Keychain-iOS-ObjC is a simple Objective-C wrapper for working with the Keychain in iOS, KFKeychain class is able to save, load and delete from iOS Keychain arbitrary objects, including, for example, NSString and NSDictionary.

Let's assume that we want to store user authorization token in iOS keychain. In this case code might look like that:

- (void)saveAuthToken:(NSString *)authToken {
    [KFKeychain saveObject:authToken forKey:kUserAuthTokenKey];
}

- (NSString *)authToken {
    return [KFKeychain loadObjectForKey:kUserAuthTokenKey];
}

- (void)removeAuthToken {
    [KFKeychain deleteObjectForKey:kUserAuthTokenKey];
}

For Swift version of this code please take a look at Keychain-iOS-Swift
