iOS 7：如何仅允许VC的纵向方向 [英] iOS 7: How to allow only portrait orientation for VC

问题描述

我的所有项目都允许以横向/纵向模式查看应用程序，但对于一个View Controller，我想禁用此功能并仅以纵向显示它。

All my project allow to view app in landscape/portrait mode, but for one View Controller I want to disable this function and show it only in portrait orientation.

我试过 shouldAutorotate 和 supportedInterfaceOrientations ，但它不起作用。

I have tried shouldAutorotate and supportedInterfaceOrientations, but it don't work.

推荐答案

如果您想要视图控制器的不同方向，请在 AppDelegate 中添加此方法 -

If you want different orientation for view controllers, In AppDelegate add this method -

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
    NSUInteger orientations = UIInterfaceOrientationMaskAllButUpsideDown;

    if(self.window.rootViewController){
        UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
        orientations = [presentedViewController supportedInterfaceOrientations];
    }

    return orientations;
}

和你的ViewController -

and in your ViewController -

-(BOOL)shouldAutorotate{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations{
    return (UIInterfaceOrientationMaskAll);//Change this according to your need
}

希望这会有所帮助。
