Enum Type variable BAD_ACCESS

Question

I ran into this issue:

I defined a enum type in the header file:

typedef enum {
    aView,
    bView,
    cView
} SCViewType;

and then in my header file, I have:

@property (nonatomic) SCViewType currentView;

In my .m file, I have this:

- (void) setCurrentView: (SCViewType) view
{
    self.currentView = view;
}

And this self.currentView = view line got BAD_ACCESS error...

Please point me what's wrong with this implementation, and what I should do to fix it?

Thank you!

Is that all you do in your `setCurrentView:` method? If so, why override the synthesized setter method for the property? — rmaddy, Jul 29 '14 at 03:41

When you call self.currentView = view;. Objective-C will convert to - (void) setCurrentView: (SCViewType) view automatically. So this method will be called again and again.

Just modify the code to:

- (void) setCurrentView: (SCViewType) view
{
    _currentView = view;
}

Keep in mind that of the OP also implements the getter method, the ivar won't exist unless it is added explicitly. – rmaddy Jul 29 '14 at 03:41

The "self." will call the the setter method and end up in endless loop. More detail
