How can I share a file with iOS? - ios

Question

So I have my app create a file, in this case it's actually an animated .gif. This animated .gif is saved on the device and is all ready to go - what I want to do now is share this file when the user clicks the "Share" button.
Simply put, how can I achieve this?
Is there a way to just tell iOS to open up the share window and that I'm sharing an image? Right now I can't find a way to do that, so instead I'm creating a new UIImage with a path to this animated .gif on the device, but this ends up converting my animated file into a static image.
Again - I already have the animated .gif file created and saved on the user's device.
Any help appreciated.
Edit: To clarify, I'm used to Android, I just call up an intent to share a file and up pops a list of Gmail, Facebook, Twitter, etc, etc... I basically want the equivalent of that, if possible.

Answer 1

You may want to take a look at the UIActivityViewController document. This will open a sheet with all the ways available to share on the device. See here https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIActivityViewController_Class/index.html#//apple_ref/doc/uid/TP40011976-CH1-SW2 . You may want to initialize the ActivityViewController with images or UIActivityItemSource

Facebook and twitter not support UIActivityViewController, still in this used only limited application. Now this code very usedfully.
-(void)uploadImageToTwitter {
ACAccountStore *account = [[ACAccountStore alloc] init];
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:
ACAccountTypeIdentifierTwitter];
[account requestAccessToAccountsWithType:accountType options:nil
completion:^(BOOL granted, NSError *error)
{
if (granted == YES)
{
NSArray *arrayOfAccounts = [account
accountsWithAccountType:accountType];
if ([arrayOfAccounts count] > 0)
{
ACAccount *twitterAccount =
[arrayOfAccounts lastObject];
//
// NSURL *furl = [NSURL fileURLWithPath:NSTemporaryDirectory()];
// NSURL *fileURL = [furl URLByAppendingPathComponent:#"animation.gif"];
NSData *imageData = [NSData dataWithContentsOfURL:_GIFURL];
NSURL *requestURL = [NSURL URLWithString:#"https://upload.twitter.com/1.1/media/upload.json"];
SLRequest *postRequest = [SLRequest
requestForServiceType:SLServiceTypeTwitter
requestMethod:SLRequestMethodPOST
URL:requestURL parameters:nil];
postRequest.account = twitterAccount;
[postRequest addMultipartData:imageData
withName:#"media"
type:#"image/gif"
filename:#"test.gif"];
[postRequest
performRequestWithHandler:^(NSData *responseData,
NSHTTPURLResponse *urlResponse, NSError *error)
{
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:nil];
NSString *mediaID = [json objectForKey:#"media_id_string"];
if (mediaID!=nil) {
NSURL *requestURL2 = [NSURL URLWithString:#"https://api.twitter.com/1.1/statuses/update.json"];
NSDictionary *message2 = #{#"status": #"Here is the image",
#"media_ids": mediaID };
SLRequest *postRequest2 = [SLRequest
requestForServiceType:SLServiceTypeTwitter
requestMethod:SLRequestMethodPOST
URL:requestURL2 parameters:message2];
postRequest2.account = twitterAccount;
[postRequest2
performRequestWithHandler:^(NSData *responseData,
NSHTTPURLResponse *urlResponse, NSError *error)
{
// DONE!!!
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"Notification" message:#"Upload Twitter Account" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}];
}
}];
}
}
}];
}
