Given the recent popularity of a few recent tutorials and the feedback / questions – I’ve opened up a simple forum so that people can discuss these tutorials and posts properly (instead of using comments). You can find the link for the discussion forums up at the top of the page or in the side bar.
Feel free to post comments in here as any future tutorials will not have commenting switched on – mainly to cure my OCD about posting tidyness!
Thanks for this great Tutorial.
I only need a question for a project I’m developing.
Is there a way to block the transition between two views?
In my project, I have a button setting in Storyboard to access to next view. At this button is linked an IBAction to do some check operations.
I want that if there is an error the transition to next view should not be run.
Is Possible?
Thanks
D.
You’d wire up your button to an IBAction method in your code and do the evaluation there first. If that evaluation is successful, then you’d use performSegueWithIdentifier: to force the transition.

p.s. Will have to discuss this in forum – I forgot to close comments on this post!
