本文介绍了如何在iOS应用中实现相机、相册及录音权限的检查与请求。通过Objective-C代码示例，展示了不同权限状态下的处理逻辑，确保应用程序能够正确访问用户的隐私数据。

1、获取相机权限

+(BOOL)getCameraState
{
    //    NSString *mediaType = AVMediaTypeVideo;
    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    if(authStatus == ALAuthorizationStatusRestricted || authStatus == ALAuthorizationStatusDenied){
        return NO;
    }else{
        return YES;
    }
}

2、获取相册的读取权限

+(BOOL)getPhotoAlbumState
{
    NSString *tipTextWhenNoPhotosAuthorization; // 提示语
    ALAuthorizationStatus authorizationStatus = [ALAssetsLibrary authorizationStatus];
    // 如果没有获取访问授权，或者访问授权状态已经被明确禁止，则显示提示语，引导用户开启授权
    if (authorizationStatus == ALAuthorizationStatusRestricted || authorizationStatus == ALAuthorizationStatusDenied) {
        NSDictionary *mainInfoDictionary = [[NSBundle mainBundle] infoDictionary];
        NSString *appName = [mainInfoDictionary objectForKey:@"CFBundleDisplayName"];
        tipTextWhenNoPhotosAuthorization = [NSString stringWithFormat:@"%@%@%@",FPLocalizedString(@"openSetting"), appName,FPLocalizedString(@"AccessGallery")];
        return NO;
    }else{
        return YES;
    }
}

3、获取录音权限

+ (BOOL)getRecordState
{
    __block BOOL bCanRecord = YES;
    if ([[[UIDevice currentDevice] systemVersion] compare:@"7.0"] != NSOrderedAscending)
    {
        AVAudioSession *audioSession = [AVAudioSession sharedInstance];
        if ([audioSession respondsToSelector:@selector(requestRecordPermission:)]) {
            [audioSession performSelector:@selector(requestRecordPermission:) withObject:^(BOOL granted) {
                bCanRecord = granted;
            }];
        }
    }
    return bCanRecord;
}
