How get the return value of my block

I have a variable that is a block type with Bool return and void params. 

@property (nonatomic, copy) BOOL (^shouldDisplayView)(void);

I implement this block in another class of mine 

myClass.shouldDisplayView = ^BOOL(void) {
    return self->_count > 0;
};

I want to execute this block and check for the result, like:

if (result of shouldDisplayView is true) ...

Is it simply 

if (shouldDisplayView)

or is this checking if it's non-null?

if (myClass.shouldDisplayView)

will check shouldDisplayView isn't nil.

If you want to check result of shouldDisplayView is true, it should be

if (myClass.shouldDisplayView && myClass.shouldDisplayView())
