How to create Grid of Buttons on iphone.
10/10 matrix...
I found NSMatrix for MAC ... Not for iphone...
any alternative way to create grid of button on my view.
#Thanks in advance.

Answer 1

Manually?
int rows = 10;
int cols = 10;
float gridWidth = 320.0;
float gridHeight = 320.0;
float buttonWidth = 28.0;
float buttonHeight = 28.0;
float gapHorizontal = (gridWidth - (buttonWidth * rows)) / (rows + 1);
float gapVertical = (gridHeight - (buttonHeight * cols)) / (cols + 1);
float offsetX;
float offsetY;
int count = 0;
do {
offsetX = gapHorizontal + ((count % rows) * (buttonWidth + gapHorizontal));
offsetY = gapVertical + ((count / rows) * (buttonHeight + gapVertical));
UIView *aView = [[UIView alloc] initWithFrame:CGRectMake(offsetX, offsetY, buttonWidth, buttonHeight)];
aView.backgroundColor = [UIColor redColor];
[self.view addSubview:aView];
[aView release];
offsetX+= buttonWidth + gapHorizontal;
count++;
} while(count < rows * cols);

Also check out AQGridView. I guess it's pretty much what you are looking for. And more.

Answer 3

As I usually use this to make grid.. Only you have to just replace with your row and column
#define MatrixRow 3
#define MatrixColumn 3
#define GRID_WIDTH 300
#define GRID_HEIGHT 300
UIView *grid = [[UIView alloc] initWithFrame:CGRectMake(10, 50, GRID_WIDTH, GRID_HEIGHT)];
grid.backgroundColor = [UIColor brownColor];
for (int i = 0; i< (MatrixColumn*MatrixRow); i++) {
UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 40, 40)];
view.backgroundColor = [UIColor yellowColor];
CGFloat xOrigin = GRID_WIDTH/(MatrixColumn*2) + (GRID_WIDTH/MatrixColumn)*(i%MatrixColumn);
CGFloat yOrigin = GRID_HEIGHT/(MatrixRow*2) + (GRID_HEIGHT/MatrixRow) *(i/MatrixColumn);
NSLog(#" (\"%.2f\" , \"%.2f\")",xOrigin,yOrigin);
view.center = CGPointMake(xOrigin, yOrigin);
[grid addSubview:view];
}
[self.view addSubview:grid];
