我无法在Mac Catalyst应用程序中写入/读取Keychain，它分别返回错误码34018和25300。有没有办法使Keychain在Catalyst应用程序中在Mac上工作？
Xcode: 11.0, MacOS: 10.15
这是一个示例代码，在iOS上运行正常，但在Mac上无法正常运行。该代码会打印“我的秘密蜜蜂”，以表示我们已成功将此文本写入Keychain并从中读取。
override func viewDidLoad() {
super.viewDidLoad()
let itemKey = "My key"
let itemValue = "My secretive bee "
deleteFromKeychain(itemKey: itemKey)
addToKeychain(itemKey: itemKey, itemValue: itemValue)
readFromKeychain(itemKey: itemKey)
}
func deleteFromKeychain(itemKey: String) {
let queryDelete: [String: AnyObject] = [
kSecClass as String: kSecClassGenericPassword,
kSecAttrAccount as String: itemKey as AnyObject,
]
let resultCodeDelete = SecItemDelete(queryDelete as CFDictionary)
if resultCodeDelete != noErr {
print("Error deleting from Keychain: \(resultCodeDelete)")
}
}
func addToKeychain(itemKey: String, itemValue: String) {
guard let valueData = itemValue.data(using: String.Encoding.utf8) else {
print("Error saving text to Keychain")
return
}
let queryAdd: [String: AnyObject] = [
kSecClass as String: kSecClassGenericPassword,
kSecAttrAccount as String: itemKey as AnyObject,
kSecValueData as String: valueData as AnyObject,
kSecAttrAccessible as String: kSecAttrAccessibleWhenUnlocked,
]
let resultCode = SecItemAdd(queryAdd as CFDictionary, nil)
if resultCode != noErr {
print("Error saving to Keychain: \(resultCode)")
}
}
func readFromKeychain(itemKey: String) {
let queryLoad: [String: AnyObject] = [
kSecClass as String: kSecClassGenericPassword,
kSecAttrAccount as String: itemKey as AnyObject,
kSecReturnData as String: kCFBooleanTrue,
kSecMatchLimit as String: kSecMatchLimitOne,
]
var result: AnyObject?
let resultCodeLoad = withUnsafeMutablePointer(to: &result) {
SecItemCopyMatching(queryLoad as CFDictionary, UnsafeMutablePointer($0))
}
if resultCodeLoad == noErr {
if let result = result as? Data,
let keyValue = NSString(data: result,
encoding: String.Encoding.utf8.rawValue) as? String {
// Found successfully
print(keyValue)
}
} else {
print("Error loading from Keychain: \(resultCodeLoad)")
}
}
