ios晃动检测

 

ios晃动检测 

第一种

1、在AppDelegate.h中进行如下设置：

 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    application.applicationSupportsShakeToEdit = YES;
}

 

2、在你需要对晃动事件进行处理的ViewController中添加如下代码：

 

-(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(@"检测到晃动");
    }
