swift ios 9 app不在“设置”中

Question

我有快速的相机代码，适用于ios 8和xcode 6。 我调用了AVCaptureDevice.authorizationStatusForMediaType（AVMediaTypeVideo），但我的应用程序没有显示在Settings -> privacy -> Camera中 （但其他应用程序显示）

更新到ios 9和xcode 7后无法获得相机权限。 我在google和stackoverflow上搜索了2天。

问题

我导入了AVFoundation并调用了AVCaptureDevice.authorizationStatusForMediaType（AVMediaTypeVideo），总是得到AVAuthorizationStatus.Denied

1. 我的应用程序未显示在“设置”中 - ＆gt;隐私 - ＆gt;相机
2. 相机是黑色的
3. requestAccessForMediaType无法打开弹出窗口
4. authorizationStatusForMediaType始终被拒绝

主要问题是否1.我想如果我可以在设置上获取我的应用程序 - ＆gt;隐私 - ＆gt;相机然后解决其他问题。

我试过了

• UIImagePickerController的子类
• 删除并重新安装了我的应用
• 更改了套件ID
• 将iphone日期更改为3天
• 在主线程中调用requestAccessForMediaType
• Xcode 7
• ios 9.0 9.1
• iphone 5,5s，6
• swift 2.1

我的代码

override func viewDidLoad() {
    super.viewDidLoad()
        cameraView()
}

func checkCamera() {
        let authStatus = AVCaptureDevice.authorizationStatusForMediaType(AVMediaTypeVideo)
        switch authStatus {
        case AVAuthorizationStatus.Authorized:
            print("AVAuthorizationStatus.Authorized")
        case AVAuthorizationStatus.Denied:
            print("AVAuthorizationStatus.Denied")
        case AVAuthorizationStatus.NotDetermined:
            print("AVAuthorizationStatus.NotDetermined")
        case AVAuthorizationStatus.Restricted:
            print("AVAuthorizationStatus.Restricted")
        default:
            print("AVAuthorizationStatus.Default")
        }

    }

func cameraView(){
        // session
        let mySession : AVCaptureSession = AVCaptureSession()
        var myDevice : AVCaptureDevice? //= AVCaptureDevice()
        let myImageOutput : AVCaptureStillImageOutput = AVCaptureStillImageOutput()
        let devices = AVCaptureDevice.devices()

        let audioCaptureDevice = AVCaptureDevice.devicesWithMediaType(AVMediaTypeAudio)
        let audioInput = (try! AVCaptureDeviceInput(device: audioCaptureDevice[0] as! AVCaptureDevice))  as AVCaptureInput

        for device in devices {
            if(device.position == AVCaptureDevicePosition.Back){
                myDevice = device as? AVCaptureDevice
            }
        }

        let status = AVCaptureDevice.authorizationStatusForMediaType(AVMediaTypeVideo)
        print(status ==  AVAuthorizationStatus.Authorized)
        print(status ==  AVAuthorizationStatus.Denied)
        print(status ==  AVAuthorizationStatus.Restricted)
        print(status.rawValue)

        if status !=  AVAuthorizationStatus.Authorized {

            AVCaptureDevice.requestAccessForMediaType(AVMediaTypeVideo, completionHandler: { (granted :Bool) -> Void in
                if granted == false {
                    // Camera not Authorized
                    dispatch_async(dispatch_get_main_queue()) {
                        print("Camera not Authorized")
                        self.checkCamera()
                        return
                    }
                }
            });
        }

您需要设置一对新的Info.plist值，与位置服务的字符串在iOS8中相同：

只需为这些设置您的说明字符串。
