Hide keyboard programmatically in iOS

1. Add the following code to the implementation file (.m)

-(void) textFieldShouldReturn:(UITextField *)textField

{

    [textField resignFirstResponder];

}

And in the header file (.h)

-(void)textFieldShouldReturn:(UITextField *)textField

2. Add target to the textField:

txtField.delegate = self;

[txtField addTarget:self action:@selector(textFieldShouldReturn:)

          forControlEvents:UIControlEventTouchCancel];

That's it! Test it out. Hope you find this useful.
