问题描述

我正在开发app。应用程序的方向是横向，但在app运行app界面方向后更改界面并旋转。以正确的方式（横向）启动屏幕显示。
我正在使用ios7应用程序是ios5的代码我认为有一些弃用的api问题，例如shouldAutorotateToInterfaceOrientation bot被调用因为在最新的ios中不再可用

推荐答案

如果您希望我们的所有导航控制器都尊重顶视图控制器，您可以使用类别，所以你不必经历并改变一堆类名。

If you want all of our navigation controllers to respect the top view controller you can use a category so you don't have to go through and change a bunch of class names.

 @implementation UINavigationController (Rotation_IOS6)

-(BOOL)shouldAutorotate
{
   return [[self.viewControllers lastObject] shouldAutorotate];
 } 

-(NSUInteger)supportedInterfaceOrientations
{
    return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [[self.viewControllers lastObject]     preferredInterfaceOrientationForPresentation];
}

@end

作为一些评论指出，这是对问题的快速解决方法。更好的解决方案是子类UINavigationController并将这些方法放在那里。子类也有助于支持6和7。

As a few of the comments point to, this is a quick fix to the problem. A better solution is subclass UINavigationController and put these methods there. A subclass also helps for supporting 6 and 7.
