iphone - Getting dyld: Symbol not found: _UICollectionElementKindSectionFooter when trying to run my app in ipod touch? -


hello getting dyld: symbol not found: _uicollectionelementkindsectionfooter

when trying run app in ipod touch.

here xcode project setting - deployment target = 5.0. ipod touch os version = 5.1. ideas? project working on iphone 3gs ios 6.0.

uicollectionview class (and constants declared it) available starting ios 6.0 only, cannot use in older ios versions.

if still want support ios older 6.0 can use pstcollectionview library, copies uicollectionview functionality , interface + uses actual uicollectionview class when app being run on ios 6+
