Question

I want to disable input pad on iphone when pressing ‘done’. Any ideas about how to detect button press event?

Answer 1

Programatic Method

To register button press events you can either do the programmatic approach:

[button addTarget:self action:@selector(buttonPressed:) forControlEvents: UIControlEventTouchUpInside] 

Where buttonPressed: is a method in the class ‘self’:

-(void)buttonPressed:(id)sender; 

You can specify a pointer to any object instead of ‘self’ of course, as long as the object has a buttonPressed: method.

Interface Builder

You can also use Interface Builder. Create a method that you want to execute:

-(IBAction)buttonPressed:(id)sender; 

Then right click on the button in interface builder. You should see a list of actions. On the ‘touch up’ action click on the circle button, and drag a connector to the object representing the class where you put the buttonPressed: method.

Disabling Input Pad

I’m not sure what you mean by this. Are you talking about dismissing a keyboard input? If so, you have to call the ‘resignFirstResponder:’ method. Say, for example, the keyboard pops up because you are editing a text field. To dismiss the keyboard call the following method on the text field:

[textField resignFirstResponder];
