Using AFNetworking, I'm able to successfully login without any problems and store a session. As soon as I stop debugging in xcode, the simulator is still open but goes to the iphone homescreen. When I go to run the app again from xcode, the login session is gone and user is nil, spent a couple hours and not sure why. My question is is stop debugging messing with the session of the logged in user? Does using setAuthorizationHeaderWithUsername have to do with anything.
#property (retain, nonatomic) NSDictionary* user;
Login:
[[API sharedInstance] commandWithParams:params
onCompletion:^(NSDictionary *json) {
//handle the response
NSDictionary* res = [[json objectForKey:#"result"] objectAtIndex:0];
if ([json objectForKey:#"error"]==nil && [[res objectForKey:#"IdUser"] intValue]>0) {
//success
[[API sharedInstance] setUser:res];
}
}];
API:
+(API*)sharedInstance
{
static API *sharedInstance = nil;
static dispatch_once_t oncePredicate;
dispatch_once(&oncePredicate, ^{
sharedInstance = [[self alloc] initWithBaseURL:[NSURL URLWithString:kAPIHost]];
});
return sharedInstance;
}
You need to serialize your cookies into files or other stores.

I am trying to add Google Drive support to one of my apps using a private app data folder. I have sign-in working with the GIDSignIn class and the scope set to kGTLRAuthScopeDriveAppdata. Once I am signed in, I can create folders and get a file listing that shows the folders are there, then I can delete the folders and the file listing shows that they are gone. But for some reason when I try to upload a file I get a 403 error ("The user does not have sufficient permissions for this file."). This happens whether I try to put the file in the root of the app data folder or into a folder I have created.
I have set up a project in the Google Developer Console. I have an API key configured to work with my app's bundle ID and given it unrestricted API access. The Google Drive API is enabled.
My code is adapted from Google's own samples so a lot of this may look quite familiar. I've trimmed down the sign-in handling since that appears to be working fine.
- (instancetype) init
{
self = [super init];
if (!self) return nil;
[GIDSignIn sharedInstance].clientID = (NSString *)kGoogleClientId;
//kGoogleClientId is the ID from the developer console.
[GIDSignIn sharedInstance].delegate = self;
[GIDSignIn sharedInstance].scopes = #[kGTLRAuthScopeDriveAppdata];
return self;
}
//GIDSignInDelegate method
- (void) signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user withError:(NSError *)error
{
authenticatedUser = user; //authenticatedUser is an instance variable
NSLog(#"Signed in to Google Drive with user %#", user.profile.name);
[delegate GoogleDriveDidSignIn:self];
}
- (GTLRDriveService *) driveService
{
static GTLRDriveService *service;
static dispatch_once_t onceToken;
dispatch_once(&onceToken,
^{
service = [[GTLRDriveService alloc] init];
service.APIKey = (NSString *)kGoogleApiKey;
//kGoogleApiKey matches the developer console too. It has unrestricted API access and is tied to my bundle ID
service.APIKeyRestrictionBundleID = [[NSBundle mainBundle] bundleIdentifier];
service.shouldFetchNextPages = YES;
service.retryEnabled = YES;
});
service.authorizer = authenticatedUser.authentication.fetcherAuthorizer;
//authenticatedUser is an instance variable which stores the user information returned by
//GIDSignIn when the user signs in
return service;
}

}
else
{
NSLog(#"-writeFileAtUrl:toFolderWithId:completionHandler: status code = %li : callbackError: %#", callbackTicket.statusCode, callbackError.localizedDescription);
}
}];
}
As an example, I've tried doing this after GIDSignIn logs in:
NSURL *sampleFile = [[NSBundle mainBundle] URLForResource:#"AValidTestFile" withExtension:#"png"];
if (sampleFile)
{
[self writeFileAtUrl:sampleFile toFolderWithId:#"appDataFolder" completionHandler:^(NSString *filename, NSString *newFileId)
{
NSLog(#"Uploaded file %# with ID %#", filename, newFileId);
}];
}
I still just get a 403 error.
