我有一个UITextView对象。在UIView的文本具有一个电话号码,电子邮件链接,网站链接。我想向他们展示与以下功能的链接。
当有人对URL水龙头 - Safari浏览器应打开该网站。当有人在电子邮件中的链接水龙头 - 邮件应该在外地,我的地址打开,当有人在电话号码水龙头 - 电话申请应拨打该号码
有没有人这样做过或知道如何处理呢?
谢谢,AJ
如果您使用的OS3.0
你可以像下面
textview.editable = NO;
textview.dataDetectorTypes = UIDataDetectorTypeAll;
必须安装邮件应用程序(它不是在iOS模拟器)的电子邮件中的链接打开邮件撰写屏幕:在检测到的电子邮件地址的说明。
虽然问题是超级老。不过,如果任何人面临着同样的问题,
此外,它可以作为一个UILabel。虽然下面的解决方案将做的工作:没有一个不需要任何库..]
所以我用MFMailcomposer()和UITexView [代码为雨燕3.0 - Xcode的8.3.2]
100%防崩溃,以及工作守则处理所有角落的情况。 = d
第1步。
import MessageUI
第2步:添加委托
class ViewController: UITextViewDelegate, MFMailComposeViewControllerDelegate{
第3步:添加TextView的IBOutlet中从故事板中
@IBOutlet weak var infoTextView: UITextView!
第4步:呼叫在viewDidLoad中下面的方法()
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:实施委托方法的TextView
@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:写辅助方法来打开MailComposer和呼叫应用
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: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)
}
这就是它,你就大功告成了... = d
下面是上面的代码迅速文件:textViewWithEmailAndPhone.swift
将下面的属性把它当作一个UILabel
我很好奇,你有没有显示在文本上的控制?如果是这样,你应该只是坚持在一个UIWebView并扔在那里的一些环节做“正确的方式”。
步骤1.创建的UITextView的子类,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
第2步:使用子类KDTextView创建的TextView
KDTextView*_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];
步骤3:实施委托方法
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange
{
return true;
}
