关键代码

NSString *htmlString = [NSString stringWithFormat:@"在信息科技时代，秉持着“以创新科技立业，为客户创造价值，塑造品牌传播力”的理念，对外输出先进的移动端信息技术；如有疑问您可以访问https://www.baidu.com"];
                                                                                       
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:htmlString];
[attributedString addAttributes:@{NSUnderlineStyleAttributeName:@(NSUnderlineStyleSingle),NSLinkAttributeName:@""} range:NSMakeRange(5, 4)];
[attributedString addAttributes:@{NSLinkAttributeName:@""} range:NSMakeRange(27, 4)];
[attributedString addAttributes:@{NSUnderlineStyleAttributeName:@(NSUnderlineStyleSingle),NSLinkAttributeName:@"https://www.baidu.com"} range:NSMakeRange(62, 21)];
NSMutableParagraphStyle *style = [attributedString attribute:NSParagraphStyleAttributeName atIndex:0 effectiveRange:nil];
style.alignment = NSTextAlignmentLeft;
self.textView.attributedText = attributedString;
self.textView.font = [UIFont systemFontOfSize:17];

代理处理事件

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:    (NSRange)characterRange interaction:(UITextItemInteraction)interaction{
   NSLog(@"url:%@, %@", URL, NSStringFromRange(characterRange));

   return true;
}