At this point, I've read a huge number of tutorials, blog posts and forum threads in several different programming languages. I've gone over my own code several times and added an insane number of logging statements to double check everything, but I can't work out how I can have permission to create folders, but not to put files in them.
Some time later...
If you go through the credential wizard in the Google Console (rather than just selecting an iOS credential because you're creating an iOS app), you get a message which says "Application data cannot be accessed securely from iOS. Please consider selecting another platform" and it refuses to create a credential for you. Is it possible that this just doesn't work, despite the SDK having the necessary constants?
For those who follow after me, I think I've concluded that using the appDataFolder in iOS just doesn't work.
Having switched to using a folder in the Drive space, I've also found that the -uploadParametersWithFileURL:MIMEType: method of GTLRUploadParameters doesn't work. When I use that I get a file called 'Untitled' (containing the file metadata I set in my GTLRDrive_File object) in the root of the drive. As soon as I switched to -uploadParametersWithData:MIMEType: I got the correct file in the correct place.
I suppose the lesson so far is that if something isn't working, assume it’s the SDK.
I am following the Spotify SDK tutorial, and trying to make a RN module for my application. This is my SpotifyModule.m code:
#import "SpotifyModule.h"
#import "React/RCTLog.h"
#import "React/RCTBridge.h"
#implementation SpotifyModule
RCT_EXPORT_MODULE()
+ (id)sharedManager {
static SpotifyModule *sharedManager = nil;
#synchronized(self) {
if (sharedManager == nil)
sharedManager = [[self alloc] init];
}
return sharedManager;
}
RCT_EXPORT_METHOD(authenticate:(RCTResponseSenderBlock)callback)
{
// Your implementation here
RCTLogInfo(#"authenticate");
self.auth = [SPTAuth defaultInstance];
// The client ID you got from the developer site
self.auth.clientID = #"8fff6cbb84d147e383060be62cec5dfa";
// The redirect URL as you entered it at the developer site
self.auth.redirectURL = [NSURL URLWithString:#"my-android-auth://callback"];
// Setting the `sessionUserDefaultsKey` enables SPTAuth to automatically store the session object for future use.
self.auth.sessionUserDefaultsKey = #"current session";
// Set the scopes you need the user to authorize. `SPTAuthStreamingScope` is required for playing audio.
self.auth.requestedScopes = #[SPTAuthPlaylistReadPrivateScope, SPTAuthUserReadPrivateScope];
//save the login callback
SpotifyModule *spotifyModule = (SpotifyModule *)[SpotifyModule sharedManager];
spotifyModule.loginCallback = callback;
//setup event dispatcher
spotifyModule.eventDispatcher = [[RCTEventDispatcher alloc] init];
[spotifyModule.eventDispatcher setValue:self.bridge forKey:#"bridge"];
// Start authenticating when the app is finished launching
dispatch_async(dispatch_get_main_queue(), ^{
[self startAuthenticationFlow];
});
}
- (void)startAuthenticationFlow
{
// Check if we could use the access token we already have
if ([self.auth.session isValid]) {
// Use it to log in
SpotifyModule *spotifyModule = (SpotifyModule *)[SpotifyModule sharedManager];
NSString *accessToken = self.auth.session.accessToken;
spotifyModule.loginCallback(#[accessToken]);
} else {
// Get the URL to the Spotify authorization portal
NSURL *authURL = [self.auth spotifyWebAuthenticationURL];
// Present in a SafariViewController
self.authViewController = [[SFSafariViewController alloc] initWithURL:authURL];
UIViewController *rootViewController = [UIApplication sharedApplication].delegate.window.rootViewController;
[rootViewController presentViewController:self.authViewController animated:YES completion:nil];
}
}
- (BOOL) application:(UIApplication *)app
openURL:(NSURL *)url
options:(NSDictionary *)options
{
// If the incoming url is what we expect we handle it
if ([self.auth canHandleURL:url]) {
// Close the authentication window
[self.authViewController.presentingViewController dismissViewControllerAnimated:YES completion:nil];
self.authViewController = nil;
// Parse the incoming url to a session object
[self.auth handleAuthCallbackWithTriggeredAuthURL:url callback:^(NSError *error, SPTSession *session) {
if (session) {
// Send auth token
SpotifyModule *spotifyModule = (SpotifyModule *)[SpotifyModule sharedManager];
NSString *accessToken = session.accessToken;
spotifyModule.loginCallback(#[accessToken]); }
}];
return YES;
}
return NO;
}
#end
The way I want to use it from the RN end, is call authenticate, with a callback for the access token. I got this working on Android fine.
