如何更改UITableView中项目的字体类型？我一直试图这样做，但我无法改变它。我是编程新手，所以请尽可能以最简单的方式解释。这是整个代码

**ViewController 1**
import UIKit
import Foundation

var items:[String] = []
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return items.count
}


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


    var cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "cell")
    cell.textLabel?.text = items[indexPath.row]
    return cell

}

override func viewWillAppear(animated: Bool) {
    if var storeditems: AnyObject? = NSUserDefaults.standardUserDefaults().objectForKey("items") {
        items = []
        for var i = 0; i<storeditems?.count; ++i {
            items.append(storeditems?[i] as NSString)
        }

        func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {

            if editingStyle == UITableViewCellEditingStyle.Delete {
                items.removeAtIndex(indexPath.row)
                NSUserDefaults.standardUserDefaults().setObject(items, forKey: "items")
                NSUserDefaults.standardUserDefaults().synchronize()

            }
        }
    }
}

}

**View Controller 2**

import UIKit

class ViewController2: UIViewController, UITextFieldDelegate {
@IBOutlet weak var textField: UITextField!

@IBAction func button(sender: AnyObject) {

    items.append(textField.text)

    NSUserDefaults.standardUserDefaults().setObject(items, forKey: "items")
    NSUserDefaults.standardUserDefaults().synchronize()

}


override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

/*
// MARK: - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    // Get the new view controller using segue.destinationViewController.
    // Pass the selected object to the new view controller.
}
*/

}

请使用以下代码设置tableview单元格字体以及背景颜色。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.selectionStyle = UITableViewCellSelectionStyleGray;
    }
    cell.textLabel.text = [yourAry objectAtIndex:(indexPath.row)];
    cell.textLabel.font = [UIFont fontWithName:@"Avenir Next" size:16]; // set font style
    cell.contentView.backgroundColor = [UIColor colorWithRed:239.0/255.0 green:239.0/255.0 blue:239.0/255.0 alpha:1.0]; // set tableview cell background color.
    return cell;
}

快速语言

func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
        var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell

        cell.textLabel.text = String(yourAry[indexPath.row] as NSString)
        cell.textLabel.font = UIFont (name: "Avenir Next", size: 16) // set font style

        return cell
