I add an activityViewController to my app like below, passing in an image
UIActivityViewController *avc = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:img,nil] applicationActivities:[NSArray arrayWithObjects:nil]];
[self presentModalViewController:avc animated:YES];
[avc release];
On the simulator (twitter, facebook and weibo accounts all not configured):
options mail, twitter, facebook, weibo, assign to contact, save to camera roll, print, and copy appear by default.
but on device:
in my app: twitter, facebook and weibo only show if the accounts are configured.
in safari: twitter, facebook and weibo options are available irregardless of whether the accounts are configured.
I am expecting the same behaviour in my app as safari. am I missing a particular step?
Okay I have figured the problem.
The options shown in the UIActivityViewController totally depends on the type of items that are to be shared. For example, if there is a video, it will not show Facebook or twitter option. But if it's an image and title, it definitely will show the relevant options.
The following will show up apps like mail, twitter, Facebook, assignToContact, save to camera roll, print, copy, etc
// Create the content
NSString *message = #"The Upcoming App Scribble Talk";
UIImage *imageToShare = [UIImage imageNamed:#"createbtn.png"];
NSArray *objectsToShare = [NSArray arrayWithObjects:message, image, nil];
However, the following shall bring up only camera roll, mail or copy.
NSString *message = #"The Upcoming App Scribble Talk";
NSString *videoToShare = #"myFirsScribble.mov";
NSURL *videoPath = [NSURL fileURLWithPath:videoToShare];
NSArray *objectsToShare = [NSArray arrayWithObjects:message, videoPath, nil];
I think you want to show some certain service only in your UIActivityViewController. You may one property called excludedActivityTypes to be defined as below to avoid some default activity.
UIActivityViewController *yourvc = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:img,nil] applicationActivities:[NSArray arrayWithObjects:nil]];
yourvc.excludedActivityTypes = #[UIActivityTypePostToWeibo,UIActivityTypePrint,UIActivityTypeMail,UIActivityTypeCopyToPasteboard];//Try this code in simulator.. you can only see FB & Twitter.
[self presentModalViewController:yourvc animated:YES];
[avc release];
likewise you can excluded from default UIActivityViewController..

I want to share video in my application to wechat via "UIActivityViewController"
But I got "transfer fail" message on WeChat's transfer dialog very often (alsmost 90%)
But I try to save same video to my iPhone Photos,
then share to wechat, But I never fail on it.
Is there anything I have to do before share?
My code:
NSMutableArray *shareFile = [[NSMutableArray alloc] init];
NSURL *shared = [NSURL fileURLWithPath:file.localFilePath];
if ([[NSFileManager defaultManager] fileExistsAtPath:file.localFilePath]) {
[shareFile addObject: shared];
}
UIActivityViewController *_shareVC = [[UIActivityViewController alloc] initWithActivityItems:[shareFile copy] applicationActivities:nil];
[_shareVC setCompletionWithItemsHandler:nil];
In iOS9.3,10.2,10.3 equipment on the same problem, share the video to WeChat friends, suggesting that "发布不成功", 100%, but in iOS8.4 can share success, use of UIActivityViewController.
Is there a way to share text on facebook messenger without SDK?
I found the following method.
-(void)shareAction:(NSString *)str param:(NSString *)strTitle
{
NSString *title = strTitle;
NSURL *url = [[NSURL alloc]initWithString:str];
NSArray *postItems = #[title, url];
UIActivityViewController *activityVC = [[UIActivityViewController alloc]
initWithActivityItems:postItems
applicationActivities:nil];
activityVC.excludedActivityTypes = #[];
[self presentViewController:activityVC animated:YES completion:nil];
}
However, not just how to select Facebook Messenger among the various apps,
I want to send it directly to Facebook Messenger.
Is there a way without the SDK?
You can use UIActivityViewController to share the app using Facebook Messenger. Please check following sample URL which will display the App list which have implemented share extension.

I have some trouble with create native share dialog.
My goal is share link of my product by native view controller, but I can't do it. I'm trying test code:
NSURL *google = [NSURL URLWithString:#"http://google.com"];
NSArray *activityItems = #[google];
UIActivity *activity = [UIActivity new];
UIActivityViewController *activityViewControntroller = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:#[activity]];
activityViewControntroller.excludedActivityTypes = #[];
[self presentViewController:activityViewControntroller animated:true completion:nil];
And I get no FB and twitter icons. In the other hand, I can see it in safari both icons and when I'm touching it I see "You need configure your account before post".
So, I want the same behavior: icons for all most-popular social networks such as VK, FB, twitter; messengers like whatsapp, viber and telegram. If some of them is not installed I want dialog "You have to log in before" and redirect to safari (e.g. for FB) to log in or open appstore (e.g. for telegram or viber) to install; otherwise I want post message with my link.
I see it like this: exclude all types from activity vc, than forcibly add all icons I need and check each of them on click manually. But in apple docs I've read that "you have to use native behavior for native items instead of create custom". So, will it be correct? Or there are other ways to solve this?
Try this
-(void)clickShare:(UIButton *)sender{
NSArray * activityItems = #[[NSString stringWithFormat:#"Some initial text."], [NSURL URLWithString:#"http://www.google.com"]];
NSArray * applicationActivities = nil;
NSArray * excludeActivities = #[];
UIActivityViewController * activityController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:applicationActivities];
activityController.excludedActivityTypes = excludeActivities;
[self presentViewController:activityController animated:YES completion:nil];
}
this code working in my project.
For some reason when I use ActivityViewController from my app I don't get the option to share using Airdrop. If i use it from Chrome, I do get the option:
This is the code that I'm using:
NSMutableArray * items = [NSMutableArray new];
[items addObject:#"text for share"];
[items addObject:[UIImage imageNamed:#"image"]];
NSArray *activityItems = [NSArray arrayWithArray:items];
UIActivityViewController *activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:activityItems
applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:^{
.....
}];
But I only get this:
How do I add the Airdrop option?
In order to be able to send something over AirDrop the item will need to be a URL. I couldn't find the official documentation, but in this Apple AirDrop Example it states:
URLs can be used as a simple way to transfer information between devices. Apps can easily parse a received URL to determine what action to take. After an app registers a URL scheme (including custom schemes), the system will know to launch that app when a URL of that type is received.
I'm sharing an image and its description text using UIActivityType. I need to share the URL of the image if I choose SMS sharing option. How can I do that? Currently I'm sharing the image and data to Facebook and Twitter. How to send the URL in case that SMS option is selected?
You can share the image using SMS option in the same way that you are doing it with Facebook and Twitter.
The activityType for SMS is UIActivityTypeMessage. It is the built-in activityType.
So the only thing you need to do is provide image and image description as activityItems while creating your UIActivityController.
The code snippet is given below:
NSString *imageDescription = #"Image Description Goes Here";
UIImage *image = [UIImage imageNamed:#"Image_Name"];
NSArray *items = [NSArray arrayWithObjects: imageDescription,image,nil];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:nil];
[self presentViewController:activityVC animated:YES completion:nil];
