Set UIImageView image using a url

Question

Is it possible to read a url to an image and set a UIImageView to the image at this url?

Answer 1

For such a straightforward task I would highly recommend against integrating projects such as Three20, the library is a monster and not very straightforward to get up and running.

I would instead recommend this approach:

NSString *imageUrl = @"http://www.foo.com/myImage.jpg"; [NSURLConnection sendAsynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:imageUrl]] queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {     myImageView.image = [UIImage imageWithData:data]; }]; 

EDIT for Swift 3.0

let urlString = "http://www.foo.com/myImage.jpg" guard let url = URL(string: urlString) else { return } URLSession.shared.dataTask(with: url) { (data, response, error) in     if error != nil {         print("Failed fetching image:", error)         return     }      guard let response = response as? HTTPURLResponse, response.statusCode == 200 else {         print("Not a proper HTTPURLResponse or statusCode")         return     }      DispatchQueue.main.async {         self.myImageView.image = UIImage(data: data!)     } }.resume() 

*EDIT for Swift 2.0

let request = NSURLRequest(URL: NSURL(string: urlString)!)  NSURLSession.sharedSession().dataTaskWithRequest(request) { (data, response, error) -> Void in      if error != nil {         print("Failed to load image for url: \(urlString), error: \(error?.description)")         return     }      guard let httpResponse = response as? NSHTTPURLResponse else {         print("Not an NSHTTPURLResponse from loading url: \(urlString)")         return     }      if httpResponse.statusCode != 200 {         print("Bad response statusCode: \(httpResponse.statusCode) while loading url: \(urlString)")         return     }      dispatch_async(dispatch_get_main_queue(), { () -> Void in         self.myImageView.image = UIImage(data: data!)     })      }.resume()
