Hai我找到了解决问题的方法

Hai I have found solution for my problem

解决方案：
对于包含UINavigation控制器的应用程序，我只为UINavigation Controller类创建了一个类别，我定义了这些方法

Solution: For the app which consist UINavigation controller, just I created a category for UINavigation Controller class and I defined these methods

-(BOOL) shouldAutorotate{
    return YES;
}

-(NSUInteger) supportedInterfaceOrientations{

    return UIInterfaceOrientationMaskAll;
}

添加此内容后，我的应用程序支持所有方向。

After adding this, all orientation were supported in my app.

同样，我也为UITabBar Controller做了。这对我来说也是通过为UITabBar Controller创建类别来实现的。

The same, I done for UITabBar Controller also.This too worked for me by creating category for UITabBar Controller.

谢谢。
