.M關鍵代碼文件如下

#pragma mark 解決適配iOS 8.x 系統橫屏問題
-(void)viewDidLayoutSubviews{

    }else if (interfaceOrientation==UIDeviceOrientationLandscapeLeft || interfaceOrientation == UIDeviceOrientationLandscapeRight) {
        //翻轉為橫屏時
        [self setHorizontalFrame];
    }
}
//這里的frame size根據值項目中的大小來自定義
-(void)setVerticalFrame

    ///豎屏 
    self.viewFrame = CGRectMake(0, 64,ScreenWidth ,ScreenHeight-64);
}
-(void)setHorizontalFrame
{
    ///橫屏
    self.viewFrame = CGRectMake(0, 32,ScreenWidth , ScreenWidth-320);
}
