问题
I'm wanting to create a read only text area in my app which allows the user to click on any word and the app reads it out. I am however a little confused on which method would be the best. I see two options, use a UILabel and create some method to detect the region clicked then match it to the word in that region but it sounds hard to implement. On the other hand I could use an array of words to create a list of UIbutton's. Any advice and/or sample code to help me would be much appreciated, thanks Jason.
Note: Each view has about 30 words on it.
The solution below works well. For anyone else wanting to use this, these four lines will set your UIWebView to have a clear background and disable any scrolling or bounce.
[[myWebView.subviews objectAtIndex:0] setScrollEnabled:NO];
[[myWebView.subviews objectAtIndex:0] setBounces:NO];
[myWebView setBackgroundColor:[UIColor clearColor]];
[myWebView setOpaque:NO];
And some handy css to stop the open popup when a user presses and holds a link.
*{-webkit-touch-callout:none; -webkit-user-select: none;}

How big is your text area? If it's big then creating a UIButton for each work sounds like sa bit of effor to get the text to layout correctly.
I would use a UIWebView - make each word like this :
<a href="wordpress://WORD1">WORD1</a> <a href="wordpress://WORD2">WORD2</a> <a href="wordpress://WORD3">WORD3</a>
and attach your view controller as the webView's UIWebViewDelegate delegate.
Then, you can intercept presses on each word using the webView:shouldStartLoadWithRequest:navigationType: delegate method :)
