Why did Apple not include radio buttons in Interface Builder?
<p>I realized that people have been implementing their own UIButton derivates to create radio buttons on iPhone, as <a href="http://www.mobisoftinfotech.com/blog/iphone/iphone-uibutton-tutorial-radio-buttons/" rel="nofollow">this blog post</a> and <a href="http://www.developers-life.com/radio-buttons-in-iphone-application.html" rel="nofollow">this one</a> show. </p>

<p>This <a href="http://stackoverflow.com/questions/662646/radio-button-in-iphone-app">question's accepted answer</a> states you can use <em>Picker Views</em> or <em>Grouped Table views with a check mark</em>, but it seems like a poor man's solution to me. Hence, my question: what is Apple's likely reasoning? </p>

<ul>
<li>Are radio buttons a bad UI solution for touch interfaces? </li>
<li>Is it so rarely used that it's not worth cluttering IB with?</li>
</ul>

<p>Another reason I don't quite see, maybe? I believe it's important to find this out, because if Apple thinks radio buttons suck, I'd rather not use them, and rethink my interface whenever I "believe" I should use one...</p>
