创建方法初始化发送方和接收方的颜色，如下面的代码：

  - (JSQMessagesBubbleImage *) setupOutgoingBubble {
    JSQMessagesBubbleImageFactory *bubbleImageFactory = [[JSQMessagesBubbleImageFactory alloc] init];
    JSQMessagesBubbleImage * imgBubble = [bubbleImageFactory outgoingMessagesBubbleImageWithColor:[UIColor blueColor]];//jsq_messageBubbleBlueColor return imgBubble;
    return imgBubble;
}

- (JSQMessagesBubbleImage *) setupIncomingBubble {
    JSQMessagesBubbleImageFactory *bubbleImageFactory = [[JSQMessagesBubbleImageFactory alloc] init];
    JSQMessagesBubbleImage * imgBubble = [bubbleImageFactory outgoingMessagesBubbleImageWithColor:[UIColor greenColor]];//jsq_messageBubbleBlueColor return imgBubble;
    return imgBubble;
}




- (void)setupBubbleColors {
    self.incomingBubbleImageData = [self setupIncomingBubble];
    self.outgoingBubbleImageData = [self setupOutgoingBubble];
}

并在 viewDidLoad 中调用上述方法，如下所示

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [self setupBubbleColors];

}

和 id JSQMessageBubbleImageDataSource 委托 return 适当的图像如下

- (id<JSQMessageBubbleImageDataSource>)collectionView:(JSQMessagesCollectionView *)collectionView
             messageBubbleImageDataForItemAtIndexPath:(NSIndexPath *)indexPath {
    Message *message = [_messages objectAtIndex:indexPath.row];
    NSLog(@"%@", message.type);
    if(message.isOwnMessageValue) {
        return self.outgoingBubbleImageData;
    }
    else return self.incomingBubbleImageData;
}

输出将如下所示
