Question

I have a Xcode project where I have to transfer Data from my SettingsViewController to my ViewController, the Problem is that I have to implement my SettingsViewController.h in my ViewController, because it gets pushed out of that – but to send data from the SettingsViewController to ViewController I have to implement the ViewController in SettingsViewcontroller too thats when the Program gets stuck – it’s not possible having a circular #import reference, isn´t it?

Answer 1

Use forward declaration in all the .h files then and import the files in .m files

A forward declaration looks like this:

@class SettingsViewController;
