iOS 关于调整状态栏方向方法setStatusBarOrientation的使用注意事项

通过

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:YES];

方法的枚举可以设置状态栏方向，但是需要在viewController中重写

- (BOOL)shouldAutorotate

{

    return NO;

}

返回值为NO

如果此viewController在某个 UINavigationController中需要在AppDelegate中写个类目

@implementation UINavigationController (Rotation)

- (BOOL)shouldAutorotate

{

//在viewControllers中返回需要改变的viewController

    return [[self.viewControllers firstObject] shouldAutorotate];

}

@end

如果此 UINavigationController在某个 UITabBarController中需要在AppDelegate中再写个类目

@implementation UITabBarController (Rotation)

- (BOOL)shouldAutorotate

{

//在viewControllers中返回需要改变的NavigationController

    return [[self.viewControllers firstObject] shouldAutorotate];

}

@end
