ios - 无法在 Swift2.0 中调用类型 'NSDictionary' 的初始值设定项

Question

这可能很简单，但是，由于我对 Swift 的经验不是很丰富，所以我不知道如何将此行移植到 Swift 2.0。

func setPasscode(identifier: String, passcode: String) {
    var dataFromString: NSData = passcode.dataUsingEncoding(NSUTF8StringEncoding)!;

    var keychainQuery = NSDictionary(objects: [kSecClassGenericPassword, identifier, dataFromString], forKeys: [kSecClass, kSecAttrService, kSecValueData])

    SecItemDelete(keychainQuery as CFDictionaryRef);
    var status: OSStatus = SecItemAdd(keychainQuery as CFDictionaryRef, nil);
}

错误信息:无法使用类型为“(objects: NSArray, forKeys: [CFString])”的参数列表调用类型“NSDictionary”的初始值设定项

Answer 1

let identifier = "someIdentifier"
let dataFromString = "someData"
let values = [kSecClassGenericPassword, identifier, dataFromString]
let keys: [NSString] = [kSecClass, kSecAttrService, kSecValueData]
let keychainQuery = NSDictionary(objects: values, forKeys: keys)
