以编程方式标记NSMutableAttributedString 4
以编程方式标记NSMutableAttributedString 4
提问于 2018-06-11 08:55:42
我必须确保我可以点击“隐私”这个词，以便打开一个网页链接。我试着用我发现的建议，但它们都是老东西，它们似乎不再起作用了。我不知道如何解决这个问题。
private lazy var firstTermDescriptionLabel: UILabel = {
let label = UILabel(frame: .zero)
let firstTermsMessage = "I Agree to the License Terms and Privacy Policy"
var attributedString = NSMutableAttributedString.init(string: "Privacy")
attributedString.addAttribute(.link, value: "https://www.google.com/url?q=https://www.iubenda.com/privacy-policy/58446596&sa=D&source=hangouts&ust=1528787597335000&usg=AFQjCNEPkofPxSm7TDRMvxjOjCz5cio27w", range: NSRange(location: 0, length: 7))
label.isUserInteractionEnabled = true
label.text = firstTermsMessage
label.font = UIFont.systemFont(ofSize: 13, weight: .regular)
label.textAlignment = .left
label.numberOfLines = 0
label.translatesAutoresizingMaskIntoConstraints = false
label.heightAnchor.constraint(equalToConstant: 36).isActive = true
return label
}()

更新为Swift 4
将此扩展添加到项目中
extension NSMutableAttributedString {
public func setAsLink(textToFind:String, linkURL:String) -> Bool {
let foundRange = self.mutableString.range(of: textToFind)
if foundRange.location != NSNotFound {
// self.addAttribute(NSLinkAttributeName, value: linkURL, range: foundRange)
self.addAttributes([NSAttributedStringKey.link: URL(string: linkURL)!], range: foundRange)
return true
}
return false
}
}改变你的如下方式：
let firstTermsMessage = "I Agree to the License Terms and Privacy Policy"
let attributedString = NSMutableAttributedString(string:firstTermsMessage)
let linkWasSet = attributedString.setAsLink(textToFind: "Privacy", linkURL: "https://www.google.com/url?q=https://www.iubenda.com/privacy-policy/58446596&sa=D&source=hangouts&ust=1528787597335000&usg=AFQjCNEPkofPxSm7TDRMvxjOjCz5cio27w")
if linkWasSet {
// adjust more attributedString properties
}
lableAtt.attributedText = attributedString
lableAtt.isUserInteractionEnabled = true
lableAtt.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleTapOnLabel(_:))))
@objc func handleTapOnLabel(_ recognizer: UITapGestureRecognizer) {
guard let text = lableAtt.attributedText?.string else {
return
}
if let range = text.range(of:"terms") {
// goToTermsAndConditions()
} else if let range = text.range(of: "Privacy"){
print(range)
UIApplication.shared.open(URL(string: "https://www.google.com/url?q=https://www.iubenda.com/privacy-policy/58446596&sa=D&source=hangouts&ust=1528787597335000&usg=AFQjCNEPkofPxSm7TDRMvxjOjCz5cio27w")!, options: [:])
}

如果您准备使用一些第三方代码，TTTAttributedLabel是一个广泛使用的“插入替代UILabel”，它可以让您轻松地嵌入链接！
