Question

我刚刚切换到iOS7 SDK。我的应用程序在此之前在iOS6上运行良好，但现在没有了，除了它现在在iOS7上正常工作。

我有一个带页面控件的scrollView，可以显示3个不同的选项卡，其中包含以下设置：

self.scrollView.pagingEnabled = YES;
self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * 3, self.scrollView.frame.size.height);
self.scrollView.showsHorizontalScrollIndicator = NO;
self.scrollView.showsVerticalScrollIndicator = NO;
self.scrollView.scrollsToTop = NO;
self.scrollView.delegate = self;

我添加了这个scrollView我的3个视图，我从3个不同的故事板加载：

    UIStoryboard *timelineStoryboard=[UIStoryboard storyboardWithName:@"timelineStoryboard" bundle:nil];
TabBarViewController *mainVC=[timelineStoryboard instantiateInitialViewController];
self.currentViewController =mainVC;
[mainVC.view setFrame:CGRectMake(320, 20, mainVC.view.frame.size.width, mainVC.view.frame.size.height)];
[self.scrollView addSubview:mainVC.view];
[self addChildViewController:mainVC]; 

UIStoryboard *expenseStoryboard=[UIStoryboard storyboardWithName:@"expenseStoryboard" bundle:nil];
TabBarViewController *leftVC=[expenseStoryboard instantiateInitialViewController];
self.leftViewController =leftVC;
[leftVC.view setFrame:CGRectMake(0, 20, leftVC.view.frame.size.width, leftVC.view.frame.size.height)];
[self.leftViewController.view setFrame:CGRectMake(0, 20, leftVC.view.frame.size.width, leftVC.view.frame.size.height)];
[self.scrollView addSubview:leftVC.view];
[self addChildViewController:leftVC];


UIStoryboard *dashboardStoryboard=[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
TabBarViewController *rightVC=[dashboardStoryboard instantiateViewControllerWithIdentifier:@"dashboardVC"];
self.leftViewController =rightVC;
[rightVC.view setFrame:CGRectMake(640, 20, rightVC.view.frame.size.width, rightVC.view.frame.size.height)];
[self.scrollView addSubview:rightVC.view];
[self addChildViewController:rightVC];

在iOS6上，这3个视图显示在彼此之上，而在iOS7上它们被正确显示（在横坐标为0时，一个在x = 320处，另一个在x = 640处）。有没有人知道如何解决这个问题？

非常感谢

我找到了答案。我使用了中间变量，它起作用了。不过不知道为什么。如果有人有答案，我很高兴听到它。

无论如何，有效的代码在这里：

UIStoryboard *dashboardStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
TabBarViewController  *rightVC = [dashboardStoryboard instantiateViewControllerWithIdentifier:@"dashboardVC"];

UIView *dashboardView = rightVC.view;
[dashboardView setFrame:CGRectMake(640,
                                   20,
                                   320,
                                   screenHeight+20)];

[self.scrollView addSubview:dashboardView];
[self addChildViewController:rightVC];

在iOS7上工作的setFrame，但在iOS6上不再存在
