I have some text which might or might not contain web URLs, phone numbers, email links etc. which UIWebView automatically detects as hotspots.
我有一些文本，可能或可能不包含web url、电话号码、电子邮件链接等，UIWebView自动检测为热点。
Question: I want to show this text in UIWebView ONLY when there are one or more hotspots, but as plain text if it doesn't. So how can I detect this in code?
问题:我想在UIWebView中只有一个或多个热点的时候显示这个文本，但是如果没有，就像纯文本一样。那么我如何在代码中检测到这个呢?
Additional Info: JavaScript code below tells how many <a href="...">...</a> links there are. This does NOT count how many other "link" items there are. For example "Link to www.yle.fi" contains one link according to UIWebView, but zero according to JavaScript:
附加信息:下面的JavaScript代码告诉我们有多少
NSString *s = [webView stringByEvaluatingJavaScriptFromString:
@"document.links.length"];
Still no answer to the question how to ask UIWebView how many links it has found...
仍然没有回答如何问UIWebView它找到了多少链接…

You can use several regular expressions and check if the text matches those of URL/phone number/email addresses.
您可以使用几个正则表达式，并检查文本是否与URL/电话号码/电子邮件地址相匹配。
However, if your intention is simply let the user open a link, the UITextView is suffice.
但是，如果您的意图只是让用户打开一个链接，那么UITextView就足够了。
