iOS麦克风权限的检测和获取

前言

今天接到一个任务，检测应用是否有麦克风的权限，网上找了很多资料，然后终于明白了检测和获取的区别

检测权限

检测就是判断用户是否打开了麦克风的权限
判断方法是这样的

AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    switch (authStatus) {
        case AVAuthorizationStatusNotDetermined:
        //没有询问是否开启麦克风
            flag = 1;
            break;
        case AVAuthorizationStatusRestricted:
        //未授权，家长限制
            flag = 0;
            break;
        case AVAuthorizationStatusDenied:
        //玩家未授权
            flag = 0;
            break;
        case AVAuthorizationStatusAuthorized:
        //玩家授权
            flag = 2;
            break;
        default:
            break;
    }
    return flag;
}

获取权限

获取权限就会弹一个框，让用户选择是否开启这个权限

[audioSession performSelector:@selector(requestRecordPermission:) withObject:^(BOOL granted) {
             if (granted) {
                   bCanRecord = YES;
                }
                else {
                    bCanRecord = NO;
                   }
];
