iOS 7 - 仅在一个视图控制器中限制横向方向 [英] iOS 7 - Restrict landscape orientation only in one view controller

问题描述

我只需要在纵向模式下打开第一个视图控制器。由于其余视图控制器将使用两个方向。所以我在plist文件中添加了两个方向。

I need to open the first view controller only in portrait mode. As the rest view controllers will use both orientation. So i have added both orientation in plist file.

-(BOOL) shouldAutorotate {
    //Never called
}

- (NSUInteger) supportedInterfaceOrientations {
    //Never called
}

任何人都可以告诉我如何限制

can any one tell me how to restrict

推荐答案

通过创建UINavigationController类来修复它覆盖

Fixed it simply by creating UINavigationController class and overriding

-(NSUInteger)supportedInterfaceOrientations
{
    AppDelegate *appDelegate = (AppDelegate *) [UIApplication sharedApplication].delegate;
    if(appDelegate.isOrientationOn) {
        return UIInterfaceOrientationMaskAll;
    }
    return UIInterfaceOrientationMaskPortrait;
}

在根窗口中使用此自定义导航控制器类，这就是全部。

Use this custom navigation controller class in root window and that's all.
