iOS上传语音、文字、图片

需求：用户可能提交 文字，也可能有语音，还有可能有图片。当然 都有也是可以的。
在这里我的方案是 先做判断（因为我提交的类不同（也就是方法不一样））；

（1）if (_imageArray.count == 0 && recordingInterval == 0){
//只有文字
}else{

// 文字 图片 加录音
}

// 有文字,有图,片有语音
+(void)askTextImageByUserInfoId:(NSString *)userInfoId
WithUserRelationId:(NSString *)userRelationId
WithAskContent:(NSString *)askContent
WithImageDataArray:(NSMutableArray *)imageDataArray
WithVoiceData:(NSData *)voiceData
success:(void (^)(id askDescArray))success
failure:(void (^)(NSError *error))failure`

/**

*
*  @param request 自定义的Request请求
*  @param userInfoId 对应人的唯一标示（用户本人  和  关系人）
*  @param token token值
