ios Upload Image and Text using HTTP POST

Here's code from my app to post an image to our web server:

// Dictionary that holds post parameters. You can set your post parameters that your server accepts or programmed to accept.NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];[_params setObject:[NSString stringWithString:@"1.0"] forKey:[NSString stringWithString:@"ver"]];[_params setObject:[NSString stringWithString:@"en"] forKey:[NSString stringWithString:@"lan"]];[_params setObject:[NSString stringWithFormat:@"%d", userId] forKey:[NSString stringWithString:@"userId"]];[_params setObject:[NSString stringWithFormat:@"%@",title] forKey:[NSString stringWithString:@"title"]];// the boundary string : a random string, that will not repeat in post data, to separate post data fields.NSString *BoundaryConstant = [NSString stringWithString:@"----------V2ymHFg03ehbqgZCaKO6jy"];// string constant for the post parameter 'file'. My server uses this name: `file`. Your's may differ NSString* FileParamConstant = [NSString stringWithString:@"file"];// the server url to which the image (or the media) is uploaded. Use your server url hereNSURL* requestURL = [NSURL URLWithString:@""]; // create requestNSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];                                    [request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];[request setHTTPShouldHandleCookies:NO];[request setTimeoutInterval:30];[request setHTTPMethod:@"POST"];// set Content-Type in HTTP headerNSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", BoundaryConstant];[request setValue:contentType forHTTPHeaderField: @"Content-Type"];// post bodyNSMutableData *body = [NSMutableData data];// add params (all params are strings)for (NSString *param in _params) {    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];    [body appendData:[[NSString stringWithFormat:@"%@\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];}// add image dataNSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);if (imageData) {    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];    [body appendData:[[NSString stringWithString:@"Content-Type: image/jpeg\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];    [body appendData:imageData];    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];}[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];// setting the body of the post to the reqeust[request setHTTPBody:body];// set the content-lengthNSString *postLength = [NSString stringWithFormat:@"%lu",(unsigned long) [body length]];[request setValue:postLength forHTTPHeaderField:@"Content-Length"];// set URL[request setURL:requestURL];

XJones' answer worked like charm.

But he didn't mentioned/declared variables _params, BoundaryConstant and requestURL. So, i thought of posting that part as an add-on to his post, so that it may help others in future.

Use your server url hereNSURL* requestURL = [NSURL URLWithString:@""]; 

As i mentioned earler, this is not an answer by itself, just an addon to XJones' post.
