iOS钥匙串：找不到值

Question

I write something into the keychain on a device with an older version of my project; then, I'd like to restore it with a new version - but I don't get any value back.

I'm doing the exact same thing, I use the same provisioning profile, bundle identifier... What could be the reason for not getting a value back with my newer project version? The query is the exact same one (using SFHFKeychainUtils):

(NSMutableDictionary *) $17 = 0x00982fd0 {
    acct = "com.abc.def.ghi.jkl.1";
    class = genp;
    svce = "SOME-THING";
}

我认为SFHFKeychainUtils与codesign证书相关联，您应该再次检查代码签名的标识和设置配置文件。
