Я хочу загрузить изображения в метод connectionDidFinishLoading, и метод func connection (_connection: NSURLConnection, didReceive: Data) не вызывается
class ImageDownload: UIImageView,NSURLConnectionDelegate,NSURLConnectionDataDelegate
{
var imageSaved:UIImage!
var imageDownloaded:UIImage!
var connection2:NSURLConnection = NSURLConnection()
var data: NSMutableData = NSMutableData()
var urlstring:String = ""
var fileURL:URL!
let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true) as NSArray
var pathPlist:String!
func downloadImage()
{
let imgdownload :String = "http://image.tmdb.org/t/p/w500" + urlstring
// let urlnew: NSURL = NSURL(string: imgdownload)!
//print(urlnew,"url")
let url: NSURL = NSURL(string: imgdownload)!
let request1: NSMutableURLRequest = NSMutableURLRequest(url: url as URL)
// let request2: NSMutableURLRequest = NSMutableURLRequest(url: urlnew as URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 60.0)
connection2 = NSURLConnection(request: request1 as URLRequest, delegate: self, startImmediately: false)!
connection2.start()
}
func setURL(url:String) -> Void
{
print(url,"url")
urlstring = url
let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
fileURL = documentsDirectory.appendingPathComponent(url)
print(fileURL,"fileurl")
if FileManager.default.fileExists(atPath: fileURL.path)
{
let image = UIImage(contentsOfFile: fileURL.path)
print("file exists")
self.image = image
}

downloadImage()