Native.authenticate(function(token) {
store.dispatch(actions.loginSuccess(token));
});
On iOS, with the above code, I get to the attached screen, and when clicking Ok I get the following error:
SpotiFind[5475:29641] *** Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '+[SpotifyModule
application:openURL:sourceApplication:annotation:]: unrecognized
selector sent to class 0x10cb406f8'
So from my minimal ObjectiveC understanding, its trying to call a different method, than the one that the tutorial instructs to implement.
Any recommendations on how to make this work ?
If its any relevant, I build against iOS 10, and use the latest Spotify iOS SDK
p.s I realize the name might be against some copyrighting, its just temp for development :)
Thanks to your tips (in the comments), we managed to make our Spotify authentication work with React-native.
We used the code from your Pastebin to create a reusable module so that nobody has to waste time anymore.
You can find the module here: emphaz/react-native-ios-spotify-sdk
There is a tutorial for the setup and we even created a boilerplate project
Thanks a lot Giannis !
I have an in-home app that will be supported by IT team.
When they support desktop apps, they may read logs to find any troubles (like server returned 404 on sync request).
I can use NSLog for iOS, but how can user access them with out of Xcode?
I can't ask any user "please give me your phone to investigate what has happened".
Does there is some tool any IT person with out of Xcode and Mac may use to read iOS logs?
Does there is some tool any IT person with out of Xcode and Mac may use to read iOS logs?
Unfortunately not. It used to be that you could run an app on your device that would read the Console log, but Apple took that ability away; I guess they saw it as a security breach.
If your user can get to a Mac running Xcode, they can view the console log directly in Xcode.
Otherwise, as others have suggested, you will have to build into your app the capacity to keep a log in a place you can get to. For example you can write to a file and then offer (within the app) to email that file to yourself. Many apps have an interface to a facility like this in their Settings bundle.
I've been using the combination of CocoaLumberjack, Antenna & DDAntennalogger at work for remote logging. Basically, you have to set up an end-point at your server and Antenna will be used to send the logs remotely.
Here's the reference that when configuring it on my project:
Remote logging using CocoaLumberjack, Antenna & DDAntennaLogger
This is how you can do it:
Step 1: Redirect your NSLog statements to a text file in file system. This you can do on specific user action or always enable it and delete it periodically.
Step 2: Have a web service which will allow you to upload the saved logs in the file system. You could trigger this on user action or may be a timer based job.
Step 3: Delete the logs from file system once upload is successful.
Here is a example of such a custom logger:
#import "MyCustomLogging.h"
#define kMyCustomLoggingFile #"NSLogging.txt"

#interface MyCustomLogging ()

My question is predicated on Jason Clark’s statement at f8 2014 that app links is designed to sit side by side well with deep linking technologies. I have a word game app published in 2013 to Canada and Australia using Facebook’s authentication but without deep linking. For the US market launch my intent was to add Facebook deep linking. Managed with the request and feed dialogs to send the Match Identifier UUID for both initiating a match and then bragging about the match (FriendSmash example) at that time to open the game on that match. My day job got in the way and I did not have time to finish QA and support a launch to the US. Last summer I upgraded SDKs (Facebook 3.14) and the url query no longer contained the string ‘notif’ to allow me to parse for the match Id. Therefore, I switched from using [FBSession.activeSession handleOpenURL:url] to the current [FBAppCall handleOpenURL:url …] and some other code from the new FriendSmash example. However, the url passed from the Facebook app no longer contains the ‘ref’ and therefore not the ‘notif’ which was the method documented to utilize my deep linking content. I have since updated my project to Facebook iOS SDK 3.21 (predicated in part by other SDKs, e.g. AWS not supporting arm64).
