I used Afnetworking in my app,I need to post 5 images to server, 5 images as array, this array was one of my **request parameters.
this is correct way or wrong one, there is any one more performance than it ? -
(IBAction)sPActionButton:(id)sender {
NSUserDefaults *def=[NSUserDefaults standardUserDefaults];
NSString * language=[def objectForKey:#"Language"];
NSString * deviceToken=[def objectForKey:#"dT"];
[par setObject:deviceToken forKey:#"dT"];
NSString *check=[def objectForKey:#"Log"];
[par setObject:check forKey:#"aT"];
//---------------------------------------------
NSString * apiKey=APIKEY;
[par setObject:apiKey forKey:#"aK"];
[par setObject:language forKey:#"lG"];
NSMutableArray *images = [NSMutableArray arrayWithCapacity:10];
for (int x=0; x<_chosenImages.count; x++) {
NSData *imageData = UIImageJPEGRepresentation(_chosenImages[x], 0.5);
NSLog(#"%#",imageData);
NSString *str=[Base64 encode:imageData];
[images addObject:str];
}
NSLog(#"%#",images);
[par setObject:images forKey:#"image[array]"];
if ([self validateAllFields]) {
NSLog(#"par = %#",par);
//-----------------------------------------------
[MBProgressHUD showHUDAddedTo:self.view animated:NO];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:[NSString stringWithFormat:#"%#/sellPrp?",BASEURl] parameters:par
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error Retrieving Data"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alertView show];
[MBProgressHUD hideHUDForView:self.view animated:NO];
}];
}
}

- (void)prepareForImagePosting
{
if (imageCount < self.arrAllPostImages.count)//arrAllPostImages array contains images for posting and imageCount acts as iterator
{
NSMutableDictionary *dict = [[NSMutableDictionary alloc]init]; //Prepare the dictionary which contains image for posting
[dict setObject:#"1" forKey:#"upload"];
[dict setObject:[[self.arrAllPostImages objectAtIndex:imageCount]objectForKey:#"SelectedPhoto"] forKey:#"post_image"];

return;
