I'm building SDK for my product and there will be no app delegate class. I used Dropbox Integration in my SDK, so I'm bound to use following method.
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
NSString *stringUrl = [url absoluteString];
if ([stringUrl containsString:#"cancel"]) {
// Handle if user cancelled the login
[[NSNotificationCenter defaultCenter] postNotificationName:#"dropboxRegistrationCancel" object:self];
return NO;
}
if ([[DBSession sharedSession] handleOpenURL:url]) {
if ([[DBSession sharedSession] isLinked]) {
NSLog(#"App linked successfully!");
// At this point you can start making API calls
[[NSNotificationCenter defaultCenter] postNotificationName:ApplicationComeBackFromDropBoxLoginPage object:self];
}
return YES;
}
// Add whatever other url handling code your app requires here
return NO;
}
So Issue is there is no app delegate than how can use above method?
Or any alternate solution for this to use this in another class (like to inherit UIResponder class).
Looking for help.
If you are building a SDK with no appDelegate, then well, you have nothing to do. It will be in your project where you will be using your sdk that you will have to add this line.
By the way, the line NSString *stringUrl = [url absoluteString]; is absolutly useless since you are not using stringUrl later on, and the
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
// NSString *stringUrl = [url absoluteString];
return YES;
}
just means: yes you can quit my app to open another app when the user click on a link.
No biggy....

My application has the following steps:
Send file with own extension to user's email
When file is opened, the app is started (after user has select it)
Now I want to use the data from the file.
But how?
I added following function to my AppDelegate.m file in Xcode.
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
if (url){
NSString *information = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];
UIViewController *rootViewController = [UIViewController new];
//this is not the way to display this on the screen
NSLog(#"The file contained: %#",information);
}
return YES;
}
Is it possible to use this information string in react-native? What do I need to add to use it as 'this.props.information' in my react-native app?
i have implemented google play games in my app for leaderboard.
my requirement is to display info Alert when user login first time in safari(redirect to safari automatically for login)
i have written this code
[GPGManager sharedInstance].statusDelegate = self;
BOOL isSignedIn = [[GPGManager sharedInstance] signInWithClientID:kGoogleClient silently:flag];
NSLOG(#“is signedin %d",[GPGManager sharedInstance].isSignedIn);
but every time [GPGManager sharedInstance].isSignedIn this variable returns false.
any one have any idea ??
You must configure the GGLContext shared instance. You can do this in many places in your app. Often the easiest place to configure this instance is in your app delegate's application:didFinishLaunchingWithOptions: method.
In your app delegate's .h file, declare that this class implements the GIDSignInDelegate protocol.
#import <Google/SignIn.h>
#interface AppDelegate : UIResponder <UIApplicationDelegate, GIDSignInDelegate>
AppDelegate.h
In your app delegate's application:didFinishLaunchingWithOptions: method, configure the GGLContext shared instance and set the sign-in delegate.
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSError* configureError;
[[GGLContext sharedInstance] configureWithError: &configureError];
NSAssert(!configureError, #"Error configuring Google services: %#", configureError);
[GIDSignIn sharedInstance].delegate = self;
return YES;
}
Implement the application:openURL:options: method of your app delegate. The method should call the handleURL method of the GIDSignIn instance, which will properly handle the URL that your application receives at the end of the authentication process.
- (BOOL)application:(UIApplication *)app
openURL:(NSURL *)url
options:(NSDictionary *)options {
return [[GIDSignIn sharedInstance] handleURL:url
sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
}
In the app delegate, implement the GIDSignInDelegate protocol to handle the sign-in process by defining the following methods:
- (void)signIn:(GIDSignIn *)signIn
didSignInForUser:(GIDGoogleUser *)user
withError:(NSError *)error {
// Perform any operations on signed in user here.
NSString *userId = user.userID; // For client-side use only!
NSString *idToken = user.authentication.idToken; // Safe to send to the server
NSString *fullName = user.profile.name;
NSString *givenName = user.profile.givenName;
NSString *familyName = user.profile.familyName;
NSString *email = user.profile.email;
// ...
}
- (void)signIn:(GIDSignIn *)signIn
didDisconnectWithUser:(GIDGoogleUser *)user
withError:(NSError *)error {
// Perform any operations when the user disconnects from app here.
// ...
}
i have implemented URL Scheme in my App so that whenever i click the URL, it will open up my app. I have also inserted some request in the URL such as
Yuvtime//:?registerName=Puppy&Passwords=67825
and i use the openUrl in AppDelegate to handle the processing of the URL and pass the data (registerName=Puppy&Passwords=67825`) to my rootViewController which is the registration page of my app, the code is as shown below.
