 - (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];

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

   }

 - (QBChatMessage *)messageForIndexPath:(NSIndexPath *)indexPath {
         if (indexPath.item == NSNotFound) {
          // If the update item's index path has an "item" value of NSNotFound, it means it was a section update, not an individual item.

     }

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

Solution 1

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.

Solution 2

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

"Static cell" to "Dynamic prototypes".

This code is not working for me, showing same error.

@preetipatel Please check your method (Number of item in collection view). i think you created number of item with different array count which you use in cell for item

[HardikDG]

@preetipatel ok , are you using the quickblox sample demo or created your new demo, if you are using same please provide link so we can check in the code itself

[PPreeti]

I have created my own with the help of sample demo

[Walid]

You, you save my day :)

This does indeed reveal the issue immediately. Thanks for sharing.
