使用 Swift 制作可点击的 UILabel
Make Clickable UILabel Using Swift
我想使用 Swift 在 UILabel
文本中设置可单击的特定单词。
可能吗?
如果此处有多个标签,我如何检测按下了哪个字词?
你不能用简单的标签来做。
github 中有可用的库。
https://github.com/TTTAttributedLabel/TTTAttributedLabel
由此您可以使用名为 yourLabel.addLinkToURL()
的方法
class ViewController: UIViewController , TTTAttributedLabelDelegate{
@IBOutlet var lbl: TTTAttributedLabel!
override func viewDidLoad() {
super.viewDidLoad()
var str : NSString = "Hello this is link"
lbl.delegate = self
lbl.text = str as String
var range : NSRange = str.rangeOfString("link")
lbl.addLinkToURL(NSURL(string: "http://github.com/mattt/")!, withRange: range)
}
func attributedLabel(label: TTTAttributedLabel!, didSelectLinkWithURL url: NSURL!) {
UIApplication.sharedApplication().openURL(url)
}
}
SWIFT 3.0
privacyLabel.delegate = self
let strPolicy : NSString = "Agree to the Terms & Conditions"
privacyLabel.text = strPolicy as String
let range1 : NSRange = strPolicy.range(of: "Terms & Conditions")
privacyLabel.addLink(to: URL(string: "http://Terms.com")!, with: range1)
func attributedLabel(_ label: TTTAttributedLabel!, didSelectLinkWith url: URL!) {
print("url \(url)")
// UIApplication.sharedApplication().openURL(url)
}

它包含 TTTAtributedLabel 的现代替代品 + 一套强大的方法来检测和设计不同的东西,如标签、主题标签、提及等(所有这些都可以点击)
一些代码来展示它是如何工作的:
let link = Style
.font(.boldSystemFont(ofSize: 14))
.foregroundColor(.black)
.foregroundColor(.red, .highlighted)
let tos = link.named("tos")
let pp = link.named("pp")
let all = Style
.font(.systemFont(ofSize: 14))
.foregroundColor(.gray)
let text = "<tos>Terms of Service</tos> and <pp>Privacy Policy</pp>"
.style(tags: tos, pp)
.styleAll(all)
let tosLabel = AttributedLabel()
tosLabel.textAlignment = .center
tosLabel.attributedText = text
tosLabel.onClick = { label, detection in
switch detection.type {
case .tag(let tag):
switch tag.name {
case "pp":
print("Privacy Policy clicked")
case "tos":
print("Terms of Service clicked")
default:
break
}
default:
break
}
}
view.addSubview(tosLabel)
