嗯之前在网上找了很多资源，看了很多，也很乱，大概总结了一下
1）上传一张图片：（该段代码是自己项目中的一段代码，为注册模块）
AFHTTPRequestOperationManager *manager=[AFHTTPRequestOperationManager manager];;
NSDictionary *dic=@{@”tel”:self.tel,@”pwd”:self.pwd,@”shop_name”:self.shopName.text,@”address”:self.adress,@”lat”:self.lat,@”lng”:self.Ing};
NSString *fullPath = [[NSHomeDirectory() stringByAppendingPathComponent:@”Documents”] stringByAppendingPathComponent:@”currentImage.png”];
NSURL *url=[NSURL fileURLWithPath:fullPath];
[manager POST:@”http://appservice.ubi.cn/cheyouhui/merchant.php?m=Register&a=register” parameters:dic constructingBodyWithBlock:^(id formData)
{
[formData appendPartWithFileURL:url name:@”currentImage” error:nil];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@”Success: %@”, responseObject);

         _arrRegister = [NSMutableArray arrayWithObjects:@"", nil];         EDTabBarController *root = [[EDTabBarController alloc]init];         [UIApplication sharedApplication].keyWindow.rootViewController = root;         //弹出提示框         [EDPoping showInRect:CGRectMake(80, 120, self.view.frame.size.width - 160, 100) text:@"登录成功" image:[UIImage imageNamed:@"newSuccess"]];         dispatch_time_t when = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC));         //时间测试         dispatch_after(when, dispatch_get_main_queue(), ^{             [EDPoping dismiss];         });     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {         NSLog(@"Error: %@", error);     }];

2）上传多张图片
//上传多张图片
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];NSString *merchant_shop_id=[defaults objectForKey:@"merchant_shop_id"];NSDictionary *dic=@{@"merchant_shop_id":merchant_shop_id};//参数[manager POST:@"http://appservice.ubi.cn/cheyouhui/merchant.php?m=User&a=upload_shop_img" parameters:dic constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {     if(_arr.count>0)     {         NSObject *firstObject=[_arr objectAtIndex:0];         if([firstObject isKindOfClass:[UIImage class]])         {             for(NSInteger i=0;i<_arr.count;i++)             {                 UIImage *eachImage=[_arr objectAtIndex:i];                 if(eachImage!=nil)                 {                     // 在网络开发中，上传文件时，是文件不允许被覆盖，文件重名                    // 要解决此问题，                    // 可以在上传时使用当前的系统事件作为文件名                     NSData *eachImageData=UIImageJPEGRepresentation(eachImage, 0.5);                     NSDateFormatter  *formatterr=[[NSDateFormatter alloc]init];                     // 设置时间格式                     formatterr.dateFormat=@"yyyyMMddHHmmss";                     NSString *str=[formatterr stringFromDate:[NSDate date]];                     NSString *fileName=[NSString stringWithFormat:@"%@.jpg",str];                     /*                      Data: 需要上传的数据                      name: 服务器参数的名称                      fileName: 文件名称                      mimeType: 文件的类型                      */                     [formData appendPartWithFileData:eachImageData name:[NSString stringWithFormat:@"file%d",i+1] fileName:fileName mimeType:@"image/jpeg"];                 }             }         }     } }success:^(AFHTTPRequestOperation *operation, id responseObject) {     //请求成功     NSLog(@"请求成功 %@",responseObject); }failure:^(AFHTTPRequestOperation *operation, NSError *error) {     //请求失败     NSLog(@"请求失败 %@",error); }];dispatch_time_t when = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC));//时间测试dispatch_after(when, dispatch_get_main_queue(), ^{    [MBProgressHUD showSuccess:@"上传成功"];});[self.navigationController popViewControllerAnimated:YES];

}
又如
3)
- (IBAction)upLoad
{
// 创建一个管理者
AFHTTPRequestOperationManager *manger = [AFHTTPRequestOperationManager manager];
// 设置参数
NSMutableDictionary *params = [NSMutableDictionary dictionary];
params[@”username”] = @”123”;
params[@”pwd”] = @”123”;

// 设置URLNSString *url = @"http://192.168.15.56:8080/MJServer/upload";[manger POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {      注意：      在发送请求之前会自动调用这个block    需要在这个block中添加文件参数到formData中    NSData *fileData = UIImageJPEGRepresentation(self.imageV.image, 1.0);    [formData appendPartWithFileData:fileData name:@"file" fileName:@"image.png" mimeType:@"image/png"];} success:^(AFHTTPRequestOperation *operation, id responseObject) {    NSLog(@"上传成功");} failure:^(AFHTTPRequestOperation *operation, NSError *error) {    NSLog(@"上传失败");}];

}

注意：
1.保留照片的质量
NSData *fileData = UIImageJPEGRepresentation(self.imageV.image, 1.0);

2.AFN不能监听文件的上传进度，ASI可以监听文件的上传进度。

3.需要上传的文件的具体数据
FileData : 需要上传的文件的具体数据
name : 服务器那边接收文件用的参数名
fileName : （告诉服务器）所上传文件的文件名
mimeType : 所上传文件的文件类型
NSData *fileData = UIImageJPEGRepresentation(self.imageV.image, 1.0);
[formData appendPartWithFileData:fileData name:@”file” fileName:@”image.png” mimeType:@”image/png”];

4.需要上传的文件的URL路径
FileURL : 需要上传的文件的URL路径
name : 服务器那边接收文件用的参数名
fileName : （告诉服务器）所上传文件的文件名
mimeType : 所上传文件的文件类型
NSURL *url = [[NSBundle mainBundle] URLForResource:@”itcast” withExtension:@”txt”];
[formData appendPartWithFileURL:url name:@”file” fileName:@”test.txt” mimeType:@”text/plain” error:nil];
