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;
