      NSString *policyPromptStr = @"I agree to the Terms of Use and Privacy Policy.";
    NSDictionary *attributes = @{NSForegroundColorAttributeName:[UIColor blackColor]};
    NSMutableAttributedString *attStr = [[NSMutableAttributedString alloc] initWithString:policyPromptStr attributes:attributes];
    [attStr addAttributes:@{NSForegroundColorAttributeName :[UIColor redColor],NSUnderlineStyleAttributeName:@(NSUnderlineStyleSingle),NSLinkAttributeName:@"Terms of Use"} range:NSMakeRange(15, 12)];
    [attStr addAttributes:@{NSForegroundColorAttributeName :[UIColor redColor],NSUnderlineStyleAttributeName:@(NSUnderlineStyleSingle),NSLinkAttributeName:@"Privacy Policy"} range:NSMakeRange(32, 14)];
    
    UITextView *policyTextView = [[UITextView alloc] initWithFrame:CGRectMake(20,100,260,30)];
    policyTextView.editable = NO;
    policyTextView.scrollEnabled = NO;
    policyTextView.attributedText = attStr;
    policyTextView.delegate = self;
    policyTextView.textContainerInset = UIEdgeInsetsMake(5, 0,0,0);
    [self.view addSubview:policyTextView];

代理里执行事件

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange{
    if (characterRange.location == 15 && characterRange.length == 12) {
       NSLog(@"Terms of use was clicked");
    }else if (characterRange.location == 32 && characterRange.length == 14){
        NSLog(@"Privacy Policy was clicked");
    }
    return NO;
}

返回yes的话并长按会crash
