iOS 监听StatusBar点击事件

当使用到的视图继承UIScrollView,并且frame为当前视图的bounds, scrollsToTop = true,以上情况下点击状态栏会使得滚动视图回滚到顶部.
在其他情况下又想知道获取当前的点击事件:

private typealias TouchStatusAction = AppDelegate
extension TouchStatusAction {
    override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
        super.touchesEnded(touches, withEvent: event)
        let touchLocation = event!.allTouches()?.first!.locationInView(self.window)
        let statusBarFrame = UIApplication.sharedApplication().statusBarFrame
        if (CGRectContainsPoint(statusBarFrame, touchLocation!))
        {
            self.statusBarTouchedAction()
        }

    }
    func statusBarTouchedAction() {
        NSNotificationCenter.defaultCenter().postNotificationName("statusBarNotification", object: nil)
    }
}

在使用的地方监听

NSNotificationCenter.defaultCenter().addObserver(self, selector: "clickAction", name:"statusBarNotification", object: nil)

OK,完成!
