Objective-C (Upload a Single Image to a Server) - ios

Question

All,
I just want to upload a single screenshot from my App to a server directory. The screenshot code works good as I can send it via SMS in another routine and it compiles just fine, but I don't see the image in the server directory using the code below.
I just can't get it to work. I ONLY care to upload the screenshotimage variable...the rest of the data is not important to me. Please Help!!!
- (IBAction)sendToServer {
UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *screenshotimage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData *imageData = UIImageJPEGRepresentation(screenshotimage,0.2);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"https://www.nameofmywebsite.com/temp/image_from_payer_app"]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"xxxxBoundaryStringxxxx";
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=\"userfile\"; filename=\"iphoneimage.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];
[request addValue:[NSString stringWithFormat:#"%lu", (unsigned long)[imageData length]] forHTTPHeaderField:#"Content-Length"];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"%#", returnString);
}
Here is my new code. I am only trying to send a single image file (which is a screenshot of the app) to a server. Can someone please verify that the client code is correct then I can just focus on the server side to see why the file is not being deposited on the server?
- (IBAction)sendToServer {
UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *screenshotimage = UIGraphicsGetImageFromCurrentImageContext();
NSData *imageData = UIImageJPEGRepresentation(screenshotimage,0.2);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://mywebsite.com/"]];
[request setHTTPMethod:#"POST"];
appendData:[NSData dataWithData:imageData];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"%#", returnString);
UIGraphicsEndImageContext();
NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if(conn) {
NSLog(#"Connection Successful");
} else {
NSLog(#"Connection could not be made");
}
}

Your client side code is seems ok. There might be some problem at your server side. Your server might unable to retrieve the image.
