我想爲我的字典ex SE,CS,默認情況下不同的專業分配一個圖像,但每次運行該程序時,它崩潰在我身上。我正在使用一個tableview並有一個subtile風格。我應該先分配一些東西給專業嗎?這裏是我的tableviewcontroller指定圖像鍵值(斯威夫特)
import UIKit
class ClassRosterTableViewController: UITableViewController {
var studentsList = [Dictionary<String, String>]()
override func viewDidLoad() {
super.viewDidLoad()
let myStudentRoster = ClassRosterModel()
studentsList = myStudentRoster.studentsRoster
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("studentCell", forIndexPath: indexPath)
// Configure the cell...
cell.textLabel?.text = studentsList[indexPath.row]["name"]
cell.detailTextLabel?.text = studentsList[indexPath.row]["number"]
print("Student's name: \(studentsList[indexPath.row]["name"])")
print("Student's number: \(studentsList[indexPath.row]["number"])")
print("Student's email: \(studentsList[indexPath.row]["email"])")
if let major = studentsList[indexPath.row]["major"] {
switch (major) {
case "SE":
cell.imageView?.image = UIImage(named:"SE")!
case "CS":
cell.imageView?.image = UIImage(named:"CS")!
default:
cell.imageView?.image = UIImage(named:"default")!
}
}
return cell
}
//here is my separate class for the studentslist
import Foundation
class ClassRosterModel {
var studentsRoster = [Dictionary<String, String>]()
init() {
studentsRoster.append(["name": "Kaczynski, Alex", "major" : "SE", "email" : "s\(rand1)@monmouth.edu", "currentTerm" : "Spring", "numberOfCredits" : "\(rand2)" ])
studentsRoster.append(["name": "O'Rore, Ryan", "major" : "SE", "email" : "s\(rand1)@monmouth.edu", "currentTerm" : "Fall", "numberOfCredits" : "\(rand2)" ])
}
}
什麼行崩潰,什麼是故障控制檯消息?你的代碼中有很多驚歎號;其中每一個都意味着「請讓我崩潰」。你不會感到驚訝,如果它_does_崩潰;你自找的。 – matt
非常感謝,我不知道他們對代碼有這樣的影響,刪除它們,然後刪除中斷點就是實際存在的問題,並停止了我的代碼的工作。 –
