Ios Xcode、UISweepGestureRecognitor、ViewController转换方式是否错误？

我使用最新的Xcode。因此，我将SwipGestureRecognizer放在我的ViewController中，并通过SHOW（push）序列将其连接到另一个ViewController。根据属性检查器，我可以选择左/右。但是，当我构建/运行project并向左/向右滑动以在视图控制器之间转换时，转换是向上/向下的，而不是向右/向左的

如何进行右/左滑动使VC向右/向左移动，而不是向上/向下移动？

对于swift 3.0

let transition = CATransition()
transition.duration = 0.5
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
view.window!.layer.add(transition, forKey: kCATransition)
present(dashboardWorkout, animated: false, completion: nil)

目标c

CATransition *transition = [[CATransition alloc] init];
transition.duration = 0.5;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.window.layer addAnimation:transition forKey:kCATransition];
[self presentViewController:dashboardWorkout animated:false completion:nil];
