UIPickerView not properly interactive

[RobotWoods]

I have a small grouped table, most are text field edits, but two spawn pickers.

One is a single component list of names
One is a two component list of 0-9, and 0-.9
Both are populated the same way (nsmutablearray via componentsSeparatedByString)

The issue I'm having is a strange one about the areas of interactions.

On the first picker, the user can touch either the whitespace above the selector indicator bar, OR the area below, and move as they wish.

On the two component picker, the user can only spin the wheel by interacting with the area above the selector indicator bar. This is a bit problematic because the text (which I think is the natural place for the user to begin touching) is within the non-responsive area.

Both of the pickers are actually sitting on action sheets, but that portion of the code is a copy paste, so identical between them (aside from a name edit)

Any thoughts on elements to investigate? Does this sound familiar to anyone? Thanks for your help.

I double checked that all frames were the same just in case I was misaligning something...there is no difference between the working and non-working picker from that perspective.

I'm wondering if the short string length of each row (1 or 2 characters) is meaningful?

Thanks again.

Got it.

What I had not accounted for was that when the user selected fields on the lower portion of the screen, I would shift the view upwards. Since the action sheet frame was the same for both a shifted a non-shifted cell, only a part of the "touchable" area of the picker actually was aligned with the visible area of the picker.

What a mess.
