31. Problem's still there. Unless I'm told that the problem's been solved for sure in a latter version, I'm not going to upgrade because sometimes the upgrades bring problems w/them for a low tech user. I don't want to chat, etc., I just want to be able to send and receive e-mails.
I'm still working with the security software people re: some continuing issues w/FF.
I'd like to spend more time doing my work, or communicating w/friends, not dealing w/software problems.
Is there anyway of my finding out what, if any update, includes whatever is needed to solve my specific problem? I use Win7 Pro, SP1, 3.40 Gz processor, 3.19 Gb usable RAM, 64 bit OS. I don't know what other information is needed.

Ipod touch will no longer sync my songs, they show up for a few seconds then disappear help

for some reason when I try to sync my songs to my ipod touch, they will all show up briefly, then disappear once I hit the sync button? very frustrating, have never had this problem in the past, any suggestions would be great

If you haven't tried it yet, I'd eliminate memory issues first. Close all of the apps with the double tap on the home button method

Can no longer connect to my network and "forget network" option has disappeared??? (Ipod touch 5th generation). This happened on both my children's ipods. We have reset network settings but it doesn't help.

JEM24 , your suggestion is included in:
- iOS: Troubleshooting Wi-Fi networks and connections
Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
