I have a button and would like to know its enabled state while stepping through code. This doesn't work in the debugger:
po self.myButton.enabled
It prints:
There is no member named enabled.
Is there another way to print out its state?

A:
gdb doesn't know dot-syntax for properties, but it will evaluate method calls. -[UIButton enabled] returns a BOOL, which is a scalar type, not an object, so you should use p with a type cast, like this:
p (BOOL)[[self myButton] enabled]
If the property you want to inspect is an object, you can use po without the type cast, like this:
po [[self myButton] font]

I keep getting the same message: Target does not respond to this message selector.

Aha. The UIControl documentation declares the enabled property as "@property(nonatomic, getter=isEnabled) BOOL enabled". It doesn't use the default getter method. So try "p (BOOL)[[self myButton] isEnabled]".
