How to display the default iOS 6 share action sheet with available share options?
Add this to use the UIActivityViewController
.
-(IBAction)shareButtonPressed:(id)sender {
NSLog(@"shareButton pressed");
NSString *texttoshare = _txt; //this is your text string to share
UIImage *imagetoshare = _img; //this is your image to share
NSArray *activityItems = @[texttoshare, imagetoshare];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePrint];
[self presentViewController:activityVC animated:TRUE completion:nil];
}
The UIActivityViewController stated in the other answer makes this trivial. All you have to do is specify the text/image/URL that you want to share and present the activity view controller modally and iOS will automatically display all applicable sharing services. Examples:
Objective-C
- (void)shareText:(NSString *)text andImage:(UIImage *)image andUrl:(URL *)url
{
NSMutableArray *sharingItems = [NSMutableArray new];
if (text) {
[sharingItems addObject:text];
}
if (image) {
[sharingItems addObject:image];
}
if (url) {
[sharingItems addObject:url];
}
UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil];
[self presentViewController:activityController animated:YES completion:nil];
}
Swift
func share(sharingText: String?, sharingImage: UIImage?, sharingURL: URL?) {
let sharingItems:[AnyObject?] = [
sharingText as AnyObject,
sharingImage as AnyObject,
sharingURL as AnyObject
]
let activityViewController = UIActivityViewController(activityItems: sharingItems.compactMap({$0}), applicationActivities: nil)
if UIDevice.current.userInterfaceIdiom == .pad {
activityViewController.popoverPresentationController?.sourceView = view
}
present(activityViewController, animated: true, completion: nil)
}
