Comments
  • which version of iOS sdk you using?
  • it just changes selected icon it tab bar but it doesn't change view.
  • @HorheGarcia is the icon changed to correct. if the icon and the tab index is right, check the selected view controller. Does you tap the tab index, it behaves right?
  • i found the problem, my tab tab is situated in another controller. From that controller it works ok, how can i access it from another controller?
  • @HorheGarcia use delegation pattern to interact between controllers
  • it just changes selected icon it tab bar but it doesn't change view.
  • If the tab bar icon is changing it sounds like it IS changing the view controller - are you sure the views in your tab bar are distinct enough to recognise them changing?

  • its best if you refer to Tabster, included with ios documentation. there must be something you are doing wrong.
