IOS: action with enter key of iPad KeyBoard
You would typically assign your view controller as the text field's delegate and then implement the textFieldShouldReturn: method, e.g.:
- (BOOL)textFieldShouldReturn:(UITextField *)textField { otherTextField.text = @"World" return YES;}
You can do that by implementing the UITextFieldDelegate protocol in your controller. For instance you could do something like:
- (BOOL)textFieldShouldReturn:(UITextField *)textField { if (textField == theFirstTextField && [textField.text isEqualToString:@"Hello"]) { theSecondTextField.text = @"World"; } return YES;}
Set your view controller to be the textfield's delegate then implement
-(BOOL)textFieldShouldReturn:(UITextField *)textFieldthis gets called when the enter button is pushed on the keyboard.
