因未捕获的异常终止应用程序' NSInvalidArgumentException',原因:' - [SWRevealViewController revealToggel:]

标签: ios swift unrecognized-selector

我正在关注使用Swift创建iOS应用程序的Apple教程[开发iOS应用程序(Swift)],我完全按照原样执行每一步。这个应用程序在模拟器中一直运行良好,但突然它开始抛出SIGABRT错误(我做了一个简短的研究,以了解SIGABRT(信号中止)错误是什么,我甚至找到了一些其他答案,但没有似乎解决了我的问题。)

控制台输出:

错字?应该是ngOnInit(): void { this.siteService.socket.on("users_online_now", function(usersOnlineNow){ this.usersOnlineNow = usersOnlineNow; console.log(usersOnlineNow); }); } ...

我认为你拼错了Red [] view [ text "Value of x:" f1: field "" return text "Value of y:" f2: field "" return text "Read Sum:" tt: text "" return button "Calculate" [ tt/text: to-string ((to-integer f1/text) + (to-integer f2/text)) ] button "Quit" [quit] ] 。它应该是revealToggel:
