如果@protected是默认值，为什么这个ivar需要@protected？ [英] Why does this ivar need @protected if @protected is the default?

问题描述

@interface AClass : SomeType {
@protected
    NSMutableArray* amINotAlreadyProtected; //?
}

为什么此代码需要 @protected 如果 @protected 是默认值？这段代码是由一位非常有经验的程序员编写的，但我自己会省略说明符。

Why does this code need @protected if @protected is the default? This code was written by a very experienced programmer, but I would omit the specifier myself.

推荐答案

不需要用于关键字 @protected ，因为它是默认行为。

There is no need for the keyword @protected as it is the default behavior.

然而，一些程序员倾向于无论如何，请使用它，因为一个经验不足的程序员会在以后出现并且不知道这一点。还可以提到的是，它增加了代码的可读性，因为有些变量受到保护，而其他私有或公共变量。

However, some programmers tend to use it anyways incase a less experienced programmer comes along at a later date and doesn't know this. It can also be mentioned that it increase code readability incase there are some variables that are protected and other private or public.
