iOS clickable text inside UITextView

问题

Is there a way to make clickable parts of UITextView. Actually I want to make text something like

By clicking “Register” above, you are agreeing to the Terms of Services and Privacy Statement

where Terms of Services should be one link and Privacy Statement another. And by clicking on those I should do something.

I did it with the code above using this project

- (void)_configureTermsLabel
{
    self.termsOfUseLabel.hidden = YES;
    self.termsAndConditionsLabel = [[TTTAttributedLabel alloc] initWithFrame:self.termsOfUseLabel.frame];
    self.termsAndConditionsLabel.font = [UIFont systemFontOfSize:14];
    self.termsAndConditionsLabel.lineBreakMode = UILineBreakModeWordWrap;
    self.termsAndConditionsLabel.numberOfLines = 0;

    NSString *termsStr = NSLocalizedString(@"Terms of use", @"Terms of use");
    NSString *privacyStr = NSLocalizedString(@"Privacy Policy", @"Privacy Policy");
    NSString *andStr = NSLocalizedString(@"and", @"and");
    NSString *conductStr = NSLocalizedString(@"Code of conduct", @"Code of conduct");
    NSString *termsAndConditionsStr = [NSString stringWithFormat:@"%@ - %@ %@ %@", termsStr,
                                       privacyStr, andStr, conductStr];
    self.termsAndConditionsLabel.text = termsAndConditionsStr;

    NSString *languageCode = [[GLQAppDelegate sharedDelegate] languageIdentifier];
    NSURL *termsURL = [NSURL URLWithString:[NSString stringWithFormat:kGLQTermsOfUseURL, languageCode]];
    NSURL *privacyURL = [NSURL URLWithString:[NSString stringWithFormat:kGLQPrivacyPolicyURL, languageCode]];
    NSURL *conductURL = [NSURL URLWithString:[NSString stringWithFormat:kGLQCodeOfConductURL, languageCode]];

    NSRange termsRange = [self.termsAndConditionsLabel.text rangeOfString:termsStr];
    NSRange privacyRange = [self.termsAndConditionsLabel.text rangeOfString:privacyStr];
    NSRange conductRange = [self.termsAndConditionsLabel.text rangeOfString:conductStr];

    [self.termsAndConditionsLabel addLinkToURL:termsURL withRange:termsRange];
    [self.termsAndConditionsLabel addLinkToURL:privacyURL withRange:privacyRange];
    [self.termsAndConditionsLabel addLinkToURL:conductURL withRange:conductRange];
    self.termsAndConditionsLabel.delegate = self;

    self.termsAndConditionsLabel.userInteractionEnabled = YES;
    [self.scrollView addSubview:self.termsAndConditionsLabel];
}
