UITextField text change event

Question

How can I detect any text changes in a textField? The delegate method shouldChangeCharactersInRange works for something, but it did not fulfill my need exactly.

Answer 1

[[NSNotificationCenter defaultCenter] addObserver:self 
selector:@selector(didChangeTextViewText:) 
name:UITextFieldTextDidChangeNotification object:nil];



- (void) didChangeTextViewText {
 //do something
}
