    copied!<p>I have a UIViewController subclass that I am trying to have handle the shake event when its view is up. </p> <p>Here are the relevant methods I've implemented:</p> <pre><code>- (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [self becomeFirstResponder]; } - (void)viewDidDisappear:(BOOL)animated { [self resignFirstResponder]; [super viewDidDisappear:animated]; } - (BOOL)canBecomeFirstResponder { return YES; } - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event { if (motion == UIEventTypeMotion &amp;&amp; event.type == UIEventSubtypeMotionShake) { NSLog(@"%@ motionEnded", [NSDate date]); } if ([super respondsToSelector:@selector(motionEnded:withEvent:)]) { [super motionEnded:motion withEvent:event]; } } </code></pre> <p>You would expect that when I hit ^+Cmd+Z in the iPhone Simulator that it would just log once, but it is consistently logging twice for each event. Below is the result of three "shake" simulations:</p> <p>2009-10-09 20:52:06.216 TestApp[39802:20b] 2009-10-09 20:52:06 -0400 motionEnded<br> 2009-10-09 20:52:06.218 TestApp[39802:20b] 2009-10-09 20:52:06 -0400 motionEnded<br> 2009-10-09 20:52:07.689 TestApp[39802:20b] 2009-10-09 20:52:07 -0400 motionEnded<br> 2009-10-09 20:52:07.690 TestApp[39802:20b] 2009-10-09 20:52:07 -0400 motionEnded<br> 2009-10-09 20:52:08.001 TestApp[39802:20b] 2009-10-09 20:52:08 -0400 motionEnded<br> 2009-10-09 20:52:08.002 TestApp[39802:20b] 2009-10-09 20:52:08 -0400 motionEnded</p> <p>Has anyone seen this and, if so, how did you fix it? I'm using iPhone SDK 3.1 and Xcode Version 3.1.4.</p>
