IOS UIAlertController 超链接 HTML

问题：

                向html" class="superseo">UIAlertController 添加超链接怎么办？

解决：

[mUIAlertController setValue:viewController forKey:@"contentViewController"];

最终通过替换contentViewController，暂时解决。

 UIAlertController* mUIAlertController = [UIAlertController alertControllerWithTitle:@"用户须知"
                                                                               message:@"" preferredStyle:UIAlertControllerStyleAlert];

NSMutableParagraphStyle *paraStyle = [[NSMutableParagraphStyle alloc] init];
            paraStyle.alignment = NSTextAlignmentLeft;

            NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:message attributes:@{NSParagraphStyleAttributeName:paraStyle,NSFontAttributeName:[UIFont systemFontOfSize:14.0]}];
            [attributedString addAttribute:NSLinkAttributeName value:@"agreement://" range:[[attributedString string] rangeOfString:@"《用户协议》"]];
            [attributedString addAttribute:NSLinkAttributeName value:@"policy://" range:[[attributedString string] rangeOfString:@"《隐私政策》"]];


            UIViewController *viewController = [[UIViewController alloc]init];
            PHTTextView *textView = [[PHTTextView alloc]initWithFrame:CGRectMake(10, 0, 250,100)];
            textView.attributedText =attributedString;
            textView.editable = NO;
          
            textView.scrollEnabled = YES;
            textView.backgroundColor = [UIColor clearColor];
            textView.delegate =self;

            [viewController.view addSubview:textView];

            [mUIAlertController setValue:viewController forKey:@"contentViewController"];

UITextView实现UITextViewDelegate接口，在(BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange interaction:(UITextItemInteraction)interaction，方法中做相关点击处理

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange interaction:(UITextItemInteraction)interaction{
 
    if ([[URL scheme] isEqualToString:@"agreement"]) {
        PrivacyAgreementViewController* orderVc = [PrivacyAgreementViewController new];
        orderVc.name = @"xxx_user_agreement";
        [self.navigationController pushViewController:orderVc animated:YES];
//        [self dismissViewControllerAnimated:YES completion:nil];
        return NO;
    }else if ([[URL scheme] isEqualToString:@"policy"]) {
        PrivacyAgreementViewController* orderVc = [PrivacyAgreementViewController new];
        orderVc.name = @"xxx_policy";
        [self.navigationController pushViewController:orderVc animated:YES];
//        [self dismissViewControllerAnimated:YES completion:nil];
        return NO;
    }
    return YES;
}
