对于完全自定义的链接，你需要使用UIWebView -你可以拦截调用，这样当链接被按下时，你可以转到应用程序的其他部分。

用下面的.h和.m文件创建类。在.m文件中有以下函数

 - (void)linkAtPoint:(CGPoint)location

在这个函数中，我们将检查需要给予操作的子字符串的范围。使用你自己的逻辑来设置你的范围。

下面是子类的用法

TaggedLabel *label = [[TaggedLabel alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
[self.view addSubview:label];
label.numberOfLines = 0;
NSMutableAttributedString *attributtedString = [[NSMutableAttributedString alloc] initWithString : @"My name is @jjpp" attributes : @{ NSFontAttributeName : [UIFont systemFontOfSize:10],}];                                                                                                                                                                              
//Do not forget to add the font attribute.. else it wont work.. it is very important
[attributtedString addAttribute:NSForegroundColorAttributeName
                        value:[UIColor redColor]
                        range:NSMakeRange(11, 5)];//you can give this range inside the .m function mentioned above

下面是.h文件

#import <UIKit/UIKit.h>

@interface TaggedLabel : UILabel<NSLayoutManagerDelegate>

@property(nonatomic, strong)NSLayoutManager *layoutManager;
@property(nonatomic, strong)NSTextContainer *textContainer;
@property(nonatomic, strong)NSTextStorage *textStorage;
@property(nonatomic, strong)NSArray *tagsArray;
@property(readwrite, copy) tagTapped nameTagTapped;

@end   

下面是.m文件

#import "TaggedLabel.h"
@implementation TaggedLabel

  [self setupTextSystem];

 // Get the info for the touched link if there is one
 CGPoint touchLocation = [[touches anyObject] locationInView:self];
 [self linkAtPoint:touchLocation];
}

- (void)linkAtPoint:(CGPoint)location
{
 // Do nothing if we have no text
 if (_textStorage.string.length == 0)
 {
  return;
 }
 // Work out the offset of the text in the view
 CGPoint textOffset = [self calcGlyphsPositionInView];
 // Get the touch location and use text offset to convert to text cotainer coords
 location.x -= textOffset.x;
 location.y -= textOffset.y;
 NSUInteger touchedChar = [_layoutManager glyphIndexForPoint:location inTextContainer:_textContainer];

 // count it as a hit on the text
 NSRange lineRange;
 CGRect lineRect = [_layoutManager lineFragmentUsedRectForGlyphAtIndex:touchedChar effectiveRange:&lineRange];
 if (CGRectContainsPoint(lineRect, location) == NO)
 {
  return;
 }
 // Find the word that was touched and call the detection block
    NSRange range = NSMakeRange(11, 5);//for this example i'm hardcoding the range here. In a real scenario it should be iterated through an array for checking all the ranges
    if ((touchedChar >= range.location) && touchedChar < (range.location + range.length))
    {
     NSLog(@"range-->>%@",self.tagsArray[i][@"range"]);
    }
}

- (CGPoint)calcGlyphsPositionInView
{
 CGPoint textOffset = CGPointZero;
 CGRect textBounds = [_layoutManager usedRectForTextContainer:_textContainer];
 textBounds.size.width = ceil(textBounds.size.width);
 textBounds.size.height = ceil(textBounds.size.height);

 if (textBounds.size.height < self.bounds.size.height)
 {
  CGFloat paddingHeight = (self.bounds.size.height - textBounds.size.height) / 2.0;
  textOffset.y = paddingHeight;
 }

 if (textBounds.size.width < self.bounds.size.width)
 {
  CGFloat paddingHeight = (self.bounds.size.width - textBounds.size.width) / 2.0;
  textOffset.x = paddingHeight;

 return textOffset;
 }

我很难处理这件事…带有链接的UILabel在带属性的文本上…这只是一个头痛，所以我最终使用ZSWTappableLabel。

我扩展了@samwize的答案来处理多行UILabel，并给出了一个使用UIButton的例子

extension UITapGestureRecognizer {

    func didTapAttributedTextInButton(button: UIButton, inRange targetRange: NSRange) -> Bool {
        guard let label = button.titleLabel else { return false }
        return didTapAttributedTextInLabel(label, inRange: targetRange)
    }

    func didTapAttributedTextInLabel(label: UILabel, inRange targetRange: NSRange) -> Bool {
        // Create instances of NSLayoutManager, NSTextContainer and NSTextStorage
        let layoutManager = NSLayoutManager()
        let textContainer = NSTextContainer(size: CGSize.zero)
        let textStorage = NSTextStorage(attributedString: label.attributedText!)

