ios 橫豎屏的使用

1，在info.plist 檔案中添加

2，ViewController.m中-----------最上層的Controller

@implementation UINavigationController (autorotation)
- (BOOL)shouldAutorotate {
    return NO;//禁止旋轉
}
- (NSUInteger)supportedInterfaceOrientations {
    //需要強制豎屏
    return UIInterfaceOrientationMaskPortrait;
}

@end

3，從ViewController.m 如何跳轉到   需要橫屏的頁面

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

4，需要橫屏的頁面

- (BOOL)shouldAutorotate {
    return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
    //需要強制橫屏
    return UIInterfaceOrientationMaskLandscape;
}

5，返回到 ViewController.m中

[self dismissViewControllerAnimated:YES completion:nil];
