I am trying to share the local UIImage using FBWebDialogs. But I am getting any solution which will share the local image using FBWebDialogs. Can anybody tell me , how can I share local UIImage using FBWebDialogs ?
Note: My iOS app is totally local. So I can't get the image URL.
Here is my code
-(void)shareInformationUsingFeedDialogWithParameters:(NSDictionary*)params
{
[FBWebDialogs presentFeedDialogModallyWithSession:nil
parameters:params
handler:
^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
{
if (error)
{
[self showAlertWithTitle:#"Error" andMessage:#"An error occured while sharing information using Facebook"];
}
else
{
if (result == FBWebDialogResultDialogNotCompleted)
{
[self showAlertWithTitle:#"Alert" andMessage:#"You cancelled the Facebook sharing"];
}
else
{
[self showAlertWithTitle:#"Success" andMessage:#"Facebook sharing successful"];
}
}
}];
}

I am trying to create a custom login button for IOS 9,i have been following the Facebook's tutorial for doing so but when i button is clicked,i end up getting this error
libc++abi.dylib: terminate_handler unexpectedly threw an exception
I have been following this Facebook tutorial,only difference is i am using dispatch_async due to some reasons.
https://developers.facebook.com/docs/facebook-login/ios#loginkit
dispatch_async(dispatch_get_main_queue(), ^{
NSMutableArray* Permissions = [[NSMutableArray alloc] init];
[Permissions addObject:#"email"];
[Permissions addObject:#"public_profile"];
FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logInWithReadPermissions:Permissions
handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
{
if (error)
{
NSLog(#"Process error");
}
else if (result.isCancelled)
{
NSLog(#"Cancelled");
}
else
{
NSLog(#"Logged in");
}
];
});
I have tried using Parse SDK's code too like so...
NSArray *permissionsArray = #[ #"user_about_me", #"user_relationships", #"user_birthday", #"user_location"];
[PFFacebookUtils logInInBackgroundWithReadPermissions:permissionsArray block:^(PFUser *user, NSError *error)
{
if (!user)
{
NSLog(#"Uh oh. The user cancelled the Facebook login.");
}
else if (user.isNew)
{
NSLog(#"User signed up and logged in through Facebook!");
}
else
{
NSLog(#"User logged in through Facebook!");
}
}];
But both the time,i end up getting the same error like as shown in the image below..

Am i doing something wrong in app validation process?
Please help!
Thank you!
This is weird,after playing around in Xcode,i found that it is not able to get my appID and other settings from my plist even though it's there.After i programmatically set my app id using
[FBSDKSettings setAppID:#"appid"];
[FBSDKSettings setDisplayName:#"displayname"];
I was to able get rid of that error,but i am stuck at URLSchemes...i will recreate the project and try again!
Thank you!
It's working now and,i am able to get a login page,but after i get past the app login screen,i am getting a blank white screen with only a done button at th top right corner,when i click it,i get the log message that the user cancelled login.
Sometimes when I launch the Facebook share dialog, the OS switches to the Facebook app, but the share dialog doesn't load. Then if you try again, it usually works. Why doesn't it work the first time?
NSURL* url = [NSURL URLWithString:#"some URL"];
FBShareDialogParams* params = [[FBShareDialogParams alloc] init];
params.link = url;
if ([FBDialogs canPresentShareDialogWithParams:params]) {
[FBDialogs presentShareDialogWithLink:url
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error posting to FB: %#", error.description);
//do something
} else {
//do something else
}
}];
// }
}
This class is no longer available in the most recent version of the SDK.
You should use FBSDKShareDialog instead of this.The latest version is v4.11.0.
Thanks.
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[action setObject:#"https://example.com/book/Snow-Crash.html"
forKey:#"book"];
[FBDialogs presentShareDialogWithOpenGraphAction:action
actionType:#"books.reads"
previewPropertyName:#"book"
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error: %#", error.description);
} else {
NSLog(#"Success!");
}
}];
I use the above codes to present a facebook shareDialog in my application ,but it does not work in both ios 5.1 and 6.1.I want to know the reason.
From my understanding as of now (I might be wrong), this code invokes the facebook native iOS app. If you are testing this on the simulator and don't have the iOS app installed, this will not work. It is unlikely you will be able to test this on the simulator. Try it on a real device that has the facebook iOS app installed.
Do you have the latest Facebook app installed?
