detecting the change of content of UITextField when the change is not made by the keyboard

Question

I have a UIButton and a UITextField,when the button is pressed the textfield\'s content string will be equal to: This is a test string

Answer 1

This is a pretty robust solution, but it should work. In your function that is called when you press the button...

NSString *string = [NSString stringWithFormat:@"This is a test string"];
if(string == textfield.text){
...
}

Or, you can us a self scheduler to check if it has changed repeatedly.
