I can't tell why the setInitialText function isn't working in my implementation of SLServiceTypeFacebook. The code I used for Facebook and Twitter are nigh identical except where Facebook replaces the word Twitter, and twitter works just fine. Any help appreciated.
Thanks
if ([buttonTitle isEqualToString:#"Facebook"]){
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
SLComposeViewController *faceSheet = [[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook] init];
NSLog(#"%#", messageField.text);//This returns the appropriate string
[faceSheet setInitialText:messageField.text];
//The facebook VC appears, but initial text is not set to messageField.text
[self presentViewController:faceSheet animated:YES completion:nil];
}
}
This certainly is a strange issue, and see as I don't see anything else obviously wrong with this, so here's my suggestion. It is possible that somehow something's getting messed up due to the extraneous initializer you have set on the composer. composeViewControllerForServiceType: already alloc/init's an instance of SLComposeViewController, so there is no need to add init. Replace this:
SLComposeViewController *faceSheet = [[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook] init];
With this line:
SLComposeViewController *faceSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
This is not an issue, Facebook doesn't allow it anymore.Facebook changes its platform privacy policy for share feature. Use below link for reference

I recently integrated the Google + API in my App, it was a breeze, my only problem with it, is that everything requires you to leave the app and then come back (it uses URL schemes for this). This is not the behavior I would like, is there a way to directly call their services and do whatever I want with the responses just like in LinkedIn API?.
I really want to avoid going back and forth between safari and my app. Any suggestions/documentation is appreciated.
Thank you,

UPDATE FROM GOOGLE
today, we released a new Google Sign In iOS SDK with full built-in
support for Sign In via WebView:
developers.google.com/identity/sign-in/ios The SDK supports dispatch
to any of a number of Google apps handling Sign In when present, with
WebView fallback after. In all cases, the Safari switch is avoided,
which we've seen to be the key element in avoiding app rejection.
We're looking forward to getting feedback from people using the new
SDK, and hope its use can replace the (ingenious and diligent)
workarounds people have implemented in the meantime.
THE METHOD BELLOW IS NO LONGER NEEDED
THIS METHOD HANDLES THE LOGIN INTERNAL WITH A CUSTOM UIWebView
THIS WORKS AND WAS APPROVED BY APPLE
My app got kicked from review cause of this
"The app opens a web page in mobile Safari for logging in to Google plus,
then returns the user to the app. The user should be able log in without opening
Safari first."
See this link https://code.google.com/p/google-plus-platform/issues/detail?id=900
I did solved it by following steps
1) create a subclass of UIApplication, which overrides openURL:
.h
#import <UIKit/UIKit.h>
#define ApplicationOpenGoogleAuthNotification #"ApplicationOpenGoogleAuthNotification"
#interface Application : UIApplication
#end
.m
#import "Application.h"
#implementation Application
- (BOOL)openURL:(NSURL*)url {
if ([[url absoluteString] hasPrefix:#"googlechrome-x-callback:"]) {
return NO;
} else if ([[url absoluteString] hasPrefix:#"https://accounts.google.com/o/oauth2/auth"]) {
[[NSNotificationCenter defaultCenter] postNotificationName:ApplicationOpenGoogleAuthNotification object:url];
return NO;
}
return [super openURL:url];
}
#end
this will basically prevent anything to be opened from Chrome on iOS
we catch the auth call and redirect it to our internal UIWebView
2) to info.plist, add the Principal class, and for it Application (or whatever you named the class)
Add plist key "NSPrincipalClass" and as the value the class of your main application (class which extends UIApplication, in this case Application (see code above))
3) catch the notification and open an internal webview
When your custom Application class sends ApplicationOpenGoogleAuthNotification, listen for it somewhere (in the AppDelegate maybe) and when you catch this notification, open a UIWebView (use the URL passed by the notification as the url for the webview) (in my case the LoginViewController listens for this notification and when received, it opens a view controller containing only a webview hooked up to delegate)
4) inside the webview
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if ([[[request URL] absoluteString] hasPrefix:#"com.XXX.XXX:/oauth2callback"]) {
[GPPURLHandler handleURL:url sourceApplication:#"com.google.chrome.ios"n annotation:nil];
// Looks like we did log in (onhand of the url), we are logged in, the Google APi handles the rest
[self.navigationController popViewControllerAnimated:YES];
return NO;
}
return YES;
}
or simmilar code, that handles the response
com.XXX.XXX:/oauth2callback from code above, replace with your company and app identifier, like "com.company.appname:/oauth2callback"
you might want to use #"com.apple.mobilesafari" as sourceApplication parameter
So, it depends what you want to do.
Sign-In: this will always call out to another application. If the Google+ application is installed it will call out to that, else it will fall back to Chrome and Safari.
Sharing/Interactive Posts: right now this always uses Chrome or Mobile Safari.
Retrieving friends, writing app activities, retrieving profile information: All this is done with the access token retrieved after sign in, so does not require leaving the application.
