我有一个UITextView对象。 UIView中的文字有电话号码,邮件链接,网站链接。我想将它们显示为具有以下功能的链接。
当有人点击URL时 - Safari应该打开网站。 当有人点击电子邮件链接时 - 邮件应该打开我的地址到字段 当有人点击电话号码时 - 电话应用程序应拨打号码
以前是否有人这样做过或者知道如何处理它?</ p>
谢谢, AJ

如果您使用的是OS3.0
你可以像下面这样做
textview.editable = NO;
textview.dataDetectorTypes = UIDataDetectorTypeAll;

关于检测电子邮件地址的注意事项:必须安装邮件应用程序(它不在iOS模拟器上),以便电子邮件链接打开邮件撰写屏幕。
答案 2 :(得分:11)
从swift 3.0开始,如果您想以编程方式执行此操作,请使用以下代码。
textview.isEditable = false
textview.dataDetectorTypes = .all
或者如果你有故事板

虽然问题是超级老。 如果有人面临同样的问题,
它也可以用作 UILabel 。虽然 以下解决方案将完成这项工作: [不需要任何库..]
所以我使用了 MFMailcomposer()和 UITexView [代码在Swift 3.0中 - Xcode 8.3.2]
100%崩溃证明和工作代码处理所有角落案件。 = d
第1步。
import MessageUI
第2步。添加代理
class ViewController: UITextViewDelegate, MFMailComposeViewControllerDelegate{
第3步。从StoryBoard添加textView IBOutlet
@IBOutlet weak var infoTextView: UITextView!
第4步。在viewDidload()
中调用以下方法func addInfoToTextView() {
let attributedString = NSMutableAttributedString(string: "For further info call us on : \(phoneNumber)\nor mail us at : \(email)")
attributedString.addAttribute(NSLinkAttributeName, value: "tel://", range: NSRange(location: 30, length: 10))
attributedString.addAttribute(NSLinkAttributeName, value: "mailto:", range: NSRange(location: 57, length: 18))
self.infoTextView.attributedText = attributedString
self.infoTextView.linkTextAttributes = [NSForegroundColorAttributeName:UIColor.blue, NSUnderlineStyleAttributeName:NSNumber(value: 0)]
self.infoTextView.textColor = .white
self.infoTextView.textAlignment = .center
self.infoTextView.isEditable = false
self.infoTextView.dataDetectorTypes = UIDataDetectorTypes.all
self.infoTextView.delegate = self
}
第5步。实现TextView的委托方法
@available(iOS, deprecated: 10.0)
func textView(_ textView: UITextView, shouldInteractWith url: URL, in characterRange: NSRange) -> Bool {
if (url.scheme?.contains("mailto"))! && characterRange.location > 55{
openMFMail()
}
if (url.scheme?.contains("tel"))! && (characterRange.location > 29 && characterRange.location < 39){
callNumber()
}
return false
}
//For iOS 10
@available(iOS 10.0, *)
func textView(_ textView: UITextView, shouldInteractWith url: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
if (url.scheme?.contains("mailto"))! && characterRange.location > 55{
openMFMail()
}
if (url.scheme?.contains("tel"))! && (characterRange.location > 29 && characterRange.location < 39){
callNumber()
}
return false
}
第6步。编写帮助程序方法以打开MailComposer并调用应用程序
func callNumber() {
if let phoneCallURL = URL(string: "tel://\(phoneNumber)")
{
let application:UIApplication = UIApplication.shared
if (application.canOpenURL(phoneCallURL))
{
let alert = UIAlertController(title: "Call", message: "\(phoneNumber)", preferredStyle: UIAlertControllerStyle.alert)
if #available(iOS 10.0, *)
{
alert.addAction(UIAlertAction(title: "Call", style: .cancel, handler: { (UIAlertAction) in
application.open(phoneCallURL, options: [:], completionHandler: nil)
}))
}
else
{
alert.addAction(UIAlertAction(title: "Call", style: .cancel, handler: { (UIAlertAction) in
application.openURL(phoneCallURL)
}))
}
alert.addAction(UIAlertAction(title: "cancel", style: .default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
}
else
{
self.showAlert("Couldn't", message: "Call, cannot open Phone Screen")
}
}
func openMFMail(){
let mailComposer = MFMailComposeViewController()
mailComposer.mailComposeDelegate = self
mailComposer.setToRecipients(["\(email)"])
mailComposer.setSubject("Subject..")
mailComposer.setMessageBody("Please share your problem.", isHTML: false)
present(mailComposer, animated: true, completion: nil)
}
第7步。编写MFMailComposer的委托方法
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
switch result {
case .cancelled:
print("Mail cancelled")
case .saved:
print("Mail saved")
case .sent:
print("Mail sent")
case .failed:
print("Mail sent failure: \(String(describing: error?.localizedDescription))")
default:
break
}
controller.dismiss(animated: true, completion: nil)
}
你做完了...... = D