I currently use the following code to send the brag
- (void) sendBrag
{
// This function will invoke the Feed Dialog to post to a user's Timeline and News Feed
// It will attemnt to use the Facebook Native Share dialog
// If that's not supported we'll fall back to the web based dialog.
NSArray *friend = [[NSArray alloc] initWithObjects: bragMatch.opponentFacebookId, nil];
NSString *linkURL = [NSString stringWithFormat:#"http://www.ruleofwords.com/?deeplink_matchno=%#", bragMatch.initiatorMatchNo];
//NSString *linkURL = [NSString stringWithFormat:#"http://www.ruleofwords.com"];
NSString *pictureURL = #"https://pacific-castle-1361.herokuapp.com/rowappicon.png";
NSMutableString *msg = [[NSMutableString alloc]
initWithString:#"Just scored 0 points in Rule of Words. Good luck trying to beat that."];
[msg replaceOccurrencesOfString:#"0" withString:bragMatch.initiatorMatchPoints
options:NSBackwardsSearch range: NSMakeRange(0, [msg length])];
// Prepare the native share dialog parameters
FBLinkShareParams *shareParams = [[FBLinkShareParams alloc] init];
shareParams.friends = friend;
shareParams.link = [NSURL URLWithString:linkURL];
shareParams.name = #"Rule of Words Bragging Rights";
shareParams.caption= msg;
shareParams.picture= [NSURL URLWithString:pictureURL];
shareParams.linkDescription = #"Rule of Words, the contagious photography word social game on iPhone.";
if ([FBDialogs canPresentShareDialogWithParams:shareParams]){
[FBDialogs presentShareDialogWithParams:shareParams
clientState:nil
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error publishing story.");
} else if (results[#"completionGesture"] && [results[#"completionGesture"] isEqualToString:#"cancel"]) {
NSLog(#"User canceled story publishing.");
} else {
NSLog(#"Story published.");
}
}];
} else {
// Prepare the web dialog parameters
NSDictionary *params = #{
#"to": bragMatch.opponentFacebookId,
#"name" : shareParams.name,
#"caption" : shareParams.caption,
#"description" : shareParams.linkDescription,
#"picture" : pictureURL,
#"link" : linkURL
};
// Invoke the dialog
[FBWebDialogs presentFeedDialogModallyWithSession:nil
parameters:params
handler:
^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
if (error) {
NSLog(#"Error publishing story %#.", error);
} else {
if (result == FBWebDialogResultDialogNotCompleted) {
NSLog(#"User canceled story publishing.");
} else {
NSLog(#"Story published.");
}
}}];
}
}
(Aside - In my stepping through the sendBrag code the FBDialogs canPresentShareDialogWithParams always fails so that every time it defaults to a feed dialog. Anyone know what is the state is where the share dialog works? )
Then in my AppDelegate I have…
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
NSLog(#"app is %# and url is %# and sourceApp is %#", application, url, sourceApplication);
// attempt to extract a token from the url
return [FBAppCall handleOpenURL:url
sourceApplication:sourceApplication
fallbackHandler:^(FBAppCall *call) {
// If there is an active session
if (FBSession.activeSession.isOpen) {
// Check the incoming link
[self handleAppLinkData:call.appLinkData];
} else {
NSLog(#"Access Token is %#", call.accessTokenData);
if (call.accessTokenData) {
// If token data is passed in and there's
// no active session.
