问题
So I seem to be having some issues getting this value from the Keychain.
This is what I am using to save the password. This is called on the second view controller.
do {
try Locksmith.updateData(["password": "Boom123456"], forUserAccount: "KeychainDemo")
} catch {
print("Unable to set password")
}
When I go back to the first view controller that has the check for keychain item on:
let dictionary = Locksmith.loadDataForUserAccount("KeychainDemo")
if let passwordSaved = dictionary!["password"]?.stringValue {
print("password: \(passwordSaved)")
} else {
print("No Password")
}
When I run the app I get:
No Password
in the console. However, When I set break points on the let dictionary and then type po dictionary in the console I get this output:
Optional <Dictionary<String, AnyObject>>
Some : 1 elements
[0] : 2 elements
- .0 : "password"
- .1 : Boom123456
So it is there, Can anyone see why my code is not getting the password from the Keychain?
回答1:
Looks like you're pulling your "password" string out of the dictionary incorrectly. Don't use the .stringValue function in this case. Change this line:
if let passwordSaved = dictionary!["password"]?.stringValue {
to
if let passwordSaved = dictionary!["password"] as? String {
