[英]tapgesture for textview string in swift
I have a signup page with privacy and term&condition. 我有一个包含隐私和条款及条件的注册页面。 I am using textview controller for show content when I was clicked any of them show another view controller, I tried this code but it's not working, 当我单击它们时,我正在使用textview控制器显示内容,其中任何一个都显示另一个视图控制器,我尝试了此代码,但无法正常工作,
let signUpTermsAndPrivacyString = NSMutableAttributedString(string: "I have read and understood PayGyft Terms of Usage and Privacy Policy",attributes: [NSAttributedStringKey.font: UIFont(name: "Helvetica", size: 15.0)!,NSAttributedStringKey(rawValue: NSAttributedStringKey.foregroundColor.rawValue): UIColor.darkGray])
let termsString = signUpTermsAndPrivacyString.mutableString.range(of: "Terms of Usage")
print("termsSTring",termsString)
signUpTermsAndPrivacyString.addAttribute(.link, value: "http://gregoryadunbar.com", range: termsString)
let privacyString = signUpTermsAndPrivacyString.mutableString.range(of: "Privacy Policy")
signUpTermsAndPrivacyString.addAttribute(.link, value:"http://gregoryadunbar.com", range: privacyString)
termsPrivacyPolicyTextView.attributedText = signUpTermsAndPrivacyString
func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
if (URL.absoluteString == termsURLString) {
print("termsURLString")
} else if (URL.absoluteString == privacyURLString) {
print("privacyURLString")
}
return false
}
You need to add myTextView.linkTextAttributes
您需要添加myTextView.linkTextAttributes
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center
let attributes = [NSAttributedStringKey.foregroundColor : UIColor.init(rgb: 0x646464),
NSAttributedStringKey.font : AppFont.getFont(fontType: .regular, ofSize: 16),
NSAttributedStringKey.paragraphStyle : paragraphStyle]
let attributedText = NSMutableAttributedString(string: descriptonText,
attributes: attributes)
if let range = attributedText.string.range(of: "terms & conditions") {
let nsRange = NSRange(range, in: attributedText.string)
attributedText.addAttributes([NSAttributedStringKey.link : "link://T&C"], range: nsRange)
}
let linkColor = UIColor.init(red: 47, green: 117, blue: 83)
let linkAttrs: [String: Any] = [NSAttributedStringKey.foregroundColor.rawValue : linkColor,
NSAttributedStringKey.underlineColor.rawValue : linkColor,
NSAttributedStringKey.underlineStyle.rawValue : NSUnderlineStyle.styleSingle.rawValue]
descriptionTextView.linkTextAttributes = linkAttrs
let textView = UITextView(frame: descriptionTextView.bounds)
textView.attributedText = attributedText
textView.layoutIfNeeded()
textView.sizeToFit()
let size = textView.sizeThatFits(CGSize(width: textView.frame.size.width, height: CGFloat.greatestFiniteMagnitude))
descriptionTextViewHeight.constant = size.height
descriptionTextView.attributedText = attributedText
And in delegate: 在代表中:
func textViewShouldBeginEditing(_ textView: UITextView) -> Bool {
return false
}
func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
return false
}
func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
debugPrint(URL.absoluteString)
if URL.absoluteString.contains("link://") {
// my func call
dismissAnimated()
}
return false
}
Also set isEditable to false and isSelectable to true. 还要将isEditable设置为false并将isSelectable设置为true。 Subclass textView and return false in canPerformAction
. 子类化textView并在canPerformAction
返回false。 In awakeFromNib
set textDragInteraction?.isEnabled = false
在awakeFromNib
设置textDragInteraction?.isEnabled = false
