I use UIActivityViewController to share multiple images but when I choose a Gmail in the list, it opens it, then I see my attached files and then Gmail extension crashes. Next time it even doesn't open when I choose it.
But everything works fine with Mail app or other apps in the list in UIActivityViewController.
NSArray *scans = self.document.scans;
NSMutableArray *imagesData = [NSMutableArray arrayWithCapacity:[scans count]];
for (DScan *scan in scans) {
UIImage *image = [scan fullImageWithError:nil];
[imagesData addObject:UIImageJPEGRepresentation(image, 0.6)];
}
UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:imagesData applicationActivities:nil];
[self presentViewController:controller animated:YES completion:nil];
Please help my understand what is wrong in the code.
Thank you in advance!

I can't share anything via linkedin using UIActivityViewController. While I tap share via linkedin, it opens the sharing pop up and dismisses immediately after opened it. All other sharing are working fine. Could you please tell me a solution? Thanks.
Note: my project is in ios9 and xcode version is 7
and my error log shows : plugin com.linkedin.LinkedIn.ShareExtension interrupted
The iOS 8 extensions cannot be presented in a custom share screen. You absolutely have to use UIActivityViewController in order for the share/action extensions to appear.
Have you written the code like this
DataItemProvider *dataToShare = [[DataItemProvider alloc] initWithPlaceholderItem:FileTypeToShare];
LinkedInActivityType *linkedinActivity = [[LinkedInActivityType alloc] init];
NSArray *activityTypes = #[linkedinActivity];
NSArray *activityItems = #[dataToShare];
UIActivityViewController *activityController = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:activityTypes];
[activityController setCompletionHandler:^(NSString *activityType, BOOL completed) {
//Put in your completion handle code here.
}];
[self presentViewController:activityController animated:YES completion:nil];
My iOS is 8.1.2 and I am using the UIActivityViewController for social sharing.
I click on a button and allow the UIActivityViewController to present
- (IBAction)UIActivityTypeButtonClick:(id)sender {
NSString* text=#"I am sharing this text";
NSArray* sharedArray=#[text];
UIActivityViewController * activityVC=[[UIActivityViewController alloc]initWithActivityItems:sharedArray applicationActivities:nil];
activityVC.excludedActivityTypes=#[];
[self presentViewController:activityVC animated:YES completion:nil];
}
I am getting this
I am getting Message, Twitter, Mail, WhatsApp and a More button.
On clicking More I get this.
Where is FACEBOOK. I have the facebook app in my iPhone and it is setup with my ID too in settings. But facebook never shows up here. Twitter does. Is this a bug or what? Please suggest
Thanks
I first saw this when Facebook updated their app on April 24th. Plain text sharing to Facebook isn't working as long as the Facebook app is installed. After you delete it, it's available again.
If you try to share a URL or an image together with the plain text, you will see Facebook as an option but the text field will be blank. The image or URL will attach without a problem.
I posted a sample project that reproduces this problem on github:
https://github.com/djr/UIActivityViewController-Facebook
This is not an answer, but it's pretty clear that the problem is caused by the Facebook app.
EDIT:
It's not ideal, but I created a workaround. Don't forget that you will need to attach an image or a URL for this to work.
Detect if the user has the Facebook app installed. If they do, then give them some type of informational message.
BOOL facebookIsInstalled = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:#"fb://"]];
BOOL isUserLoggedInWithFacebook = [SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook];
if(isUserLoggedInWithFacebook && facebookIsInstalled)
{
// Explain that they have to copy and paste in order to share on Facebook
}
Create a subclass of UIActivityItemProvider and override
- (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType
{
NSString *stringToShare = #"string to share";
if([activityType isEqualToString:UIActivityTypePostToFacebook] ||
[activityType isEqualToString:#"com.facebook.Facebook.ShareExtension"] ||
[activityType.lowercaseString rangeOfString:#"facebook"].length)
// Because who knows when they are going to change the activityType string?
{
// Automatically copy the text for them
[[UIPasteboard generalPasteboard] setString:stringToShare];
}
return stringToShare;
}
Tell the user that they have to paste into the Facebook text field in order to share.
Blame it on Facebook.
I confirm what djr reported - if you have the FB app text is no longer shared. I deleted the FB app and now sharing both text and image works.
Facebook would like you to use their SDK. They have blocked the ability to set initial text. (Not sure how.) Check out my answer in a similar post:
UIActivityViewController for Facebook not Showing Default Text
The desired solution (from Facebook) is to use their SDK.
NSString* text=#"I am sharing this text";
NSURL *myWebsite = [NSURL URLWithString:#"http://www.website.com/"];
// UIImage * myImage =[UIImage imageNamed:#"myImage.png"];
NSArray* sharedArray=#[text,myWebsite];
UIActivityViewController * activityVC=[[UIActivityViewController alloc]initWithActivityItems:sharedArray applicationActivities:nil];
NSArray *excludedActivities = #[];
activityVC.excludedActivityTypes=excludedActivities;
[self presentViewController:activityVC animated:YES completion:nil];
To show facebook sharing button you must add a image to the array of activity items... this may be a bug on apple side but i've not seen any open radar about this issue.
