推荐答案

您可以使用以下代码在登录ViewController后在第一个屏幕中检查设备方向:-

you can check Device orientation in your first screen after login viewcontroller using bellow code:-

-(void)viewWillAppear:(BOOL)animated
    {
        [self willRotateToOrientation:[[UIDevice currentDevice] orientation]];  
        [super viewWillAppear:YES];
    }


- (void)willRotateToOrientation:(UIInterfaceOrientation)newOrientation {
        if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
        {
            if (newOrientation == UIInterfaceOrientationLandscapeLeft || newOrientation == UIInterfaceOrientationLandscapeRight) {

              //set your landscap View Frame
                [self supportedInterfaceOrientations];

            }



        }
        else if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation))
        {
            if(newOrientation == UIInterfaceOrientationPortrait || newOrientation == UIInterfaceOrientationPortraitUpsideDown){
      //set your Potrait View Frame
                [self supportedInterfaceOrientations];

            }
        }
        // Handle rotation
    }

或者在加载此ViewController时先检查设备排列，然后加载其相关框架

sor when you load this viewcontroller it check first device oriantation and then load it's related frame
