applicationActivities:nil];
activityViewController.excludedActivityTypes = excludeActivities;
[self presentViewController:activityViewController

itemForActivityType:(NSString *)activityType
{
if ([activityType isEqualToString:UIActivityTypePostToFacebook]) {

For that just create one class for that like this.
SharingActivityProvider.h
#import <Foundation/Foundation.h>
#interface SharingActivityProvider : UIActivityItemProvider
#end
**SharingActivityProvider.m**
#import "SharingActivityProvider.h"
#implementation SharingActivityProvider {
}
- (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType {
// Create the default sharing string
NSString *shareString = #"";
// customize the sharing string for facebook, twitter, weibo, and google+
if ([activityType isEqualToString:UIActivityTypePostToFacebook]) {
shareString = [NSString stringWithFormat:#"Attention Facebook:%#", shareString];
} else if ([activityType isEqualToString:UIActivityTypePostToTwitter]) {
shareString = [NSString stringWithFormat:#"Attention Twitter:%#", shareString];
} else if ([activityType isEqualToString:UIActivityTypePostToWeibo]) {
shareString = [NSString stringWithFormat:#"Attention Weibo:%#", shareString];
}
return shareString;
}
- (id)activityViewControllerPlaceholderItem:(UIActivityViewController *)activityViewController {
return #"";
}
#end
Then after just use below code, suppose button action.
-(IBAction)shareAppTapped:(id)sender{
SharingActivityProvider *sharingActivityProvider = [[SharingActivityProvider alloc] init];
NSArray *activityProviders = #[sharingActivityProvider,#"what ever text"];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityProviders applicationActivities:nil];
// tell the activity view controller which activities should NOT appear
activityViewController.excludedActivityTypes = #[UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll];
activityViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:activityViewController animated:YES completion:nil];
// [self.btnShareApp setBackgroundColor:OnebackgroundColorTable];
}

One mistake here is exclude activities also have facebook and twitter. Hence it will not show by any means.
Note excludedActivityTypes should be which you does not need in controller.
For example it should be:
NSArray *excludeActivities = #[UIActivityTypePostToWeibo,
UIActivityTypeMessage,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo,
UIActivityTypePostToTencentWeibo];