Also note on iOS 8.3 text can't be added to facebook for some reason. when adding text you only be presented to a blank textfield.
UIImage *image = [UIImage imageNamed:#"__some_image__file"];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:#[image]
applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];
I'm using a UIActivityViewController with just some of the Apple built-in services. As a test, I specify no excludedActivityTypes (the docs say this is nil by default) and no completion handler (I just want the services to do their thing).
I'm building using Xcode/SDK Version 5.1.1 (5B1008)
// this is the handler that catches the Action button tap
// self.noteArea.text is the UITextView.text string to use by the services.
- (IBAction)actionTapped:(UIBarButtonItem *)sender
{
NSString *s = [NSString stringWithString:self.noteArea.text];
NSArray *a = [NSArray arrayWithObject:s];
UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:a applicationActivities:nil];
[self.navigationController presentViewController:activityController animated:YES completion:NULL];
}
On both the simulator and a real iPhone the activity popup shows only Mail and Copy -- nothing else. Why just those two? Mail and Copy work fine, so everything that does show seems to work properly. How do I get the other functions to display?
I am trying to share a text (or an URL) and an image with AirDrop and it seems it sends only the image. It works fine with other sharing activities (Facebook, Twitter, Mail, Message etc.). Is it possible to share two items with AirDrop?
Here is how I use the UIActivityViewController:
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:#[self.activityItem, self.attachedImage] applicationActivities:nil];
self.attachedImage is an UIImage and self.activityItem is a subclass of UIActivityItemProvider which returns different text for different activity types in delegate method
- (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType
Does anyone have an idea? Thanks!
EDIT:
I also tried without subclassing UIActivityItemProvider and passed directly some text. Didn't work.
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:#[#"some text", self.attachedImage] applicationActivities:nil];
As a note, it works if I want to share multiple texts OR multiple images (UIImage):
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:#[#"text 1", #"text 2"] applicationActivities:nil];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:#[attachedImage1, attachedImage2] applicationActivities:nil];
Try this code
NSString *text= #"text to share";
CustomActivityItemProvider *textToShare = [[CustomActivityItemProvider alloc]
initWithStandardText:text];
NSArray *activityItems = #[textToShare,self.attachedImage];
Use activityItems array in activity view controller.
Posted the same question on Apple Dev Forums: https://devforums.apple.com/message/937697#937697
Got this answer:
Currently not possible. AirDrop only lets you send sets of single
items. If you are trying to send it to an instance of your own app on
the other side, you could instead create a fileformat (a
bundle/package would probably be suitable here) and embed all the
different types with the file. Then on the receiving side you can
extract the different types out of the file.
I have implemented UIActivityViewController within my app and can successfully share both strings and images. However, I notice that when you share an image within the iOS Photos app, there are some services that do not appear in my app. Namely Print, Use as Wallpaper, and Assign To Contact, and Photo Stream. My app is able to use Mail, Message, Facebook, Twitter, and Copy just fine.
I am thinking that either:
1.) These extra services have been implemented as custom services within the Photos app using UIActivityItemProvider, UIActivityItemSource, etc..
2.) The data that I am providing is not in the correct format to be used with these services.
I have read through the documentation a few times, but don't seem to see anything about it.
Edit: Showing code as requested:
#define SM_SHARE_IMAGE_AND_STRING 1
-(void)actionToolbarViewControllerUserTappedShareButton:(SMActionToolbarViewController*)sender{
// Reposition anchor view for UIPopoverController to point at
[self repositionAnchorViewToButtonFrame:self.actionToolbarViewController.shareButtonFrame];
// Asynch download of image
[SMUtility downloadAsset:self.selectedAsset completion:^(UIImage *image) {
// Create image source
SMActivitySource *activityImageSource = [[SMActivitySource alloc]initWithImage:image];
#if defined(SM_SHARE_IMAGE_AND_STRING)
// Create string source
NSString *assetsString = [SMUtility assetsString:[NSArray arrayWithObject:self.selectedAsset]];
SMActivitySource *activityStringSource = [[SMActivitySource alloc]initWithString:assetsString];
// Present UIActiviyViewController within an UIPopoverController
NSArray *items = [#[activityImageSource, activityStringSource]mutableCopy];
#else
NSArray *items = [#[activityImageSource]mutableCopy];
#endif
UIActivityViewController *activityViewController = [[UIActivityViewController alloc]initWithActivityItems:items applicationActivities:nil];
[activityViewController setCompletionHandler:^(NSString *activityType, BOOL completed){
[SMMixPanel eventSharePhotoMethod:#"Share"];
}];
self.buttonPopoverController = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
[self.buttonPopoverController presentPopoverFromRect:self.anchorView.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}];
}
The Print, and Assign To Contact activities are standard activities shown by the UIActivityViewController as long as you provide the proper data.
You must provide a UIImage for the Assign To Contact activity. See the docs for UIActivityTypeAssignToContact. See the docs for UIActivityTypePrint for details on what it accepts.
The "Use As Wallpaper" seems to be a custom activity shown only in the Photos app.
