IOS 檢測搖動

 

有兩種方式檢測搖動：

1. 繼承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];//訊息註冊    }}- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{    }

 

2. 在AppDelegate.m中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    ...    application.applicationSupportsShakeToEdit = YES;//添加此處    ...    return YES;}

然後在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(@"搖啊搖");    }}
