1.悬浮球与设备刘海的安全距离
无论是横屏还是竖屏，悬浮球距离有刘海的一边会留出安全距离
设备方向的上下两边，也有安全距离

2.贴边吸附方向和距离
悬浮球只能贴设备方向的左右两边，需要贴上下两边自行调整
距离边缘的数值自行调整

3.切换横竖屏，悬浮球自适应
悬浮球位置切换横竖屏后，等比例转换的。

4.隐藏和显示
拖到屏幕中间ImageView范围内可以隐藏悬浮窗，在范围内会由蓝色变红色，可自定义图片或者大小

使用说明：

悬浮球点击事件代理方法
- (void)suspendViewButtonClick:(UIButton*)sender;
悬浮球在ImageView范围内提示是否隐藏悬浮窗
- (void)showHideAlertView;
显示悬浮窗
- (void)showSuspendView;
隐藏悬浮窗
- (void)dismissSuspendView;
