What is the best way to search for a string of text in a UIWebView?

回答1:

I think that the best to proceed is to:

1. Create a javascript function that will find your text
2. Use the stringByEvaluatingJavaScriptFromString: (see here) method to get the javascript code

3. Call the same method to look for the javascript function (put this code in a function that will take the aString argument):

   NSString *findThisStringFnc = [NSString stringWithFormat:@"findThisString('%@')",aString];
   [self stringByEvaluatingJavaScriptFromString:findThisStringFnc ];

4. Put all this code in a function (findAString for example) then call it from the UIWebView instance:
   [aWebView findAString:@"foobar"];
