Question

Hello all,

I have one view name:myplay.h and myplay.m

my view contain one textfield name txtplay..

It contain one button name btnplay.

In button event i want to check that if uikeyboard is open then close it.

I know below code

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
   [textField resignFirstResponder];
   return TRUE;
}

and in button click event

-(IBAction)btnplayclick:(id)sender
{
  [self.txtplay resignFirstResponder];  
  ....
  ....
}

I want a global code to resign.
