I am using Quickblox SDK.

This is the error..

        2016-04-26 10:22:50.510 Sample-VideoChat[1027:12093] *** Terminating  app due to uncaught exception 'NSRangeException', reason:     '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]'

  enter code here
  - (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView

     NSLog(@"self.chatSections....%@",self.chatSections);
     return [self.chatSections count];
 }


 - (UICollectionViewCell *)collectionView:(QMChatCollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
   {

    QBChatMessage *messageItem = [self messageForIndexPath:indexPath];

      NSRange textRange =[messageItem.text rangeOfString:@"https://api.quickblox.com/blobs/"];

     Class class = [self viewClassForItem:messageItem];
    NSString *itemIdentifier = [class cellReuseIdentifier];

     QMChatCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:itemIdentifier forIndexPath:indexPath];
cell.avatarView.tag = 0;

  if ((messageItem.attachments.count != 0) && textRange.location != NSNotFound) 
{

       QBChatAttachment* attachment = [[QBChatAttachment alloc] init];
         attachment.ID = @"3565772";
         attachment.url = messageItem.text;
         attachment.type = @"image";

return cell;
   }

          // If the update item's index path has an "item" value of NSNotFound, it means it was a section update, not an individual item.
        return nil;
     }

      QMChatSection *currentSection = self.chatSections[indexPath.section];
     return currentSection.messages[indexPath.item];

Static cells, I had the same issue. So, I just replaced the tableView content type

"Static cell" to "Dynamic prototypes".

try this:

if (item != nil && item.count != 0) {
    QMChatSection *currentSection = self.chatSections[indexPath.section];
    return currentSection.messages[indexPath.item];
}

You can make check like this, check for the value before you try to access the index 

  if (self.chatSections.count > 0) {
        QMChatSection *currentSection = self.chatSections[indexPath.section];
        if (currentSection.messages.count > 0){
            return currentSection.messages[indexPath.item];
        }else {
            return nil;
        }
    } else {
        return nil;
    }

If you are creating your own code with Quickblox you can refer their demo implementation as for me it works proper

Try adding an all-exception breakpoint (Add Exception Breakpoint) to debug where the exception occures. It does mean you are trying to access an object which is not in the index of array.

Best to find what is causing problem is to raise all exceptions before app crashes.
