textFieldShouldReturn not being called in iOS

Question

We're trying to figure out how to get the keyboard to hide, but we're having problems getting the textFieldShouldReturn to fire. Why?

This is what has been done:

*.h

@interface MultiSalesViewController : UIViewController <UITextFieldDelegate> 

*.c

txtCardNumber.delegate = self;  - (BOOL)textFieldShouldReturn:(UITextField *)textField {     [textField setUserInteractionEnabled:YES];     [textField resignFirstResponder];     return YES; } 

Also, the textField has its delegate set to Files Owner in Interface Builder. One odd thing, is that the viewController's - (void)textFieldDidEndEditing:(UITextField *)textField is working.

How to get the hiding of the keyboard working?

Answer 1

I had the exact same issue and it was because I forgot to set the delegate for the text field in interface builder to 'files owner'.

Answer 2

I had the same problem and, as Warren Crowther suggested, I managed to solve it by holding down CTRL and dragging from the TextBox to the "File's Owner" label.

(Gosh, I miss Visual Studio sometimes...!!)
