Image 如何在解析中获取图像，单元格名称起作用，但图像不加载

我可以从parse加载图像，但它们有一个代码名，我想在单元格中显示图像，不要加载图像

//
import UIKit
import Parse
import Bolts

class LojasViewController: UIViewController, UITableViewDelegate {
    var ParseData = [PFObject]()
    var ParseImages = [PFFile]()

    @IBOutlet weak var saloesTableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // Retrieving Parse Information
        var query = PFQuery(className:"Saloes")
        query.orderByAscending("nome")
        query.findObjectsInBackgroundWithBlock {
            (objects: [AnyObject]?, error: NSError?) -> Void in

            if error == nil {
                // The find succeeded.
                println(objects!.count)

                // Do something with the found objects
                if let objects = objects as? [PFObject] {
                    self.ParseData = objects

                    println(self.ParseData.count)
                    self.saloesTableView.reloadData()
                    for object in objects {

                        println(object["nome"])
                        println(object["cidade"])
                        println(object["imagemCelula"])
                        println(object["endereco"])
                        println(object["GeoPonto"])
                        println(object["telefone"])
                        println(object["celular"])
                        println(object["texto"])

    override func prefersStatusBarHidden() -> Bool {
        return true
    }

    @IBAction func voltarButton(sender: AnyObject) {
        self.dismissViewControllerAnimated(true, completion: nil)

您可以使用FindObjectsInBackgroundithBlock获取解析对象。但是，一旦获得图像的解析对象，就需要通过调用getDataInBackgroundWithBlock下载实际文件

这是您的代码：

我更新了ParseImages，它现在是一个NSData数组

我实现了GetDataInBackgroundithBlock

我为imagemCelula分配了一个UIImage，该UIImage来自您从Parse检索到的图像

让我知道它是如何工作的

import UIKit
import Parse
import UIKit
import Parse
import Bolts

class LojasViewController: UIViewController, UITableViewDelegate {
var ParseData = [PFObject]()
var ParseImages: [NSData] = []

@IBOutlet weak var saloesTableView: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Retrieving Parse Information
    var query = PFQuery(className:"Saloes")
    query.orderByAscending("nome")
    query.findObjectsInBackgroundWithBlock {
        (objects: [AnyObject]?, error: NSError?) -> Void in

        if error == nil {
            // The find succeeded.
            println(objects!.count)

            // Do something with the found objects
            if let objects = objects as? [PFObject] {
                self.ParseData = objects

                println(self.ParseData.count)
                self.saloesTableView.reloadData()
                for object in objects {
                    object.getDataInBackgroundWithBlock({ (parseImageData, error) -> Void in
                if (error == nil) {
                    let thatImageData: NSData = parseImageData
                    ParseImages.append(thatImageData)

                        println(object["nome"])
                        println(object["cidade"])
                        println(object["imagemCelula"])
                        println(object["endereco"])
                        println(object["GeoPonto"])
                        println(object["telefone"])

谢谢昆汀，非常有用！现在我将修复object.getDataInBackgroundithBlock和伟大的KKKK
