ios 7文档交互控制器隐藏状态栏

Question

在我的iOS应用程序中，我在每个ViewController中隐藏了带有此代码的状态栏：

- (BOOL)prefersStatusBarHidden
{
    return YES;
}

在视图中我需要使用UIDocumentInteractionController，但是当它出现时，会出现状态栏，有没有办法让它隐藏？

提前致谢

Answer 1

使用以下代码和iOS代码的组合：

- (UIViewController *) documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *) controller {
  // hack to keep status bar visible
  [[NSOperationQueue mainQueue] addOperationWithBlock:
    ^{
      [[UIApplication sharedApplication] setStatusBarHidden:NO];
  }];
  return self;
}

结合

- (void)documentInteractionControllerDidEndPreview:(UIDocumentInteractionController *)controller {
  [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

Answer 2

试试这个对我有用：

- (void)documentInteractionControllerWillBeginPreview:(UIDocumentInteractionController *)controller
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

- (void)documentInteractionControllerDidEndPreview:(UIDocumentInteractionController *)controller
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

将documentController.delegate设为自己并使用

- (void)documentInteractionControllerDidEndPreview:(UIDocumentInteractionController *)controller {
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}