将以下属性设置为将其用作UILabel

我很好奇,您是否可以控制所显示的文字?如果是这样,你应该把它放在一个UIWebView中并在那里抛出一些链接,以“正确的方式”。
答案 5 :(得分:0)
步骤1.创建UITextview的子类并覆盖 canBecomeFirstResponder 功能
KDTextView.h代码:
@interface KDTextView : UITextView
@end
KDTextView.m代码:
#import "KDTextView.h"
// Textview to disable the selection options
@implementation KDTextView
- (BOOL)canBecomeFirstResponder {
return NO;
}
@end
步骤2.使用子类KDTextView
创建TextviewKDTextView*_textView = [[KDTextView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
[_textView setScrollEnabled:false];
[_textView setEditable:false];
_textView.delegate = self;
[_textView setDataDetectorTypes:UIDataDetectorTypeAll];
_textView.selectable = YES;
_textView.delaysContentTouches = NO;
_textView.userInteractionEnabled = YES;
[self.view addSubview:_textView];
第3步:实施委托方法
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange
{
return true;
}

Swift 4.2 Xcode 10.1
func setupContactUsTextView() {
let text = NSMutableAttributedString(string: "Love your App, but need more help? Text, Call (123) 456-1234 or email ")
if let font = UIFont(name: "Calibri", size: 17) {
text.addAttribute(NSAttributedStringKey.font,
value: font,
range: NSRange(location: 0, length: text.length))
} else {
text.addAttribute(NSAttributedStringKey.font,
value: UIFont.systemFont(ofSize: 17),
range: NSRange(location: 0, length: text.length))
}
text.addAttribute(NSAttributedStringKey.foregroundColor,
value: UIColor.init(red: 112/255, green: 112/255, blue: 112/255, alpha: 1.0),
range: NSRange(location: 0, length: text.length))
text.addAttribute(NSAttributedStringKey.link, value: "tel://", range: NSRange(location: 49, length: 15))
let interactableText = NSMutableAttributedString(string: "contact@abc.com")
if let font = UIFont(name: "Calibri", size: 17) {
interactableText.addAttribute(NSAttributedStringKey.font,
value: font,
range: NSRange(location: 0, length: interactableText.length))
} else {
interactableText.addAttribute(NSAttributedStringKey.font,
value: UIFont.systemFont(ofSize: 17),
range: NSRange(location: 0, length: interactableText.length))
}
interactableText.addAttribute(NSAttributedStringKey.link,
value: "contact@abc.com",
range: NSRange(location: 0, length: interactableText.length))
interactableText.addAttribute(NSAttributedStringKey.underlineStyle,
value: NSUnderlineStyle.styleSingle.rawValue,
range: NSRange(location: 0, length: interactableText.length))
text.append(interactableText)
videoDescTextView.attributedText = text
videoDescTextView.textAlignment = .center
videoDescTextView.isEditable = false
videoDescTextView.isSelectable = true
videoDescTextView.delegate = self
}
func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
if (characterRange.location > 48 && characterRange.location < 65){
print("open phone")
}else{
print("open gmail")
}
return false
}
步骤- 1.将委托设置为您的文本字段,不要忘记实现UITextViewDelegate 2.采取textView出口-@IBOutlet弱var videoDescTextView:UITextView! 3.添加上述两个功能。 此功能显示如何检测电话号码,来自textView的电子邮件,如何在电子邮件ID上加下划线,如何为文本赋予自定义颜色,自定义字体,在点击电话或电子邮件时如何调用功能等。
希望这可以帮助某人节省宝贵的时间。快乐编码:)
