ios - sendAsynchronousRequest 在 iOS 9 中被弃用，我该如何修复我的函数

Question

我的 UIImageView 上的一个扩展给我一个警告。我想要一个没有警告的项目，但我不确定如何正确解决这个问题。我收到的警告是这样的:

sendAsynchronousRequest was depricated in iOS 9.0: Use [NSURLSession dataTAskWithRequest....

引起警告的扩展是这样的:

extension UIImageView {
    public func imageFromUrl(urlString: String) {
        if let url = NSURL(string: urlString) {
            let request = NSURLRequest(URL: url)
            NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) {
                (response: NSURLResponse?, data: NSData?, error: NSError?) -> Void in
                if let imageData = data as NSData? {
                    self.image = UIImage(data: imageData)
                }
            }
        }
    }
}

试试这个

swift 3.0

URLSession.shared.dataTask(with: request) {data, response, error in
   if (error == nil) {
      //Do needful things // Your code . . . 
   } else {
      print("Error : \(error?.localizedDescription)");
   }
}.resume();
