將圖像從tableView傳遞到Swift中的viewController

我在Assets文件夾中有圖像，並且Im試圖將數據從tableView傳遞到下一個viewController.I有兩個表格，我創建了UIImageView的出口。
ThirdView.swift包含結構
進口的UIKit將圖像從tableView傳遞到Swift中的viewController

struct ThirdView { 
var ThirdViewArray = [String]() 
var Pic = [String]() 
}

SecondTableViewController.swift包含

class SecondTableViewController: UITableViewController { 

var ExerciseListArray = [String]() 
var SecondAnswerArray = [String]() 



override func viewDidLoad() { 
    super.viewDidLoad() 
} 
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    return ExerciseListArray.count 
} 
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    var Cell = self.tableView.dequeueReusableCell(withIdentifier: "SecondCell", for: indexPath) as UITableViewCell 
    Cell.textLabel?.text = ExerciseListArray[indexPath.row] 

    return Cell 
} 

override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 
    var indexPath: NSIndexPath = self.tableView.indexPathForSelectedRow! as NSIndexPath 
    var DestViewController = segue.destination as! ExercisesViewController 
    DestViewController.FirstString = SecondAnswerArray[indexPath.row] 
    DestViewController.ExerciseImage = SecondAnswerArray[indexPath.row] 
} 


}

然而，SecondAnswerArray是String類型的，我得到一個錯誤：
「不能賦值類型爲UIImage的字符串「上線DestViewController.ExerciseImage = SecondAnswerArray [indexPath.row]
最後，FirstTableViewControl ler.swift：類FirstTableViewController：{的UITableViewController

var BodyPartsArray = [String]() 
var SecondArray = [SecondTable]() 
var ThirdArray = [ThirdView]() 

override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
    BodyPartsArray = ["Neck", "Shoulders", "Upper Arms", "Forearms", "Back", "Chest", "Waist", "Hips", "Thighs", "Calves"] 

    SecondArray = [ 
    SecondTable(SecondTitle: ["Neck1","Neck2","Neck3"]), 
    SecondTable(SecondTitle: ["Shoulders1","Shoulders2","Shoulders3"]), 
    SecondTable(SecondTitle: ["Upper Arms1","Upper Arms2","Upper Arms3"]), 
    SecondTable(SecondTitle: ["Forearms1","Forearms2","Forearms3"]), 
    SecondTable(SecondTitle: ["Back1","Back2","Back3"]), 
    SecondTable(SecondTitle: ["Chest1","Chest2","Chest3"]), 
    SecondTable(SecondTitle: ["Waist1","Waist2","Waist3"]), 
    SecondTable(SecondTitle: ["Hips1","Hips2","Hips3"]), 
    SecondTable(SecondTitle: ["Thighs1","Thighs2","Thighs3"]), 
    SecondTable(SecondTitle: ["Calves1","Calves2","Calves3"])] 

    ThirdArray = [ 
     ThirdView(ThirdViewArray: ["NeckText1","NeckText2","NeckText3"], Pic: []), 
     ThirdView(ThirdViewArray: ["ShouldersText1","ShouldersText2","ShouldersText3"], Pic: ["310","311","312"]), 
     ThirdView(ThirdViewArray: ["Upper ArmsText1","Upper ArmsText2","Upper ArmsText3"], Pic: ["313","314","315"]), 
     ThirdView(ThirdViewArray: ["ForearmsText1","ForearmsText2","ForearmsText3"], Pic: ["","",""]), 
     ThirdView(ThirdViewArray: ["BackText1","BackText2","BackText3"], Pic: ["","",""]), 
     ThirdView(ThirdViewArray: ["ChestText1","ChestText2","ChestText3"], Pic: ["","",""]), 
     ThirdView(ThirdViewArray: ["WaistText1","WaistText2","WaistText3"], Pic: ["","",""]), 
     ThirdView(ThirdViewArray: ["HipsText1","HipsText2","HipsText3"], Pic: ["","",""]), 
     ThirdView(ThirdViewArray: ["ThighsText1","ThighsText2","ThighsText3"], Pic: ["","",""]), 
     ThirdView(ThirdViewArray: ["CalvesText1","CalvesText2","CalvesText3"], Pic: ["","",""])] 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    return BodyPartsArray.count 
} 

