You could try making your view controller implement the UISearchBarDelegate protocol and then implementing the searchBarShouldBeginEditing: method (by having it show your text fields + button, and returning NO).

The whole idea feels like a possible HIG violation, so proceed at your own risk if you're submitting to the App Store, as Apple could reject your app for behaving in a particularly non-standard way.
