如何将SecIdentityRef添加到iOS密钥链，swift

我正在读取一个

p12

文件，并获得一个

SecIdentityRef

，然后将该身份添加到密钥链中，如下所示

let certData: NSData = NSFileManager.defaultManager().contentsAtPath(filePath)!
let passDictionary: NSMutableDictionary = NSMutableDictionary()
passDictionary.setValue("pass", forKey: kSecImportExportPassphrase as String)
print(kSecImportExportPassphrase as String)
var items: CFArray?
let error = SecPKCS12Import(certData, passDictionary, &items)
let unwrappedItems:CFArray = items!
if error == noErr && CFArrayGetCount(items) > 0 {
    let certChain = unwrappedItems as [AnyObject] as NSArray
    let certificateDict = certChain.objectAtIndex(0)
    var privateKeyRef : SecKeyRef? = nil
    var certificateRef: SecCertificate? = nil
    let secIdentity:SecIdentityRef = certificateDict.valueForKey(kSecImportItemIdentity as String) as! SecIdentityRef
    let subject:NSString=SecCertificateCopySubjectSummary(certificateRef!)

    let keyChainQuery:NSMutableDictionary = NSMutableDictionary(
        objects: [String(kSecClassIdentity),subject,kCFBooleanTrue,String(kSecAttrAccessibleAlwaysThisDeviceOnly),secIdentity],
        forKeys: [String(kSecClass),String(kSecAttrLabel), String(kSecAttrCanSign),String(kSecAttrAccessible),String(kSecValueRef)])
    let status:OSStatus = SecItemAdd(keyChainQuery as CFDictionaryRef, nil)
}

这似乎工作正常，并返回0作为状态代码，但当我尝试从钥匙链读取此项时：

var identity: AnyObject?
let searchQuery: NSMutableDictionary = NSMutableDictionary(objects: [String(kSecClassIdentity), kCFBooleanTrue], forKeys: [String(kSecClass),String(kSecReturnRef)])
let status:OSStatus = SecItemCopyMatching(searchQuery as CFDictionaryRef, &identity)

我在identity中收到一个-25300错误代码（未找到项）和

nil

，我正在使用

iOS 9.1

作为基本SDK，我做错了什么

---

更新：在8.1、8.4和9.1模拟器以及9.1真实设备中进行测试，代码正常工作。8.4.1版的iPhone出现了故障，有人知道发生了什么吗

最后，重新安装应用程序并使用SecItemDelete清理钥匙链解决了问题

希望这有帮助
