Ios9uicollectionview custom layout Modifying attributes returned by Uicollectionviewflowlayout without copying them

Uicollectionviewflowlayout has cached frame mismatch

This is likely occurring because the flow layout subclass Mylinelayout are modifying attributes returned by Uicollectionvie Wflowlayout without copying them

-(Nsarray *) Layoutattributesforelementsinrect: (cgrect) rect

Nsarray *original = [Super Layoutattributesforelementsinrect:rect];

Nsarray *array = [[Nsarray alloc] initwitharray:original Copyitems:yes];

Modify the array so that you do not modify the original

So you don't get this warning.
