UIActivityViewController to post different image and text for Twitter and Facebook - ios

Question

In my project,I am using UIActivityViewController to do Facebook,Twitter and email sharing.I want to share separate text and images for facebook,Email and twitter.How can i do that?
-(id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType
{
if ( [activityType isEqualToString:UIActivityTypePostToTwitter] )
return _shareText1;
if ( [activityType isEqualToString:UIActivityTypePostToFacebook] )
return _shareText2;
if ( [activityType isEqualToString:UIActivityTypeMail] )
return _shareText3;
return nil;
}
I used the above code in the subclass of UIActivityItemProvider,and passed the text to be shared from my UIViewcontroller.How to return an image with the text?Is it by returning a NSDictionary?If so,What are the keys?Please Help.

The best way you can create the UIActivity Subclass and use in UIActivityViewController..
-(void)sharePressed:(id)sender
{
GooglePlus *gPlus = [[GooglePlus alloc]init];
FacebookShare *fb =[[FacebookShare alloc]init];
NSString *textToShare = #"Text u want to share";
NSURL *myWebsite = [NSURL URLWithString:#"http://www.mywebsite.com/"];
UIImage *image =[UIImage imageNamed:#"apple.png"];
}
NSArray *objectsToShare = #[textToShare, myWebsite,image];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:
[NSArray arrayWithObjects:gPlus,fb,nil]];
activityVC.completionHandler = ^(NSString *activityType, BOOL completed)
{
// NSLog(#" activityType: %#", activityType);
// NSLog(#" completed: %i", completed);
};
NSArray *excludedActivities = #[UIActivityTypePostToTwitter,
UIActivityTypePostToWeibo,
UIActivityTypeMessage,
UIActivityTypePrint, UIActivityTypeCopyToPasteboard,
UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList, UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo, UIActivityTypePostToTencentWeibo,UIActivityTypePostToFacebook];
activityVC.excludedActivityTypes = excludedActivities;
[self presentViewController:activityVC animated:YES completion:nil];
// Create the subclass the UIActivity Class using delegates
-(NSString *)activityType
{
return #"GooglePlus";
//CustomActivity
}
-(NSString *)activityTitle
{
return #"GooglePlus ";
// use your custom ActivityTitle
}
-(UIImage *)_activityImage
{
// Note: These images need to have a transparent background and I recommend these sizes:
// iPadShare#2x should be 126 px, iPadShare should be 53 px, iPhoneShare#2x should be 100
// px, and iPhoneShare should be 50 px. I found these sizes to work for what I was making.
return [UIImage imageNamed:#"G+-60x60.png"];
}
-(BOOL)canPerformWithActivityItems:(NSArray *)activityItems
{
NSLog(#"%s", __FUNCTION__);
return YES;
}
-(void)prepareWithActivityItems:(NSArray *)activityItems
{
NSLog(#"%s",__FUNCTION__);
}
-(UIViewController *)activityViewCtroller
{
NSLog(#"%s",__FUNCTION__);
return nil;
}
-(void)performActivity
{
// share what stuff u want to share
}
