text - Xcode - Button changing label to a series of words?

Question

I want a button to change a label's text in a set series. For example, that one box app on the app store where theres a button and every time you press it, it says the next thing. I want, let's say, one button and one label. The first time you press the button, it says, "hi", you press it again and it says, "how", then, "are", "you?". How would I go about doing this? Any help would be good.

Answer 1

1. 向视图控制器添加一个整数属性currentWordIndex，以记住哪个是当前单词。

2. 创建一个标签。将其连接到视图控制器中的插座，名称如wordLabel.

3. 创建一个按钮。将其连接到将标签更改为您想要的任何文本的操作，如下所示：

    - (IBAction)changeTheLabel:(id)sender
    {
        NSArray *words = @[@"hi", @"how", @"are", @"you?];
        self.currentWordIndex = (self.currentWordIndex + 1) % [字数];
        self.wordLabel.text = [words objectAtIndex:self.currentWordCount];
    }

就这些。
