Ios 如何使用CGAffineTransformMakeScale设置视图及其导航栏的动画 我试图在屏幕中间呈现另一个容器时激活我的容器视图。但我不明白。如果仅对视图设置动画，导航栏将不会执行任何操作，如果我同时对这两个视图设置动画，导航栏将移动

这是我的密码

 let datePickerController = self.storyboard!.instantiateViewControllerWithIdentifier("DatePickerViewController") as! DatePickerViewController
    let navController = UINavigationController(rootViewController: datePickerController)
    navController.modalPresentationStyle = UIModalPresentationStyle.Custom
    navController.transitioningDelegate = self

    UIView.animateWithDuration(0.3, delay: 0.0, options: UIViewAnimationOptions.CurveEaseInOut, animations: {
        self.view.alpha = 0.5
        self.navigationController!.navigationBar.alpha = 0.5
        self.view.transform = CGAffineTransformMakeScale(0.9, 0.9)
        //NavigationBar animattion
       // self.navigationController!.navigationBar.transform = CGAffineTransformMakeScale(0.9, 0.9)
        self.presentViewController(navController, animated:true, completion: nil)
    }) { (Bool) in

    }

我解决了，解决办法就是改变这条线

    self.view.alpha = 0.5
    self.navigationController!.navigationBar.alpha = 0.5
    self.view.transform = CGAffineTransformMakeScale(0.9, 0.9)
    //NavigationBar animattion
   // self.navigationController!.navigationBar.transform = CGAffineTransformMakeScale(0.9, 0.9)

通过这些

  self.navigationController!.view.transform = CGAffineTransformMakeScale(0.93, 0.93)
  self.navigationController!.view.alpha = 0.5
