问题描述

使用以下符号创建字符串时:

When creating a string using the following notation:

NSString *foo = @"Bar";

是否需要释放foo?还是foo在这种情况下会自动发布?

Does one need to release foo? Or is foo autoreleased in this case?

推荐答案

编译器分配的字符串(格式为@"STRING")是常量,因此-retain,-release和-autorelease消息将被忽略.在这种情况下,您不必释放或自动释放foo(但这不会造成伤害).

Compiler allocated strings (of the format @"STRING") are constant, and so -retain, -release, and -autorelease messages to them are ignored. You don't have to release or autorelease foo in this case (but it won't hurt).
