Detailed Description

The JSQMessagesCollectionViewDelegateFlowLayout protocol defines methods that allow you to manage additional layout information for the collection view and respond to additional actions on its items. The methods of this protocol are all optional.

Method Documentation

- (void) collectionView: (JSQMessagesCollectionView *)  collectionView didTapAvatarImageView: (UIImageView *)  avatarImageView atIndexPath: (NSIndexPath *)  indexPath

optional

Notifies the delegate that the avatar image view at the specified indexPath did receive a tap event.

Parameters

collectionView	The collection view object that is notifying the delegate of the tap event.
avatarImageView	The avatar image view that was tapped.
indexPath	The index path of the item for which the avatar was tapped.

- (void) collectionView: (JSQMessagesCollectionView *)  collectionView didTapCellAtIndexPath: (NSIndexPath *)  indexPath touchLocation: (CGPoint)  touchLocation

optional

Notifies the delegate that the cell at the specified indexPath did receive a tap event at the specified touchLocation.

Parameters

collectionView	The collection view object that is notifying the delegate of the tap event.
indexPath	The index path of the item for which the message bubble was tapped.
touchLocation	The location of the touch event in the cell's coordinate system.

Warning

This method is only called if position is not within the bounds of the cell's avatar image view or message bubble image view. In other words, this method is not called when the cell's avatar or message bubble are tapped. There are separate delegate methods for these two cases.
