如何使应用程序在iOS 6中完全正常工作以进行自动旋转？

Question

在iOS6中,shouldAutorotateToInterfaceOrientation已弃用.我尝试使用 supportedInterfaceOrientations和shouldAutorotate 使应用程序正常工作自动旋转但失败了.

这个ViewController我不想旋转,但它不起作用.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

有任何想法吗？在此先感谢您的帮助!

Answer 1

弄清楚了.

1)子类化UINavigationController(层次结构的顶层视图控制器将控制方向.)确实将其设置为self.window.rootViewController.

- (BOOL)shouldAutorotate
{
    return self.topViewController.shouldAutorotate;
}
- (NSUInteger)supportedInterfaceOrientations
{
    return self.topViewController.supportedInterfaceOrientations;
}

2)如果您不希望视图控制器旋转

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

3)如果你想让它能够旋转

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

-(BOOL)shouldAutorotate
{
    return YES;
}

BTW,根据您的需要,另一种相关方法:

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
     return UIInterfaceOrientationMaskPortrait;
}
