您将学到很多有关保留和释放变量的知识.通常，变量是根据作用域(即在何处使用)定义的.例如，您可能想初始化一个在viewDidLoad中整个类中使用的变量，然后在dealloc中释放它.这完全取决于您需要在哪里存储数据以及存储多长时间.

You'll learn a lot about retaining and releasing variables. In general variables are defined according to scope (i.e where they will be used) For example, you may want to initialize a variable that's used throughout a class in viewDidLoad and release it in dealloc. It all depends on where you need to store data and for how long.
