  1. Your subclass of UIView should be capitalized to Tran for readability (class names are capitalized)
  2. You are adding m_view to the view controller's view via -addSubview:
  3. Therefore, the view controller view has a subviews array, and that array contains an object instance of type Tran *
  4. However, neither using -addSubview: nor casting via (Tran *) makes the view controller view of type Tran.
  5. The view controller's view is still of type UIView
  6. Therefore, you cannot call Tran's -doSomething on the view controller's view, because that view is not of type Tran
