在 UIView 过渡、翻转或翻转时点击按钮

Question

我儿子刚刚发现他可以点击我视图的“完成”按钮，该按钮会翻转到上一个视图，一次开始翻转，一次或多次在视图转换（翻转）时。第二次和下一次点击将再次触发相同的操作，产生一些有趣的结果，例如最终没有可见的视图，但我的底层 UIWindow。

我想我应该打电话给：

[coming.view setUserInteractionEnabled: NO];
[going.view setUserInteractionEnabled: NO];

在翻转过渡中涉及的两个视图上，然后

[coming.view setUserInteractionEnabled: YES];

动画结束后的最终视图。

我在想也许比这更好的方法是在任何视图转换时全局禁用水龙头。你怎么看？

下面是整个视图切换代码：

- (void)switchTwoViews:(UIViewController *)view1 otherView:(UIViewController *)view2
{
    /*
     This method is called to switch views.
     It flips the displayed view from the main view to the flipside view and vice-versa.
     */

    UIViewController *coming = nil;
    UIViewController *going = nil;
    UIViewAnimationTransition transition;

    [view1.view setUserInteractionEnabled: NO];
    [view2.view setUserInteractionEnabled: NO];
    if (view1.view.superview == nil) {
        coming = view1;
        going = view2;
        transition = UIViewAnimationTransitionFlipFromLeft;
    }
    else {
        coming = view2;
        going = view1;
        transition = UIViewAnimationTransitionFlipFromRight;
    }
    //  coming.view.frame = [UIScreen mainScreen].applicationFrame;

    //  going.view.alpha = 1.0;     //uncomment these lines if we want fading of views
    //  coming.view.alpha = 0.0;

    NSArray *viewArray = [[NSArray alloc] initWithObjects:coming, going, nil];
    [coming viewWillAppear:YES];
    [going viewWillDisappear:YES];
    [UIView beginAnimations:@"View Flip" context:viewArray]; {
        [UIView setAnimationDuration:1.0];
        [UIView setAnimationDelegate:self];
        [UIView setAnimationDidStopSelector:@selector(animationDidEnd:finished:context:)];
        [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

        //      coming.view.alpha = 1.0;        //uncomment these lines if we want fading of views
        //      going.view.alpha = 0.0;

        [UIView setAnimationTransition:transition forView:self.view cache:YES];
        [self.view addSubview: coming.view];
    }
    [UIView commitAnimations];

}

- (void) animationDidEnd:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{
    NSArray *viewArray = context;
    [((UIViewController *)[viewArray objectAtIndex:1]).view removeFromSuperview];
    [[viewArray objectAtIndex:1] viewDidDisappear:YES];
    [[viewArray objectAtIndex:0] viewDidAppear:YES];
    [[[viewArray objectAtIndex:0] view] setUserInteractionEnabled: YES];
    [viewArray release];
}

setUserInteractionEnabled：似乎是要走的路。有异议吗？