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let Cell = self.tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as UITableViewCell 
    Cell.textLabel?.text = BodyPartsArray[indexPath.row] 

    return Cell 
} 

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

    let indexPath: NSIndexPath = self.tableView.indexPathForSelectedRow! as NSIndexPath 
    let DestViewController = segue.destination as! SecondTableViewController 
    var SecondTableArrayTwo: SecondTable 
    SecondTableArrayTwo = SecondArray[indexPath.row] 
    DestViewController.ExerciseListArray = SecondTableArrayTwo.SecondTitle 


    var ThirdAnswerArray: ThirdView 
    ThirdAnswerArray = ThirdArray[indexPath.row] 
    DestViewController.SecondAnswerArray = ThirdAnswerArray.ThirdViewArray 
    DestViewController.SecondAnswerArray = ThirdAnswerArray.Pic 
} 

}

再次，我上了線DestViewController.SecondAnswerArray = ThirdAnswerArray.Pic

ExercisesViewController了同樣的錯誤：
進口的UIKit

類ExercisesViewController：UIViewController {

@IBOutlet weak var TextView: UITextView! 
@IBOutlet weak var ImageView: UIImageView! 

var FirstString = String() 
var ExerciseImage = String() 

override func viewDidLoad() { 

    TextView.text = FirstString 
    ImageView.image = ExerciseImage 

} 
}

任何人都可以幫助我解決這個錯誤，也顯示我的資產加載圖片到FirstTableViewController.swift ThirdArray的我的UIImageView的正確方法？
謝謝

將是很好，如果你可以分享ExercisesViewController的代碼有更好的建議，但是這可能會幫助您：

首先，變量DestViewController.ExerciseImage in ExercisesViewController可能是類型UIImage，在您的陣列上SecondAnswerArray您包含Strin類型的對象G。如下聲明：

var SecondAnswerArray = [String]()

當您從SecondAnswerArray值分配給預期爲的UIImage一個對象，你會得到錯誤說

Cannot assign value of type String to type UIImage"

變化的類型ExercisesViewController.ExerciseImage是類型字符串這將解決您的第一個問題。

要從資源文件夾設置圖像您簡單指定一個圖像文件名到的UIImage，如：

let img = UIImage(named: "NAME_OF_YOUR_FILE_WITHOUT_EXTENSION")

那麼圖像設置爲的UIImageView

imageView.image = img

希望這有助於

感謝您的回覆，我已將ExercisesViewController添加到我的原始問題。我已經改變了ExerciseImage並且將Pic改成了String，並且錯誤消失了。但是，因爲ExerciseImage現在是String類型，而ImageView是UIImageView類型，所以現在我得到相同的錯誤。我應該將IBOutlet類型更改爲anyObject嗎？ – lukas28277

否的ImageView應保持一個UIImageView，但你應該用你的String對象發起一個UIImage，然後將其分配給您的圖像視圖像這樣： imageView.image =的UIImage（命名爲：ExerciseImage）這是假設你ExerciseImage是您嘗試加載的圖像文件的名稱。如果答案對您有幫助，請將其標記爲正確。 – Shachar

Cannot assign value of type String to type UIImage" on the line DestViewController.ExerciseImage = SecondAnswerArray[indexPath.row]

錯誤信息告訴你一切。 ExerciseImage是UIImage的類型，您正在爲其分配字符串。

首先創建UIImage對象比它分配給ExerciseImage

let image = UIImage(named: SecondAnswerArray[indexPath.row]) 
DestViewController.ExerciseImage = image
