UITextField text disappears on every other keystroke

Question

Here is a video of the phenomena: http://youtu.be/c0TP8YVF9TE

As the video shows, the value in exampleTextView.text is not lost. Its just hidden every other keystroke.

Solutions tried: I do not set the exampleTextView.text value to something during the program, except after the return key is pressed (and commenting that line out changes nothing).

I have set:

self.exampleTextView.clearsOnBeginEditing=NO;
self.exampleTextView.clearsContextBeforeDrawing=NO;
self.exampleTextView.clearsOnInsertion=NO;

Edit: Here is my code: https://gist.github.com/andrewschreiber/6970283

I think community people can help you if you show us your code. — Kyokook Hwang, Oct 14 '13 at 02:44

I had almost the same problem. Sometimes the text was disappearing.

I solved it after changing the position of the UITextField in the view hierarchy in the xib file.

This is very strange. Just to clarify, this fixes the problem if you want to call `becomeFirstResponder` in `viewWillAppear`. The answers below work as well moving the call to `viewDidAppear`. – WCByrne Dec 16 '14 at 16:34
What a shameful bug on Apple's part – cph2117 Jul 24 '15 at 15:05
This still solves the issue for Xcode 7.0.1 storyboards. Thanks! – Matt Long Oct 08 '15 at 04:19
This was not the case for me. Mine was at the bottom of the list. The other solution by user3339688 did work for me. – jungledev Apr 27 '16 at 21:06
This worked for me. Moving textfields to be topmost ui element worked. Crazy. – Denis Jul 30 '16 at 22:32

I was facing the same problem. My solution was to remove [_textField becomeFirstResponder] from the - (void)viewWillAppear:(BOOL)animated method. This bug only occurs if the viewcontroller was presented modally.

Yes if you want to make that text field first responder than make it in viewDidAppear instead of viewWillAppear. Your problem will solve. – Chandni - Systematix Nov 23 '16 at 06:48

Moving the UITextField's becomeFirstResponder from viewWillAppear to viewWillLayoutSubviews fixed this for my case. I also made sure to add resignFirstResponder on the UITextField to the actions that were dismissing the view (which was presented modally).

I even had to place it in viewDidAppear. Otherwise it resulted in invisible text. – wolfrevo Nov 19 '14 at 22:49

Try to use all the Delegate method of UITextField . and please let me know what are you trying to do with Done Button clicked , only set the text of anything else or if you share all the code with me then i can help you

Please replace your textFieldShouldReturn method with my method and also implementing the textFieldShouldBeginEditing method in your code and its working fine

 -(BOOL) textFieldShouldReturn:(UITextField *) textField {

          [textField resignFirstResponder];
    }


- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {


    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.5];


    [UIView commitAnimations];

    return YES;


}

I tried this, both with 'return YES' and 'return NO' in textFieldShouldReturn. That did not solve the problem, but gave me some ideas to try. — Andrew Schreiber, Oct 15 '13 at 21:17

Solved the problem.

On my storyboard, I switched the text from 'Plain' to 'Attributed' then back to 'Plain' again.

This solution didn't work for me. The other solution from SbClx did. – nst Jan 16 '14 at 17:10
Ok, changed correct answer as others seem to have the same result. – Andrew Schreiber Jul 27 '14 at 02:03

@SbClx 's solution works for me, but I have another workaround that also works: set the background of the UITextField to any UIImage you like.

After some trial and error, I found that the bug disappears when I set the borderStyle of UITextField to UITextBorderStyleRoundedRect, which is unfortunately not what I wanted, I want a simple white background.

The documentation of UITextField.borderStyle states that: If the value is set to the UITextBorderStyleRoundedRect style, the custom background image associated with the text field is ignored. So I guess background image might have something to do with the bug too.
