iOS全局的悬浮窗

1.这个悬浮窗的持有者应该是比较稳定的，一般写在AppDelegate里面，KDEAISellFloatWindow继承于UIWindow， 关于UIWindow，为了保证始终悬浮在最上层，可以给windowLevel 设置成UIWindowLevelAlert
UIWindowLevelAlert > UIWindowLevelStatusBar>UIWindowLevelNormal
等级高的会优先显示覆盖掉等级低的
- (void)initFloatWindow{
CGFloat screenWidth = [UIScreen mainScreen].bounds.size.width;
CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
self.floatWindow = [[KDEAISellFloatWindow alloc] initWithFrame:CGRectMake(screenWidth - KDEAISellFloatWindowWidth, screenHeight - KDEAISellFloatWindowHeight - KDEAISellFloatWindowBottomSpace , KDEAISellFloatWindowWidth, KDEAISellFloatWindowHeight)];
self.floatWindow.hidden = YES;
self.floatWindow.floatType = KDEAISellFloatWindowTypeSupportPortraitPan;
__weak typeof(self) weak_self = self;
self.floatWindow.clickAction = ^{
weak_self.floatWindow.hidden = YES;
[[weak_self getCurrentViewController] presentViewController:[KDEAISellThreeInterviewsManager shareManager].interviewsVC animated:YES completion:^{
}];
};
}
