NitroKeychain is a thin, yet powerful, abstraction layer on top of iOS keychain that provides commonly needed features. NitroKeychain is also thread safe.

There are 3 operations: save, load and delete, as you can see below:

Saving

[TNTKeychain save: @"com.myapp.service.id" 
             data: @"my-ultra-secret-token"];

// Or, if you want to make this item available across apps, specify 
// an access group:
[TNTKeychain save: @"com.myapp.service.id" 
             data: @"my-ultra-secret-token"
      accessGroup: @"super-company"];

• All keychain items are stored using the kSecClassGenericPassword Keychain Item class.
• data can be any value compatible with NSKeyedArchiver/NSKeyedUnarchiver.
• If there is already some data associated with a keychain item ID, it will be updated.

Loading

NSString *token = [TNTKeychain load: @"com.myapp.service.id"];
NSLog( @"%@", token );

Deleting

[TNTKeychain delete: @"com.myapp.service.id"];

Simple as that

Requirements

iOS 6.0 or higher, ARC only
