前期設(shè)置
iOS10 中需要在plist文件中添加獲取權(quán)限聲明，否則會(huì)崩潰，提示信息如下：

[access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSMicrophoneUsageDescription key with a string value explaining to the user how the app uses this data.

plist中的設(shè)置如下圖
這里寫(xiě)圖片描述

1.檢測(cè)麥克風(fēng)權(quán)限

//檢查麥克風(fēng)權(quán)限
- (void) checkAudioStatus{
    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    switch (authStatus) {
        case AVAuthorizationStatusNotDetermined:
        //沒(méi)有詢問(wèn)是否開(kāi)啟麥克風(fēng)
        self.audioStatus = @"AVAuthorizationStatusNotDetermined";
        break;
        case AVAuthorizationStatusRestricted:
        //未授權(quán)，家長(zhǎng)限制
        self.audioStatus = @"AVAuthorizationStatusRestricted";
        break;
        case AVAuthorizationStatusDenied:
        //玩家未授權(quán)
        self.audioStatus = @"AVAuthorizationStatusDenied";
        break;
        case AVAuthorizationStatusAuthorized:
        //玩家授權(quán)
        self.audioStatus = @"AVAuthorizationStatusAuthorized";
        break;
        default:
        break;
    }
}

2.獲取麥克風(fēng)權(quán)限

[AVCaptureDevice requestAccessForMediaType:AVMediaTypeAudio completionHandler:^(BOOL granted) {
           NSLog(@"%@",granted ? @"麥克風(fēng)準(zhǔn)許":@"麥克風(fēng)不準(zhǔn)許");
       }];

3.檢測(cè)相機(jī)權(quán)限

- (void) checkVideoStatus
{
    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    switch (authStatus) {
        case AVAuthorizationStatusNotDetermined:
        //沒(méi)有詢問(wèn)是否開(kāi)啟相機(jī)
        self.videoStatus = @"AVAuthorizationStatusNotDetermined";
        break;
        case AVAuthorizationStatusRestricted:
        //未授權(quán)，家長(zhǎng)限制
        self.videoStatus = @"AVAuthorizationStatusRestricted";
        break;
        case AVAuthorizationStatusDenied:
        //未授權(quán)
        self.videoStatus = @"AVAuthorizationStatusDenied";
        break;
        case AVAuthorizationStatusAuthorized:
        //玩家授權(quán)
        self.videoStatus = @"AVAuthorizationStatusAuthorized";
        break;
        default:
        break;
    }
}

4.獲取相機(jī)權(quán)限

 //授權(quán)相機(jī)
- (void)videoAuthAction
{
    [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
        NSLog(@"%@",granted ? @"相機(jī)準(zhǔn)許":@"相機(jī)不準(zhǔn)許");
    }];
}

5.檢測(cè)照片權(quán)限

//檢查照片權(quán)限
- (void) checkPhotoStauts{
    PHAuthorizationStatus photoAuthorStatus = [PHPhotoLibrary authorizationStatus];
    switch (photoAuthorStatus) {
        case PHAuthorizationStatusAuthorized:
        self.photoLibraryStatus = @"PHAuthorizationStatusAuthorized";
        break;
        case PHAuthorizationStatusDenied:
        self.photoLibraryStatus = @"PHAuthorizationStatusDenied";
        break;
        case PHAuthorizationStatusNotDetermined:
        self.photoLibraryStatus = @"PHAuthorizationStatusNotDetermined";
        break;
        case PHAuthorizationStatusRestricted:
        self.photoLibraryStatus = @"PHAuthorizationStatusRestricted";
        break;
        default:
        break;
    }
   }

6.獲取照片權(quán)限

//授權(quán)照片
- (void)phontLibraryAction{
    [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
    }];
}
