单个页面横屏!

如果有NAVC可能会不好用

你可以复写viewcontroller的下面几个模板函数，试试。

- (BOOL)shouldAutorotate NS_AVAILABLE_IOS(6_0);当前viewcontroller是否支持转屏

- (NSUInteger)supportedInterfaceOrientations；当前viewcontroller支持哪些转屏方向

-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation当前viewcontroller默认的屏幕方向

可以试试这个方法:

if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) {
       
        SEL selector = NSSelectorFromString(@"setOrientation:");
       
        NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]];
       
        [invocation setSelector:selector];
       
        [invocation setTarget:[UIDevice currentDevice]];

       

        int val = UIInterfaceOrientationLandscapeLeft; // 选择屏幕旋转的样式

       
        [invocation setArgument:&val atIndex:2];
       

        [invocation invoke];

    }
