Let's say we have the following classes: View @interface ArticleView : UIView @property IBOutlet UILabel *titleLabel; @property IBOutlet UILabel *bodyLabel; @end Model @interface Article : NSObject @property NSString *title; @property NSString *body; @end Controller @interface ArticleViewController : UIViewController @property Article *myArticle; @property ArticleView *myArticleView; - (void)displayArticle; @end @implementation - (void)displayArticle { // OPTION 1 myArticleView.titleLabel.text = myArticle.title; myArticleView.bodyLabel.text = myArticle.body; // ... or ... // OPTION 2 myArticleView.article = myArticle; } @end OPTION 1 PRO: Both the view and model aren't coupled to each other. CON: The controller needs to know the details of both the model and view. OPTION 2 PRO: The controller code is light and flexible (if the view or model change, the controller code stays the same. CON: The view and model are coupled and therefore less reusable. In OPTION 2, ArticleView will have to be changed to hold a reference to the model: @interface ArticleView : UIView @property IBOutlet UILabel *titleLabel; @property IBOutlet UILabel *bodyLabel; @property Article *article; @end The article setter can then be overwritten to update the view accordingly, like so: - (void)setArticle:(Article *)newArticle { _article = newArticle; self.titleLabel.text = _article.title; self.bodyLabel.text = _article.body; } So my question is, which one of these two options is best in terms of OO and iOS/MVC best practices?
