IOS 检测摇动
有两种方式检测摇动:
1. 继承UIWindow
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event { }- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {if (motion == UIEventSubtypeMotionShake ){// User was shaking the device. Post a notification named "shake".[[NSNotificationCenter defaultCenter] postNotificationName:@"shake" object:self];//消息注册} }- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event { }
2. 在AppDelegate.m中
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {...application.applicationSupportsShakeToEdit = YES;//添加此处 ...return YES; }
然后在viewcontroller中
-(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){NSLog(@"摇啊摇");} }
