Getting Twitter Profile Image with Parse in Swift

Getting Twitter profile image with Parse in Swift

AHere is the Swift version. I had to change the username from Parse to screenName from PFTwitter, and added a line to get the highest resolution version of the picture. Note that as I'm using this to populate a sign up screen after logging in, this will test for the app account being connected to a Twitter account. Most probably this would work even if the link has been added after account creation, too.

    if PFTwitterUtils.isLinkedWithUser(PFUser.currentUser()!) {

let screenName = PFTwitterUtils.twitter()?.screenName!

let requestString = ("https://api.twitter.com/1.1/users/show.json?screen_name=" + screenName!)

let verify: NSURL = NSURL(string: requestString)!

let request: NSMutableURLRequest = NSMutableURLRequest(URL: verify)

PFTwitterUtils.twitter()?.signRequest(request)

var response: NSURLResponse?
var error: NSError?

let data: NSData = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)!

if error == nil {

let result = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments, error: &error)

let names: String! = result?.objectForKey("name") as! String

let separatedNames: [String] = names.componentsSeparatedByString(" ")

self.firstName = separatedNames.first!
self.lastName = separatedNames.last!

let urlString = result?.objectForKey("profile_image_url_https") as! String

let hiResUrlString = urlString.stringByReplacingOccurrencesOfString("_normal", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)

let twitterPhotoUrl = NSURL(string: hiResUrlString)
let imageData = NSData(contentsOfURL: twitterPhotoUrl!)
let twitterImage: UIImage! = UIImage(data:imageData!)
}

You probably want to add something like this to prepare a PFFile to save to your new user, too!

            let cgImage = twitterImage.CGImage

let bitsPerComponent = CGImageGetBitsPerComponent(cgImage)
let bytesPerRow = CGImageGetBytesPerRow(cgImage)
let colorSpace = CGImageGetColorSpace(cgImage)
let bitmapInfo = CGImageGetBitmapInfo(cgImage)

let context = CGBitmapContextCreate(nil, 300, 300, bitsPerComponent, bytesPerRow, colorSpace, bitmapInfo)

CGContextSetInterpolationQuality(context, kCGInterpolationHigh)

CGContextDrawImage(context, CGRect(origin: CGPointZero, size: CGSize(width: CGFloat(300), height: CGFloat(300))), cgImage)

let scaledImage = UIImage(CGImage: CGBitmapContextCreateImage(context))

let imageUIImage = UIImageJPEGRepresentation(scaledImage, 0.6)
let imageFile: PFFile = PFFile(name: (PFUser.currentUser().objectId! + "profileImage.jpg"), data:imageUIImage)

Getting Twitter profile image with Parse in Swift 2

Based on your code, I was able to get the Twitter image to be retrieved using:

if PFTwitterUtils.isLinkedWithUser(PFUser.currentUser()!) {

let screenName = PFTwitterUtils.twitter()?.screenName!
let requestString = NSURL(string: "https://api.twitter.com/1.1/users/show.json?screen_name=" + screenName!)
let request = NSMutableURLRequest(URL: requestString!, cachePolicy: .ReloadIgnoringLocalAndRemoteCacheData, timeoutInterval: 5.0)
PFTwitterUtils.twitter()?.signRequest(request)
let session = NSURLSession.sharedSession()

session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
print(data)
print(response)
print(error)

if error == nil {
var result: AnyObject?
do {
result = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.AllowFragments)
} catch let error2 as NSError? {
print("error 2 \(error2)")
}

let names: String! = result?.objectForKey("name") as! String
let separatedNames: [String] = names.componentsSeparatedByString(" ")

//self.firstName = separatedNames.first!
//self.lastName = separatedNames.last!

let urlString = result?.objectForKey("profile_image_url_https") as! String
let hiResUrlString = urlString.stringByReplacingOccurrencesOfString("_normal", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
let twitterPhotoUrl = NSURL(string: hiResUrlString)
let imageData = NSData(contentsOfURL: twitterPhotoUrl!)
let twitterImage: UIImage! = UIImage(data:imageData!)
}
}).resume()
}

I rolled the result handling into the data task and fixed the JSONObjectWithData:options: call for Swift 2.

Twitter user image Parse - Swift

Try with below code,

if let imageData = NSData(contentsOfURL: twitterPhotoUrl!)
{
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.userImg.image = UIImage(image: imageData!)
})
}

Hope this will work

Getting Twitter user details using swift

You can access the username and userID of the logged-in user pretty easily. Inside most Twitter login methods you'll see something like this:

@IBAction func loginTwitter(sender: UIBarButtonItem) {
Twitter.sharedInstance().logInWithCompletion {
(session, error) -> Void in
if (session != nil) {

print(session?.userName)
print(session?.userID)
} else {
print("error")

}
}
}

Twitter does not expose the email address of users as far as I'm aware.

For the profile image you'll need to send a GET request. Here is some code that may not be up to date with the latest TwitterKit version but should at least give you a sense of how the request should be formatted.

func getUserInfo(screenName : String){
if let userID = Twitter.sharedInstance().sessionStore.session()!.userID {
let client = TWTRAPIClient(userID: userID)
let url = "https://api.twitter.com/1.1/users/show.json"
let params = ["screen_name": screenName]
var clientError : NSError?
let request = Twitter.sharedInstance().APIClient.URLRequestWithMethod("GET", URL: url, parameters: params, error: &clientError)

client.sendTwitterRequest(request) { (response, data, connectionError) -> Void in
if let someData = data {
do {
let results = try NSJSONSerialization.JSONObjectWithData(someData, options: .AllowFragments) as! NSDictionary
print(results)

} catch {
}
}
}
}
}

You'll need to go through the JSON that gets returned and find "profile_image_url_https" a couple levels down.

Good Luck!

After convert my code to swift 3 Twitter not get the users profile image

This error occurs when the user name is incorrect. This should work.

let profilepic = FHSTwitterEngine.shared().getProfileImageURLString(forUsername: FHSTwitterEngine.shared().authenticatedUsername, andSize: FHSTwitterEngineImageSizeOriginal)
print("profile pic is \(profilepic)")

How to get twitter profile picture in ios?

Have you considered using a 3rd party Twitter engine for this? I've used FHSTwitterEngine with a fair amount of success, and it seems to be under active development.

To pull a profile picture you would do something like this:

[[FHSTwitterEngine sharedEngine]permanentlySetConsumerKey:@"<consumer_key>" andSecret:@"<consumer_secret>"];
[[FHSTwitterEngine sharedEngine]showOAuthLoginControllerFromViewController:self
withCompletion:^(BOOL success) {
if (success) {
UIImage *profileImg = [[FHSTwitterEngine sharedEngine] getProfileImageForUsername:@"<username>" andSize:size];
}
}];