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{
// Check the calling application Bundle ID
if ([[url scheme] isEqualToString:#"yuvitime"])
{
NSLog(#"Calling Application Bundle ID: %#", sourceApplication);
NSLog(#"URL scheme:%#", [url scheme]);
self.yuvitimeRequest = [url query];
NSLog(#"URL query: %#", yuvitimeRequest);
return YES;
}
else
return NO;
}
And in the RegistrationviewController, I implemented the code as follows.
-(void)viewWillAppear:(BOOL)animated{
[super viewDidAppear:animated];
AppDelegate * myAppDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
self.requestFromURL = myAppDelegate.yuvitimeRequest;
NSLog(#"%# hello google", self.requestFromURL);
if (self.requestFromURL.length > 0){
self.isRequestFromURL = YES;
}
if(self.isRequestFromURL == YES){
self.mainViewController.joinRoomName = self.requestFromURL;
self.isRequestFromURL = NO;
self.requestFromURL = #"";
[self presentViewController:self.mainViewController animated:YES completion:nil];
}
}
However, the problem i encounter is that:
If the user already has its app opened, this viewWilAppear in the RegistrationViewController will not be called again, so the data will not be passed automatically from the URL. (Only by killing the app, and click the URL will the data be passed as what we initially desired).
I also understand that when an App is already open and called again, only
(void)applicationWillEnterForeground:(UIApplication *)application &
(void)applicationDidBecomeActive:(UIApplication *)application
will be called in sequence in the app delegate. But somehow i stuck on how do i pass data to my registrationViewController from these two methods and if i can manage to do it in these two application methods, that would mean that my app checks every time on whether there is any registration data available from URL when the app comes to the foreground.
Since we already have the
(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
to handle the URL scheme, is it possible that we only check once without using the foreground and didBecomeActive app delegate functions when we click the URL?
EDIT: After implementing URL scheme, whenever you click a URL, a delegate method in AppDelegate.m will be triggered.
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation;
This is also the function that will enable us to process the URL in our app and pass it around to other viewControllers.
I was kinda thinking, is there a way that we can implement a notification/function such that only when this openURL function is called, we then call the triggerURL function in registrationViewController.
Just out of curiosity!
Thanks
Regards
In your RegistrationViewController, you can register for UIApplicationDidBecomeActiveNotification and get notified of application being awakened even when your view controller was already loaded.
Add this line in your loadView:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(triggerURL) name:UIApplicationDidBecomeActiveNotification object:[UIApplication sharedApplication]];
This will allow the function updateSettings to be called every time your app wakes. Also remember to remove this listener at the end by:
[[NSNotificationCenter defaultCenter] removeObserver:self];
in your dealloc method.
Post that, this is how your viewWillAppear & triggerURL will look like:
- (void)viewWillAppear:(BOOL)animated{
[super viewDidAppear:animated];
[self triggerURL];
}
- (void)triggerURL {
AppDelegate * myAppDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
self.requestFromURL = myAppDelegate.yuvitimeRequest;
NSLog(#"%# hello google", self.requestFromURL);
if (self.requestFromURL.length > 0){
self.isRequestFromURL = YES;
}
if(self.isRequestFromURL == YES){
self.mainViewController.joinRoomName = self.requestFromURL;
self.isRequestFromURL = NO;
self.requestFromURL = #"";
[self presentViewController:self.mainViewController animated:YES completion:nil];
}
}
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>
#end
#implementation FacebookAPIPost
-(void)shareSegmentFacebookAPI { //if statement below
//1) logged in?, if not send to sign up screen
//2) else if logged in, link account to facebook account, then send post
//3) else send to post b/c signed up and linked already.
PFUser *currentUser = [PFUser currentUser];
if(!currentUser) {
[self pushToSignIn];
} else if(![PFFacebookUtils isLinkedWithUser:currentUser]){
[self linkUserToFacebook:currentUser];
NSLog(#"user account not linked to facebook");
} else {
[self shareSegmentWithFacebookComposer];
}
}
-(void)linkUserToFacebook:currentUser{
[PFFacebookUtils linkUserInBackground:currentUser withPublishPermissions:#[#"publish_actions"] block:^(BOOL succeeded, NSError *error) {
if(error){
NSLog(#"There was an issue linking your facebook account. Please try again.");
}
else {
NSLog(#"facebook account is linked");
//Send the facebook status update
[self shareSegmentWithFacebookComposer];
}
}];
}
-(void)shareSegmentWithFacebookComposer{
if ([[FBSDKAccessToken currentAccessToken] hasGranted:#"publish_actions"]) {
[self publishFBPost]; //publish
} else {
NSLog(#"no publish permissions"); // no publish permissions so get them, then post
[PFFacebookUtils linkUserInBackground:[PFUser currentUser]
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 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.
