请教一下各位朋友，就是ipa程序安装怎么实现的啊？ 我在网上找了一个方法 typedef int (*MobileInstallationInstall)(NSString *path, NSDictionary *dict, void *na, NSString *path2_equal_path_maybe_no_use);

• (int)IPAInstall:(NSString *)path

{

void *lib = dlopen("/System/Library/PrivateFrameworks/MobileInstallation.framework/MobileInstallation", RTLD_LAZY);

if (lib)

{

    MobileInstallationInstall pMobileInstallationInstall = (MobileInstallationInstall)dlsym(lib, "MobileInstallationInstall");

    if (pMobileInstallationInstall)

    {

        int ret = pMobileInstallationInstall(path, [NSDictionary dictionaryWithObject:@"User" forKey:@"ApplicationType"], nil, path);

        dlclose(lib);

        return ret;

    }

}

return -1;

}

，这个我在模拟器上能够安装成功，在真机上返回-1，安装失败 路径也绝对正确，求帮助啊
