delaysContentTouches only on specific elements without subclassing?

I have a simple question. In my app, I have a some buttons for navigation inside a UIScrollView, which scroll with the content. This way, when the user enters a text field and the keyboard pops up, the buttons will scroll away for extra space. However, the buttons don't highlight immediately when I tap on them. I've learned that I can eliminate this problem by setting delaysContentTouches to NO, but this makes scrolling nearly impossible, because all the UITextFields and buttons in the view also highlight immediately, stealing the scroll.

I have found a way to only not delay the buttons via a UIScrollView subclass, so this is an option, but I was wondering if there is another way. I generally hate subclassing when it is to fix just one little thing.

The touchesShouldBegin:withEvent:inContentView: method of UIScrollView is intended to be overridden by subclasses if delaysContentTouches is set to YES. So this is the case when subclassing is completely OK.
