Issue posting file url using UIActivityViewController - facebook

Question

I am trying to share my app document (file url ) using UIActivityViewController. When activityviewcontroller pop up (testing on iPad device), I get only iMessage and Mail options. I DO NOT GET OTHER OPTIONS like Facebook, Twitter, Copy, Print, etc. Why? Please help me. I need Facebook, twitter options also. File type which I am sharing using NSURL is .txt
Note: I am already signed in to my Facebook, twitter account in iOS settings.
Source code which I am using:
NSURL *url = [NSURL fileURLWithPath:self.path];
NSArray *objectsToShare = #[url];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
[APP_VIEW_CONTROLLER presentViewController:activityViewController animated:YES completion:nil];
}
else
{
if (![self.activityPopover isPopoverVisible]) {
self.activityPopover = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
[self.activityPopover presentPopoverFromRect:pathViewController.pathViewWrapper.pathView.bounds inView:pathViewController.pathViewWrapper.pathView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
else
{
//Dismiss if the button is tapped while pop over is visible
[self.activityPopover dismissPopoverAnimated:YES];
}
}

Answer 1

It is indeed mysterious what shows up in the UIActivityViewController. Regarding Facebook and Twitter 1) it likely needs to be an http or https URL (not a file URL), 2) make sure those services are configured on the simulator or iOS device you're using.

Answer 2

For posting to Facebook. The file can be a file stored on the device locally. However, it needs to be converted to MP4. By default, videos taken by device camera are .MOV files. Once you convert to .MP4 if you provide the local file location, UIActivityController will share to Facebook.
I got FB to work, I'm working on Twitter now. I will edit my answer and provide details when I'm done.
Here is some code:
UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:activities];
activityController.excludedActivityTypes = #[ UIActivityTypeMail,
UIActivityTypeAssignToContact,
UIActivityTypePrint,
UIActivityTypeCopyToPasteboard,
UIActivityTypeAddToReadingList,
UIActivityTypeSaveToCameraRoll];
NSMutableArray *items = [[[Engine sharedEngine].thingsManager getSharingMessageForThingWithId:self.thingId
categoryName:self.category.name
brandName:self.brand.name
andText:message
isVideo:([self.videoURL.absoluteString length] > 0 ? YES : NO)] mutableCopy];
if ([self.videoURL.absoluteString length] > 0) {
//Get the .mp4 converted video url
if (self.awsManager == nil) {
self.awsManager = [[AWSManager alloc] init];
}
NSURL *mp4Url = [self.awsManager convertVideoToMP4:self.videoURL];
//[items addObject:self.videoAmazonPath];
[items addObject:mp4Url];
} else {
[items addObject:self.image];
}
Hope this helps.
