前言 为什么不要在init和dealloc方法中调用getter和setter:Apple在Mac与iOS中关于内存管理的开发文档中,有一节的题目为:"Don'tUse Accessor Methods in Initializer Methods and dealloc",文中说:"Theonly places you shouldn't use accessor methods to set an instancevariable are in initializer m

这小节我们要介绍Go里面的流程控制以及函数操作. 流程控制 流程控制在编程语言中是最伟大的发明了,因为有了它,你可以通过很简单的流程描述来表达很复杂的逻辑.Go中流程控制分三大类:条件判断,循环控制和无条件跳转. if if也许是各种编程语言中最常见的了,它的语法概括起来就是:如果满足条件就做某事,否则做另一件事. Go里面if条件判断语句中不需要括号,如下代码所示 if x > 10 { fmt.Println("x is greater than 10") } els