if ([self handleAppLinkToken:call.accessTokenData]) {
// Attempt to open the session using the
// cached token and if successful then
// check the incoming link
[self handleAppLinkData:call.appLinkData];
}
}
}
}];
- (void) handleAppLinkData:(FBAppLinkData *)appLinkData {
NSURL *targetURL = appLinkData.targetURL;
if (targetURL) {
//NSURL *targetURL = [NSURL URLWithString:targetURLString];
NSDictionary *targetParams = [self parseURLParams:[targetURL query]];
NSString *ref = [targetParams valueForKey:#"ref"];
// Check if ref parm is among incoming news feed link, otw attribution link
if ([ref isEqualToString:#"notif"]) {
// Get the request id
NSString *requestIDParam = targetParams[#"request_ids"];
NSArray *requestIDs = [requestIDParam
componentsSeparatedByString:#","];
// Get data (of last request) from Graph API call to request id endpoint
//
[self notificationGet:requestIDs[[requestIDs count]-1]];
}
}
}
- (void) notificationGet:(NSString *)requestid {
__block NSString *title;
__block NSString *message;
[FBRequestConnection startWithGraphPath:requestid
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
if (! error) {
if (result[#"data"])
{
title = [NSString stringWithFormat:
#"%# requests a match!", result[#"from"][#"name"]];
NSString *jsonString = result[#"data"];
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
if (!jsonData) {
NSLog(#"JSON decode error: %#", error);
return;
}
NSError *jsonError = nil;
NSDictionary *requestData =[NSJSONSerialization JSONObjectWithData:jsonData options:0
error:&jsonError];
if (jsonError) {
NSLog(#"JSON decode error: %#", error);
return;
}
message = [NSString stringWithFormat:#"Match #: %#, Flashes: %#",
requestData[#"deeplink_matchno"],
requestData[#"flashes_gifted"]];
// set global opponentFacebookId for bragging
[[rowGlobals sharedGlobalVars] setRowGlobal:requestData[#"deeplink_matchno"]
forKey:#"deeplink_matchno"] ;
// Set up FB Deep Link Notification
// homeViewController is registered for notification
[[NSNotificationCenter defaultCenter]
postNotificationName:FBDeepLinkNotification
object:requestData[#"deeplink_matchno"]];
NSLog(#"successfully posted DeepLink notification") ;
} else {
title = [NSString stringWithFormat:#"%# sent you a request", result[#"from"][#"name"]];
message = result[#"message"];
}
// Delete the request notification
[self notificationClear:result[#"id"]];
} else {
title = #"General Deep Link Error" ;
message = #"Error occured with Facebook FBRequest Connection. This Facebook notification likely has been previously processed." ;
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:message
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil,
nil];
[alert show];
}];
}
Now I recognize I have some clean up to align the dialog setup with how I parse appLinkData to get the matchId UUID for my NSNotification to open on the game, but I am not getting that far to bother cleaning it up.
I have tried many meta tags on my site but at the moment I am just using
<meta property=”al:ios:url” content=”ruleofwords”>
where ruleofwords is a custom URL I added to my app’s plist.
but I cannot seem to put together any URL other than
NSString *linkURL = [NSString stringWithFormat:#"http://www.ruleofwords.com"];
which will launch my game by clicking on the Facebook link…
When I use anything like
NSString *urlLink = [NSString stringWithFormat:#"https://www.ruleofwords.com/?deeplink_matchNo=%#", bragMatch.initiatorMatchNo];
Then Facebook will only launch my web page without the custom URL link to my game.
Moreover, Facebook no longer launches it directly; it brings up my web page with an added link displayed as the offset brackets app Links logo.(Although not explicit it does technically follow the Facebook flow diagram). Touching this app Link logo does launch my game. This seems to be the case whether I have the meta tag on my website or not (now I may have other problems since we are only using Godaddy website builder).
