i think you're mistaking gloss effect translucency that's allowing table show through tab bar. here's image showing 2 tabs:

it look content view showing through under tab bar, it's not showing through -- you're seeing glossy effect used draw tab items. illustrate, i'll change background color of content purple:

if content showing through tab bar, you'd see purple showing instead of white/gray can see there. see in own app, scroll table bit. if table showing through tab bar, able read content of next cell, including "9" , separator line. i'm sure won't see that, though.
