Question

我正在创建一个应用程序，您按下按钮然后它会在标签中显示一个标记。然后我有一个按钮来清除信息。

实施例。如果我按下按钮，它将添加＆＃34; 1＆＃34;到标签＆＃34; labelTwo＆＃34;。用户按下按钮5次，labelTwo将显示＆＃34; 5＆＃34;。我点击＆＃34; clearButton＆＃34;它清除了它。

我的问题是，清除后，如果我按下按钮2，labelTwo将不会在＆＃34; 1＆＃34;但继续在＆＃34; 6＆＃34;好像我从未清除它。

谢谢

您需要在self.two方法中将clearButton:的值设置为零。将其添加到您的clearButton:方法：

self.one = 0;
self.two = 0;
self.three = 0;
self.four = 0;
self.five = 0;
