IOS 检测摇动

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");}
}
