Adding Array of Buttons to Appropriate Table Rows

Vote count:

0

I am trying to populate a table with rows of buttons dynamically. When the table is launched, I pass it an array containing the correct buttons. The quantity of buttons, and thus rows, will vary. This works, until I need to create a new row (i.e. too many buttons to fit on the first row). Let's assume I limit it to 4 buttons per row. Then my buttons start on row 2, not row 1 like they should. They also get clipped on the right bounds.

Related code from numberOfRowsInSection

if ([[self fileTypeButtonsArray] count] % 4)
    return ([[self fileTypeButtonsArray] count] / 4) + 1;
else
     return [[self fileTypeButtonsArray] count] / 4;

Related code from cellForRowAtIndexPath:

for (int i = 0; i < [self.fileTypeButtonsArray count]; i++)
    {
         UIButton *currentButton = (UIButton *)[self.fileTypeButtonsArray objectAtIndex:i];
         [currentButton setTag:i];
         [currentButton setFrame:CGRectMake((kButtonPadding + (i * (kButtonWidth + kButtonPadding))), kButtonPadding, kButtonWidth, kButtonHeight)];
         [defaultCell.contentView addSubview:currentButton];
    }

Example Buttons exceeding 1 row - bad

Example Buttons fit on 1 row - good

I realize I'm just telling it to keep adding buttons to the right of each other. I'm stumped how I tell it which rows to put them in. Also stumped why they start in the second row (index 1), instead of top row (index 0). Thanks for any assistance.