It is possible, though rather unsupported, to skip the SDK and pop up a UIWebView, construct the OAuth link dynamically and send the user to that (take a look at GTMOAuth2ViewControllerTouch in the open source libraries that ship with the SDK). Below is the a very rough example of the kind of thing you could do to plumb it back into the GPPSignIn instance.
However, you would be guaranteeing that the user has to enter their username and password (and maybe 2nd factor). With the Google+ app you're pretty much guaranteed to be already signed in, and with the Chrome/Safari route, there is a chance the user is already signed in (particularly if they're using other apps with Google+ Sign-In).
This also doesn't address sharing, so I would strongly recommend using the existing SDK as far as possible. Filing a feature request for the way you would prefer it to work would be a good thing to do as well: https://code.google.com/p/google-plus-platform/issues/list
#interface ViewController() {
GTMOAuth2ViewControllerTouch *controller;
}
#end;
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
GPPSignIn *signIn = [GPPSignIn sharedInstance];
signIn.clientID = #""; // YOUR CLIENT ID HERE.
signIn.delegate = self;
}
- (IBAction)didTapSignIn:(id)sender {
void (^handler)(id, id, id) =
^(GTMOAuth2ViewControllerTouch *viewController,
GTMOAuth2Authentication *auth,
NSError *error) {
[self dismissViewControllerAnimated:YES completion:^{
[controller release];
}];
if (error) {
NSLog(#"%#", error);
return;
} else {
BOOL signedIn = [[GPPSignIn sharedInstance] trySilentAuthentication];
if(!signedIn) {
NSLog(#"Sign In failed");
}
}
};
controller = [[GTMOAuth2ViewControllerTouch
controllerWithScope:kGTLAuthScopePlusLogin
clientID:[GPPSignIn sharedInstance].clientID
clientSecret:nil
keychainItemName:[GPPSignIn sharedInstance].keychainName
completionHandler:handler] retain];
[self presentViewController:controller animated:YES completion:nil];
}
- (void)finishedWithAuth:(GTMOAuth2Authentication *)auth
error:(NSError *)error {
if (!error) {
UIAlertView * al = [[UIAlertView alloc] initWithTitle:#"Authorised"
message:#"Authorised!"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[al show];
[al release];
}
}
The only real trick to this code is that it uses the [GPPSignIn sharedInstance].keychainName - this means that the auth tokens get stored in the same keychain entry as the GPPSignIn button would, which in turn means we can use [[GPPSignIn sharedInstance] trySilentAuthentication] once it has been populated, and keep the same callback based flow as the main library.
#PeterLapisu approach works good if the Google Plus App is not installed.
Then outgoing url prefixes from app are as follows:
#"googlechrome-x-callback:"
#"https://accounts.google.com/o/oauth2/auth"
However if the Google App is installed there is one more outgoing url and the prefix list looks as follows:
#"com.google.gppconsent.2.4.1:"
#"googlechrome-x-callback:"
#"https://accounts.google.com/o/oauth2/auth"
So, if the Google App is installed, it will be launched simultaneously with our app UIViewController that contains webview.Then if user sucessfully logs in with Google App he will be directed back to our app and the ViewController will be visible.
To prevent this Google App should be allowed to login user and direct him back to our app. According to this discussion: https://code.google.com/p/google-plus-platform/issues/detail?id=900 it is allowed by Apple.
So in my implementation firstly I am checking if the Google App is installed:
- (BOOL)openURL:(NSURL*)url {
NSURL *googlePlusURL = [[NSURL alloc] initWithString:#"gplus://plus.google.com/"];
BOOL hasGPPlusAppInstalled = [[UIApplication sharedApplication] canOpenURL:googlePlusURL];
if(!hasGPPlusAppInstalled)
{
if ([[url absoluteString] hasPrefix:#"googlechrome-x-callback:"]) {
return NO;
} else if ([[url absoluteString] hasPrefix:#"https://accounts.google.com/o/oauth2/auth"]) {
[[NSNotificationCenter defaultCenter] postNotificationName:ApplicationOpenGoogleAuthNotification object:url];
return NO;
}
}
return [super openURL:url];
}
EDIT:
Now I can confirm that my app was finally approved with this solution.
I hope it will help somebody.
It merges Google+ and Gmail samples and completely avoids using Google SignIn Button, i.e you do not leave the app.
