仅在ios swift 2.3和swift 3中更改特定视图控制器的方向 [英] Change the orientation only for specific view controllers in ios swift 2.3 and swift 3

问题描述

我是searching，当项目settings中的Device Orientation设置为Portrait时，如何仅将spefic view controller的orientation更改为LandScape模式.没有获得任何成功的结果.所以最后我找到了一种方法.

I was searching that how can I change the orientation to LandScape mode only for spefic view controller when the Device Orientation is set to Portrait in the project settings. Didn't get any succesfull result. so finally I found a way to do it.

这是项目设备方向，看起来像....

this is project device orientation looks like ....

在Swift 2.3中添加以下方法

override func shouldAutorotate() -> Bool {
        return false
    }

    override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        return UIInterfaceOrientationMask.LandscapeLeft
    }


    override func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation {
        return UIInterfaceOrientation.LandscapeLeft
    }

对于Swift 3.0，请执行以下操作....

  override var shouldAutorotate: Bool {
        return false
    }

    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return .landscapeLeft
    }

    override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
        return .landscapeLeft
    }

注意:如果您在没有导航控制器的情况下从一个视图导航到另一个视图控制器，这将很好地工作.

推荐答案

使用 supportedInterfaceOrientationsFor 应用程序委托.在 AppDelegate 文件中添加以下代码

Use supportedInterfaceOrientationsFor application delegate.add following code in AppDelegate file

 func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {

            if isIpadLandscape {
                 return UIInterfaceOrientationMask.all;
            }else{
                return UIInterfaceOrientationMask.portrait;

            }


    }


Add particular **viewcontroller** page you want to **rotate**

     override func viewDidLoad() {
            super.viewDidLoad()
            isLandscape = true
    }
    override func viewWillDisappear(_ animated: Bool) {
            isLandscape = false
        }

别忘了在appdelegate文件中添加全局变量

And dont forget to add global varibale in appdelegate file

import UIKit
import CoreData
import Foundation
    var isLandscape = false
    @UIApplicationMain
