Making Network Request
var clientId = "Put your client id here"
var url = NSURL(string: "https://api.instagram.com/v1/media/popular?client_id=\(clientId)")!
var request = NSURLRequest(URL: url)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) { (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in
var responseDictionary = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as NSDictionary
self.photos = responseDictionary["data"] as NSArray
self.tableView.reloadData()
println("response: \(self.photos)")
}
Use setImageWithURL
Create the bridging file: create a new Objective-C file, name it anything, and when you save it, Xcode will prompt you generate a bridging file.
In an Objective-C bridging file:
#import <AFNetworking/UIImageView+AFNetworking.h>
In the swift view file, to set a imageView using URL:
setImageWithURL(NSURL(string: thumbnail))
Adding UIRefreshControl
//refreshControl is automatically defined in UITableViewController
override func viewDidLoad() {
super.viewDidLoad()
refreshControl = UIRefreshControl()
refreshControl.addTarget(self, action: "onRefresh", forControlEvents: UIControlEvents.ValueChanged)
scrollView.insertSubview(refreshControl, atIndex: 0)
}
//to stop refresh, call
self.refreshControl.endRefreshing()
