用AFNetworking上传图片

其实我弄了好久，也没弄好多张一起上传，只好弄单张上传，如果你看到这篇文章对您有帮助的话欢迎您及时完善我的信息，也让我学习一下多张上传怎么弄，谢谢

//首先实例化一个AFHTTPRequestOperationManager操作对象

  AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:@"上传图片的接口"]];
    
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
    NSString *documentsDirectory = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"logo1.jpg"];
    NSData *logoJpg = [NSData dataWithContentsOfFile:documentsDirectory];
   UIImage * image = [UIImage imageWithData:logoJpg];

上面是从手机路径中取图片
    //    NSURL *filePath = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"avatar.jpg" ofType:nil]];
    
    NSData *imageData = UIImageJPEGRepresentation(image, 1.0);//压缩
   

 UIImage *image = [UIImage imageNamed:@"头像1"];
      NSData *data = UIImagePNGRepresentation(image);
         
         // 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
         NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
         // 设置时间格式
         formatter.dateFormat = @"yyyyMMddHHmmss";
         NSString *str = [formatter stringFromDate:[NSDate date]];
         NSString *fileName = [NSString stringWithFormat:@"%@.png", str]; 
         /*
         此方法参数
         1. 要上传的[二进制数据]
         2. 对应网站上[upload.php中]处理文件的[字段"file"]
          3. 要保存在服务器上的[文件名]
         4. 上传文件的[mimeType]
          */

    if (imageData) {
        NSDictionary * dic1 = @{};//接口要求的参数
        NSMutableURLRequest *request = [manager.requestSerializer
                                        multipartFormRequestWithMethod:@"POST"
                                        URLString:@"http://yapi.chelehuo.net/upload"
                                        parameters:dic1
                                        constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
                                            
                                            [formData appendPartWithFileData:imageData
                                                                        name:@"logo1"
                                                                    fileName:@"logo1.jpg"
                                                                    mimeType:@"image/jpeg"];
                                            
                                        }
                                        error:nil];
        
        AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
            NSLog(@"operation1:%@", responseObject);
           弄你想要的参数
        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            NSLog(@"failure. upload....");
        }];
        [manager.operationQueue addOperation:operation];
        //可以查看上传的进度
        [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
            
            NSLog(@"百分比:%f",totalBytesWritten*1.0/totalBytesExpectedToWrite);
            
        }];
    }

多张图片上传的方法

方法一:

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer]multipartFormRequestWithMethod:@"POST" URLString:url parameters:url参数 constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

        for (int i = 0; i<arrayImage.count; i++) {

            UIImage *uploadImage = arrayImage[i];

            [formData appendPartWithFileData:UIImagePNGRepresentation(uploadImage)name:[NSString stringWithFormat:@"参数%d",i+1] fileName:@"test.jpg"mimeType:@"image/jpg"];

        }

    } error:nil];

AFHTTPRequestOperation *opration = [[AFHTTPRequestOperationalloc]initWithRequest:request];   

opration.responseSerializer.acceptableContentTypes = [NSSetsetWithObject:@"text/html"];

[opration setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, idresponseObject) {

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

}

这个多张上传我是失败的不知道为啥

这是我在网上看到的几个博客里的例子，可以看看
