        UICollectionView *  collectionView = [[UICollectionView alloc]initWithFrame:self.view.bounds collectionViewLayout:self.hkLayout];
        collectionView.backgroundColor = [UIColor whiteColor];
        collectionView.delegate=self;
        collectionView.dataSource =self;
        [self.view addSubview:collectionView];
        [collectionView registerClass:[ZZCollectionViewCell class] forCellWithReuseIdentifier:kCellID];
        _hotKeyCollectView = collectionView;
    }
    return _hotKeyCollectView;
}

- (ZZHotKeysLayout *)hkLayout{
    if (_hkLayout == nil) {
        _hkLayout = [[ZZHotKeysLayout alloc]init];
        _hkLayout.flowEdgeInset = UIEdgeInsetsMake(20, 10, 15, 40);
        _hkLayout.rowSpace = 30;
        _hkLayout.columSpace = 15;
        _hkLayout.delegate = self;
    }
    return _hkLayout;
}

1. 实现相应代理方法

- (CGSize)hotKeysLayout:(ZZHotKeysLayout *)layout indexPath:(NSIndexPath*)indexPath;
