Seems like by uiimage encoding is altered before POST request - ios

Question

I'm currently working on sending uiimages to my server to be stored on the server. So I get an image from the user gallery and then encode it using Base64 and then send it to my server. However all the images I sent to my server don't show. I'm wondering whether the post request I make with the base64encodedstring alters the encoded string.
Here is what I have done.
//Upload picture to server
NSData *imageData=UIImageJPEGRepresentation(showPic.image, 1.0f);
NSLog(#"The size of the image is %i",[imageData length]);
[Base64 initialize];
NSString *strEncoded = [Base64 encode:imageData];
//NSLog(#"This is the encoded string to be uploaded %#",encodedPic);
prefs=[NSUserDefaults standardUserDefaults];
userid=[prefs stringForKey:#"userid"];
NSLog(#" %# is the userid to be used to upload the pic",userid);
NSString *poster = #"username=";
poster = [poster stringByAppendingString:userid];
poster = [poster stringByAppendingString:#"&image="];
poster = [poster stringByAppendingString:strEncoded];
NSString *post = poster;
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://www.example.com/server/upload"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
