iOS權(quán)限相關(guān)的檢測和申請

在iOS開發(fā)過程中常用到的權(quán)限整理如下：

1. 相冊權(quán)限檢測

PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
    switch (status) {
        case PHAuthorizationStatusNotDetermined:
            NSLog(@"用戶還未做出任何選擇");
            break;
        case PHAuthorizationStatusRestricted:
            NSLog(@"權(quán)限收到限制仿野，可能是家長控制權(quán)限");
            break;
        case PHAuthorizationStatusDenied:
            NSLog(@"沒有授權(quán)");
            break;
        case PHAuthorizationStatusAuthorized:
            NSLog(@"已經(jīng)授權(quán)");
            break;
        default:
            break;
    } 

相冊權(quán)限申請

[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
        if (status == PHAuthorizationStatusAuthorized) {
            NSLog(@"同意授權(quán)");
        }else{
            NSLog(@"未同意或未選擇");
        }
    }];

2. 相機權(quán)限檢測

AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    if (status == AVAuthorizationStatusAuthorized) {
        NSLog(@"有權(quán)限");
    }else{
        NSLog(@"沒有");
    }

相機權(quán)限申請

[AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
        if (granted) {
            NSLog(@"同意");
        }
    }];

3. 麥克風(fēng)
   把上面的AVMediaTypeVideo換成AVMediaTypeAudio即可

4. 網(wǎng)絡(luò)權(quán)限
   需要進入頭文件#import <CoreTelephony/CTCellularData.h

CTCellularData *cellularData = [CTCellularData new];
    CTCellularDataRestrictedState state = [cellularData restrictedState];
    if (state == kCTCellularDataRestricted) {
        NSLog(@"kCTCellularDataRestricted");
    }else if (state == kCTCellularDataNotRestricted){
        NSLog(@"kCTCellularDataNotRestricted");
    }else{
        NSLog(@"kCTCellularDataRestrictedStateUnknown");
    }

5. 推送權(quán)限檢測

UIUserNotificationSettings *setting = [[UIApplication sharedApplication] currentUserNotificationSettings];
    switch (setting.types) {
        case UIUserNotificationTypeNone:
            NSLog(@"在收到通知后耻陕，應(yīng)用程序可能不呈現(xiàn)任何UI镣屹。");
            break;
        case UIUserNotificationTypeBadge:
            NSLog(@"應(yīng)用程序可以在收到通知時標記其圖標。");
            break;
        case UIUserNotificationTypeSound:
            NSLog(@"應(yīng)用程序可以在接收到通知時播放聲音猪叙。");
            break;
        case UIUserNotificationTypeAlert:
            NSLog(@"應(yīng)用程序可以在接收到通知時顯示警報。");
            break;
        default:
            break;
    }

推送權(quán)限申請

UIUserNotificationSettings *requeatSet = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeSound | UIUserNotificationTypeBadge categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:requeatSet];

6. 通訊錄權(quán)限檢測

//ios9之前，檢測
    ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
    if (status == kABAuthorizationStatusAuthorized) {
        NSLog(@"有權(quán)限");
    }else{
        NSLog(@"沒有");
    }

//iOS9及以上，檢測
    CNAuthorizationStatus statu = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    if (statu == CNAuthorizationStatusAuthorized) {
        NSLog(@"有權(quán)限");
    }else{
        NSLog(@"沒有");
    }

通訊錄權(quán)限申請

//ios9之前眷篇，申請
ABAddressBookRef ref = ABAddressBookCreate();
    ABAddressBookRequestAccessWithCompletion(ref, ^(bool granted, CFErrorRef error) {
        if (granted) {
            NSLog(@"同意");
        }
    });

//iOS9及以上，申請
CNContactStore *store = [CNContactStore new];
    [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if (granted) {
            NSLog(@"同意");
        }
    }];

7. 定位權(quán)限檢測
   引入頭文件#import <CoreLocation/CoreLocation.h>

CLAuthorizationStatus status = [CLLocationManager authorizationStatus];
    switch (status) {
        case kCLAuthorizationStatusNotDetermined:
            NSLog(@"kCLAuthorizationStatusNotDetermined");
            break;
        case kCLAuthorizationStatusRestricted:
            NSLog(@"kCLAuthorizationStatusRestricted");
            break;
        case kCLAuthorizationStatusDenied:
            NSLog(@"kCLAuthorizationStatusDenied");
            break;
        case kCLAuthorizationStatusAuthorizedAlways:
            NSLog(@"kCLAuthorizationStatusAuthorizedAlways");
            break;
        case kCLAuthorizationStatusAuthorizedWhenInUse:
            NSLog(@"kCLAuthorizationStatusAuthorizedWhenInUse");
            break;
        default:
            break;
    }

定位權(quán)限申請

    CLLocationManager *manager = [CLLocationManager new];
    [manager requestAlwaysAuthorization];
    [manager requestWhenInUseAuthorization];
    manager.delegate = self;

//代理方法中判斷用戶的選擇
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{
    switch (status) {
        case kCLAuthorizationStatusNotDetermined:
            NSLog(@"kCLAuthorizationStatusNotDetermined");
            break;
        case kCLAuthorizationStatusRestricted:
            NSLog(@"kCLAuthorizationStatusRestricted");
            break;
        case kCLAuthorizationStatusDenied:
            NSLog(@"kCLAuthorizationStatusDenied");
            break;
        case kCLAuthorizationStatusAuthorizedAlways:
            NSLog(@"kCLAuthorizationStatusAuthorizedAlways");
            break;
        case kCLAuthorizationStatusAuthorizedWhenInUse:
            NSLog(@"kCLAuthorizationStatusAuthorizedWhenInUse");
            break;
        default:
            break;
    }
}