        // Configure layoutManager and textStorage
        layoutManager.addTextContainer(textContainer)
        textStorage.addLayoutManager(layoutManager)

        // Configure textContainer
        textContainer.lineFragmentPadding = 0.0
        textContainer.lineBreakMode = label.lineBreakMode
        textContainer.maximumNumberOfLines = label.numberOfLines
        let labelSize = label.bounds.size
        textContainer.size = labelSize

        // Find the tapped character location and compare it to the specified range
        let locationOfTouchInLabel = self.locationInView(label)
        let textBoundingBox = layoutManager.usedRectForTextContainer(textContainer)
        let textContainerOffset = CGPointMake((labelSize.width - textBoundingBox.size.width) * 0.5 - textBoundingBox.origin.x,
                                              (labelSize.height - textBoundingBox.size.height) * 0.5 - textBoundingBox.origin.y);
        let locationOfTouchInTextContainer = CGPointMake((locationOfTouchInLabel.x - textContainerOffset.x),
                                                         0 );
        // Adjust for multiple lines of text
        let lineModifier = Int(ceil(locationOfTouchInLabel.y / label.font.lineHeight)) - 1
        let rightMostFirstLinePoint = CGPointMake(labelSize.width, 0)
        let charsPerLine = layoutManager.characterIndexForPoint(rightMostFirstLinePoint, inTextContainer: textContainer, fractionOfDistanceBetweenInsertionPoints: nil)

        let indexOfCharacter = layoutManager.characterIndexForPoint(locationOfTouchInTextContainer, inTextContainer: textContainer, fractionOfDistanceBetweenInsertionPoints: nil)
        let adjustedRange = indexOfCharacter + (lineModifier * charsPerLine)

        return NSLocationInRange(adjustedRange, targetRange)
    }

}

修改了@timbroder代码，以正确处理swift4.2的多行

extension UITapGestureRecognizer {

    func didTapAttributedTextInLabel(label: UILabel, inRange targetRange: NSRange) -> Bool {
        // Create instances of NSLayoutManager, NSTextContainer and NSTextStorage
        let layoutManager = NSLayoutManager()
        let textContainer = NSTextContainer(size: CGSize.zero)
        let textStorage = NSTextStorage(attributedString: label.attributedText!)

        // Configure layoutManager and textStorage
        layoutManager.addTextContainer(textContainer)
        textStorage.addLayoutManager(layoutManager)

        // Configure textContainer
        textContainer.lineFragmentPadding = 0.0
        textContainer.lineBreakMode = label.lineBreakMode
        textContainer.maximumNumberOfLines = label.numberOfLines
        let labelSize = label.bounds.size
        textContainer.size = labelSize

        // Find the tapped character location and compare it to the specified range
        let locationOfTouchInLabel = self.location(in: label)
        let textBoundingBox = layoutManager.usedRect(for: textContainer)
        let textContainerOffset = CGPoint(x: (labelSize.width - textBoundingBox.size.width) * 0.5 - textBoundingBox.origin.x,
                                          y: (labelSize.height - textBoundingBox.size.height) * 0.5 - textBoundingBox.origin.y);
        let locationOfTouchInTextContainer = CGPoint(x: (locationOfTouchInLabel.x - textContainerOffset.x),
                                                     y: 0 );
        // Adjust for multiple lines of text
        let lineModifier = Int(ceil(locationOfTouchInLabel.y / label.font.lineHeight)) - 1
        let rightMostFirstLinePoint = CGPoint(x: labelSize.width, y: 0)
        let charsPerLine = layoutManager.characterIndex(for: rightMostFirstLinePoint, in: textContainer, fractionOfDistanceBetweenInsertionPoints: nil)

        let indexOfCharacter = layoutManager.characterIndex(for: locationOfTouchInTextContainer, in: textContainer, fractionOfDistanceBetweenInsertionPoints: nil)
        let adjustedRange = indexOfCharacter + (lineModifier * charsPerLine)
        var newTargetRange = targetRange
        if lineModifier > 0 {
            newTargetRange.location = targetRange.location+(lineModifier*Int(ceil(locationOfTouchInLabel.y)))
        }
        return NSLocationInRange(adjustedRange, newTargetRange)
    }
}

UILabel代码

let tapAction = UITapGestureRecognizer(target: self, action: #selector(self.tapLabel(gesture:)))

let quote = "For full details please see our privacy policy and cookie policy."
let attributedString = NSMutableAttributedString(string: quote)

let string1: String = "privacy policy", string2: String = "cookie policy"

// privacy policy
let rangeString1 = quote.range(of: string1)!
let indexString1: Int = quote.distance(from: quote.startIndex, to: rangeString1.lowerBound)
attributedString.addAttributes(
            [.font: <UIfont>,
             .foregroundColor: <UI Color>,
             .underlineStyle: 0, .underlineColor:UIColor.clear
        ], range: NSRange(location: indexString1, length: string1.count));

// cookie policy
let rangeString2 = quote.range(of: string2)!
let indexString2: Int = quote.distance(from: quote.startIndex, to: rangeString2.lowerBound )

attributedString.addAttributes(
            [.font: <UIfont>,
             .foregroundColor: <UI Color>,
             .underlineStyle: 0, .underlineColor:UIColor.clear
        ], range: NSRange(location: indexString2, length: string2.count));

let label = UILabel()
label.frame = CGRect(x: 20, y: 200, width: 375, height: 100)
label.isUserInteractionEnabled = true
label.addGestureRecognizer(tapAction)
label.attributedText = attributedString

编码来识别水龙头

 @objc
  func tapLabel(gesture: UITapGestureRecognizer) {
     if gesture.didTapAttributedTextInLabel(label: <UILabel>, inRange: termsLabelRange {
            print("Terms of service")
     } else if gesture.didTapAttributedTextInLabel(label:<UILabel> inRange: privacyPolicyLabelRange) {
            print("Privacy policy")
     } else {
            print("Tapped none")
     }
    }
