我正在创建一个将数据从RecipiesViewController推送到TableViewController2的应用程序。 TableViewController2中的单元格使用TableViewCell2类。由于某些原因，单元格没有正确加载，而不是显示我输入的信息，它们只是显示空白。我一直试图找到错误一段时间，但由于一些奇怪的原因，我尝试的一切只是提出了同样的问题。这是我的TableViewController2类：
import UIKit
struct Recipe2 {
let name: String
let thumbnails: String
let description: String
}
class TableViewController2: UITableViewController {
var firstRecipe: Recipe?
var recipies2 = [Recipe2]()
let identifier: String = "Cell2"
var checked = [Bool]()
var toPass:String!
var lightPressed:String!
override func viewDidLoad()
{
super.viewDidLoad()
navigationItem.title = (firstRecipe?.name)! + " Instruments"
initializeTherecipies2()
// InstrumentTableCell.backgroundColor = UIColor.whiteColor()
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
return recipies2.count
}
func initializeTherecipies2()

这是我的TableViewCell2类：

self.thumbnailImage?.image = UIImage(named: recipie.thumbnails)
if nameLabel!.text == "Instrument"
{
backgroundColor = UIColor.orangeColor()
nameLabel?.textColor = UIColor.blackColor()
userInteractionEnabled = false
}
else if nameLabel!.text == "Optional addon"
{
backgroundColor = UIColor.cyanColor()
nameLabel?.textColor = UIColor.blackColor()
userInteractionEnabled = false
}
else
{
backgroundColor = UIColor.whiteColor()

}
}
}
