UITextField calls textFieldDidEndEditing on cleanup, but the `text` property has data

Question

Has anyone noticed that a UITextField calls textFieldDidEndEditing after clicking the clear button, but the text property has old data?

I'm not sure which sample code I can provide here. I use a storyboard if that matters.

Currently, I have to rely on getting data from all the edit controls on the main Submit form. But ideally, I would prefer to collect data in the textFieldDidEndEditing handler.

Are there any better workarounds?

I am on iOS 6.

Update : basically this is what I have in the form

• UITextField and UiButton are in form.
• The keyboard has been replaced by a call to resignFirstResponder in the UITapGestureRecognizer handler

Steps to reproduce the problem:

• Click the edit button. Enter the text.
• Click out of text control.
• textFieldDidEndEditing . The .text property has the entered value. All is well.
• Click the edit control again.
• Press the clear button.
• textFieldDidEndEditing is called again. But the .text property still has a value that I just deleted!
• Now that you see the cursor blinking inside a UITextField, click on the button on the form.
• Keyboard rejected textFieldDidEndEditing has never been called.

Tomorrow I will post a sample project on GitHub.

Answer 1

I ran into the same problem. In my case, at least this has to do with adding a UITapGestureRecognizer to self.view (to allow the keyboard to turn off if you click outside of UITextField ) and set cancelsTouchesInView=NO in the gesture recognizer . I set this property to get the hyperlink working on the TTTAttributesLabel I have elsewhere in the view.

My workaround was to monitor the keyboard and hide notifications, and toggle this property accordingly:

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

(register for notifications)

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

(recording notifications)

The only behavioral problem is that the hyperlink still does not work when the keyboard is displayed: touching it will simply cancel the keyboard, and not drag it to the link handler. But I can live with it. After the keyboard is rejected, the link works fine.

Answer 2

The first UITextFieldDelegate check UITextFieldDelegate assigned or not, then

implement delegate textFieldShouldClear and write code here clear the textField

To do this, you need to set the clearButtonMode property,

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

Then run the delegate textFieldShouldClear

.h file

 @interface myViewController: UIViewController <UITextFieldDelegate>{ } 

.m file

 -(BOOL)textFieldShouldClear:(UITextField *)textField yourTextFeild.text = @""; return YES; } 

Answer 3

try here:

 -(BOOL) textFieldShouldReturn:(UITextField*) textField
