SecItemCopyMatching

返回一个或多个匹配查询搜索的 keychain 项目，或者拷贝指定 keychain 项目的属性。

声明：OSStatus SecItemCopyMatching ( CFDictionaryRef query, CFTypeRef *result );

此函数有两个参数：

query，包含一个项目类别的描述（Keychain Item Class and Values）和查找可选属性的字典。详见 Keychain Services Constants 对于当前定义的搜索属性的描述。

从 Xcode 6 开始，Apple 开始在标准架构中弃用 armv7s 架构，具体差异请看下图。

Xcode 5.1.1:

Xcode 6.1:

armv7s 架构指的是用于 iPhone 5 和 5C 等这些设备上的 A6 处理器。

在上一篇教程里，你学到了如何创建一个可复用的按钮控件。然而，对于开发者如何简单方便地来复用的话效果还不是非常明显。

一种共享它的方式就是直接提供源码文件。然而，这不是特别优雅。有可能你不想共享代码的实现细节。此外，开发者可能不想看见所有的东西，因为它们只是想继承一部分代码到自己的代码库里。

另一种方式是把你的代码编译成静态库来让开发者添加到他们的项目中去。然而这要求你来提供公共头文件，这样显得非常的笨拙。

你需要有一种简洁的方式来编译你的代码，并且它还要方便的共享和在多个项目间复用。你需要用什么方式来打包静态库并且它的头文件在一个文件里，然后只需要把这个文件添加到工程里就能立即开始使用。

	Returns a percent-escaped string following RFC 3986 for a query string key or value.
	RFC 3986 states that the following characters are "reserved" characters.
	- General Delimiters: ":", "#", "[", "]", "@", "?", "/"
	- Sub-Delimiters: "!", "$", "&", "'", "(", ")", "*", "+", ",", ";", "="

	In RFC 3986 - Section 3.4, it states that the "?" and "/" characters should not be escaped to allow
	query strings to include a URL. Therefore, all "reserved" characters with the exception of "?" and "/"
	should be percent-escaped in the query string.
	- parameter string: The string to be percent-escaped.
