I struggled with this for a while, if you are looking for uploading multiple images or any other file types, you can do the following using <code>AFNetworking 3.0</code>

<pre><code>NSDictionary *params = @{key : value,
 ..... etc
 };

 NSString *urlString = @"http://..... your endpoint url";

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer]; // only needed if the server is not returning JSON; 

NSURLSessionTask *task = [manager POST:urlString parameters:params constructingBodyWithBlock:^(id&lt;AFMultipartFormData&gt; formData) {
 for (int x = 0 ; x&lt; contentArray.count; x++) {
 AttachmentsModel *model = contentArray[x];

 if(model.type == ImageAttachmentType){
 [formData appendPartWithFileData:model.data name:model.name fileName:model.fileName mimeType:model.mimeType];

 }else if(model.type == AudioAttachmentType){
 NSURL *urlVideoFile = [NSURL fileURLWithPath:model.path];
 [formData appendPartWithFileURL:urlVideoFile name:model.name fileName:model.fileName mimeType:model.mimeType error:nil];
 }else{
 [formData appendPartWithFileURL:model.url name:model.name fileName:model.fileName mimeType:model.mimeType error:nil];

 }

 }
} progress:nil success:^(NSURLSessionTask *task, id responseObject) {
 [Utility stopLoading];

 NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
 NSLog(@"result = %@", result);

 id json = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil];


 if (block) {

 //your response comes here
 }

} failure:^(NSURLSessionTask *task, NSError *error) {
 NSLog(@"error = %@", error);

}];

if (!task) {
 NSLog(@"Creation of task failed.");
}
</code></pre>

And here is how my AttachmentsModel looks like:

<pre><code>// AttachmentsModel.h

typedef enum AttachmnetType{
 ImageAttachmentType,
 AudioAttachmentType,
 VideoAttachmentType
} AttachmnetType;

@interface AttachmentsModel : NSObject

@property (strong, nonatomic) NSString *path;
@property (strong, nonatomic) NSData *data;
@property (strong, nonatomic) NSString *mimeType;
@property (strong, nonatomic) NSString *name;
@property (strong, nonatomic) NSString *fileName;
@property (strong, nonatomic) NSURL *url;
</code></pre>

So this HTML code submits the data in the correct format for me.

<pre><code>&lt;form action="https://www.example.com/register.php" method="post" enctype="multipart/form-data"&gt;
 Name: &lt;input type="text" name="userName"&gt;&lt;BR /&gt;
 Email: &lt;input type="text" name="userEmail"&gt;&lt;BR /&gt;
 Password: &lt;input type="text" name="userPassword"&gt;&lt;BR /&gt;
 Avatar: &lt;input type="file" name="avatar"&gt;&lt;BR /&gt;
 &lt;input type="submit"&gt;
&lt;/form&gt;
</code></pre>

I've looked into a good number of articles on how to do a multipart/form-data POST on iOS, but none really explain what to do if there were normal parameters as well as the file upload.

Could you please help me with the code to POST this in Obj-C?

Thanks!
