//网络提交图片信息
- (void)postWithManager:(AFHTTPRequestOperationManager *)manager url:(NSString *)url parameter:(NSDictionary *)parameter{

          }
          
     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     }];
     
}

这个是单张图片发送

下面弄个多图的

- (void)postWithManager:(AFHTTPRequestOperationManager *)manager url:(NSString *)url parameter:(NSDictionary *)parameter{
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
    manager.requestSerializer.timeoutInterval = 20;
    [manager POST:url parameters:parameter constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        for (int i = 0 ; i < _imgArr.count - 1; i++) {
            NSData *imgData = UIImageJPEGRepresentation(_imgArr[i], 0.5);
            [formData appendPartWithFileData:imgData
                                        name:[NSString stringWithFormat:@"file%d",i + 1]
                                    fileName:@"ceshi.png" mimeType:@"image/jpeg"];
        }
        
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        if([responseObject[0][@"status"] isEqualToString:@"1001"]){
         
        }else{
        }
       
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    }];
    
}
