我试图用UITextView制作可点击的电话号码。我设法让他们使用在Storyboard中创建的TextView，并将它们与@IBOutlet中的TextViews链接起来，就像How to display clickable links in UITextView中提到的那样。
但我无法点击动态生成的private func createPhoneNumber(text: String) -> UITextView {
let label = UITextView()
label.isEditable = false
label.isSelectable = true
label.isScrollEnabled = false
label.isUserInteractionEnabled = true
label.dataDetectorTypes = UIDataDetectorTypes.phoneNumber
let padding = label.textContainer.lineFragmentPadding
label.textContainerInset = UIEdgeInsetsMake(0, -padding, 0, -padding)
label.text = text
return label
}
，我无法选择只检查检测链接和行为可选，因为这些TextView是由代码而不是代码创建的在故事板中。
以下是我获取电话号码的功能之一
TextView这些是我动态生成标签TextView和链接private func createStackView(subViews: [UIView], xpadding: CGFloat) -> UIStackView {
let stackView = UIStackView(arrangedSubviews: subViews)
stackView.axis = .horizontal
stackView.distribution = .fillEqually
stackView.alignment = .fill
stackView.spacing = xpadding
stackView.translatesAutoresizingMaskIntoConstraints = false
return stackView
}
private func createLabelValue(text: String) -> UILabel {
let label = UILabel()
label.font = UIFont(name: label.font.fontName, size: CGFloat(14))
label.numberOfLines = 0
label.lineBreakMode = NSLineBreakMode.byWordWrapping
label.text = text
return label
}
private func createConstraints(item: Any, toItemXW: Any, toItemY: Any, YPadding: CGFloat) -> [NSLayoutConstraint] {
let DEFAULT_MULTIPLIER = CGFloat(1)
let DEFAULT_PADDING = CGFloat(8)
let xconstraint = NSLayoutConstraint(item: item, attribute: NSLayoutAttribute.leading, relatedBy: NSLayoutRelation.equal,
toItem: toItemXW, attribute: NSLayoutAttribute.leading, multiplier: DEFAULT_MULTIPLIER, constant: DEFAULT_PADDING)
let yconstraint = NSLayoutConstraint(item: item, attribute: NSLayoutAttribute.top, relatedBy: NSLayoutRelation.equal,
toItem: toItemY, attribute: NSLayoutAttribute.bottom, multiplier: DEFAULT_MULTIPLIER, constant: YPadding)
let widthConstraint = NSLayoutConstraint(item: item, attribute: NSLayoutAttribute.width, relatedBy: NSLayoutRelation.equal,
toItem: toItemXW, attribute: NSLayoutAttribute.width, multiplier: DEFAULT_MULTIPLIER, constant: 0)
return [xconstraint, yconstraint, widthConstraint]
}
将在其中的堆栈视图的其他函数。
stackview我使用该功能创建了一个电话号码文本链接，然后添加到动态生成的水平stackview中，并将其作为列表添加到垂直@IBOutlet weak var stackview: UIStackView!
var prevStackView = self.stackview
let phone_label = self.createLabelValue(text: "Phone")
let phone_num = self.createPhoneNumber(text: "800-199-1999")
// Faculty Phone
let phoneStackView = self.createStackView(subViews: [phone_label, phone], xpadding: CGFloat(8))
self.stackview.addSubview(phoneStackView)
let constraintsFacultyPhone = self.createConstraints(item: phoneStackView, toItemXW: self.scroll_view, toItemY: prevStackView ?? "", YPadding: CGFloat(2))
prevStackView = phoneStackView
self.scroll_view.addConstraints(constraintsFacultyPhone)
