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:^{
            
        }];
    };
}

    2.继承UIWindow

typedef NS_OPTIONS(NSUInteger, KDEAISellFloatWindowType) {
    KDEAISellFloatWindowTypeNormal = 1 << 0,//仅悬浮
    KDEAISellFloatWindowTypeSupportPortraitPan = 1 << 1,//支持竖屏滑动
    KDEAISellFloatWindowTypeSupportLandscapePan = 1 << 2,//支持横屏滑动
    KDEAISellFloatWindowTypeSupportPortraitSpringToBounds = 1 << 3, //支持竖屏弹至边框
