Shake doesn't work when alert is shown

Question

I implemented shake gesture event. When shake occurs i do some stuff.

However if alert is shown I don't get event.

Here is what I have:

- (void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:YES];
    // Register for shake detection
    [self becomeFirstResponder];
}

- (BOOL) canBecomeFirstResponder{
    return YES;
}


- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {

    if (motion == UIEventSubtypeMotionShake){
         DLog(@"Shake ended");
    }
}

Is it possible to get shake gesture when alert is shown ?

At what point do you present the AlertView? is it in motionEnded? — Woodstock, Jul 25 '13 at 13:06

Try this

 - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if ( event.subtype == UIEventSubtypeMotionShake )
    {
        // Put in code here to handle shake
    }

    if ( [super respondsToSelector:@selector(motionEnded:withEvent:)] )
        [super motionEnded:motion withEvent:event];
}

- (BOOL)canBecomeFirstResponder
{ return YES; }

Is it ok to call motionEnded directly? – Woodstock Jul 25 '13 at 14:35
I'd refrain from calling motionEnded yourself. – Rehat Kathuria Jul 25 '13 at 16:11
