how to aovoid situation in which gridView is covering my uilabel now:iphone

What I am having right now is ``` View : 1.UILabel : show a text 2.A GMGridView : show a grid of views ``` The codes are ``` - (void)viewDidLoad { [super viewDidLoad]; gridViewHolder.itemSpacing = SPACING; gridViewHolder.dataSource = self; gridViewHolder.actionDelegate = self; } #pragma mark - GMGridViewDataSource - (CGSize)GMGridView:(GMGridView *)gridView sizeForItemsInInterfaceOrientation:(UIInterfaceOrientation)orientation { return CGSizeMake(WIDTH, HEIGT); } - (NSInteger)numberOfItemsInGMGridView:(GMGridView *)gridView { return [needs count]; } - (GMGridViewCell *)GMGridView:(GMGridView *)gridView cellForItemAtIndex:(NSInteger)index { cell = [gridView dequeueReusableCell]; CGSize size = [self GMGridView:gridViewHolder sizeForItemsInInterfaceOrientation:UIInterfaceOrientationPortrait]; if (!cell) cell = [[GMGridViewCell alloc] init]; UIView *innerView = [[UIView alloc] initWithFrame:CGRectMake(COOR_X, COOR_Y, size.width, size.height)]; innerView.backgroundColor = [UIColor grayColor]; cell.contentView = innerView; return cell; } ``` So now I can successfully to display a bunch of views in gridview. However, the content of the grid view will cover the label when I am scrolling the grid view. Below is the picture so that you can see my situation now How can avoid this situation so that whenever I scroll up my gridview, its contents wont be overlapped with my uilabel