Add both Google+ and Gmail API to you Google project, in your app login to google as you would to gmail using GTMOAuth2ViewControllerTouch.xib from OAuth2 and set scope to Google+:
-(IBAction)dologin{
NSString *scope = kGTLAuthScopePlusLogin;//Google+ scope
GTMOAuth2Authentication * auth = [GTMOAuth2ViewControllerTouch
authForGoogleFromKeychainForName:kKeychainItemName
clientID:kClientID
clientSecret:kClientSecret];
if ([auth refreshToken] == nil) {
GTMOAuth2ViewControllerTouch *authController;
authController = [[GTMOAuth2ViewControllerTouch alloc]
initWithScope:scope
clientID:kClientID
clientSecret:kClientSecret
keychainItemName:kKeychainItemName
delegate:self
finishedSelector:#selector(viewController:finishedWithAuth:error:)];
[[self navigationController] pushViewController:authController animated:YES];
}else{
[auth beginTokenFetchWithDelegate:self didFinishSelector:#selector(auth:finishedRefreshWithFetcher:error:)];
}
}
and RETAIN the authentication object if signed in successfully, then use that auth object when using google plus services:
GTLServicePlus* plusService = [[[GTLServicePlus alloc] init] autorelease];
[plusService setAuthorizer:self.auth];//!!!here use our authentication object!!!
No need for GPPSignIn.
Full write up is here: Here is Another Solution
Use the (new) Google Sign In iOS SDK.
The SDK natively supports Sign In through WebView when no Google app is present to complete the Sign In process. It also supports potential dispatch to several Google apps for this purpose.
I have a button that brings up the Facebook ui to make a post, but it doesn't do anything on the device. It works fine in the simulator, but performs no action at all on the phone.
Not sure what I can do to figure out the problem -
Here is my ViewController.h
- (IBAction)postToFacebook:(id)sender;
ViewController.m
- (IBAction)postToFacebook:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[controller setInitialText:#"Posted from IOS App Test -- It works!"];
[self presentViewController:controller animated:YES completion:Nil];
}}
You code is working on simulator because isAvailableForServiceType always returns 1 in Simulator. In device you need to setup a facebook account from settings.
Or better just remove this check
[SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]
With this along with the post sheet an OS alert will appear to notify that account setup is required to post.
I want make button for share on Facebook with the social.framework. I make this:
#import <UIKit/UIKit.h>
#import <Social/Social.h>
#interface SocialSharingViewController : UIViewController
- (IBAction)postToFacebook:(id)sender;
#end
Then I add in m. File:
- (IBAction)postToFacebook:(id)sender {
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[controller setInitialText:#"First post from my iPhone app"];
[self presentViewController:controller animated:YES completion:Nil];
}
}
It's work perfect in emulator but when I test this on my iPhone 5 device it's doesn't work. When I click on the button postToFacebook nothing happens.
Pleas help me
The possible error is that your iphone 5 is not configured any fb account. [SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook] will return NO in this case
As per the documentation for the SLComposeViewController, isAvailableForServiceType "returns a Boolean value indicating whether the service is accessible and at least one account is set up... For the account to be available, the user must be logged into the social service in the device settings."
NOTE: Whenever you add a if condition, use else condition too. #codingstandard
I'm trying to implement the new social framework in iOS6, and have it working, except for 2 weird problems. If I've enabled the services I'm interested in (say... FaceBook), then it works fine. However, if the accounts are deleted from the settings panel (let's say FaceBook, to be consistent), then I get differing, and frustrating behaviors in the simulator and the device.
Here's the relevant code in my view controller:
//Method for FaceBook
- (IBAction)doFacebook:(id)sender{
//check to see if facebook account exists
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
// Create the view controller defined in the .h file
fb=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
// make the default string
NSString *FBString= [NSString
stringWithFormat:#"%#\r via #GibberishGenerator", gibText.text];
[fb setInitialText:FBString];
// show the controller
[self presentViewController:fb animated:YES completion:nil];
}
}
And here's the weird behavior when firing off the above method:
In the simulator (version 6.0 (358.4) I get the dialog informing me that I haven't set up any faceBook accounts with "Settings" and "Cancel" buttons. Hitting "Settings" just dismisses the dialog, but doesn't take me to the settings panel.
On my iPhone 4s running 6.01, hitting the button that triggers the method results in... nothing. In other words, I get no dialog informing me that I have to set up a FaceBook account.
Thanks in advance for your help.
OK... Here's the fix:
Here's my new implementation, based on user1734802's helpful comment.
//Method for FaceBook
- (IBAction)doFacebook:(id)sender{
// Create the view controller defined in the .h file
fb=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
// make the default string
NSString *FBString= [NSString
stringWithFormat:#"%#\r via #GibberishGenerator", gibText.text];
[fb setInitialText:FBString];
// show the controller
[self presentViewController:fb animated:YES completion:nil];
}
At some point I expect
[SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
to actually work correctly (triggering the automatic dialog, and taking you to settings), so I actually just commented it out in my code.
I had the same problem, i fixed it by removing the If statement:
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
Then the view will display although there is no Facebook/Twitter account configured in the settings.
And the "No Facebook/Twitter accounts" alertView showed! And I was able to hit the "Settings" button on the alert, and it directed me to the settings (Configure Facebook/Twitter account in the settings)
This is the code I used, and it works perfectly for me:
- (IBAction)bTwitter:(id)sender {
mySLComposerSheet = [[SLComposeViewController alloc] init];
mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[mySLComposerSheet setInitialText:#""];
[mySLComposerSheet addImage:[UIImage imageNamed:#""]];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
}
