一、实现系统自带的motionBegan方法
1 2 3 4 5 6 | /// 开始 - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event NS_AVAILABLE_IOS(3_0); /// 结束 - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event NS_AVAILABLE_IOS(3_0); /// 取消 - (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event NS_AVAILABLE_IOS(3_0); |
假如程序不响应此方法，再实现以下方法：
1 2 3 4 | - (BOOL)canBecomeFirstResponder { return YES; } |
二、motionBegan+通知的方法（建议）
1.在Appdelegate里写motionBegan方法
1 2 3 4 | -(void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event { [[NSNotificationCenter defaultCenter] postNotificationName:@"SAMotionBegan" object:@(motion)]; } |
2.在需要接收通知的页面添加通知
1 2 3 4 5 6 7 8 9 10 | - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [SANotice addObserver:self selector:@selector(shake) name:@"SAMotionBegan" object:nil]; } - (void)shake { SALog(@"摇一摇开始..."); } |
