If I compare Typhoon with one of the common IOC container spring in java i could not find two important freatures in the documentation.
How to annotate @autowired? How to annotate @Scope? Especially distinglish between SCOPE_SINGLETON and SCOPE_PROTOTYPE.
More about spring here: http://docs.spring.io/spring/docs/4.0.0.RELEASE/spring-framework-reference/html/beans.html#beans-standard-annotations
Typhoon supports the prototype and singleton scopes along with two other scopes designed specifically for mobile and desktop applications.
In a server-side application, the server may be supporting any of the application's use-cases at a given time. Therefore it makes sense for those components to have the singleton scope. In a mobile application, while there are background services its more common to service one use case at a time. And there are memory, CPU and batter constraints.
Therefore the default scope with Typhoon is TyphoonScopeObjectGraph, which means that references to other components while resolving eg a top-level controller will be shared. In this way an object graph can be loaded up and then disposed of when done.
There's also the following:
Auto-wiring macros vs native style assembly:
Unfortunately, Objective-C has only limited run-time support for "annotations" using macros. So the option was to use either a compile-time pre-processor, which has some drawbacks, or to work around the limitations and force it in using a quirky style. We decided that its best (for now) to use Macros only for simple convention-over-configuration cases.
For more control we strongly recommend using the native style of assembly. This allows the following:
To set the scope using the native style:
- (id)rootController
{
return [TyphoonDefinition withClass:[RootViewController class]
configuration:^(TyphoonDefinition* definition)
{
definition.scope = TyphoonScopeSingleton;
}];
}
