轮换后整个视图从右侧移动

Question

我的主屏幕如下图所示。我使用了Storyboards和size类来设计屏幕，这里的屏幕集合视图用于显示数据。

如果我使用导航控制器导航到任何屏幕，旋转上面的主屏幕后，整个视图将从右侧移动（使用下面屏幕截图中的红线显示的区域）。只有当我旋转第一个屏幕时才会发生这种情况，否则一切都会好的，而且我没有在＆＃34; viewWillTransitionToSize＆＃34;主屏幕的事件（第一次截图）。

我使用＆＃34; NSLog＆＃34;检查了第二个屏幕的高度和宽度。在＆＃34; ViewDidLoad＆＃34;方法，它是正确的。但为什么屏幕会从右侧移开？

我已使用以下代码在主屏幕（屏幕1）中使用UICollectionView加载数据。

   -(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
    return 1;
}

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {   
    return  arrDashBoardList.count;
}


- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView1 cellForItemAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *identifier = @"Cell";
    //static float fltAlpha =1.0f;

    UICollectionViewCell *cell = [collectionView1 dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];

    UILabel *lblIcon = (UILabel *)[cell viewWithTag:100];
    lblIcon.font = [UIFont fontWithName:chsIcons size:160];
    lblIcon.textColor = [UIColor colorWithRed:65.0f/255.0f green:168.0f/255.0f blue:119.0f/255.0f alpha:1.0f];
    lblIcon.text =[arrDashBoardImages objectAtIndex:indexPath.row];

    UILabel *lblModule = (UILabel *)[cell viewWithTag:101];
    lblModule.text = [arrDashBoardList objectAtIndex:indexPath.row];
    lblModule.font =[UIFont fontWithName:KlavikaRegular size:25];
    lblModule.textAlignment = NSTextAlignmentCenter;
    lblModule.textColor = [UIColor blackColor];

    return cell;
}

- (void)collectionView:(UICollectionView *)collectionView1 didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
    UIStoryboard* storyboard = [UIStoryboard storyboardWithName:STORYBOARD_MAIN bundle:nil];
    NavigationViewController_iPhone *navigationController = [storyboard instantiateViewControllerWithIdentifier:@"contentController"];

    if([[arrDashBoardList objectAtIndex:indexPath.row] caseInsensitiveCompare:@“abc”] == NSOrderedSame) //Events
    {
        UIStoryboard* storyboard = [UIStoryboard storyboardWithName:STORYBOARD_DASHBOARD bundle:nil];
        ABCViewController_iPad *controller = [storyboard instantiateViewControllerWithIdentifier:@"abcController"];
        navigationController.viewControllers = @[controller];
    }
    else if([[arrDashBoardList objectAtIndex:indexPath.row] caseInsensitiveCompare:@“xyz”] == NSOrderedSame)//Active Floats
    {
        UIStoryboard* storyboard = [UIStoryboard storyboardWithName:STORYBOARD_DASHBOARD bundle:nil];
        XYZViewController_iPad  *controller = [storyboard instantiateViewControllerWithIdentifier:@“xyzController"];
        navigationController.viewControllers = @[controller];
    }

    self.frostedViewController.contentViewController = navigationController;
}

我看起来像collectionView没有填充其父级，所以你需要找到它的父级的高度和宽度，并为这个布局设置这些值，

[UIScreen mainScreen].bounds.size.width

知道屏幕的大小，只需将UICollectionView的框架设置为刚刚想出的宽度。
