iphone - setStatusBarOrientation 不起作用

Question

我正在尝试将状态栏的方向修复为纵向，但没有成功。我努力了：

[application setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO]; 

并且还shouldAutorotateToInterfaceOrientation设置为 return NO。

请帮帮我。

Answer 1

If you want to change the orientation when a particular view is showing, you should call [UIApplication setStatusBarOrientation:animated:] inside your [UIViewController viewWillAppear:] override method for each of the view controllers that force a particular orientation. That will cause a change when a view is being pushed onto the stack and when it's being popped off it. Make sure you call super in your override method.

Also change your shouldAutorotateToInterfaceOrientation method:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
   return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
