I’ve a tabbar based app. And on each VC (tab) I have a JSON service call. What’s the best way to preload all the views on the tabs, so when users tap on the tab, it is already loaded? Is there any method to make a view load?
Tks!

The best way is to follow the MVC design pattern and make the service calls independent of the UI. When you app launches start loading all (using a singleton class or an instance of your “
