I have a couple viewcontrollers which are passing a variable between them using the appDelegate. example: User goes to tab 3 on TabBar, clicks a button, which puts them back into the Tab 1 with the data to be loaded into an existing Label.....I want it to auto update the label......Right now I have a button there IBAction Refresh, which updates the label once pressed....How can I avoid using the button, and just have it update?
Thank you.
Thank you.
