Don't reuse cell in UITableView

问题

let cell = tableView.dequeueReusableCellWithIdentifier("cellReuseIdentifier", forIndexPath: indexPath) as! CustomTableViewCell

I don't want to reuse the cells once the cell is created, I want it to be available in memory.

It's your decision of course, but it's a very bad idea. Unless you have less than 10 cells in your tableView and you are 100% sure there will be no more cells. Otherwise the app will crash on memory pressure pretty fast.

Just don't dequeue cells. Create new each time:

let cell = UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: "CellReuseIdentifier")

Not recommended, but it's your decision after all.

回答2:

If you have limited number of cell then only you should use this method

On viewDidLoad() you can create NSArray of custom cell

 self.arrMainCell.addObject(your custom cell);

 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return self.arrMain.count
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell = self.arrMain.objectAtIndex(indexPath.row)

 }
