Hook Class Static Function NSDocumentController : sharedDocumentController Failed!

[javaliker]

When I use Aspects Hook NSDocumentController : sharedDocumentController

[NSDocumentController aspect_hookSelector:@selector(sharedDocumentController) withOptions:AspectPositionBefore usingBlock:^(id<AspectInfo> info) {

    AspectInfo *appInfo = info;

    NSDocumentController *dvc = appInfo.instance;



} error:NULL];

Console log indicates NSMethodSignature doesn't match,But I think is OK,Can you give me some sugesstion ?

Aspects: Block signature <NSMethodSignature: 0x600000078600> doesn't match (null).
