自定义单元格:

import UIKit

class RestaurantTableViewCell: UITableViewCell {

@IBOutlet var nameLabel: UILabel!
@IBOutlet var locationLabel: UILabel!
@IBOutlet var typeLabel: UILabel!
@IBOutlet 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
}

}
我的所有插座都连接到正确的标签/图像。我试着连接和断开它们,但没用

这是我的主要情节提要:


如果没有看到异常的开头,我的最佳猜测是您没有在情节提要中为单元格提供正确的
重用标识符,或者您没有将单元格设置为自定义类

此类不符合key locationLabel的键值编码


这意味着未设置
locationLabel
的插座。因此,您的代码正在崩溃,因为它试图访问一个为零的变量(在本例中是一个出口)。

您使用的是故事板吗?如果是这样,我们可以有一张图片吗?如果图片不在线,只在我的桌面上,我如何添加图片@CharlesTruluckYou可以在post编辑器中上传它。只需点击屏幕底部的
编辑
,然后选择
图片图标
。然后可以将其从桌面拖到浏览器窗口。(如果这是你的意思)点击链接查看我的Xcode屏幕@CharlesTruluckI,看看有更多的错误,如pbush25所说。向上滚动并将我们粘贴到错误报告的顶部。我在自己的代码中多次看到这一点:(很快就学会了找到这个!这很有帮助!谢谢@Swinny89谢谢@CharlesTruluckI不得不回到这个问题上来,因为在我测试它时,它实际上没有工作。我已经更新了我的代码,你可以在上面看到。@Swinny89实际上刚刚修复了它,谢谢你的帮助!@swiny89
