由于项目需要整合多处的上传功能，涉及到的主要有数据库(FMDB)，多线程()

1、新建项目，下载依赖库

首先新建一个项目这里命名为UploadManager，项目依赖库采用CocoaPods来管理所以在终端进入UploadManager项目中，输入

pod init

# Uncomment this line to define a global platform for your project
# platform :ios, ‘6.0‘

target ‘UploadManager‘ do

end

target ‘UploadManagerTests‘ do

end

# Uncomment this line to define a global platform for your project
# platform :ios, ‘6.0‘

target ‘UploadManager‘ do
pod‘FMDB‘,‘2.5‘
end

target ‘UploadManagerTests‘ do

end

pod install

Analyzing dependencies

CocoaPods 0.37.1 is available.
To update use: `gem install cocoapods`

For more information see http://blog.cocoapods.org
and the CHANGELOG for this version http://git.io/BaH8pQ.

[!] Please close any current Xcode sessions and use `UploadManager.xcworkspace` for this project from now on.

3、数据库设计

首先是表结构设计，如下：

//  UploadManager
//
//  Created by 张杰 on 15/5/8.
//  Copyright (c) 2015年 张杰. All rights reserved.
//

#import <Foundation/Foundation.h>

@interface UploadTable : NSObject

@property (nonatomic, strong) NSString *upload_id;//协议、工单、临时工单的ID
@property (nonatomic, strong) NSString *upload_name;//协议、工单、临时工单的商户名称
@property (nonatomic, strong) NSString *upload_type;//协议：0;工单:1;临时工单：2
@property (nonatomic, strong) NSString *upload_text;//文字信息格式json
@property (nonatomic, strong) NSString *upload_img_name;//图片的名字格式json
@property (nonatomic, strong) NSString *upload_img_sys;//图片同步数据
@property int upload_progress;//UI的同步状态  上传进度:-1;未处理:0;文字上传中:1;文字上传失败:2;图片未上传:3;图片上传中:4;图片上传失败:5;图片同步中:6;图片同步失败:7;上传完成8
@property int upload_status;//线程中使用  0:未处理 1:文字已上传  2:图片已上传  3:同步成功
@property (nonatomic, strong) NSString *upload_show_text;//上传显示文字的进度
@property (nonatomic, getter = isStarting) BOOL starting; // 任务是否正在进行

@end
