问题描述

如何在Xcode 4中为可执行文件设置NSZombieEnabled和CFZombieLevel?

How do I set up NSZombieEnabled and CFZombieLevel for my executable in Xcode 4?

推荐答案

在Xcode 4.x中按

In Xcode 4.x press

(或单击Menubar> Product> Scheme> Edit Scheme)

(or click Menubar > Product > Scheme > Edit Scheme)

选择诊断"标签，然后单击启用僵尸对象":

select the "Diagnostics" tab and click "Enable Zombie Objects":

这会将释放的对象转换为NSZombie实例，并在再次使用时打印控制台警告.这是一个调试辅助工具，可以增加内存使用量(实际上没有释放任何对象)，但可以改善错误报告.

This turns released objects into NSZombie instances that print console warnings when used again. This is a debugging aid that increases memory use (no object is really released) but improves error reporting.

一种典型的情况是，当您过度释放一个对象却不知道是哪个对象时:

A typical case is when you over-release an object and you don't know which one:

• 有僵尸:-[UITableView release]: message sent to deallocated instance
• 没有僵尸:

当您存档应用程序以提交App Store时，将忽略此Xcode设置.在发布应用程序之前，您无需触摸任何东西.

This Xcode setting is ignored when you archive the application for App Store submission. You don't need to touch anything before releasing your application.

在按住 Alt 键的同时，按⌥ selecting R 等同于选择产品">运行".
单击启用僵尸对象"复选框与在参数"选项卡的环境变量"部分中手动添加"NSZombieEnabled = YES"相同.

Pressing ⌥⌘R is the same as selecting Product > Run while keeping the Alt key pressed.
Clicking the "Enable Zombie Objects" checkbox is the same as manually adding "NSZombieEnabled = YES" in the section "Environment Variables" of the tab Arguments.
