UITextField calls textFieldDidEndEditing when cleared but `text` property has data

Question

Did anyone notice that UITextField calls textFieldDidEndEditing after clear button is pressed but text property still has old data ?

I'm not sure what code-sample I can provide here. I'm using storyboard if that matters.

For now I have to rely on taking data from all edit controls on main form's "Submit" button. But ideally I'd prefer to collect data in textFieldDidEndEditing handler.

Are there any better workarounds ?

I'm on iOS 6.

Update: Basically here is what I have on the form

• UITextField and UiButton are on the form.
• Keyboard dimissed by calling resignFirstResponder in handler of UITapGestureRecognizer

Steps to reproduce the issue:

• Click on edit control. Enter some text.
• Tap outside of text control.
• textFieldDidEndEditing is called. Property .text has value I entered. All good.
• Click on edit control again.
• Click on clear button.
• textFieldDidEndEditing is called again. But property .text still has value I just deleted !
• Now as you see cursor blinking inside UITextField tap on Button on the form.
• Keyboard is dismissed by textFieldDidEndEditing was never called.

I'll upload sample project on GitHub tomorrow.

Answer 1

I ran into the exact same problem. In my case, at least, it was due to having added a UITapGestureRecognizer to self.view (to allow for dismissing the keyboard if tapping outside of a UITextField) and setting cancelsTouchesInView=NO on the gesture recognizer. I had set that property in order to get hyperlinking working on a TTTAttributesLabel I have elsewhere in the View.

My workaround was to watch for keyboard show and hide notifications, and toggle that property accordingly:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShowNotification:) name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHideNotification:) name:UIKeyboardDidHideNotification object:nil];

(sign up for notifications)

- (void)keyboardDidShowNotification:(NSNotification*)notification
{
    tapGestureRecognizer.cancelsTouchesInView = YES;
}

- (void)keyboardDidHideNotification:(NSNotification *)notification
{
    tapGestureRecognizer.cancelsTouchesInView = NO;
}

(handle notifications)

The only problem, behavior-wise, is that the hyperlink still doesn't work when the keyboard is displayed: touching it will simply dismiss the keyboard, not forward the touch to the link handler. But I can live with that. After the keyboard is dismissed, the link works fine.

Answer 2

First check UITextFieldDelegate is assigned or not, then

implement the textFieldShouldClear delegate and write the code here clear your textField

To do this you have to set the clearButtonMode property,

yourTextField.clearButtonMode = UITextFieldViewModeWhileEditing;
yourTextField.delegate = self;

Then implement the textFieldShouldClear delegate

.h file

@interface myViewController: UIViewController <UITextFieldDelegate>{
}

.m file

-(BOOL)textFieldShouldClear:(UITextField *)textField

    yourTextFeild.text = @"";
    return YES;
}

Answer 3

try here:

-(BOOL) textFieldShouldReturn:(UITextField*) textField
