Unrecognized Selector with OHGridView

I downloaded the OHGridView hoping that it was the answer to all my problems.

https://github.com/AliSoftware/OHGridView

I did all that it said to do (add the class files, add the code, and change a few other things).

I went to build it and it crashed. I realized the lines of code why it was crashing:

((OHGridView *)self.view).rowHeight = 100;
((OHGridView *)self.view).columnsCount = 2;

Error from Console:

I removed them and it loaded fine but I didn't see any content.

Please help, thanks.

I did a clone of the repository just now and then did a build and run of his example project without making any changes to the code. It ran without any warnings or errors.

You'll need to check your code wherever you made changes.
update after your comment
Unrecognized Selector often means that you have a capitalization error or that your code isn't the kind of object that you think it is.
For example: I can get almost the same error that you get if I try to call the setRowHeight: directly against a OHGridView object instead of the view property of the object, like this

    ((OHGridView*)self).rowHeight = 100;
((OHGridView*)self).columnsCount = 2;

So, I would check your code to make sure that your object is an OHGridView and that you are setting the rowHeight property of the view of the OHGridView.
