本文介绍了玩游戏后复位阵列?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我在iOS中做了一个小测验,其中x code,我现在已经是一个产生20个随机回答了数组的一个测验,它控制标签的文本时按下一个按钮来检查答案是正确的。答案也是随机生成的,我确信,有没有使用相同的文字mulple答案。我的问题是,当一个问题被问,我改变一个对象的文本在我阵列删除;但是,当我把我所做的测验后重新开始,我的阵列有20个对象以字符串删除;我的问题是:我怎样才能恢复我的数组这是正常的对象?这里是我的全code,忽视了评论,但它是一种垃圾,因为我是新来的iOS编程:

解决方案

要么就比赛一开始arrEurope的副本,当游戏重新启动或使用一些其他的阵列中删除标记的问题还原到它。我会亲自尝试使用选项2。

I made a quiz in iOS with xcode, what i have now is a quiz that generates 20 random answers out of an array, it controls the text of the labels when a button is pushed to check if the answer is correct. The answers are also random generated and i made sure that there weren't mulple answers with the same text. My problem is that when a question is asked, i change the text of an object in my array to "removed"; but when i push start again after i've done the quiz, my array has 20 objects with the string "remove"; my question is: How can I reset my array to it's normal objects? Here is my full code, ignore the comments but it's kind of a junk cause i'm new to ios programming:

解决方案

Either make a copy of arrEurope on game start and restore to it when the game is restarted or use some other array to mark a question as removed. I would personally try to use option 2.
