当我尝试将Dictionary保存在NSUserDefaults中时，我找不到出现错误的原因。
有一个非常简单的类函数:
class func userLoggedIn(udid udid: String, username: String, email: String, userData: [String: AnyObject]) {
let userDataDictionary: NSDictionary = NSDictionary(dictionary: userData)
NSUserDefaults.standardUserDefaults().setObject(udid, forKey: UserDefaultsKeyType.UserUDID.rawValue)
NSUserDefaults.standardUserDefaults().setObject(username, forKey: UserDefaultsKeyType.Username.rawValue)
NSUserDefaults.standardUserDefaults().setObject(email, forKey: UserDefaultsKeyType.Email.rawValue)
NSUserDefaults.standardUserDefaults().setObject(userDataDictionary, forKey: UserDefaultsKeyType.UserData.rawValue)
NSUserDefaults.standardUserDefaults().synchronize()
}
它创建的记录很少是记录的用户数据。不幸的是.UserData key 有问题。过去的几行代码我试图在该键处保存userData对象。但是在错误之后，我添加了新的临时对象。在尝试保存一些新数据后，出现了该错误:

firstName = test;

name = test;
permissions = (
"test_user_role"
);
} as an NSUserDefaults/CFPreferences value for key userData

我会很高兴的帮助:)

您不能在其中存在null。
