【已解决】iOS11中在某个页面中禁止设备旋转

iOS crifan 670浏览 0评论

之前已经实现了,在报表页面:

但是代码中固定了设备的从竖屏转到横屏,且禁止设备本身的旋转

以便于放置用户旋转手机时,页面显示就旋转了,而不方便看本身只适合在横屏显示的内容

此处写好了的代码,在iOS11之前的设备中,已经是正常工作,可以禁止设备旋转的

但是在iOS11中,还是会出现:

在旋转设备时,屏幕短暂的旋转了一下

从横屏到竖屏后再回到横屏

所以此处要去搞清楚,如何在iOS11中,禁止掉这个切换。

只是代码中设置为横屏,然后禁止掉设备的任何的旋转

ios11 disable device rotate

UIInterfaceOrientationMask – UIKit | Apple Developer Documentation

“Starting in iOS 8, you should employ the UITraitCollection and UITraitEnvironmentAPIs, and size class properties as used in those APIs, instead of using UIInterfaceOrientation constants or otherwise writing your app in terms of interface orientation.”

在iOS8之后,应该用:

UITraitCollection – UIKit | Apple Developer Documentation

UITraitEnvironment – UIKit | Apple Developer Documentation

setOverrideTraitCollection(_:forChildViewController:) – UIViewController | Apple Developer Documentation

UIInterfaceOrientationMask – UIKit | Apple Developer Documentation

ios11 device rotation UITraitCollection UITraitEnvironment

Size classes iPad Portrait/Landscape – If let swift = Programming! – Medium

关于屏幕方向,好像这个类并不合适。

traitCollectionDidChange(_:) – UITraitEnvironment | Apple Developer Documentation

还是用之前的那个UIInterfaceOrientationMask

【总结】

相关代码:

ReportDetailsViewController.swift

import UIKit
class ReportDetailsViewController: UIViewController,UIWebViewDelegate {
    init(url:String,title:String) {
。。。
        super.init(nibName: nil, bundle: nil)
        self.appDelegate.disableRotation = true
        UIDevice.rotateTo(newDirection: DeviceDirectionReportDetail)
    }
    
。。。
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        //Note: move following code to init, otherwise will warning 请用横屏浏览
        // also add same code here to makesure to really take effect
        self.appDelegate.disableRotation = true
        UIDevice.rotateTo(newDirection: DeviceDirectionReportDetail)
        
。。。
    }
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        appDelegate.disableRotation = false
        UIDevice.rotateTo(newDirection: DeviceDirectionAppDefault)
    }
    override var shouldAutorotate : Bool {
        return false
    }
    
    override func willRotate(to toInterfaceOrientation: UIInterfaceOrientation, duration: TimeInterval) {
        appDelegate.disableRotation = true
        UIDevice.rotateTo(newDirection: DeviceDirectionReportDetail)
    }
。。。
    
    override func viewDidLoad() {
        super.viewDidLoad()
。。。
    }
    。。。
}

AppDelegate.swift

let DeviceDirectionAppDefault = UIInterfaceOrientation.portrait
let DeviceDirectionReportDetail = UIInterfaceOrientation.landscapeLeft
let DeviceDirectionMaskAppDefault = UIInterfaceOrientationMask.portrait
let DeviceDirectionMaskReportDetail = UIInterfaceOrientationMask.landscapeLeft
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UINavigationControllerDelegate,JPUSHRegisterDelegate{
    let curVersion = CurVersion()
    
    var disableRotation: Bool = false
    
    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        if self.disableRotation {
//            return UIInterfaceOrientationMask.all
            return DeviceDirectionMaskReportDetail
        } else {
//            return UIInterfaceOrientationMask.portrait
            return DeviceDirectionMaskAppDefault
        }
    }
}

CrifanDevice.swift

import UIKit
extension UIDevice {
    static func rotateTo(newDirection:UIInterfaceOrientation) {
        self.current.setValue(newDirection.rawValue, forKey: "orientation")
    }
}

效果:

旋转之前:

旋转之后:
