Ios 如何在swift 3中的滚动视图中将不同的文本设置为带有标签的标签？ homeScrollView.frame=CGRect（x:0，y:0，宽度：屏幕宽度，高度： homeView.bounds.size.height） 对于0..

我在

scrollview

中有9个标签，这是

homescrollview

，我想给每个标签赋予不同的文本。我已经为每个标签分配了标签，但我不知道如何使用标签访问这些标签。感谢您提供的任何帮助。

您可以通过

viewWithTag

方法访问它们：

homeScrollView.frame = CGRect(x: 0, y: 0, width: screenWidth, height: 
homeView.bounds.size.height)

for i in 0 ..< 3 {
    scrollBtnLbl1 = UILabel()
    scrollBtnLbl2 = UILabel()
    scrollBtnLbl3 = UILabel()

    scrollViewStartHeight = scrollViewStartHeight+50

    scrollBtnLbl1.frame = CGRect(x: (screenWidth-450)*1/4, y: scrollViewStartHeight+180, width: 150, height: 30)

    scrollBtnLbl1.text = "about worldcup"
    scrollBtnLbl1.font = UIFont(name: "Metropolis-Regular", size: 15)
    scrollBtnLbl1.textColor = UIColor.black
    scrollBtnLbl1.textAlignment = .center
    scrollBtnLbl1.tag = i


    homeScrollView.addSubview(scrollBtnLbl1)


    scrollBtnLbl2.frame = CGRect(x: (screenWidth-450)*2/4 + 150, y: scrollViewStartHeight+180, width: 150, height: 30)

    scrollBtnLbl2.text = "top goals"
    scrollBtnLbl2.font = UIFont(name: "Metropolis-Regular", size: 15)
    scrollBtnLbl2.textColor = UIColor.black
    scrollBtnLbl2.textAlignment = .center
    scrollBtnLbl2.tag = i

    homeScrollView.addSubview(scrollBtnLbl2)

    scrollBtnLbl3.frame = CGRect(x: (screenWidth-450)*3/4 + 300, y: scrollViewStartHeight+180, width: 150, height: 30)

    scrollBtnLbl3.text = "top goals"
    scrollBtnLbl3.font = UIFont(name: "Metropolis-Regular", size: 15)
    scrollBtnLbl3.textColor = UIColor.black
    scrollBtnLbl3.textAlignment = .center
    scrollBtnLbl3.tag = i

    homeScrollView.addSubview(scrollBtnLbl3)

    scrollViewStartHeight = scrollViewStartHeight+300

}

我已经声明了3个标签如何找到确切的标签。您将通过为

UILabel

设置的

标签

找到，请参见编辑

if let lbl = self.view.viewWithTag(1 /*your UILabel tag*/) as? UILabel {
    lbl.text = "some text"
}
