I have 4
and different data has to be fetched from api for every view controller.
The data has been fetched one by one but how to fetch data for all
at the same time.
As i know i can use
and delegate methods for once and i have to implement methods for 4 collection view in one but it app crashes giving error
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[HomeScreenViewController collectionView:cellForItemAtIndexPath:]: unrecognized selector sent to instance.
Can anyone tell me how to solve this problem??
