I randomly get this error, and I can't figure out a way to fix it: the variables pane (top right) is blank, and the gdb "po" command can't print any variables.

Does selectRow:inComponent:animated: cause pickerView:didSelectRow:inComponent: to fire?

I'm getting some strange behaviour, and I'm wondering if a root cause of that behaviour might be selectRow (used to set which row in the picker wheel should be viewed as selected) causing didSelectRow (which I thought was only used for user input) to fire. I certainly can't come up with any other reason for code that should only be in d...

I have been working on a horizontal UIPicker, and I've finally gotten the picker and the labels on the picker to both display rotated.
