在我的 JSQMessagesViewController 中，当我加载短信气泡时，箭头方向始终是右侧。 如何将绿色气泡的箭头方向更改为向左？？
我的代码:
@interface AckChatViewController (){
JSQMessagesBubbleImage *outgoingBubbleImageView;
JSQMessagesBubbleImage *incomingBubbleImageView;
JSQMessagesAvatarImage *currentUserAvatar, *friendAvatar;
NSMutableArray *messages;
}
@end
@implementation AckChatViewController

最佳答案
问题出在这段代码中，您使用相同的方法初始化传出和传入
outgoingMessagesBubbleImageWithColor
尝试传入
incomingMessagesBubbleImageWithColor
和这个一起出去
outgoingMessagesBubbleImageWithColor
这个是对的
-(void)setupBubbles{
JSQMessagesBubbleImageFactory *bubbleImageFactory = [JSQMessagesBubbleImageFactory new];
outgoingBubbleImageView = [bubbleImageFactory outgoingMessagesBubbleImageWithColor:[UIColor jsq_messageBubbleBlueColor]];
incomingBubbleImageView = [bubbleImageFactory incomingMessagesBubbleImageWithColor:[UIColor jsq_messageBubbleGreenColor]];
}
关于ios - 气泡图像箭头始终指向正确的方向。如何将绿色气泡的箭头方向更改为向左？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40655965/
