segue PFObject unrecognized selector

Question

I'm getting an error, (see below), when I'm trying to pas a PFObject to a detailVC and press a cell in the tableView. As I see it I'm doing it right.

I'm loading the objects in the timeLineData Array and using a storyboard NavigationController. Also I use 2 querys to get the firstname and lastname in a UISearchBar.

+[PFObject parseClassName]: unrecognized selector sent to class

I've used a exception breakpoint to look for the error, it gives me this:

The error indicates you are sending parseClassName to the PFObject class. It's an instance method. Search your code for parseClassName. The error might be obvious when you see that code (if not, post it here). — danh, Jan 13 '15 at 20:00
possible duplicate of [How can I debug 'unrecognized selector sent to instance' error](http://stackoverflow.com/questions/25853947/how-can-i-debug-unrecognized-selector-sent-to-instance-error) — Hot Licks, Jan 13 '15 at 21:18
Thanks for the quick reply. I just don't understand what you mean with `sending parseClassName to PFObject class` I'm still a beginner with Parse. How should I look for parseClassName? I will update my `loadData` func. — SwingerDinger, Jan 13 '15 at 21:22
Has nothing really to do with Parse -- it's a fundamental concept of Objective-C. "Sending" a method to an object (as is done with `[someObject someMethodName]`) is essentially "calling" the method. You called a method that didn't exist (for that object class). — Hot Licks, Jan 13 '15 at 21:28
Thanks for the help guys. I've set an exception breakpoint to find out where the error came from. I've no clue what this mean, think it has something to with initialising the PFObject. See updated code above. — SwingerDinger, Jan 14 '15 at 08:44
Found the issue. I've init my persoondata the wrong way! had to use this `var persoonData:PFObject!` in DetailVC — SwingerDinger, Jan 14 '15 at 11:09

To solve this erros, you should implement these 2 methods in your subclass like this in .m file

+ (void)load
{
    [self registerSubclass];
}

+(NSString *)parseClassName
{
    return @"YOUR CLASS NAME HERE";
}

and then declare them in .h file like this

+(NSString *)parseClassName;
+(vendor *)createVendorWithObject:(PFObject *)object;

segue PFObject unrecognized selector
