Question

我将如何编码：选择标题标签的按钮.text等于"类别">

@IBOutlet var buttons: [UIButton]!
var category: String?
override func viewDidLoad() {
super.viewdidload()
//I want to put the code here!
}

Answer 1

以下是filter该按钮的方法

let requiredButton = buttons
.filter{ $0.titleLabel?.text == "category" }.first

您也可以通过first实现这一目标

let butt =   buttons.first(where: { $0.titleLabel?.text == "category" })
