load image from url in tableview cell from alamofire swift

Question

I am trying to load image from json using Alomofire and swiftyJSON. Json is dictionary:

{"name": {"image": "https://...",}}

Alamorefire and SwiftyJSON

var imageLoad: String!

Alamofire.request(.GET, url).responseJSON { (response) -> Void in
    if let value = response.result.value {
    let json = JSON(value)

    if let jsonDict = json.dictionary {

        let image = jsonDict["name"]!["image"].stringValue
        print(image) // https://....
        self.imageLoad = image        
    }
    self.tableView.reloadData()
    }
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! TVCell

// Configure the cell...

cell.imageTableView.image = UIImage(named: imageLoad) // not working "fatal error: unexpectedly found nil while unwrapping an Optional value"

If anyone can help? If there is another way feel free to write.

Answer 1

I share a code implemented using Swift 3 and AlamofireImage:

import UIKit
import AlamofireImage

class MovieViewCell: UICollectionViewCell {

@IBOutlet weak var titleLabel: UILabel!
@IBOutlet weak var overviewLabel: UILabel!
@IBOutlet weak var posterView: UIImageView!

 func configure(for movie: Movie) {
    titleLabel.text = movie.title
    overviewLabel.text = movie.overview

    let url = URL(string: movie.poster_path!)!
    posterView.af_setImage(withURL: url)
 }

 override func prepareForReuse() {
    super.prepareForReuse()

    posterView.af_cancelImageRequest()
    posterView.image = nil
 }
}

Also, you will need Cocoapods:

platform :ios, '10.0'

inhibit_all_warnings!
use_frameworks!

target 'MovieApp' do
  pod 'Alamofire', '~> 4.5'
  pod 'AlamofireImage', '~> 3.3'
end
