使用XIB和插座加载自定义UIView的最佳策略

Question

What is best strategy to load custom UIView s with XIB and Outlets? At this moment I have code listed below. I think this code is bad because I have 2 UIViews as container and in future probably problem with constraints.

• UIViewController ( I don't want all outlets and actions in one big ViewController )

   func showCategories() { if(self.categoriesView == nil) { self.categoriesView = CategoriesView() } self.view.addSubview(self.categoriesView!) } 

• Custom UIView - CategoriesView

   class CategoriesView, ...protocols... { @IBOutlet var table:UITableView! override init(coder aDecoder: NSCoder) { super.init(coder: aDecoder) } override init(frame:CGRect) { super.init(frame: frame) } override init() { super.init() let views = NSBundle.mainBundle().loadNibNamed("CategoriesView", owner: self, options: nil) let view = views![0] as CategoriesView self.frame = view.frame self.addSubview(view) } .... }

In Apple's MVC, it's best to avoid views with too much logic in them. If you want to compose a complex view using component subviews, then look at Creating Custom Container View Controllers .

If you are already using storyboards, a container view will take care of most of the complexity for your.
