XCODE AppDelegate:self? Framework to Framework Communication for NSURLSession

please help!

goal: create cocoa touch framework syncing framework different cloud api storage services (azure, aws, filemaker api*)



currently, use filemaker pro filemaker go ios app sdk most. filemaker inc. has created cocoa touch framework bundle entire application within it, assume appdelegate , viewcontroller classes within it, can't tell because compiled.



create second framework coca touch can run background tasks / downloads triggered custom framework.

have been sucessfull @ embedding framework along side filemaker go's ios app sdk , running commands, can push json, json, , download files in main thread, once app goes sleep download triggered framework stops. using nsurlsession of this. try attach nsurlsession background config stops working , fails.



not have direct access app's appdelegate or viewcontroller classes. cannot modify them direclty.



nsurlsessionconfiguration *backgroundconfiguration = [nsurlsessionconfiguration backgroundsessionconfiguration"com.captech.nsurlsample.backgroundsession"]; nsurlsession *backgroundsession = [nsurlsession sessionwithconfiguration:backgroundconfiguration delegate:self delegatequeue:nil];



- (void)urlsessionnsurlsession *)session downloadtasknsurlsessiondownloadtask *)downloadtask didwritedataint64_t)byteswritten totalbyteswrittenint64_t)totalbyteswritten totalbytesexpectedtowriteint64_t)totalbytesexpectedtowrite { if (downloadtask == self.downloadtask && self.progressaction){ self.progressaction((double)totalbyteswritten, (double)totalbytesexpectedtowrite); } }


problem lies think in delegate:self identifier. never resolves. have tried removing nothing downloads. have tried pch prefix header identiy appdelegate not luck. trid (myappdd *) uiapp sharedapp delegate try reference since framework i'm building isnt embeded in app yet don't think can resolve.

if can figure out how reference appdelegate or around attaching new tasks can run background downloads cocoa touch framework awesome.

resources on nsurlsession usage tried, not luck delegate:self on background stuff. if don't need background execution works fine becuase don't have define delegate:self ever.

thoughts or suggestions on framework framework communication appdelegate self , viewcontroller awesome.

please remember coca touch framework building must able compile before being added filemaker skd ios app project.



thanks,

a few random comments:

background downloads complicated. if build separate app , background downloads working there before attempting integrate app you're building.

objective-c classdump tool. find names of classes in sdk. also, man nm.

can access app delegate directly uiapplication. can set own app delegate though sdk sets own. if did call through sdk app delegate delegate methods , should still work. there might other trickery add own callbacks background downloads.
