UITabBarController +自动旋转 [英] UITabBarController + autorotation

问题描述

我使用IB创建了一个具有TabBarController的应用程序，该应用程序具有4个TabBarItems，因此显示4个不同的ViewControllers. 为了允许横向放置，我必须在所有ViewController中添加以下代码:

I created an application with a TabBarController using IB who have 4 TabBarItems and so display 4 differents ViewControllers. To allow a landscape orientation I must add this code in all of my ViewController:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
     return (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ? NO : YES);
}

问题是我不希望例如secondViewController自动旋转，我该怎么做? 因为每次我在其中一个ViewController中删除上面的代码时，每个ViewController都不再旋转.

The problem is I don't want for example the secondViewController to autorotate, How can I do that? Because everytime I delete the code above in one of my ViewController, every ViewControllers not rotate anymore.

谢谢

推荐答案

将代码保留在其中，但是您需要执行以下两项操作之一:

Leave the code in there, but you'll want to do one of two things:

1. 显示横向视图时禁用不可旋转的标签，或者
2. 在该标签的viewWillAppear或viewDidAppear中，强制旋转为纵向.

例如:

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES]
