ios - Dynamically change cell spacing UICollectionView -


was having issues uicollectionview , spacing of cells. figured out how change spacing , works portrait view not landscape view. tried differentiate:

//set minimum spacing if(uideviceorientationislandscape([uidevice currentdevice].orientation)){      layout.minimumlinespacing = 100.0f; } else{      layout.minimumlinespacing = 40.0f; }

but unfortunately doesn't change when switch portrait landscape. can tell me how can achieve this?

try 

- (void)didrotatefrominterfaceorientation:(uiinterfaceorientation)frominterfaceorientation {     [yourcollectionview performbatchupdates:nil completion:nil]; }
