ios app第一次上架遇到的审核问题

第一次提交

2.1.0 性能：应用程序完整性

说启动app，拒绝授予相机权限后，app会崩溃

针对这个把代码增加了场景处理，在viewDidLoad会检查权限，如下：

Swift 复制代码

    override func viewDidLoad() {
        super.viewDidLoad()
        
        checkCameraPermission()
        
        cameraMgr.updateVideoOrientation()
        // 监听设备方向变化
        NotificationCenter.default.addObserver(
            self,
            selector: #selector(deviceOrientationDidChange),
            name: UIDevice.orientationDidChangeNotification,
            object: nil
        )
    }

    @objc func checkCameraPermission() {
        let status = AVCaptureDevice.authorizationStatus(for: .video)
        switch status {
        case .notDetermined:
            // 首次请求权限
            AVCaptureDevice.requestAccess(for: .video) { granted in
                if granted {
                    print("相机权限已授予")
                    DispatchQueue.main.async {
                        self.setupCameraAndAudio()
                    }
                } else {
                    print("相机权限被拒绝")
                    DispatchQueue.main.async {
                        self.showPermissionDeniedLabel()
                    }
                }
            }
        case .authorized:
            print("相机权限已授权")
            setupCameraAndAudio()
        case .denied, .restricted:
            print("相机权限被拒绝或受限制")
            // 可以提示用户去设置中手动开启权限
            showPermissionDeniedLabel()
        @unknown default:
            break
        }
    }

checkCameraPermission，触发请求权限，是在安装后第一次执行时，AVCaptureDevice.requestAccess(for: .video)执行后，在设置里会有相机权限可选:：

如果用户不授予，弹出下面页面，引导用户去设置。

Swift 复制代码

func showPermissionDeniedLabel() {
        let label = UILabel()
        label.text = "app需要相机权限，用来进行人脸测距。\n请打开：设置->App->faceDistancePIP，打开相机权限，则可使用app的完整功能。"
        label.numberOfLines = 0
        label.lineBreakMode = .byWordWrapping
        label.textAlignment = .center
        label.translatesAutoresizingMaskIntoConstraints = false
        self.view.addSubview(label)
        
        let settingsButton = UIButton(type: .system)
        settingsButton.setTitle("去设置", for: .normal)
        settingsButton.addTarget(self, action: #selector(openSettings), for: .touchUpInside)
        settingsButton.translatesAutoresizingMaskIntoConstraints = false
        self.view.addSubview(settingsButton)
        
        NSLayoutConstraint.activate([
            label.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20),
            label.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20),
            label.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: -20),
            
            settingsButton.topAnchor.constraint(equalTo: label.bottomAnchor, constant: 20),
            settingsButton.centerXAnchor.constraint(equalTo: view.centerXAnchor)
        ])
    }

    @objc func openSettings() {
        guard let settingsUrl = URL(string: UIApplication.openSettingsURLString) else {
            return
        }
        if UIApplication.shared.canOpenURL(settingsUrl) {
            UIApplication.shared.open(settingsUrl)
        }
    }
