three20 p31 syntax error with UIAccessibilityTraits

Question

i downlaoded three20 p31. when i tried to build i got errors in following places

- (UIAccessibilityTraits) accessibilityTraits {
    return [super accessibilityTraits] | UIAccessibilityTraitStaticText; 
}

the same function is used in 3 classes. TTbutton.m,TTLabel.m,TTstyledTestlabel.m . i simply commented all funnctions containing UIAccessibilityTraits.Then my syantax errors got removed. i found out that in my UIkit framework there is no UIAccessibility.h file. is it my sdk problem ? Why UIAccessibility not included in my UIkit ?

Answer 1

What version of the iPhone SDK do you use and what version do you compile for? The accessibility traits were added in 3.0.
