ios 横竖屏的使用

1，在info.plist 文件中添加

2，ViewController.m中-----------最上层的Controller

@implementation UINavigationController (autorotation)
- (BOOL)shouldAutorotate {
    return NO;//禁止旋转
}
- (NSUInteger)supportedInterfaceOrientations {
    //需要强制竖屏
    return UIInterfaceOrientationMaskPortrait;
}

@end

3，从ViewController.m 如何跳转到   需要横屏的页面

[self presentViewController:[[VEShareViewController alloc] init] animated:YES completion:nil];

4，需要横屏的页面

- (BOOL)shouldAutorotate {
    return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
    //需要强制横屏
    return UIInterfaceOrientationMaskLandscape;
}

5，返回到 ViewController.m中

[self dismissViewControllerAnimated:YES completion:nil];
