transitionFromView 和索引

我正在使用一个控制器（MAIN）来管理如何在其主视图中呈现另外 2 个控制器（A 和 B）视图。在主控制器视图中，我在主视图 xib 中创建了一个按钮。 BUTTON 必须位于 A 和 B 视图之上。

所以这就是我需要的视图层次结构：

MAIN.VIEW
      |------A or B view (index 0)
      |------BUTTON      (index 1)

这里我如何将 A 和 B 创建到 MAIN 中：

//MAIN CONTROLLER viewDidLoad
- (void)viewDidLoad {
    [super viewDidLoad];

    self.A = [[A alloc] init];
    self.B = [[B alloc] init];

    //Start from A view visible in MAIN
    [self.view insertSubview:self.A.view atIndex:0]; 
}

在特定操作调用之后，我想插入控制器 B 视图并删除 A。我读到有关transitionFromView的内容，我尝试以这种方式使用它：

[UIView transitionFromView:self.A.view
                    toView:self.B.view
                  duration:1.0
                   options:UIViewAnimationOptionTransitionFlipFromRight
                completion:^(BOOL finished) {
                    if (finished) {
                        //nothing for now...
                    }
                }];

这里的问题是，翻转动画后B视图位于BUTTON之上，并且没有完全占据我的层次结构中A的位置（A位于索引0）

我可以添加这个代码进入完成块：

[self.view sendSubviewToBack:self.B.view];

但我认为这是一个有点棘手的解决方案：P（而且这也不是一个好的解决方案，因为它似乎在动画结束时有效地出现，但图形效果很差......）

这是最好的方法确保 A 和 B 是放置在索引 0 ?

原文

I'm working with a controller (MAIN) that manage how presents 2 other controllers (A and B) views in its main view.
In MAIN controller View i have a BUTTON created into the MAIN view xib.
BUTTON must be over A and B view.

So this's the view hierarchy structure i need :

MAIN.VIEW
      |------A or B view (index 0)
      |------BUTTON      (index 1)

Here how i create A and B into MAIN:

//MAIN CONTROLLER viewDidLoad
- (void)viewDidLoad {
    [super viewDidLoad];

    self.A = [[A alloc] init];
    self.B = [[B alloc] init];

    //Start from A view visible in MAIN
    [self.view insertSubview:self.A.view atIndex:0]; 
}

After a specific action call i want to insert controller B view and remove A.
I read about transitionFromView and i tried to use it this way:

[UIView transitionFromView:self.A.view
                    toView:self.B.view
                  duration:1.0
                   options:UIViewAnimationOptionTransitionFlipFromRight
                completion:^(BOOL finished) {
                    if (finished) {
                        //nothing for now...
                    }
                }];

The problem here is that after flip animation B view is over BUTTON and doesn't take exactly the place of A in my hierarchy (A was at index 0)

I can add this code into completion Block :

[self.view sendSubviewToBack:self.B.view];

But i think it's a little tricky solution :P (and it's not a good solution too, because it seems appear effectively at the end of the animation with a bad graphic effect...)

Which is the best way to be sure that A and B are placed at index 0 ?