Also, you're trying to post an open graph action using facebook's example action, which I'm not sure even exists. If you have registered custom open graph actions with you app, I suggest you modify your code to invoke it instead. If you don't have custom actions, I suggest starting with posting simple urls to see if it works for you.
Use:
NSURL* url = [NSURL URLWithString:#"https://developers.facebook.com/"];
[FBDialogs presentShareDialogWithLink:url
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"Error: %#", error.description);
} else {
NSLog(#"Success!");
}
}];
And lastly I suggest you read this: https://developers.facebook.com/ios/share-dialog/
I am implementing the Facebook SDK into my app . I am using FBLoginView to login with Facebook. I have a UIButton, which I'm using to share on a user's Facebook wall. Now I don't want to login using FBLoginView , i want to check if there is a Facebook app, and if the user has logged in.
- (IBAction)pickFriendsList:(UIButton *)sender
{
FBFriendPickerViewController *friendPickerController = [[FBFriendPickerViewController alloc] init];
friendPickerController.title = #"Pick Friends";
[friendPickerController loadData];
// Use the modal wrapper method to display the picker.
[friendPickerController presentModallyFromViewController:self animated:YES handler:
^(FBViewController *sender, BOOL donePressed) {
if (!donePressed) {
return;
}
NSString* fid;
NSString* fbUserName;
for (id<FBGraphUser> user in friendPickerController.selection)
{
NSLog(#"\nuser=%#\n", user);
fid = user.id;
fbUserName = user.name;
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:#"test", #"message", #"http://webecoist.momtastic.com/wp-content/uploads/2009/01/nature-wonders.jpg", #"picture", #"Sample App", #"name",fid,#"tags",fid,#"to",#"106377336067638",#"place", nil];
[FBRequestConnection startWithGraphPath:[NSString stringWithFormat:#"%#/feed",fid] parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection,id result,NSError *error)
{
[FBWebDialogs presentFeedDialogModallyWithSession:nil parameters:params handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
{
if (error)
{
// Error launching the dialog or publishing a story.
NSLog(#"Error publishing story.");
}
else
{
if (result == FBWebDialogResultDialogNotCompleted) {
// User clicked the "x" icon
NSLog(#"User canceled story publishing.");
}
else
{
// Handle the publish feed callback
//Tell the user that it worked.
}
}
}];
}];
}
}];
}
I am assuming that you are using iOS 6 sdk. In which case, Use below code (workable for device) :
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
//user is already logged in using iOS integrated FB a/c
}
else
{
//user is not logged in
}
Note: FBSession can't check this criteria. So session check with FBSession has a different meaning from above code.
Regards,
Check for the URL Scheme fb://
[[UIApplication sharedApplication] canOpenURL:#"fb://"] returns YES if Facebook App is installed. This post lists, de available URL schemes for Facebook: https://stackoverflow.com/a/5707825/1511668
Maybe fb://online is what you are looking for.
I have an App which stores images to Custom Library in Photo Album in iphone.
I called the following Function of ALAssetLibrary
-(void)saveImage:(UIImage*)image toAlbum:(NSString*)albumName withCompletionBlock:(SaveImageCompletion)completionBlock
{
//write the image data to the assets library (camera roll)
[self writeImageToSavedPhotosAlbum:image.CGImage orientation:(ALAssetOrientation)image.imageOrientation
completionBlock:^(NSURL* assetURL, NSError* error) {
//error handling
if (error!=nil) {
completionBlock(error);
return;
}
//add the asset to the custom photo album
[self addAssetURL: assetURL
toAlbum:albumName
withCompletionBlock:completionBlock];
}];
}
in my SaveImage IBAction
-(IBAction)saveToLib:(id)sender
{
UIImage *savedImage = imgPicture.image;
NSLog(#"Saved Image%#",savedImage);
[self.library saveImage:savedImage toAlbum:#"Touch Code" withCompletionBlock:^(NSError *error) {
if (error!=nil) {
NSLog(#"Big error: %#", [error description]);
}
}];
}
but my application keep getting Crashed
Help me out
Thanks in Advance
It seems that you are not calling the [self.library saveImage:savedImage toAlbum:#....] correctly. If you are following this web site, add #import "ALAssetsLibrary+CustomPhotoAlbum.h" in your view controller.
Not sure if it is the problem. Sorry if this workaround is the wrong approach.
Problem is the file from the website he downloaded.
I had the same issue and rewriting the code myself solved this.
Maybe encoding or something like this...
