Answer 1

The code below is the solution.
-(void)setName:(NSString *)name withValue:(NSString *)value onBody:(NSMutableData *)body{
NSString *boundary = #"---------------------------14737809831466499882746641449";
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n\r\n",name] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[value dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
}
-(BOOL)SetRequest: (NSString *)offerID UserID: (NSString*) userID imageData:(NSData *) imageData RespData: (NSDictionary **)respData {
NSMutableData *body=[NSMutableData data];
//NSArray *paramNames = [NSArray arrayWithObjects:#"offerid", #"userid", nil];
//NSArray *paramDatas = [NSArray arrayWithObjects:offerID, userID, nil];
//NSDictionary *dict = [[NSDictionary alloc] initWithObjects:paramDatas forKeys:paramNames];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"API URL"]]];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
[self setName:#"userid" withValue:userID onBody:body];
[self setName:#"offerid" withValue:offerID onBody:body];
// Title text parameter
NSString *fileName = [NSString stringWithFormat:#"%#_%#.jpg",userID,offerID];
// NSData *uploadData = imageData;
//uploadData = UIImageJPEGRepresentation([UIImage imageWithData:imageData], 1.0f);
[self setName:#"parameterName" withFileName:fileName withValue:imageData onBody:body];
[request setHTTPBody:body];
[request setHTTPMethod:#"POST"];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
SBJsonParser *parser = [[[SBJsonParser alloc] init] autorelease];
NSDictionary *dic = (NSDictionary *)[parser objectWithString:returnString error:nil];
if (dic == nil)
return NO; // invalid JSON format
[dic retain];
*respData = dic;
return YES;
