所以我正在设置一个UITableViewController来从Parse中检索图像文件，但是我遇到了一些问题。我相信它与dataDelegate或dataSource有关，但不确定......非常感谢帮助！
import UIKit
import Parse
class HomeTableViewController: UITableViewController {
var albumImageFiles = [PFFile]()
var imageText = [String]()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let query = PFQuery(className: "Posts")
query.orderByDescending("createdAt")
query.findObjectsInBackgroundWithBlock { (posts:[AnyObject]?, error: NSError?) -> Void in
if error == nil {
//success fetching objects
for post in posts! {
self.albumImageFiles.append(post["imageFile"] as! PFFile)
self.imageText.append(post["albumText"] as! String)
}
/*reload the table*/
//self.reloadData()
} else {
print(error)
}
}
//table view cell amounts
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return albumImageFiles.count
}
//
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let homeCell: HomeTableViewCell = tableView.dequeueReusableCellWithIdentifier("HomeCell") as! HomeTableViewCell
//text
homeCell.imageLabel.text = imageText[indexPath.row]
//images
albumImageFiles[indexPath.row].getDataInBackgroundWithBlock { (imageData: NSData?, error: NSError?) -> Void in
if imageData != nil {
let image = UIImage(data: imageData!)
homeCell.albumImage.image = image
} else {
print(error)
}
}
return homeCell
}
