Preventing multiple buttons from being touched at the same time

Question

In iOS is there anyway to prevent a UIView containing multiple buttons (siblings) from being simultaneously from being touched? For instance, two non-overlapping buttons that are side by side can be tapped at the same time with two touches.

Answer 1

on view and all subViews

[view setMultipleTouchEnabled:NO];

EDIT: add code so other buttons ignore touch events

One way to do this is to send resignFirstResponder to other views in buttonPressed:

- (void)buttonPressed:(id)sender
{
    // Assumes that the view only contains a bunch of buttons that you want to disable 
    // while you handle the first touch
    [[self view] subviews] makeObjectsPerformSelector:@selector(resignFirstRespoder)];

    // Do some stuff
    ....
    ....


    // Re-enable all the buttons
    [[self view] subviews] makeObjectsPerformSelector:@selector(becomeFirstRespoder)];

 }

Answer 2

Set UIView.exclusiveTouch.
