IOS UITextField - reject user inputView

Question

I use a custom inputView for some text field, however, when I call resignFirstResponder in the text field, the custom input view does not reject ... any suggestions?

UITextField *f=[[UITextfield alloc] init]; UIView *view=[[UIView alloc] initWithFrame..]; [f setInputView:view]; //random example of how to set a textfields input view to a custom view 

After some research, this problem only occurs when working with the viewController presented in modal form ... it works fine otherwise ...

thanks

Instead of calling resignFirstResponder you should call endEditing: in the view itself or in any of its superviews. endEditing: will search for all subqueries for any view that has the status of the first responder and ask him to resign.

endEditing: accepts a boolean flag as a parameter. If set, this will force the first responder to resign; otherwise, you can let it maintain focus (if the input is invalid, for example). For UITextField, this is determined by the delegate method shouldEndEditing:

In general, a good template to use:

 - (void)saveAction:(id)sender { if ([self.view endEditing:NO]) { NSString *text = self.textField.text; // save text, login, do whatever } else { // show an alert (or rely on whatever refused to resign to inform the user why) } }

If you use a modal view, make sure that the keyboard is automatically turned off. Add this code to your controller:

 - (BOOL)disablesAutomaticKeyboardDismissal { return NO; }
