iOS：在哪里可以找到iOS的OSStatus代码的完整列表？ [英] iOS: Where to find the full list of OSStatus codes for iOS?

问题描述

我可以在OS X库源代码中轻松找到 noErr = 0 。但是很难在iOS上找到 OSStatus 的完整错误代码列表。

在Mac OS X上，找到类似

不是那么难。

  kAudioHardwareUnsupportedOperationError 
  

但是我似乎找不到iOS OSStatus代码的有用信息。

谢谢！

更新：

我不认为我的问题与上述问题重复。 可能的重复问题的操作想将他已经知道的4字符代码转换为人类可读的字符串。相反，这是我的进一步规格：

我甚至不知道什么4字符或typedefed整数用于iOS。
我想看到像一个完整的代码列表，就像你通常会在许多C ++框架/库设计中看到的，例如枚举列表或标准异常，甚至OSX k-something代码，这至少可以在Xcode文档中找到。

这些代码的用法包括：

我的自定义函数，例如，一些CoreAudio回调必须返回OSStatus，我想返回这些内置的人工可读代码来指示运行时错误的类型。没有列表，我不知道什么返回，除了noErr。

很显然，许多OSX k代码在iOS环境下是未定义的，因此他们不能

UPDATE（CONCLUSION）： ：在Xcode文档（管理器）中搜索关键字结果代码，我们在系统指南结果中得到或多或少的归类代码文档部分。这对我原来的问题是够好的。 -

解决方案

我可以做的最好的帮助是提供使用 find 从命令行：

  $ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform /Developer/SDKs/iPhoneOS6.1.sdk 
 $ find。 -name \ * .h -exec fgrep -l OSStatus {} \;

I can easily find noErr = 0 in the OS X library source code. But it's pretty hard to find a full list of error code for OSStatus on iOS.

On Mac OS X, it's not that hard to find stuff like

kAudioHardwareUnsupportedOperationError

But I can't seem to find useful info for iOS OSStatus codes. It would be nice to have a full list of them or any pointers to the header files that define them.

Thanks!

UPDATE:

I don't think my question is a duplicate of the above question. The op of that "possible duplicate" question wanted to convert the 4-char codes he already knew into human-readable strings. Instead, here is my further spec:

I don't even know what 4-char or typedefed integers to use for iOS. I'd like to see something like a full list of codes, like you would normally see in many C++ framework/library design, e.g., an enum list, or standard exceptions, or even the OSX k-something codes, which at least can be found in the Xcode docs alone.

My usecases of these codes include:

In my custom functions, e.g., some CoreAudio callbacks that have to return OSStatus, I'd like to return these built-in human-readable codes to indicate the types of runtime errors. Without the list, I don't know what to return, other than noErr.

Apparently, many OSX k-codes are undefined under iOS environment so they can't be used transparently.

UPDATE (CONCLUSION):

I finally found a clue: Search for keyword "Result Codes" in Xcode documentation (Organizer) and we get more or less categorized return codes documentation sections in the "System Guides" result. This is good enough for my original question. –
