轻松且线程/内存安全地消费全局 OS X 多点触摸（触摸板、Magic Mouse）事件。
注意：需要 ARC，且 Mac OS 10.8+。

}];注意：多点触控事件处理在一个单独的线程上完成，但您的监听器将在它被创建的线程上传递事件（或者在原始线程停止时是主线程）。
[M5MultitouchManager.sharedManager addListenerWithTarget:self
selector:@selector(handleMultitouchEvent:)];- (void)handleMultitouchEvent:(M5MultitouchEvent *)event {
NSLog(event.description);
}注意：仅保持对目标的弱引用，如果该引用为零，则 M5MultitouchManager 会安全地删除监听器。
M5MultitouchListener *listener = [M5MultitouchManager.sharedManager addListenerWith...
listener.listening = NO;
//Listener will stop receiving events until set to YES
[M5MultitouchManager.sharedManager removeListener:listener];
//Will stop/remove the listener altogether如果您有功能请求或错误报告，请通过发送拉取请求或在 创建新问题 的方式来帮助。
