一、點(diǎn)擊到轉(zhuǎn)到網(wǎng)頁(yè)類(lèi)型

如下代碼：

    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"這是一段可點(diǎn)擊的文字，點(diǎn)擊百度去瀏覽網(wǎng)頁(yè)吧"];
    [attributedString addAttribute:NSLinkAttributeName
                             value:@"https://www.baidu.com"
                             range:[[attributedString string] rangeOfString:@"百度"]];
    [attributedString addAttribute:NSFontAttributeName
                             value:[UIFont systemFontOfSize:20]
                             range:NSMakeRange(0, attributedString.length)];
    self.textview.attributedText = attributedString;
    self.textview.linkTextAttributes = @{NSForegroundColorAttributeName: [UIColor blueColor], NSUnderlineColorAttributeName: [UIColor lightGrayColor],NSUnderlineStyleAttributeName: @(NSUnderlinePatternSolid)};

因?yàn)槭鞘褂胻extView來(lái)顯示的，所以要把textView的editable和scrollEnabled設(shè)置為NO.效果如下：

二、執(zhí)行自定義點(diǎn)擊事件類(lèi)型

    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"這是一段可點(diǎn)擊的文字呵恢，點(diǎn)擊百度去瀏覽網(wǎng)頁(yè)吧,當(dāng)然你也可以點(diǎn)擊自定義來(lái)執(zhí)行用戶(hù)事件！"];
    [attributedString addAttribute:NSLinkAttributeName
                             value:@"https://www.baidu.com"
                             range:[[attributedString string] rangeOfString:@"百度"]];
    [attributedString addAttribute:NSLinkAttributeName
                             value:@"CustomTapEvents://"
                             range:[[attributedString string] rangeOfString:@"自定義"]];
    [attributedString addAttribute:NSFontAttributeName
                             value:[UIFont systemFontOfSize:20]
                             range:NSMakeRange(0, attributedString.length)];
    self.textview.attributedText = attributedString;
    self.textview.linkTextAttributes = @{NSForegroundColorAttributeName: [UIColor blueColor],
                                          NSUnderlineColorAttributeName: [UIColor lightGrayColor],
                                          NSUnderlineStyleAttributeName: @(NSUnderlinePatternSolid)};

    self.textview.delegate = self;
    self.textview.editable = NO;
    self.textview.scrollEnabled = NO;

代理方法：

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
    if ([[URL scheme] isEqualToString:@"CustomTapEvents"]) {
        UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:@"用戶(hù)點(diǎn)擊了自定義事件" preferredStyle:UIAlertControllerStyleAlert];
        UIAlertAction *action = [UIAlertAction actionWithTitle:@"確定" style:UIAlertActionStyleCancel handler:nil];
        [alertController addAction:action];
        [self presentViewController:alertController animated:YES completion:nil];
        return NO;
    }
    return YES;
}
