IOS 3.0 + 开始支持motion事件,检测设备摇动 – motionBegan:withEvent: 摇动开始时执行 – motionEnded:withEvent: 摇动结束时执行 – motionCancelled:withEvent: 摇动被取消时执行 具体检测代码如下: 1、 在AppDelegate.m中 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *) launchOptions{ ... application.applicationSupportsShakeToEdit = YES;//添加此处 ... return YES; } 2、在viewController中加入 -(BOOL)canBecomeFirstResponder { return YES; } -(void)viewDidAppear:(BOOL)animated{ [super viewDidAppear:animated]; [self becomeFirstResponder]; } - (void)viewWillDisappear:(BOOL)animated { [self resignFirstResponder]; [super viewWillDisappear:animated]; } - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{ if (motion == UIEventSubtypeMotionShake) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"摇一摇!" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil]; [alert show]; } }
