TyphoonConfig factories shorthands

When moving some business logic from assembly to properties file, I face with problem when I want to specify application settings in properties file.

For example, I want to specify offline mode in properties file. Let's look at how this can be done.
I have next definitions:

- (id)webService;
- (id)afnetworkConnection;
- (id)offlineConnection;

webService definition requires afnetworkConnection/offlineConnection definition as dependency.

Then I have to create ConnectionFactory class:

@interface ConnectionFactory : NSObject
@property (nonatomic) BOOL offline;
@property (nonatomic, strong) MyAssembly *assembly;
- (id) newConnection;
@end

where

- (id)newConnection
{
    if (self.offline) {
        return [self.assembly offlineConnection];
    } else {
        return [self.assembly afnetworkConnection];
    }
}

then, create definitions:

- (id)connectionFactory
{
    return [TyphoonDefinition withClass:[ConnectionFactory class] configuration:^(TyphoonDefinition *definition) {
        [definition injectProperty:@selector(assembly) with:self];
        [definition injectProperty:@selector(offline) with:TyphoonConfig(@"webservice.offline")];
    }];
}

- (id)connection
{
    return [TyphoonDefinition withFactory:[self connectionFactory] selector:@selector(newConnection)];
}

and finally I can inject connection definition into webService definition.

Hope all was clear.

Now I want to introduce extension for TyphoonDefinition to simplify this case.
Instead of adding the 2 definitions and implementing the factory class just adding the one definition:

- (id)connection
{
    return [TyphoonDefinition withConfig:TyphoonConfig(@"webservice.offline") 
                                     yes:[self offlineConnection] 
                                      no:[self afnetworkConnection]];
}

where "webservice.offline" - bool value.

and another method for string value:

- (id)tokenStorage
{
    return [TyphoonDefinition withConfig:TyphoonConfig(@"webservice.tokenStorage") 
                                 mapping: @{ 
                                             @"keychain" : [self keychainStorage], 
                                             @"userDefaults" : [self userDefaultsStorage],
                                             @"database" : [self databaseStorage]
                                 }];
}

Where is the example in tests?

Check the AssemblyWithDefinitionConfiguration.m file

Looks good. Last task is to update the documentation. Will do this shortly.
