Think of a parent view controller that contains two children view controllers. The title of the parent view controller is a mixture of the titles of its children. The title of the second view controller depends on the name of its represented object too. Now, one would only need to bind the title of the window (for example) to the parent view con…
@interface ParentViewController : NSViewController
@property (strong, nonatomic) FirstChildViewController *firstViewController;
@property (strong, nonatomic) SecondChildViewController *secondViewController;
@end
@implementation ParentViewController

objc_msgSend cast
So:
id boxedValue = objc_msgSend(self, mappingSelector, instance, value, boxingParameters);
would become:
id boxedValue = ((id (*)(id, SEL, id, id, id))objc_msgSend)(self, mappingSelector, instance, value, boxingParameters);
The first `id` and `SEL` are basically `self` and `_cmd`, the first 2 arguments in any objc_msgSend.
