Question

我有一个需要根据被点击的单元格调用的图像数组。例如，假设您有五个单元格，每个单元格都有自己的特定单元格信息。当您点击第一个单元格时，它会打开一个新页面，图像会显示该数组中的单元格以及随附的信息。现在，当您点击单元格2时，图像将填充以及专门用于单元格2的信息。如何从与被轻敲的单元格相关的数组中调用图像？我知道如何使用字符串，但我似乎无法弄清楚如何使用图像。当我尝试按照与字符串相同的方式进行操作时，我得到的只是错误。

这是代码的一部分：

import UIKit

class FacultyViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

@IBOutlet weak var table: UITableView!

var facultyMemeber: [String] = ["Ron Cervantes", "Darice Corey-Gilbert", "Devan Shepard", "Tom Sinclair"]

var image: UIImage  = [#imageLiteral(resourceName: "rcervantas"), #imageLiteral(resourceName: "dcorey"), #imageLiteral(resourceName: "dshepherd"), #imageLiteral(resourceName: "tsinclair")]

var bio: [String] = ["Ron is a tech billionaire who finds fulfillment in teaching!", "Darice oversees all aspects of Web design and development for Yale College.

var education: [String] = ["MS Management Information Systems | Keller Graduate School of Management 2007 \nBA Business w/concentration in MIS | University of Wisconsin-Parkside 1999", "MBA Information Technology and E-Business | Fairfield University 2002 \nBS Information Systems | Fairfield University 1998", "MS Information Technology | Capella University \nBA Psychology | Wilfrid Laurier University", "MS Computer Science | Loyola University, Chicago, Illinois \nBS Computer Science | Loyola University, Chicago, Illinois"]

var selectedRow: Int = -1

override func viewDidLoad() {
    super.viewDidLoad()

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

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    return facultyMemeber.count
}


 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let faculty:UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "faculty")!

    faculty.textLabel?.text = facultyMemeber[indexPath.row]

    return faculty
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    self.performSegue(withIdentifier: "Faculty", sender: nil)
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

    let detailView: DetailFacultyViewController = segue.destination as! DetailFacultyViewController

    selectedRow = (table.indexPathForSelectedRow?.row)!

    detailView.facultyNameString = facultyMemeber[selectedRow]
    detailView.bioString = bio[selectedRow]
    detailView.detailImage = image[selectedRow]
    detailView.educationString = education[selectedRow]


}
/*
// MARK: - Navigation

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

}

它的另一部分是：导入UIKit

class DetailFacultyViewController: UIViewController {

@IBOutlet weak var facultyName: UILabel!
@IBOutlet weak var image: UIImageView!
@IBOutlet weak var bio: UILabel!
@IBOutlet weak var education: UILabel!

var facultyNameString: String!
var detailImage: String!
var bioString: String!
var educationString: String!

override func viewWillAppear(_ animated: Bool) {
    super.viewDidLoad()

    setFacultyName()
    setBio()
    setEducation()

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

func setFacultyName () {
    facultyName.text = facultyNameString    }

func setBio() {
    bio.text = bioString
}

func setEducation() {
    education.text = educationString
}

func setImage() {
    image.image = detailImage
}
}

Answer 1

#imageLiteral(resourceName:)给了我们一个UIImage所以在你的情况下： - detailImage也应该是UIImage而不是String

变化：

var detailImage: String!

到

var detailImage: UIImage!

继续你正在做的事情：

image.image = detailImage

编辑：

同样改变：

var image: UIImage  = [#imageLiteral(resourceName: "rcervantas"),...]

到

//should be an array of images as per your design
var image: [UIImage]  = [#imageLiteral(resourceName: "rcervantas"),...]

最后致电setImage()

override func viewWillAppear(_ animated: Bool) {
    //...
    setImage()
}

试图调用图像数组
