Since it pageName

is a static string, this cannot be the reason for this.

So it has to be one of two things:



  • tab

    was not properly initialized before being passed to this method

  • method setTitle:

    to MSTabBarCollectionViewCell

    do something weird.

You will need to post more code (like how an object is initialized tab

and how the method that gets called is called) to get a more specific answer.

EXC_BAD_ACCESS means the instance class is not Execute. Check your pageName object. i think this is wrongly missed or Intialize
