在ios5下画面的旋转都是shouldAutorotateToInterfaceOrientation来控制的,但是这个函数在ios6下不起作用。
在ios6下使用supportedInterfaceOrientations、shouldAutorotate来控制。
如果单一的控制画面那么只需要加在上面两个函数。如下
- (BOOL)shouldAutorotate { return YES; } - (NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskAll; }
如果是含有UINavigationController、UITabBarController的话,那么修改部分就多了。
用其派生类的,在派生类中增加上面的supportedInterfaceOrientations、shouldAutorotate函数。
下面如MyNavigationController就是UINavigationController 的派生类。
修改部分如下
1:在旧的程序中AppDelegate的部分如
定义的 UINavigationController *navigationController;
[window addSubview:[navigationController view]]; //不能旋转改为
MyNavigationController *myNavigationController;
self.window.rootViewController = self.myNavigationController;
派生类主要部分为
#import "MyNavigationController.h" @interface MyNavigationController () @end @implementation MyNavigationController - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. } -(BOOL)shouldAutorotate { return [self.viewControllers.lastObject shouldAutorotate]; } -(NSUInteger)supportedInterfaceOrientations { return [self.viewControllers.lastObject supportedInterfaceOrientations]; } -(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { return [self.viewControllers.lastObject preferredInterfaceOrientationForPresentation]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end
根据多篇文章改写的,目前根据这样的方式,能够解决自己目前的问题,
如果大家还有更好的方式,还需要多指教。
