{
    UIImage *thumb=[_images objectAtIndex:i];
    UIButton *button=[UIButton buttonWithType:UIButtonTypeCustom];
    button.frame=CGRectMake(coloumn*100+24, row*80+30, 64, 64);
    [button setImage:thumb forState:UIControlStateNormal];
    [button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
    button.tag=i;
    [view addSubview:button];
    if (coloumn==2) {
        coloumn==0;
        row++;

This works very well but you would have to make a few adjustments to the code when you change the size. Copy and paste it in your Viewdidload; make sure you have a UIScrollview with IB already setup with a link name scrollView.

int row    = 0;
int colomn = 0;
int width  = 79;
int height = 79;
int offset = 1;
// int diff   = width * 0.5;
CGRect rect;

for (int i = 0; i < 45; i++) {

    if(i == 0){

        colomn = 0;

    }else{

        colomn += width + offset;

    };

    if(colomn >= ((int)scrollView.frame.size.width) - width){

        colomn = 0;
        row += height + offset;

    }

       rect =  CGRectMake(colomn, row, width, height);


    UIView *view = [[UIView alloc] initWithFrame:rect];
    [view setBackgroundColor:[UIColor redColor]];
    [scrollView addSubview:view];

}

[scrollView setContentSize:CGSizeMake(320, row+height)];

The problem with your code is here:

if (coloumn==2) {
    coloumn==0;   //-- ERROR!
    row++;

this should be:

    coloumn=0;   //-- correct!

using == instead of =

Use the three20 library

Edited:

Your code are excellent except on wrong statement :

coloumn==0;

that's the reason your colomn always point to the 2nd coloumn.

So change it to coloumn = 0;
