In my iOS app i am trying to fetch details of a file stored in dropbox on click of button.
I am trying to choose a file from dropbox and redirect back to my application using DBChooser. It works fine when a user is already logged in the Dropbox.
-(void)choose{
[[DBChooser defaultChooser] openChooserForLinkType:DBChooserLinkTypeDirect fromViewController:self
completion:^(NSArray *results)
{
if ([results count]) {
_result = results[0];
link = [NSString stringWithFormat:#"%#", _result.link];
name = _result.name;
size = [NSString stringWithFormat:#"%lld", _result.size];
icon = [NSString stringWithFormat:#"%#", _result.iconURL];
} else {
_result = nil;
[[[UIAlertView alloc] initWithTitle:#"CANCELLED" message:#"user cancelled!"
delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil]
show];
}
}];
}
Also i have following function in Appdelegate.m
-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:
(NSString *)sourceApplication annotation:(id)annotation
{
if ([[DBChooser defaultChooser] handleOpenURL:url]) {
// This was a Chooser response and handleOpenURL automatically ran the
// completion block
return YES;
}
return NO;
}
Problem starts when user is not logged in and when i click on button it opens dropbox and asks me to enter credentials. After successful logged in, i am able to view my dropbox data, but i am not able to choose anything i.e. on clicking an image it should redirect me back to my aplication, instead it is opening that image in dropbox itself. This happens only when user is not logged in.
I have set the URL schemes for the DropIns used for chooser. I just need to verify if user is logged in the dropbox before calling the choose function. Please help i am stuck on this.

I am using Dropbox and Google Drive integration in my iOS app. I can fetch files from both drives and view listing in tableview. However, when I delete the app on my iPhone without logout from these drives, it still shows logged in when I install new app. How to logout user when I delete the app or remove session?
For Dropbox i am using ObjectiveDropboxOfficial apiV2 and for Google Drive i am using GoogleAPIClientForREST, GTMSessionFetcher etc libraries.
My code:
[DBClientsManager setupWithAppKey:#"my-key"];
[DBClientsManager authorizeFromController:[UIApplication sharedApplication]
controller:self openURL:^(NSURL *url) {
[[UIApplication sharedApplication] openURL:url];
}];
//AppDelegate
if ([DBClientsManager handleRedirectURL:url])
{
if (DBClientsManager.authorizedClient || DBClientsManager.authorizedTeamClient) {
// NSLog(#"App linked successfully!");
// At this point you can start making API calls
NSNotification *notification = [NSNotification notificationWithName:#"DropboxLoggedIn" object:nil];
[[NSNotificationCenter defaultCenter] postNotification:notification];
}
return YES;
}
If these services are designed this way I assume they save credentials in keychain which persists data and your application is already logged in when reinstalled or keychain is anyhow transfered.
If this is not your desired effect I can only assume you will need to log out from these services manually. This means you will need to track these logins and logouts and then when the app starts simply log out from all services which have not been tracked as logged in by you.
It is an ugly thing to do but it is a solution:
When a service is logged in save a value in user defaults
- (void)serviceDidLogin:(ServiceType)type {
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:[self keyForServiceType: type]];
}
Then when it is logged out you need to clear it
- (void)serviceDidLogout:(ServiceType)type {
[[NSUserDefaults standardUserDefaults] removeObjectForKey:[self keyForServiceType: type]];
}
Then when app starts you need to log out from all of the services that you have no recording of being logged into:
- (void)logOutFromAllUnusedService {
for(int i=0; i<ServiceTypeCount; i++) {
ServiceType type = i;
if([[NSUserDefaults standardUserDefaults] boolForKey:[self keyForServiceType: type]] == NO) {
[self logoutFromService:type];
}
}
}
No matter how you do this but my situation assumes ServiceType is an enum like so:
typedef enum {
// Never assign values to enums
ServiceTypeDropbox,
ServiceTypeGoogleDrive,
ServiceTypeCount, // Always last of the valid
// Move deprecated services here
ServiceTypeDeprecated1 // TODO: remove at some point
} ServiceType;
FBSDKSharingDelegate callback is not working. I can post to facebook fine with the ios SDK, but I'd like to detect if the post was successful and take additional action to notify the user. However, the callback is not working for me. The delegate methods are not being called and I don't know why.
Using ios8, Parse as my backend. In Parse, the user is linked to FB. I'm using the IOS simulator.
What I've tried:
I've ensured that publish permissions are granted, saved, and linked to the Parse user. I've run a check and "publish_actions" are detected OK. The posting works fine as I can see the post on the facebook account. It's just the callback that is not working. I've checked my fb setup and it looks fine. For good measure at the very bottom I've included that relevant code from my app delegate. I've blocked out confidential keys with XXXX.
Code:
1st: See if user is logged in to Parse, if not, send to sign in and link to facebook account. Once that is done, I request "publish" permissions and link that additional permission to the Parse user. I know this works b/c when I recompile, it remembers the "publish" permissions and goes right to into the post.
#interface FacebookAPIPost () <FBSDKSharingDelegate>

-(void)shareSegmentFacebookAPI { //if statement below

PFUser *currentUser = [PFUser currentUser];
if(!currentUser) {
[self pushToSignIn];
} else if(![PFFacebookUtils isLinkedWithUser:currentUser]){

