How to force a screen orientation in specific view controllers?

你好

我想在一个特定的视图中设置方向，那么我该怎么做。和body有例子。我用了

-(void)onUIDeviceOrientationDidChangeNotification:(NSNotification*)notification{
    UIViewController *tvc = self.navigationController.topViewController;
    UIDeviceOrientation orientation = [[ UIDevice currentDevice ] orientation ];
    tabBarController.view.hidden = YES;
    // only switch if we need to (seem to get multiple notifications on device)
    if( orientation != [[ UIApplication sharedApplication ] statusBarOrientation ] ){
        if( [ tvc shouldAutorotateToInterfaceOrientation: orientation ] ){
            [ self rotateInterfaceToOrientation: orientation ];
        }
    }
}

但它完成的是整个应用程序，我只想在一个屏幕上完成，所以请回复谢谢

你想为你的应用应用单一方向吗？？？

【解决方案1】：

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    // Over ride this method in your required view controller to display only in the necessary orientation
}

【解决方案2】：

在你的类中添加这个方法

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    // Over ride this method in your required view controller to display only in the necessary orientation
     return YES;
}

【解决方案3】：

在一个特定的视图控制器上放

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

这是为其他你可以明智地做的肖像画
