Swift-常用权限检测

1.选择导入头文件

import Photos
import AssetsLibrary
import MediaPlayer
import CoreTelephony
import CoreLocation
import AVFoundation

1.是否开启媒体资料库/Apple Music 服务

/// 是否开启媒体资料库/Apple Music 服务 需要iOS9.3之后可使用
@available(iOS 9.3, *)
func openMediaPlayerServiceWithBlock(action :@escaping ((Bool)->())) {
    let authStatus = MPMediaLibrary.authorizationStatus()
    if authStatus == MPMediaLibraryAuthorizationStatus.notDetermined {
        MPMediaLibrary.requestAuthorization { (status) in
            if (status == MPMediaLibraryAuthorizationStatus.authorized) {
                DispatchQueue.main.async {
                    action(true)
                }
            }else{
                DispatchQueue.main.async {
                    action(false)
                }
            }
        }
    } else if authStatus == MPMediaLibraryAuthorizationStatus.authorized {
        action(true)
    } else {
        action(false)
    }
}

2.检测是否开启联网

/// 检测是否开启联网
func hw_openEventServiceWithBolck(action :@escaping ((Bool)->())) {
    let cellularData = CTCellularData()
    cellularData.cellularDataRestrictionDidUpdateNotifier = { (state) in
        if state == CTCellularDataRestrictedState.restrictedStateUnknown ||  state == CTCellularDataRestrictedState.notRestricted {
            action(false)
        } else {
            action(true)
        }
    }
    let state = cellularData.restrictedState
    if state == CTCellularDataRestrictedState.restrictedStateUnknown ||  state == CTCellularDataRestrictedState.notRestricted {
        action(false)
    } else {
        action(true)
    }
}

3.检测是否开启定位

/// 检测是否开启定位
func hw_openLocationServiceWithBlock(action :@escaping ((Bool)->())) {
    var isOpen = false
    if CLLocationManager.locationServicesEnabled() || CLLocationManager.authorizationStatus() != .denied {
        isOpen = true
    }
    action(isOpen)
}

4.检测是否开启摄像头

/// 检测是否开启摄像头
func hw_openCaptureDeviceServiceWithBlock(action :@escaping ((Bool)->())) {
    let authStatus = AVCaptureDevice.authorizationStatus(for: AVMediaType.video)
    if authStatus == AVAuthorizationStatus.notDetermined {
        AVCaptureDevice.requestAccess(for: AVMediaType.video) { (granted) in
            action(granted)
        }
    } else if authStatus == AVAuthorizationStatus.restricted || authStatus == AVAuthorizationStatus.denied {
        action(false)
    } else {
        action(true)
    }
}

5.检测是否开启相册

/// 检测是否开启相册
func hw_openAlbumServiceWithBlock(action :@escaping ((Bool)->())) {
    var isOpen = true
    let authStatus = PHPhotoLibrary.authorizationStatus()
    if authStatus == PHAuthorizationStatus.restricted || authStatus == PHAuthorizationStatus.denied {
        isOpen = false;
    }
    action(isOpen)
}

6.检测是否开启麦克风

/// 检测是否开启麦克风
func hw_openRecordServiceWithBlock(action :@escaping ((Bool)->())) {
    let permissionStatus = AVAudioSession.sharedInstance().recordPermission()
    if permissionStatus == AVAudioSessionRecordPermission.undetermined {
        AVAudioSession.sharedInstance().requestRecordPermission { (granted) in
            action(granted)
        }
    } else if permissionStatus == AVAudioSessionRecordPermission.denied {
        action(false)
    } else {
        action(true)
    }
}

7.跳转系统设置界面

// MARK: - 跳转系统设置界面
func hw_OpenURL() {
    let url = URL(string: UIApplicationOpenSettingsURLString)
    let alertController = UIAlertController(title: "访问受限",
                                            message: "点击“设置”，允许访问权限",
                                            preferredStyle: .alert)
    let cancelAction = UIAlertAction(title:"取消", style: .cancel, handler:nil)
    let settingsAction = UIAlertAction(title:"设置", style: .default, handler: {
        (action) -> Void in
        if  UIApplication.shared.canOpenURL(url!) {
            if #available(iOS 10, *) {
                UIApplication.shared.open(url!, options: [:],completionHandler: {(success) in})
            } else {
                UIApplication.shared.openURL(url!)
            }
        }
    })
    alertController.addAction(cancelAction)
    alertController.addAction(settingsAction)
    UIApplication.shared.keyWindow?.rootViewController?.present(alertController, animated: true, completion: nil)
}