}
else {

//Send the facebook status update
[self shareSegmentWithFacebookComposer];
}
}];
}
-(void)shareSegmentWithFacebookComposer{
if ([[FBSDKAccessToken currentAccessToken] hasGranted:#"publish_actions"]) {
[self publishFBPost]; //publish

withPublishPermissions:#[ #"publish_actions"]
block:^(BOOL succeeded, NSError *error) {
if (succeeded) {
NSLog(#"User now has read and publish permissions!");
[self publishFBPost];
}
}];
Here is where the post gets made:
-(void) publishFBPost{
FBSDKShareLinkContent *content = [FBSDKShareLinkContent new];
content.contentURL = [NSURL URLWithString:[self.selectedSegment valueForKey:#"linkToContent"]];
content.contentTitle = [self.selectedProgram valueForKey:#"programTitle"];
content.contentDescription = [self.selectedSegment valueForKey:#"purposeSummary"];
PFFile *theImage = [self.selectedSegment valueForKey:#"segmentImage"];
NSString *urlString = theImage.url;
NSURL *url = [NSURL URLWithString:urlString];
content.imageURL = url;
FBSDKShareDialog *shareDialog = [FBSDKShareDialog new];
[shareDialog setMode:FBSDKShareDialogModeAutomatic];
// [FBSDKShareDialog showFromViewController:self.messageTableViewController withContent:content delegate:self];
[shareDialog setShareContent:content];
[shareDialog setDelegate:self];
[shareDialog setFromViewController:self.messageTableViewController];
[shareDialog show];
}
Delegate methods below are not working. Meaning after the post is complete, I can see it on the FB account, but none of these delegate methods execute.
#pragma mark - delegate methods
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results {

I think I am too late answering this question but someone else could trap into this as well, that's why sharing my knowledge.
As per Facebook API documentation
sharer:didCompleteWithResults: Sent to the delegate when the share completes without error or cancellation.
The results from the sharer. This may be nil or empty.
its probably because this delegate method is only get called when the post is successfully shared. In case of failure the other delegate method sharer:didFailWithError:get called. I think Facebook API should not need to add the result parameter is that case.
So in my experience if sharer:didCompleteWithResults whenever this is called that would mean success.
I'm trying to authenticate users through facebook. I've read the SDK and done every necessary things that need to be done, BUT if I try to Login into my app while LoggedIn in this place,
It Tells me SESSION CLOSED but if I logged out and try to SIgnIn into my app, it checks if I've the facebook app and try to check if logged in if I'm, it updates and do what I want it to do, but if I'm not, it brings a Dialog for me to login. But, once I sign into the Image above, the other thing happens CLOSED SESSION ERROR. Would appreciate the help, thanks.

I add a similar problem, in my case I found the reason, I was using an application id that was not correct (because of test environment/production environment configuration of my app, I was developing and I had no facebook app for the development application id).
I'm sharing my approach for debugging the problem:
just launch the app from xcode, put a break point where the error is intercepted (CordovaFacebook.m) and there if you are lucky you should see a better description of the problem
Furthermore, remember to set the correct fb app id inside .plist
remember also that if you are using a test application on facebook, that application should be either publicly available or you should set some test users inside the ROLES tab of the admin section
Another source of interesting debugging informations is the following:
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
if (!url) {
return NO;
}
set a break point there and inspect the url variable content.
I have used the following code to fetch data from the Facebook to my app.
I have did all the other stuff in app delegate and plist.
This sometimes works and fetched data and sometimes don't. Can anyone help me with this. I can't figure what the problem is!
- (IBAction)facebook:(id)sender
{
FBLoginView *loginView=[[FBLoginView alloc]init];
loginView.delegate=self;
loginView.readPermissions = #[#"first_name",
#"last_name",
#"location",
#"id",
#"access_token"];
NSArray* permissions = [NSArray arrayWithObjects: #"email", nil];
loginView.readPermissions=permissions;
[FBSession openActiveSessionWithAllowLoginUI:YES];
[FBRequestConnection
startForMeWithCompletionHandler:^(FBRequestConnection *connection,
id<FBGraphUser> user1,
NSError *error) {
if (!error) {
firstname=user1.first_name;
lastname=user1.last_name;
city=[user1.location objectForKey:#"name"];
email=user1[#"email"];
fbid=user1.id;
Loggedin=#"Y";
[[NSUserDefaults standardUserDefaults]setObject:Loggedin forKey:#"token"];
[[NSUserDefaults standardUserDefaults]synchronize];
}
if (![fbid isEqualToString:#""])
{
[self performSegueWithIdentifier: #"Facebooksegue" sender: self];
}
NSLog(#"%#",firstname);
NSLog(#"%#",lastname);
NSLog(#"%#",city);
NSLog(#"%#",email);
NSLog(#"%#",fbid);
}];
}
My AppDelegate
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
// attempt to extract a token from the url
return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[FBSession class];
return YES;
}
I had a similar situation and I had used almost the same code as you did.
My problem was with the test Facebook id which I had used. I hadn't had it verified so it didn't respond with the email. Try using another account and it might work. If not check whether your app is authorized with the Facebook account synchronized with your account in the settings.
Hope this helps.
Go to the blue project icon at the top left, select your target, go to build settings, find other linker flags, add -ObjC. This will make it so that the entire framework gets statically linked and thus you can reference FBLoginView in the storyboard successfully.
I have a web browser app with a URL Identifier/Scheme "wb".
ok, when the user typing wb:// in safari, my app will open. Perfect!
but, if the user typing "wb://www.facebook.com" in safari, I want to open "facebook.com" in my app.
How do i get the link after the "wb://" ?
I'm using (This:) in my AppDelegate.m :
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
// Display text
UIAlertView *alertView;
NSString *text = [[url host] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
alertView = [[UIAlertView alloc] initWithTitle:#"Text:" message:text delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
return YES;
}
and get the link when the users types the link.
but how did I get it to my ViewController.m so i can load my webview with the text.
You could provide an implementation for application:handleOpenUrl: in your AppDelegate like:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
// Do whatever is needed with the provided url
}
