Getting images from url in Table View asynchronously


Tag : ios , By : Longchao Dong

will help you I would highly recommend using AFNetworking simply because it takes care of these kind of concerns.
At the very least, take a look at their UIImageView category as it allows you to do this:
UIImageView *imgView = //alloc, get it from a nib, whatever;
[imgView setImageWithURL:[NSURL URLWithString:@"StringPath"]];

loaded nib but the view outlet was not set while assigning a custom view for UITableView's header

I wish did fix the issue. I'm trying to make a custom view for UITableView header, but, unfortunately, I get an exception: , use this line of code
 {   
 ImageViewcontroller *imageView=[[ImagesViewController alloc]initwithnibname:@"ImageViewController" bundle:nil];       
 }

In iOS, is there a difference between adding a view as a subview versus assigning a view to the view property?

Does that help They are not identical but functionally they are similar. Here's a demonstration of the difference:
override func viewDidLoad() {
    super.viewDidLoad()

    self.view.backgroundColor = UIColor.blue
    let sceneView = UIView(frame: self.view.frame)
    sceneView.backgroundColor = UIColor.red
    self.view.addSubview(sceneView)
}
override func viewDidLoad() {
    super.viewDidLoad()

    self.view.backgroundColor = UIColor.blue
    let sceneView = UIView(frame: self.view.frame)
    sceneView.backgroundColor = UIColor.red
    self.view = sceneView
}
override func loadView() {
    let sceneView = UIView(frame: UIScreen.main.bounds)
    sceneView.backgroundColor = UIColor.red
    self.view = sceneView
}

NodeJS: Assigning to variable data retrieved asynchronously in Firebase


Tag : node.js , By : Caleb Ames

seems to work fine I'm developing a simple Firebase backend for a Dialogflow chatbot. The app interacts with a few databases and retrieves data from them. My code looked something like this: , As far as I can see you're looking to do:
function function_A(assistant) {
    let key_a = assistant.getArgument(KEY_A_NAME); 
    retrieve_from_database(database_a, key_a, PROPERTY_A_NAME).then(function(property) {
      if (property == null) {
        assistant.tell('Error Message');
      }
      else {
        <do something with property>
      }
    }
}

Risk of asynchronously assigning a JavaScript variable

I wish this help you JavaScript is always synchronous with itself. This is not true multi-threading, which JS does not support or use.
