//摇动检测
// 1. add/Override canBecomeFirstResponder, viewDidAppear 和 viewWillAppear
- (BOOL) canBecomeFirstResponder
{
return YES;
}
- (void) viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[self becomeFirstResponder];
}
- (void) viewWillAppear:(BOOL)animated
{
[self resignFirstResponder];
[super viewWillAppear:animated];
}
//2. Add motionBegan or motionEnded 方法到你的View Controller （模拟器中二者都可以响应， 真机iphone4中只能相应motionBegan）
- (void) motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if (motion == UIEventSubtypeMotionShake) {
[self shaked];
}
}
