iphone - Losing flicking functionality in picker view when iAd is up -


i have app has structure:

1) scroll view fills whole screen , 4 screens wide

2) 4 different uiviews fill scroll view pages, controlled page view controller.

3) main (first) scroll view has uipickerview exists @ bottom

4) in views 2-4 there iad window moves bottom when active, , moves down out of sight whene there no ad display. content above ad uitableview, shrinks automatically vacate space iad moves into. iad not move if scroll view on page 1 (as damage app functionality)

everything works, there strange bug:

when iad functionality enabled, 'flicking' functionality of uipickerview on page 1 doesn't work. still scrolls , selects fine, there no momentum wheels. move touch, touch ends wheels stop turning, without momentum typical of uipickerview wheel. if iad window not present (even if window off screen), flicking functionality works fine.

i have no freaking idea why happening.

and ideas?

screwed around , sort of fixed problem. have no idea why problem exists, worked around creating functions in top level view controller contains scroll view enable , disable scrolling function of scrollview. whenever first page displays picker, disables scrolling functionality, , re-enables when picker goes away. creates functionality looking , fixes original problem.

still not sure why problem existed in first place though!
