我将'XBChatModule'Cocoapods 中的库集成到我的项目中。

当我第一次运行代码时，它通过抛出以下错误使应用程序崩溃-[XBMessage messageHash]: unrecognized selector sent to instance并通过XBMessage.m如下更改文件得到解决

XBMessage.m

- (NSUInteger)messageHash
{
    return self.hash;
}

但这会产生新的问题说

Assertion failure in -[ChatMessagesController collectionView:cellForItemAtIndexPath:], /Users/Neelacharya/Harshit/LIve Projects/Project/V1/Source/Project/Pods/JSQMessagesViewController/JSQMessagesViewController/Controllers/JSQMessagesViewController.m:452

我了解崩溃的原因是成员messageSenderId 在 JSQMessagesViewController.m文件的第 452 行为零。但我不知道它为什么会发生以及如何解决它。

我还向Github的作者报告了问题，但没有得到回复。

如果您能帮助我解决问题，我将不胜感激。

它认为应用程序在这条线上崩溃：

NSString *messageSenderId = [messageItem senderId];
NSParameterAssert(messageSenderId != nil);

当我深入研究时，我发现senderId是从XBMessageViewController'sloadDataToTable方法设置的。我能找到值的唯一原因senderId是 nil 是您没有设置jidStrand的值senderId。

您将需要设置jidStr和senderId，接收者XBMessageViewController在哪里，并且是自己的用户。jidStrsenderId

希望这可以帮助。

您需要注册您的课程，例如[self.collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:@"Cell"];
