This is the line i am getting the crash.Please give me the solution for me

Answer 1

Make sure your textfield has connection like this below images,

Answer 2

This is how

 self.etCountry.delegate=self;

And add

 @interface YourViewController ()<UITextFieldDelegate>
 @end

Answer 3

You may check other threads , and their stack. My guess is that there is everything is fine with text field. Seemingly there seems a network call also in the background, maybe a callback block is not in the right format. That caused similar "hidden" crashes to me.
