IOS私有API的了解

IOS的API分为四种：

PublishedAPI(公开的API)（或者Documented API）

还有两类：私有API：PrivateAPI和未公开API：UnPublished API(或者UndocumentedAPI)。

私有API是指放在PrivateFrameworks框架中的API，未公开的API是指虽然放在Frameworks框架中，但是却没有在苹果的官方文档中有使用说明、代码介绍等记录的API。

按苹果的说法，未公开的API是还不够成熟，可能还会变动的API，等完全成型了后会变成公开的API，但是目前不对其提供承诺，就是系统版本升级后可能会失效。而私有API是苹果明确不能使用的API。虽然两者有所区别，但是在具体使用方法上是类似的。

私有API会面临审核通不过然后不能上线，但是也有使用私有API通过审核的比如谷歌的“GoogleVoice”，所以具体审核的详情不得而知。

示例一：

使用私有API——CoreTelephony获取本机号码

步骤如下：
1）导入CoreTelephony这个private framework
2）在xxx.m中加入红字部分：

#import "xxx.h"

extern NSString*CTSettingCopyMyPhoneNumb<wbr>er();<br></wbr>

@implementation
+(NSString *)myNumber{
return CTSettingCopyMyPhoneNumb<wbr>er();<br> }</wbr>
@end

3）在其它地方调用NSLog(@"myNumber=%@",[xxxmyNumber]);即是本机号码

另外机子的唯一标识码等一些信息可以用[UIDevice currentDevice]的uniqueIdentifier,name等属性来获取
