How to create a grid of UIButtons with dynamic values in iOS?

Question

I am trying to create a grid of UIButtons . The row and column values are dynamic.I know how to create a grid .However making it using dynamic values is the problem.

 -(void)makeLayoutWithMinRow:(int)minRow maxRow:(int)maxRow minColumn:(int)minColumn maxColumn:(int)maxColumn {

    NSInteger intLeftMargin = 10; // horizontal offset from the edge of the screen
    NSInteger intTopMargin  = 10; // vertical offset from the edge of the screen
    NSInteger intYSpacing   = 30; // number of pixels between the button origins (vertically)
    NSInteger intXTile;
    NSInteger intYTile;

    NSInteger width;

    width = ((self.layoutView.frame.size.width-(maxColumn * 5))/maxColumn);
    for (int y = minRow; y < maxRow; y++)
    {
        for (int x = minColumn; x < maxColumn; x++)
        {
            intXTile = (x * width) + intLeftMargin;
            intYTile = (y * intYSpacing) + intTopMargin;
            UIButton *buttons[x][y] = [[UIButton alloc] initWithFrame:CGRectMake(intXTile, intYTile, width, 15)];
            //Here I get error : Variable-sized object may not be initialised.

            [self.layoutView addSubview:buttons[x][y]];
        }
    }
}

I did try the option as suggested by Cornelius below to store the button in array.

 sButton = [[UIButton alloc] initWithFrame:CGRectMake(intXTile, intYTile, width, 15)];
 [buttons addObject:sButton]; 

How to add these buttons to view in this case?

for (UIButton *obj in buttons) {
    [self.layoutView addSubview:obj];    //Doesn't work

}

Answer 1

Here is the one which replaces UICollectionView.I have tried PSTCollectionView and it gives you the expected results. Try this.

You can use PSTCollectionView.

Use UICollectionView to create such grid.

Here is a tutorial. For your case, it's UIButton instead of UIImageView in this tutorial.
