How to integrate FitBit Api in IOS app using Swift

问题:

First of all I created an account at https://www.fitbit.com Then I careated an app at https://dev.fitbit.com then installed OAuthSwift using cocoa pods and implemented this method in my AppDelegate

    func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
    if (url.host == "oauth-callback") {
        OAuthSwift.handleOpenURL(url)
    }
    return true
}

now i want to get the data (Name, Steps taken etc) of user account I created at https://www.fitbit.com how can I do that ? I searched but was not able to find any tutorial on fitbit integration. And where to use this information in my code? So please guide me about next step what should I do to get the data.

FitBit work with OAuth 2.0 API which require Client ID and Secret key. You need these client id and secret key to authenticate with OAuth 2.0 API. There is a blog post related to FitBit integration in iOS with Swift. Lets checkout and learn "How to implement fitbit in iOS" https://appengineer.in/2016/04/30/fitbit-aouth-in-ios-app/

ex:

let oauthswift = OAuth2Swift(
        consumerKey:    fitbit_clientID,
        consumerSecret: fitbit_consumer_secret,
        authorizeUrl:   "https://www.fitbit.com/oauth2/authorize",
        accessTokenUrl: "https://api.fitbit.com/oauth2/token",
        responseType:   "token"
    )

Any chance you could do it with basic auth as opposed to OAuth? I had a similar problem trying to POST to MailGun for some automated emails I was implementing in an app.

I was able to get this working properly with a large HTTP response. I put the full path into Keys.plist so that I can upload my code to github and broke out some of the arguments into variables so I can have them programmatically set later down the road.

// Email the FBO with desired information
// Parse our Keys.plist so we can use our path
var keys: NSDictionary?

if let path = NSBundle.mainBundle().pathForResource("Keys", ofType: "plist") {
    keys = NSDictionary(contentsOfFile: path)
}

if let dict = keys {
    // variablize our https path with API key, recipient and message text
    let mailgunAPIPath = dict["mailgunAPIPath"] as? String
    let emailRecipient = "[e-mail]"
    let emailMessage = "Testing%20email%20sender%20variables"

    // Create a session and fill it with our request
    let session = NSURLSession.sharedSession()
    let request = NSMutableURLRequest(URL: NSURL(string: mailgunAPIPath! + "from=FBOGo%20Reservation%20%3Cscheduler@<my domain>.com%3E&to=reservations@<my domain>.com&to=\(emailRecipient)&subject=A%20New%20Reservation%21&text=\(emailMessage)")!)

    // POST and report back with any errors and response codes
    request.HTTPMethod = "POST"
    let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
        if let error = error {
            print(error)
        }

        if let response = response {
            print("url = \(response.URL!)")
            print("response = \(response)")
            let httpResponse = response as! NSHTTPURLResponse
            print("response code = \(httpResponse.statusCode)")
        }
    })
    task.resume()
}

The Mailgun Path is in Keys.plist as a string called mailgunAPIPath with the value:

https://API:key-<my key>@api.mailgun.net/v3/<my domain>.com/messages?

Hope this helps!
