问题描述

根据Appstore的评论，我的应用在特定时间崩溃。我如何在真实设备以及所有模拟器上试用过它，并且对我来说完全正常。我收到了崩溃日志并已将其表示出来。以下是结果：

以下是第523行的功能：

   // MARK: Check if current user is blocked i.e your self
    func checkIfCurrentUserBlocked(){
        if clientID.isEmpty {
            self.clientID = self.chatModobj.from_user_id!
        }
        //line 523
        apimanager.checkIfCurrentUserIsBlocked(self.clientID as! String,user_to: self.resid as! String,success: { (result) in
            if result == true {
                self.whenIAmBlocked()
            }else{
                print("You are not blocked")
            }
        }) { (error) in
            print("You are not Blocked")
        }

以下是viewdidload下第63行的调用中的函数：

 //line 63
        if self.clientName!.isEmpty{
            print("---->",self.chatModobj.from_username)
            self.clientName = self.chatModobj.from_username
        }

我无法跟踪崩溃的原因，因为它确实可以正常工作，并且在应用商店抱怨崩溃行63 self.clientName永远不会为空。
