如何在越狱的iOS设备上快速从其捆绑ID获取应用程序的目录？

Question

在iOS设备中,所有用户应用程序都位于/var/mobile/Applications目录中,每个应用程序都有一个唯一的随机uuid作为其目录名称,例如:

/var/mobile/Applications/15FD62FD-2BEB-4C1E-A9B8-BC93E5C721CC

uuid是15FD62FD-2BEB-4C1E-A9B8-BC93E5C721CC.

现在我想通过应用程序的包标识符获取目录,我的解决方案是枚举/var/mobile/Applications目录,从中获取包标识符Info.plist并检查.

这个解决方案相当慢,有没有更快的方法呢？

例如,如果有一个plist将bundle id记录到uuid映射,那么我可以读取该文件以避免目录枚举.

我认为你要找的文件是

/var/mobile/Library/Caches/com.apple.mobile.installation.plist

例如,它包含每个应用程序的类似信息:

    "com.zillow.ZillowMap" =         {
        ApplicationDSID = 216284405;
        ApplicationType = User;
        CFBundleDisplayName = Zillow;
        CFBundleExecutable = ZillowMap;
        CFBundleIconFiles =             (
            "app-icon",
            "app-icon-iPad.png",
            "app-icon-iPad@2x.png"
        );
        CFBundleIcons =             {
            CFBundlePrimaryIcon =                 {
                CFBundleIconFiles =                     (
                    "app-icon",
                    "app-icon-iPad.png",
                    "app-icon-iPad@2x.png"
                );
                UIPrerenderedIcon = 1;
            };
        };
        CFBundleIdentifier = "com.zillow.ZillowMap";
        CFBundleName = ZillowMap;
        CFBundleShortVersionString = "6.1.0112";
        CFBundleVersion = "6.1.0112";
        CodeInfoIdentifier = "com.zillow.ZillowMap";
        Container = "/private/var/mobile/Applications/B9284FBE-E558-4A65-A7E4-AE20CDAD9A1D";
        Entitlements =             {
            "application-identifier" = "JEWMY3RZ4A.com.zillow.ZillowMap";
            "aps-environment" = production;
        };
        EnvironmentVariables =             {
            "CFFIXED_USER_HOME" = "/private/var/mobile/Applications/B9284FBE-E558-4A65-A7E4-AE20CDAD9A1D";
            HOME = "/private/var/mobile/Applications/B9284FBE-E558-4A65-A7E4-AE20CDAD9A1D";
            TMPDIR = "/private/var/mobile/Applications/B9284FBE-E558-4A65-A7E4-AE20CDAD9A1D/tmp";
        };
        IsUpgradeable = 1;
        LSRequiresIPhoneOS = 1;
        MinimumOSVersion = "5.0";
        Path = "/private/var/mobile/Applications/B9284FBE-E558-4A65-A7E4-AE20CDAD9A1D/ZillowMap.app";
        SequenceNumber = 2618;
        SignerIdentity = "Apple iPhone OS Application Signing";
        UIDeviceFamily =             (
            1,
            2
        );
        UIPrerenderedIcon = 1;
    };

更新

此文件已在iOS 8中删除:(https://www.theiphonewiki.com/wiki/Com.apple.mobile.installation.plist)

iOS 8中存在类似的文件/var/mobile/Library/MobileInstallation/LastLaunchServicesMap.plist,但它可能仅在启动时重新启动(重新启动).
