iOS微信摇一摇

//微信的摇一摇是怎么实现的~发现原来 ios本身就支持
//在 UIResponder中存在这么一套方法

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);

- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);

//这就是执行摇一摇的方法。那么怎么用这些方法呢？
//很简单，你只需要让这个Controller本身支持摇动
//同时让他成为第一相应者：

- (void)viewDidLoad{
    [superviewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
    [[UIApplicationsharedApplication] setApplicationSupportsShakeToEdit:YES];
    [selfbecomeFirstResponder];
}

//然后去实现那几个方法就可以了

- (void) motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event{
    //检测到摇动
}

- (void) motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{
    //摇动取消
}

- (void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{
    //摇动结束
    if (event.subtype == UIEventSubtypeMotionShake) {
        //something happens
    }
}
