问题描述
在我的应用程序中,我有一个在 Xcode 6 中工作的 Keychain 访问类,但现在在 Xcode 6.1 中出现了一些错误,这是第一个错误:类型CFStringRef"不符合协议Hashable":
In my app i have a Keychain access class that was working in Xcode 6 but now in Xcode 6.1 i get some errors this is the first one: the Type 'CFStringRef' does not conform to protocol 'Hashable':
private class func updateData(value: NSData, forKey keyName: String) -> Bool {
let keychainQueryDictionary: NSMutableDictionary = self.setupKeychainQueryDictionaryForKey(keyName)
let updateDictionary = [kSecValueData:value] //HERE IS THE ERROR
// Update
let status: OSStatus = SecItemUpdate(keychainQueryDictionary, updateDictionary)
if status == errSecSuccess {
return true
} else {
return false
}
}
我也收到与第一个类似的错误,但它是:类型CFStringRef"不符合协议NSCopying"这里是我收到此错误的部分:
I also get a error similar to the the first one but it is: Type 'CFStringRef' does not conform to protocol 'NSCopying' here is the part where i get this error:
private class func setupKeychainQueryDictionaryForKey(keyName: String) -> NSMutableDictionary {
// Setup dictionary to access keychain and specify we are using a generic password (rather than a certificate, internet password, etc)
var keychainQueryDictionary: NSMutableDictionary = [kSecClass:kSecClassGenericPassword]
// HERE IS THE ERROR ↑↑↑
// Uniquely identify this keychain accessor
keychainQueryDictionary[kSecAttrService as String] = KeychainWrapper.serviceName
// Uniquely identify the account who will be accessing the keychain
var encodedIdentifier: NSData? = keyName.dataUsingEncoding(NSUTF8StringEncoding)
keychainQueryDictionary[kSecAttrGeneric as String] = encodedIdentifier
keychainQueryDictionary[kSecAttrAccount as String] = encodedIdentifier
return keychainQueryDictionary
}
谁能告诉我如何解决这些错误.
Can somebody tells me how to solve these error please.
推荐答案
CFStringRef
与 NSString
桥接,String
桥接.最简单的解决方案是将 kSecValueData
和 kSecClass
强制转换为 String
s 或 NSString
s:
CFStringRef
is bridged with NSString
which is bridged with String
. The simplest solution is to just cast kSecValueData
and kSecClass
to String
s or NSString
s:
这里:
let updateDictionary = [kSecValueData as String: value]
这里:
var keychainQueryDictionary: NSMutableDictionary = [kSecClass as NSString: kSecClassGenericPassword]
