iOS Obj C Typhoon Auto Inject in a View

Question

I have an iOS App with DI (Typhoon). In the Assembly I wrote this:

- (AvPlayerManager *)playerManager {
return [TyphoonDefinition withClass:[AvPlayerManager class]
                      configuration:^(TyphoonDefinition *definition)
        {
            definition.scope = TyphoonScopeSingleton;
        }]; }

I can use this AvPlayerManager class in a ViewControllerA.h with auto injection:@property (nonatomic, weak) InjectedClass(AvPlayerManager) playerManager; I have a collectionView and I want to use the playerManager in the cells. But If I try with the injectedClass macro the property will be nil.

My UI:

viewControllerA -> collectionView -> collectionViewCell

How can I use this singleton instance in the collectionViewCell.m?

If I understand your question correctly, you would like to declare you injected dependencies privately in the implementation (.m) rather than in the header?

The way to do this is to use a class extension inside the implementation file, for example:

MyFile.m

@interface AudioManager() // or whatever your class is called in .h

@property (nonatomic, weak) InjectedClass(AvPlayerManager) playerManager; 

@end

//rest of .m implementation follows. 

By the way, if you're using Swift in the future you might like to check out Typhoon's Swift successor, which is called pilgrim.ph.

If I understood your question correctly great, otherwise could you please clarify.
