// COnvert Image to NSData
NSData *dataImage = UIImageJPEGRepresentation([UIImage imageNamed:#"icon.png"], 1.0f);
// set your URL Where to Upload Image
NSString *urlString = #"http://XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/imgupload.php";
// set your Image Name
NSString *filename = #"icon";
// Create 'POST' MutableRequest with Data and Other Image Attachment.
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 *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"%#.png\"\r\n",filename] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:dataImage]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
// Get Response of Your Request
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *responseString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"Response %#",responseString);

Hello, You can do it by using NSMutableArray
For Example :
NSMutableArray *arrayImageData = [[NSMutableArray alloc]init];
Take images from imagepicker
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissViewControllerAnimated:YES completion:nil];
NSString *filePath,*path;
NSData *dataImage = UIImageJPEGRepresentation([info objectForKey:#"UIImagePickerControllerOriginalImage"],1);
[arrayImageData addObject:dataImage];
filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:#"screenShot1.png"];
[picker dismissViewControllerAnimated:YES completion:nil];
}
At the time of posting image on Server use following code
for (int i = 0; i < [arrayImageData count]; i++)
{
[request setPostValue:[[MYUtility getInstance] base64StringFromNSData:[arrayImageData objectAtIndex:i]] forKey:[NSString stringWithFormat:#"Image%d", i + 1]];
}
Hope this will help for you...I used this code for saving multiple images on server.
