如何根据设备动态计算UITableViewCell的高度

Question

I have a UITableViewController now, and I have x cells for UITableView , which is the same height with screen. I don't want to scroll the UITableView , and I want to divide whole screen into x parts with the same height.

Do I have to check device type first, then calculate height of every cell? Then there are lots of if or switch statement. What the best way to achieve this?

Thanks.

Answer 1

Assume you have a Navigation Bar, try this:

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    let screenHeight = UIScreen.mainScreen().bounds.height
    return (screenHeight - 64) / <number of cells>
}

If you don't have Nagivation Bar, just replace

return (screenHeight - 64) / <number of cells>

with

return screenHeight / <number of cells>
