Answer 1

在你的ViewDidLoad()这个

viewDidLoad(){
    super.viewDidLoad()
    collectionView?.collectionViewLayout.incomingAvatarViewSize = .zero
    collectionView?.collectionViewLayout.outgoingAvatarViewSize = .zero
}

我也有这个功能，但我会假设基本相同。

override func collectionView(collectionView: JSQMessagesCollectionView!, avatarImageDataForItemAtIndexPath indexPath: NSIndexPath!) -> JSQMessageAvatarImageDataSource? {
    return nil
}

Answer 2

加载聊天记录后使用：

 dispatch_async(dispatch_get_main_queue(), ^{
    [self.collectionView reloadData];
});

此代码在目标 c 中，但我相信您可以将其转换为 swift :)
