var restaurantIsVisited = [Bool](count: 21, repeatedValue: false)

var restaurantNames = ["Cafe Deadend", "Homei", "Teakha", "Cafe Loisl", "Petite Oyster", "For Kee Restaurant", "Po's Atelier", "Bourke Street Bakery", "Haigh's Chocolate", "Palomino Espresso", "Upstate", "Traif", "Graham Avenue Meats", "Waffle & Wolf", "Five Leaves", "Cafe Lore", "Confessional", "Barrafina", "Donostia", "Royal Oak", "Thai Cafe"]

    return self.restaurantNames.count
}

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

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

    // Configure the cell...
    cell.nameLabel.text = restaurantNames[indexPath.row]
    cell.thumbnailImageView.image = UIImage(named: restaurantImages[indexPath.row])
    cell.locationLabel.text = restaurantLocations[indexPath.row]
    cell.typeLabel.text = restaurantTypes[indexPath.row]

    // Circular image
    //   cell.thumbnailImageView.layer.cornerRadius = 10.0
    cell.thumbnailImageView.layer.cornerRadius =      cell.thumbnailImageView.frame.size.width / 2
    cell.thumbnailImageView.clipsToBounds = true

    if restaurantIsVisited[indexPath.row] {
        cell?.accessoryType = UITableViewCellAccessoryType.Checkmark
    } else {
        cell?.accessoryType = UITableViewCellAccessoryType.None
    }

    return cell
}

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    let optionMenu = UIAlertController(title: nil, message: "What do you want to do?", preferredStyle: .ActionSheet)

    let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
    optionMenu.addAction(cancelAction)

    self.presentViewController(optionMenu, animated: true, completion: nil)

    let callActionHandler = { (action: UIAlertAction!) -> Void in

        let alertMessage = UIAlertController(title: "Service Unavailable", message: "Sorry", preferredStyle: UIAlertControllerStyle.Alert)
        alertMessage.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
        self.presentViewController(alertMessage, animated: true, completion: nil)
    }

    let callAction = UIAlertAction(title: "Call" + "123-000-\(indexPath.row)", style: .Default, handler: nil)
    let isVisitedAction = UIAlertAction(title: "I've been here", style: UIAlertActionStyle.Default, handler: {
        (action:UIAlertAction!) -> Void in


        cell?.accessoryType = .Checkmark
        self.restaurantIsVisited[indexPath.row] = true
    })
    optionMenu.addAction(isVisitedAction)
}

Xcode表示它没有名为“accessoryType”的成员它还要求我删除问号。

以下是CustomTableViewCell的代码：

import UIKit

class CustomTableViewCell: UITableViewCell {
@IBOutlet weak var nameLabel: UILabel!
@IBOutlet weak var locationLabel: UILabel!
@IBOutlet weak var typeLabel: UILabel!
@IBOutlet weak var thumbnailImageView: UIImageView!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}

}

这没用，页面要求我添加更多细节，我不知道要添加什么，所以...... 更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多细节，更多详情，更多详情，更多详情，更多详情，更多详情，更多详情，更多详情，更多详情，更多详情，更多详情，更多详情，更多细节，更多详情，更多详情，更多详情，

Answer 1

您可以通过以下方式在swift中设置配件类型。

    cell.accessoryType = UITableViewCellAccessoryType.None
    cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator
    cell.accessoryType = UITableViewCellAccessoryType.DetailDisclosureButton

愿这对你有所帮助。

Answer 2

因为你的语法似乎正确

var cell = UITableViewCell(frame: CGRectMake(0, 0, 200, 200))

cell.accessoryType = UITableViewCellAccessoryType.Checkmark
cell.accessoryType = .Checkmark

两者似乎都在使用Swift 1.2的xCode Beta 6.3中工作

我只能认为您的单元格未正确初始化或未初始化为UITableViewCell

Swift中的另一种类型的单元格是UICollectionViewCell

var newCell = UICollectionViewCell(frame: CGRectMake(0, 0, 200, 200))

newCell.accessoryType = UICollectionViewCellAccessorryType.Checkmark

UICollectionViewCell 不有.accessoryType 因此，使用UIColectionViewCellAccessoryType 不是可能的尝试在.accessoryType访问UICollectionViewCell将导致错误’UICollectionViewCell’ does not have a member named ‘accessoryType’

如果您为细胞使用其他类型，请举例说明您的细胞类型确实有.accessoryType

尝试看看你是否按照你的意愿进行初始化

如何在Swift中使用accesoryType？