Previously with the request dialog I had the ability to populate values such as #”data” with things like my match Id and gifts
NSData *jsonData = [NSJSONSerialization
dataWithJSONObject:#{
#"deeplink_matchno": bragMatch.initiatorMatchNo,
#"flashes_gifted": #"0"}

However, I no longer have al_applink_data in the passed URL for this request dialog, it just has an access_token with the original custom URL.
url is fb407545862655947://authorize/#access_token=CAAFyqSpfj8sBAGxahmdTCl1D9fs5hZBt3OfKP2MHCtM8STHadqEjlyFnXDTNHScjsxZCI6q0H8ZAppNSqJIJt83uN4LemkfklLjOdPTv3JZBtg3xTVZBKOhzdOMaZCGob5x2FPddZBzmaZBhIaE8dIgNqPfi9IlEuwQ2oHq6tEgA1w1pNESnHuDyK9gD7vswAC93nO7cCmCT4KBgxI22UDB3nINYZA058g8AZD&expires_in=3600 and sourceApp is com.facebook.Facebook
When I add the #”data” param with
[FBWebDialogs presentFeedDialogModallyWithSession:…]
although this argument is accepted by the feed dialog I the url does not get my match UUID or anything extra from my #”data” param…
url is ruleofwords:///?al_applink_data=%7B%22target_url%22%3A%22http%3A%5C%2F%5C%2Fwww.ruleofwords.com%5C%2F%22%2C%22extras%22%3A%7B%22fb_ref%22%3A%22Default%22%7D%2C%22referer_app_link%22%3A%7B%22url%22%3A%22fb%3A%5C%2F%5C%2F%5C%2F%3Fbacktrack_id%3Ddlr5p6iu_6a-OeUn%22%2C%22app_name%22%3A%22Facebook%22%7D%7D and sourceApp is com.facebook.Facebook
So I am at a loss how I am supposed to inject content specific information so that I can open my game with the match, which the opponent has requested or bragged about. I probably would have given up a long time ago but I did once have deep linking working (SDK 3.5?). I am wondering if I should be at another release level of the SDK for deep linking. It seems like the Facebook platform has significantly changed how it packages appLinkData. And although Facebook’s documentation has improved over the past two years, many of the examples which are required to put this all together do not seem to be referring to the same level of SDK. So Facebook how do I inject content into appLinkData so I can support deep linking with SDK 3.21? I thought about adding the Bolts framework but Jason implied it was designed for outlinking apps, which is not my case.
I can directly type in my iPhone Safari something like ‘ruleofwords://matchId=UUID’ and get the app delegate to parse out the [url query] so I could probably implement deep linking with push notifications, but I still like the ability to have a Facebook user tap on a link and launch the specific match directly.
I use a facebook api to connect to facebook and send request via native dialogs provided by the api.
I followed the sample posted in the docs on developers.facebook.com
But I have following problem sending requests :
1. The requests are not shown in notifications - only in application center - In this case i think that it is a problem of that the app is in sandbox and not posted to APPSTORE
I succesfully send request to facebook server with right fbUser id. But when I want to receive the notification in app here comes the problem :
Following the docs as an authorized user I should se
this in open url method:
fb[APP_ID]://authorize#expires_in=[ACCESS_TOKEN_EXPIRATION]
&access_token=[USER_ACCESS_TOKEN]
&target_url=https://apps.facebook.com/[APP_NAME_SPACE]/?request_ids=
[COMMA_SEPARATED_REQUESTIDs]&ref=notif&app_request_type=user_to_user
But i can see only plain login without targer url .... I can see session expiration date, fb app id, access token and so on. But no target url?
So basically what the target_url is?
How it should be set?
What i have to include when sending request?
In addition :
application handle open url method is called properly.
checkRequests method is also called properly after app becomes active.
Please do not link me to the docs. I have read it moreless 50 times and didn't find any reasonable solution...

Is there any way that these problems are caused by the way that the app is not published on Appstore (Appstore id is not set neither for iPhone nor iPad)?
Here are code snippets showing using of the fb api:
Thank you very much for the time.
