创建新的持久性存储时崩溃（越狱的 iPhone 设备 4.1）

Question

每当我使用自签名证书将“CoreDataBooks”Apple iOS 示例应用程序部署到我的越狱设备并运行它时，它会在将核心数据持久存储添加到持久存储协调器的行崩溃：

第 178 行：

if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) {

// 更新以适当处理错误。 NSLog(@"未解决的错误 %@, %@", error, [error userInfo]); 中止（）； 同样有趣的是，

应用程序的“Document”目录从未创建，sqlite 也从未复制到其中，因此我怀疑它可能与写入权限问题有关。但是，我通过递归设置 777 权限来测试应用程序，结果是一样的。

示例与 iPhone 模拟器配合良好。

环境摘要：

• Xcode 3.2.4 / iOS SDK 4.1
• 设备：iPhone4 (iPhone3,1)
• 固件：4.1 (8B117)
• 越狱工具：PwnageTool 4.1.2

使用自签名证书进行代码签名，如 http://ihackmyi.com/forum/index.php/topic,24020.0.html

完整代码为从此位置下载：http://developer.apple.com/library/ios/#samplecode/CoreDataBooks/Introduction/Intro.html

出于构建目的，示例配置略有更改：

1. 基础 SDK：iOS 设备 4.1
2. 代码签名/任何 iPhone操作系统设备：“Xcode Code Sign”
3. iOS 部署目标：iOS 4.1

我使用 SSH 将其部署到设备上的 /Applications 目录，并将权限设置为 777：

iPhone:~ root# chmod -R 777 /Applications/CoreDataBooks.app

我使用 Respring 重新启动 Springboard，之后我运行 CoreDataBooks 应用程序，它崩溃了崩溃日志如下（我提供了符号化版本）：

Answer 1

只是猜测，但尝试手动创建文档目录。它因 abort() 而崩溃；当无法访问持久存储时会调用它。如果该目录不存在，则无法访问（即创建）它。

我认为文档目录是在定期安装应用程序时创建的。

或者尝试在开头的某个地方添加它：

NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
[[NSFileManager defaultManager] createDirectoryAtPath:path attributes:0];
