iOS 使用 UINavigationBar 和 UIStatusBar 缩放 UIView

Question

我需要实现滚动视图，它包含几个带有 UINavigationBar 和 UIStatusBar 的缩放子视图。

如何获取 UIStatusBar 以在缩放视图上显示它？因为现在我实现了这个（显示在左边——没有状态栏的缩放视图）但我需要这个（显示在右边）：

UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
//get view controller and navigation controller from storyboard
UINavigationController *mainNavigControll = [sb instantiateViewControllerWithIdentifier:@"mainNavigControll"];
UIViewController *myViewObject = [sb instantiateViewControllerWithIdentifier:@"myViewController"];

//scaled view and all sub view
CGAffineTransform transform = CGAffineTransformMakeScale(scale, scale);
for( UIView* v in myViewObject.view.subviews )
    v.transform = transform;
[myViewObject.view addSubview:myViewObject.navigationController.view];
myViewObject.view.transform = transform;

//get navigation bar and set navigation item
UINavigationBar * navig_bar = mainNavigControll.navigationBar;
[navig_bar pushNavigationItem:myViewObject.navigationItem animated:NO];
//add navigation bar to view
[myViewObject.view addSubview:navig_bar];

//TODO: need added UIStatusBar ????
...

//add to scroll view
[_scrollView addSubview:myViewObject.view ];

这个滚动视图必须看起来像 iOS 7 上的多任务处理，但只有一些内部视图。

在您拥有的自定义视图控制器中使用[[UIApplication sharedApplication] setStatusBarHidden:NO];。
