我对Xcode来说是全新的，而且一般来说编程也不是很好。所以请好好的！
我制作了一个标签更新的小游戏，因此每次按下按钮都会出现挑战。我用开关盒完成了这件事。
我想要这个游戏的另一个小功能，用户可以在文本字段中键入他们想要的任何挑战，文本字段写入数组或其他内容。必须在switch-case-part中添加新的挑战作为案例，因此当用户按下“挑战”按钮时，用户可能会遇到自己的挑战。
我曾尝试了很多东西，但没有什么能帮助我，所以我只是想知道，如果你们中有人有完整的答案吗？我的问题标有＆＃39; //这是我的问题所在。有什么建议吗？＆＃39;在.m。
对不起，如果其他人之前曾问过类似的问题。我无法找到它。
另外，我在找到这个问题的正确标题时遇到了一些麻烦？
谢谢！

首先，我建议将所有挑战放入阵列中。它将使您的代码更清晰，更易于阅读，更易于维护。
然后，您只需将用户的挑战添加到阵列即可。
当谈到随机选择挑战时，您可以这样做：
int text = rand() % array.count;
//Check the value is a valid index:
if (text >= 0 && <= (array.count - 1))
{
ShowChallenge.text = array[text];
}
