I get the following error message when compiling:

2011-11-27 14:59:32.049 Storyboard[12104:f803] -[TargetViewController setPeople:]:unrecognized selector sent to instance 0x6d50310

terminate called throwing an exception

Funnily enough, my TargetViewController doesn’t even have a “people” property (NSMutableArray).

The structure of my app is that i have a tabbarcontroller with a tableView which got a detailView, and in the second tab a normal View (targetVieController) with a popover.

(As you might see I set up the whole thing with a storyboard, thats also the name of my app.

Fast help is appreciated!

EDIT

Maybe I should add that the compiler throws the error as soon as the app starts to load…

Following Michaels and MrMusic’s suggestions, I searched my Call stack for people and got this:

_cmd = SEL 0x6eae setPeople: (I reckon this is just a notice that there is the breakpoint)

And, surprisingly, i have an array that contains to “humans”, but they are not displayed in my tableview in the other tab.

    Search your project for “.people” and “setPeople” to see where that NSMutableArray collection is being set. Verify that you’re always setting people on the appropriate object (object that has the people property or a subclass of the object with the people property).

    Edit: something somewhere is trying to set the people collection. If searching for “.people” and “setPeople” literally returns nothing then perhaps something in IB or the StoryBoard is trying to set people. My original thought was some view controller incorrectly has type TargetViewController and is trying to set people (perhaps you’re saying myViewController.people = ... where myViewController is the wrong type.
