if error != nil {
print("have an error")
return
}// end the if error
let string = String(data: data!, encoding: .utf8)
if let string = string {
if string.contains("cel_song") {
DispatchQueue.main.async { [weak self] in
// present main view for check only
let tabBarController = MainVC()
self?.present(tabBarController, animated: true, completion: nil)
}// end the dispatch

})// end the task
task.resume()
my question please it's possible to register to some website using url request with post 5 parameters in swift language?
I'm using swift 3. I want to add timeout to URLSession when doing download task. I did use configuration to change my setting, however, it doesn't work. The code didn't perform timeout... If the server didn't response quickly, it will fail.
Here is my code:
import Foundation
import UIKit
extension UIImageView {
func loadImage(url: URL) -> URLSessionDownloadTask {
let session: URLSession = {
let configuration = URLSessionConfiguration.default
configuration.timeoutIntervalForRequest = 70
configuration.timeoutIntervalForResource = 70
return URLSession(configuration: configuration, delegate: nil, delegateQueue: nil)
}()
let downloadTask = session.downloadTask(with: url, completionHandler: { [weak self] url, response, error in
if error == nil, let url = url, let data = try? Data(contentsOf: url), let image = UIImage(data: data) {
DispatchQueue.main.async {
if let strongSelf = self {
strongSelf.image = image
}
}
}
})
downloadTask.resume()
return downloadTask
}
}
Any comment is appreciated!!
I am trying to use youtube api in ios swift, and following this tutorial
http://www.appcoda.com/youtube-api-ios-tutorial/
HTTP Status Code = 403
Error while loading channel details: nil
I'm using swift 3
var urlString = "https://www.googleapis.com/youtube/v3/search?part=snippet&q=\(textField.text)&type=\(type)&key=\(apiKey)"
urlString = urlString.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)!
// Create a NSURL object based on the above string.
let targetURL = URL(string: urlString)
// Get the results.
performGetRequest(targetURL, completion: { (data, HTTPStatusCode, error) -> Void in
if HTTPStatusCode == 200 && error == nil {
// Convert the JSON data to a dictionary object.
do {
let resultsDict = try JSONSerialization.jsonObject(with: data!, options: []) as! Dictionary<String, AnyObject>
// Get all search result items ("items" array).
let items: Array<Dictionary<String, AnyObject>> = resultsDict["items"] as! Array<Dictionary<String, AnyObject>>
// Loop through all search results and keep just the necessary data.
for i in 0 ..< items.count {
let snippetDict = items[i]["snippet"] as! Dictionary<String, AnyObject>
// Gather the proper data depending on whether we're searching for channels or for videos.
if self.segDisplayedContent.selectedSegmentIndex == 0 {
// Keep the channel ID.
self.desiredChannelsArray.append(snippetDict["channelId"] as! String)
}
else {
// Create a new dictionary to store the video details.
var videoDetailsDict = Dictionary<String, AnyObject>()
videoDetailsDict["title"] = snippetDict["title"]
videoDetailsDict["thumbnail"] = ((snippetDict["thumbnails"] as! Dictionary<String, AnyObject>)["default"] as! Dictionary<String, AnyObject>)["url"]
videoDetailsDict["videoID"] = (items[i]["id"] as! Dictionary<String, AnyObject>)["videoId"]
// Append the desiredPlaylistItemDataDict dictionary to the videos array.
self.videosArray.append(videoDetailsDict)
// Reload the tableview.
self.tblVideos.reloadData()
}
}
} catch {
print(error)
}
// Call the getChannelDetails(…) function to fetch the channels.
if self.segDisplayedContent.selectedSegmentIndex == 0 {
self.getChannelDetails(true)
}
}
else {
print("HTTP Status Code = \(HTTPStatusCode)")
print("Error while loading channel videos: \(error)")
}
// Hide the activity indicator.
self.viewWait.isHidden = true
})
return true
}
// MARK: Custom method implementation
func performGetRequest(_ targetURL: URL!, completion: #escaping (_ data: Data?, _ HTTPStatusCode: Int, _ error: NSError?) -> Void) {

First of all the JSON dictionary representation in Swift 3 is [String:Any] (aka Dictionary<String,Any>)
Second of all in Swift 3 all parameter labels in closures have been removed
func performGetRequest(_ targetURL: URL, completion: #escaping (Data?, Int, NSError?) -> Void) {
Do not use implicit unwrapped optionals for method parameter types. Either use regular optional (?) or non-optional.
Error 403 means Forbidden Access. Make sure you have the correct apiKey from google/youtube developer.
I also used the appcoda youtube api tutorial (which is in Swift 2 I think) and this is a working version of mine for swift 3.
func getVideosForChannelAtIndex() {
let urlString = "https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId=\(playlistID)&maxResults=\(maxResults)&key=\(apiKey)"
// Create a NSURL object based on the above string.
let targetURL = URL(string: urlString)
// Fetch the playlist from Google.
performGetRequest(targetURL!) { (data, HTTPStatusCode, error) -> Void in
if HTTPStatusCode == 200 && error == nil {
do {
self.videos = []
// Convert the JSON data into a dictionary.
let resultsDict = try JSONSerialization.jsonObject(with: data!, options: []) as! Dictionary<AnyHashable, Any>
// Get all playlist items ("items" array).
let items:Array<Dictionary<AnyHashable, Any>> = resultsDict["items"] as! Array<Dictionary<AnyHashable, Any>>
// Use a loop to go through all video items.
// for var i=0; i<items.count; ++i
for i in 0 ..< items.count {
let playlistSnippetDict = (items[i] as Dictionary<AnyHashable, Any>)["snippet"] as! Dictionary<AnyHashable, Any>
let video = Video()
video.title = playlistSnippetDict["title"] as? String
// video.thumbnail =
video.videoId = (playlistSnippetDict["resourceId"] as? Dictionary<AnyHashable, Any>)?["videoId"] as? String
guard let thumbnail = ((playlistSnippetDict["thumbnails"] as? Dictionary<AnyHashable, Any>)?["high"] as? Dictionary<AnyHashable, Any>)?["url"] as? String else {
video.thumbnail = UIImage(named: "Icon1024x1024")
return
}
guard let url:URL? = URL(string: thumbnail), let data:Data? = try? Data(contentsOf: url!) else {
video.thumbnail = UIImage(named: "Icon1024x1024")
return
}
if let dataImage = data {
video.thumbnail = UIImage(data: dataImage)
} else {
video.thumbnail = UIImage(named: "Icon1024x1024")
}
self.videos.append(video)
// Reload the tableview.
self.tblVideos.reloadData()
}
} catch {
print("json error: \(error)")
}
} else {
print("")
print("HTTP Status Code = \(HTTPStatusCode)")
print("")
//Show alertDialog here with Error
print("Error while loading videos: \(error?.localizedDescription)")
let alert = UIAlertView(title: "Oops!", message: error?.localizedDescription, delegate: self, cancelButtonTitle: "OK")
alert.show()
}
// Hide the activity indicator.
self.viewWait.isHidden = true
}
}
This is for the performGetRequest
func performGetRequest(_ targetURL: URL, completion: #escaping (_ data: Data?, _ HTTPStatusCode: Int?, _ error: Error?) -> Void) {
var request = URLRequest(url: targetURL)
request.httpMethod = "GET"
let sessionConfiguration = URLSessionConfiguration.default
let session = URLSession(configuration: sessionConfiguration)
let task = session.dataTask(with: request) { data, response, error in
DispatchQueue.main.async(execute: {
completion(data, (response as? HTTPURLResponse)?.statusCode, error)
})
}
task.resume()
}
