循环更改按钮的文本

Question

我有4个UIButton和4个属​​性的集合：option1 ... option4。我想使用for循环来制作它，但我只是想不通。

for button in 0...(answerButtons.count - 1) {
    answerButtons[button].setTitle("string"//want to change this  , for: .normal)
}

Answer 1

根据您在问题和评论中所描述的内容，也许考虑一下答案按钮数组和答案标题数组，并在循环中为两者使用相同的索引。

let answers:[String]=//answers here
let buttons:[UIButton]=//buttons here

for i in 0..<buttons.count{
    buttons[i].setTitle(answers[i], for: .normal)
}

我希望这会有所帮助。

Answer 2

也许是这样

let titles : [String] = ["Option 1", "Option 2", "Option 3", "Option 4"]
let answerButtons: [UIButton] = [...]

for (key, button) in answerButtons.enumerated() {
    button.setTitle(answers[key], for: .normal)
}

Answer 3

您可以简单地点赞，

@IBOutlet var answerButtons: [UIButton]!

for (index, button) in answerButtons.enumerated() {
    button.setTitle("Option \(index)", for: .normal)
}
