SWIFT - UIimagepicker將圖像分配到數組

Question

基本上我希望我的ImagePicker能夠在每次用戶輸入名稱併爲此名稱選擇圖像時將捕獲的圖像分配給tableview中的新行。我遇到至少2種類型的錯誤代碼如下：

1）'UIImageView'不是'cell.itemImage.image = UIImage（named：selectedImageArray [indexPath.row] ）」

2）如何訪問例如一個問題‘.contentMode’和」 .clipsToBounds'所分配的圖像（即每個陣列中被分配到的tableview）

的性質欣賞任何人的幫助對這些~~

Tableview Controller：

import UIKit 

class AddPostItemTableViewController: UITableViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UITableViewDelegate { 

@IBOutlet var titleName: UILabel! 
@IBOutlet var tapCamera: UIImageView! 
@IBOutlet var tapLibrary: UIImageView! 
@IBOutlet weak var itemNameField:UITextField! 

@IBOutlet weak var AddPostTableView:UITableView! 

var selectedImageArray:[UIImageView!] = [] 
var selectedItemNameArray:[String!] = [] 

let tapCameraRec = UITapGestureRecognizer() 
let tapLibraryRec = UITapGestureRecognizer() 

override func viewDidLoad() { 
    super.viewDidLoad() 
    tapCameraRec.addTarget(self, action: "tappedCamera") 
    tapLibraryRec.addTarget(self, action: "tappedLibrary") 
    tapCamera.addGestureRecognizer(tapCameraRec) 
    tapLibrary.addGestureRecognizer(tapLibraryRec) 
    tapLibrary.userInteractionEnabled = true 
    tapCamera.userInteractionEnabled = true 

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


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

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) { 
    self.view.endEditing(true) 
    // Dismiss keyboard on touch 
} 

func tappedLibrary(){ 

    if itemNameField.text == "" { 
     let alertController = UIAlertController(title: "Oops", message: "Please key in the name of item first", preferredStyle: .Alert) 
     let doneAction = UIAlertAction(title: "OK", style: .Default, handler: nil) 
     alertController.addAction(doneAction) 

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

     return 
    } 

    else if UIImagePickerController.isSourceTypeAvailable(.PhotoLibrary) { 
     let imagePicker = UIImagePickerController() 
     imagePicker.allowsEditing = true 
     imagePicker.delegate = self 
     imagePicker.sourceType = .PhotoLibrary 

     self.presentViewController(imagePicker, animated: true, completion: nil) 
    } 
} 

func tappedCamera(){ 

    if itemNameField.text == "" { 
     let alertController = UIAlertController(title: "Oops", message: "Please key in the name of item first", preferredStyle: .Alert) 
     let doneAction = UIAlertAction(title: "OK", style: .Default, handler: nil) 
     alertController.addAction(doneAction) 

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

     return 
    } 

    else if UIImagePickerController.isSourceTypeAvailable(.PhotoLibrary) { 
     let imagePicker = UIImagePickerController() 
     imagePicker.allowsEditing = true 
     imagePicker.delegate = self 
     imagePicker.sourceType = .Camera 

     self.presentViewController(imagePicker, animated: true, completion: nil) 
    } 
} 

func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image:UIImageView!, editingInfo: [NSObject : AnyObject]!) { 
    selectedImageArray.append(image) 
    selectedImageArray.contentMode = UIViewContentMode.ScaleAspectFill 
    selectedImageArray.clipsToBounds = true 

    selectedItemNameArray.append(itemNameField!.text) 

    dismissViewControllerAnimated(true, completion: nil) 
} 

// MARK: - Table view data source 

override func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    // #warning Potentially incomplete method implementation. 
    // Return the number of sections. 
    return 1 
} 

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int 
{ 
    // Return the number of rows in the section. 
     return self.selectedItemNameArray.count 
} 

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

     let cellIdentifier = "ItemCell" 
     let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: 
      indexPath) as AddPostTableViewCell 

     // Configure the cell... 
     cell.itemName.text = selectedItemNameArray[indexPath.row] 
     cell.itemImage.image = UIImage(named: selectedImageArray[indexPath.row]) 

     return cell 
}

import UIKit 

class AddPostTableViewCell: UITableViewCell { 

@IBOutlet weak var itemName:UILabel! 
@IBOutlet weak var itemImage:UIImageView! 

override func awakeFromNib() { 
    super.awakeFromNib() 
    // Initialization code 
} 

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

    // Configure the view for the selected state 
} 

}

第一個錯誤表明您數組包含的UIImageViews，而不是圖像的名字。 UIImage（imageNamed：）接受圖像的名稱作爲字符串。您可能需要類似

cell.itemImage.image = selectedImageArray[indexPath.row].image 

或者如果您要使用UIImage（imageNamed :)，請改爲使用您的名稱數組。

關於第二個問題，你可以在[indexPath.row]之後加一個點來訪問存儲對象在給定索引處的屬性，就像我上面做的那樣。或者你可以用更可讀的方式做到這一點：

var myImage = selectedImageArray[indexPath.row] 
myImage.someProperty
