For data source I have use 5*5 dimensional array.

And also I am returning 5 for numberOfItems in

Answer 1

The MultipleLineLayout was originally written for infinite scrolling, so there was a problem with that implementation for your use. It should look like this,

-(NSArray*)layoutAttributesForElementsInRect:(CGRect)rect {

    NSMutableArray* attributes = [NSMutableArray array];
    for(NSInteger i=0 ; i < self.collectionView.numberOfSections; i++) {
        for (NSInteger j=0 ; j < [self.collectionView numberOfItemsInSection:i]; j++) {
            NSIndexPath* indexPath = [NSIndexPath indexPathForItem:j inSection:i];
            [attributes addObject:[self layoutAttributesForItemAtIndexPath:indexPath]];
        }
    }
    return attributes;
}
