ios - CYLTabBarController是怎么通过self.viewController访问该方法的？

Question

下面的方法不是getter方法吧，因为没有看到声明的变量

Answer 1

UITabBarController has an attribute called viewControllers. The following method is equivalent to overriding the getter method of the viewControllers attribute in UITabBarController. self.viewControllers calls the getter method of viewControllers

Answer 2

This is a feature of Objective-C or Xcode, self.view 等价于 [self view]
