使用 iPhone SDK 访问 iPhone 的通话记录 [英] Accessing the iPhone's Call log with the iPhone SDK

问题描述

我正在构建需要 iPhone 通话记录(只读)中的一些数据的应用程序.通话记录是一个位于/User/Library/CallHistory/call_history.db"的 sqlite 数据库.我使用越狱设备提取日志.但是，尝试使用 sqlite_open3() 命令打开此位置时，出现 SQLITE_ERROR 错误，根据库文档，该错误表示SQL 错误或缺少数据库".为了调试错误，我使用 NSFileManager 枚举文件夹('/User/Library/').它看起来好像正在返回一组过滤"的结果，其中排除了CallHistory"文件夹以及其他几个文件夹.

I am building application that required some data from iPhone's Call log(read only). The call log is a sqlite db located at "/User/Library/CallHistory/call_history.db". I used a jailbroken device to extract the log. However trying to open this location using the sqlite_open3() command I get a SQLITE_ERROR error, which according to the library documentation means "SQL error or missing database". In an attempt to debug the error I've used NSFileManager to enumerate the folder('/User/Library/'). It would appear as if it's returning a "filtered" set of results, that exclude the 'CallHistory' folder along with several of the other folders.

文件系统使用了一系列别名来给人一种传统OS X文件结构的错觉，不知道这些对我的结果有没有影响.

The File system uses a series of alias to give the illusion of tradition OS X file structure, and I don't know if these are having an effect on my results.

通话记录仅存在于设备上，而不存在于模拟器上.我一直无法让它在运行 Fireware 2.1 的第一代 iPhone 上运行.

The call log is only present on a device, and not the simulator. I've been unable to get it to work on a 1st gen iPhone running fireware 2.1.

这是我用来测试输出的一些代码

This is some code I used to test the output

NSDirectoryEnumerator *dirnum = [[NSFileManager defaultManager] enumeratorAtPath: @"/private/var/mobile/Library/"];

while( bar = [dirnum nextObject])
{
    //Uncomment if you don't want to log sub folders
    //[dirnum skipDescendents];

    NSLog(bar);
}

我怀疑 Apple 正在阻止对该目录的访问作为其沙盒策略的一部分，但现阶段我没有证据.但是，我可以毫无问题地访问地址簿，所以我有点困惑.

I have a suspicion that Apple is blocking access to the directory as part of its sandboxing strategy, however I have no proof at this stage. However, I can access the address book without any issues, so I'm a little confused.

谢谢

推荐答案

无法从 Cocoa Touch 或其他 iPhone API 访问通话记录.

There is no access to the call log from Cocoa Touch or other iPhone APIs.
