我正在尝试根据用户的选择在另一个ViewController中更改UIIMageView。但我得到了恼人的错误！我错过了什么？
import UIKit
class StarbucksRefreshersBeverages：UIViewController，UITableViewDelegate {
@IBAction func doneButtonPressed(sender: AnyObject) {
self.dismissViewControllerAnimated(true, completion: nil)
}
var drink = "blah"
var refreshersDrinks = ["Cool Lime Starbucks Refreshers", "Valencia Orange Starbucks Refreshers", "Verry Berry Hibiscus Starbucks Refreshers"]
var refresherDrink = "blahblah"
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return refreshersDrinks.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "starbucksRefreshersPrototypeCell")
cell.textLabel?.text = refreshersDrinks[indexPath.row]
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
self.refresherDrink = refreshersDrinks[indexPath.row]
self.performSegueWithIdentifier("starbucksRefreshersToImageViewSegue", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
var detailViewController = segue.destinationViewController as RefreshersImageView
detailViewController.refresherDrink = self.refresherDrink
if self.refresherDrink == "Cool Lime Starbucks Refreshers" {
detailViewController.refreshersImageView.image! == UIImage( contentsOfFile: "coolLime.png")!
}
if self.refresherDrink == "Valencia Orange Starbucks Refreshers" {
detailViewController.refreshersImageView == UIImage(contentsOfFile: "valenciaOrange.png")
}
}
}
我已经看了对方的问题但却什么都不懂:(请帮助我。顺便说一下，我对编程很新，我只有15岁）所以请在评论中理解，请按照我的方式回答能够理解。 非常感谢并提前感谢
