iOS Photo Upload to a server - ios

Question

I've been trying for days on how to upload an image to an API. There is a cURL example there like this.
curl "http://address.com/api/" -F "parameter[name]=My Upload" -F "parameter[description]=this is my upload" -F "parameter[other]=additional info" -F "parameter[image]=#wake_2560x1600.jpg;type=image/jpg"
How would I use this to upload to a server via an NSMutableURLRequest & NSURLConnection? I have tried a few different ways but have not succeeded. Anyone have any ideas?
EDIT:
I'm currently trying out ASIFormDataRequest
NSData *imageData = UIImageJPEGRepresentation(image, 0.9);
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setDelegate:self];
[request addRequestHeader:#"User-Agent" value:#"iOS App"];
[request addPostValue:#"name" forKey:#"parameter[name]"];
[request addPostValue:#"description" forKey:#"parameter[description]"];
[request addPostValue:#"other" forKey:#"parameter[other]"];
[request addData:imageData withFileName:[NSString stringWithFormat:#"jpeg_%d.jpg", rand()] andContentType:#"image/jpeg" forKey:#"param[image]"];
[request startAsynchronous];

Rough way of doing it.
PHP Script.
<?php
$target_path = "./";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
?>
IOS code
- (void)upload:(UIImage *)image {
NSData *imageData = UIImageJPEGRepresentation(image, 80);
NSString *urlString = #"http://www.upload.com/upload.php"; // URL of upload script.
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", boundary];
[request addValue:contentType forHTTPHeaderField:#"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"returnString: %#", returnString);
}
Just make sure the variable name you use is the same, in here i use "uploadedfile" both for php and ioscode
php
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path))
ios
[body appendData:[#"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
// although right now im using https://github.com/samvermette/SVHTTPRequest
if you import that library in your code then making upload would be as easy as this
[SVHTTPRequest POST:#"http://www.upload.com/upload.php"
parameters:[NSDictionary dictionaryWithObjectsAndKeys:imageData, #"uploadedfile", nil]
progress:^(float progress) {
progressLabel.text = [NSString stringWithFormat:#"Uploading (%.0f%%)", progress*100];
}
completion:^(id response, NSHTTPURLResponse *urlResponse, NSError *error) {
progressLabel.text = #"Upload complete";
}];
