Question

我目前正在处理文件处理应用程序，我已经使用AFNetworking完成了图像上传，其中包括来自相机和图库的多部分选择。但我的问题是如何从设备[iPhone]中选择pdf文件？如果你能给我一些答案，我将不胜感激。谢谢你在高级。

这是我的图片上传代码..

    AFHTTPRequestOperationManager *man = [[AFHTTPRequestOperationManager alloc]init];
    man.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
    int i=0;
    [self dispLoaderOnView:self.view loaderText:@"Loading.."];
    for(i=0 ; i< selectedImages.count; i++)
    {
        NSData *imageData = UIImagePNGRepresentation([selectedImages objectAtIndex:i]);



        AFHTTPRequestOperation *op = [man POST:FileUpload parameters:@{
                                                                       @"queryid":@"37",
                                                                       @"txtFilesQuery[]":imageData,
                                                                       @"selFileType[]":self.textFieldChooseFile.text,
                                                                       }
        constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {


        [formData appendPartWithFileData:imageData name:@"txtFilesQuery[]" fileName:[fileNamearray objectAtIndex:i] mimeType:@"image/png"];
                                                                       }
        success:^(AFHTTPRequestOperation *operation, id responseObject)
        {

        NSLog(@"Success: %@ ***** %@", operation.description, operation.responseString);

            if(i==selectedImages.count-1)
            {
                [self hideHUDLoader];
            }

            UIAlertView  *alert=[[UIAlertView alloc]initWithTitle:@"File Uploaded" message:@"Suucessfully.." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
            [alert show];

        } failure:^(AFHTTPRequestOperation *operation, NSError *error)
        {
            NSLog(@"Error: %@ ***** %@", operation.responseString, error);
        }];
        [op start];


    }

Answer 1

NSData * imageData = UIImagePNGRepresentation（[selectedImages objectAtIndex：i]）;

通过以下行

替换此代码

NSData * myData = [NSData dataWithContentsOfFile：[selectedImages objectAtIndex：i]];

和

[formData appendPartWithFileData：imageData name：@“txtFilesQuery []”fileName：[fileNamearray objectAtIndex：i] mimeType：@“image / png”];

按照
