ios - iOS7 and iOS8 segue.destinationViewController -

i'm trying make app work both ios7 , ios8 , ran problem in prepareforsegue methods in view controllers.

in ios8 segue.destinationviewcontroller of class uinavigationcontroller, use [[segue.desinationviewcontroller viewcontrollers] objectatindex:0] works fine, in ios7 segue.desinationviewcontroller of class cmamyviewcontrollerclassname, throw error when try send viewcontollers message it.

i found this solution work, wondering if there's better solution? other latter post haven't been able find it. if there's not "proper" solution, i'll create method gets correct view controller; wondering how other people handled situation.

thanks!

this issue resolved checking class of destination view controller before trying access 1 of properties:

- (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender {     destcontroller *vc = segue.destinationviewcontroller;      if ([dvc iskindofclass:[destcontroller class]])         dvc.propertyname = @"property value";     else         // else } 

taken solution in this thread.
