Question

我有一个带有自定义单元格的TableView控制器，只要加载表格视图，我就想用新数据重新加载。

我遇到的问题是数据正在正确地重新加载但是细胞标签不是。

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


    jobSelect = Int(indexPath.row)



    var cell:  JobTableViewCell = tableView.dequeueReusableCellWithIdentifier("JobTableViewCell") as JobTableViewCell



    if indexPath.row % 2 == 0{cell.backgroundColor = UIColor.lightGrayColor()
    }
    else {cell.backgroundColor = UIColor.whiteColor()}


    var job = arrayOfJobs[indexPath.row]
    var totalHours = job.monHours + job.tueHours + job.wedHours + job.thuHours + job.friHours + job.satHours + job.sunHours

    cell.setCell(job.jobName, income: job.income, commute: job.commute, jobHours: totalHours)

    return cell
}

这是自定义单元格 -

import UIKit





class JobTableViewCell: UITableViewCell {

@IBOutlet var jobTitle: UILabel!

@IBOutlet var income: UILabel!
@IBOutlet var commute: UILabel!
@IBOutlet var jobHours: UILabel!



override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)
}

required init(coder aDecoder: NSCoder) {
    //fatalError("init(coder:) has not been implemented")
    super.init(coder: aDecoder)
}

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



    // Configure the view for the selected state
}

 func setCell(jobTitle: String, income: Int, commute: Int, jobHours: Int){





    self.jobTitle.text = String(arrayOfJobs[jobSelect
        ].jobName)
    self.income.text = String("Income: $\(arrayOfJobs[jobSelect].income) a month")
    self.commute.text = String("Commute: \(arrayOfJobs[jobSelect].commute) hours away from home")
    self.jobHours.text = String("Available hours:\(arrayOfJobs[jobSelect].monHours + arrayOfJobs[jobSelect].tueHours + arrayOfJobs[jobSelect].wedHours + arrayOfJobs[jobSelect].thuHours + arrayOfJobs[jobSelect].friHours + arrayOfJobs[jobSelect].satHours + arrayOfJobs[jobSelect].sunHours) hours a week")




 }
}

我还有一个第二个视图控制器设置，当选择一个单元格时出现 -

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



    jobSelect = Int(indexPath.row)


    var JobSelector:  jobSubView = storyboard?.instantiateViewControllerWithIdentifier("jobSubView") as jobSubView



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



    self.rowSelection = Int(indexPath.row)


}

这是子视图 -

import UIKit

class jobSubView: UIViewController {
@IBOutlet var jobTitle: UILabel!
@IBOutlet var income: UILabel!
@IBOutlet var commute: UILabel!
@IBOutlet var jobHours: UILabel!
@IBOutlet var qualifications: UILabel!
@IBOutlet var jobDescription: UITextView!

@IBOutlet var goBackButton: UIButton!
@IBOutlet var appluButton: UIButton!
@IBAction func applyButtonAction(sender: UIButton) {





override func viewDidLoad() {
    super.viewDidLoad()


    self.jobTitle.text = String(arrayOfJobs[jobSelect
        ].jobName)
    self.income.text = String("Income: $\(arrayOfJobs[jobSelect].income) a month")
    self.commute.text = String("Commute: \(arrayOfJobs[jobSelect].commute) hours away from home")
    self.jobHours.text = String("Available hours: \(arrayOfJobs[jobSelect].monHours + arrayOfJobs[jobSelect].tueHours + arrayOfJobs[jobSelect].wedHours + arrayOfJobs[jobSelect].thuHours + arrayOfJobs[jobSelect].friHours + arrayOfJobs[jobSelect].satHours + arrayOfJobs[jobSelect].sunHours) hours a week")


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

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

单元格和子视图上的标签来自相同的数据。第一次加载tableview时，单元格和子视图都会正确显示。

当选择单元格时，子视图会加载正确的数据，但是当我返回到tableview时，单元格标签应该更新，但它们不会更新。但子视图标签是。

有什么想法吗？

Answer 1

所以，我想出来了。您必须在viewWillAppear而不是viewDidLoad中执行self.tableView.reloadData（）。

TableViewCell没有更新
