iOS share button crashing when run on ipad - ios

Question

I am working on a xcode project in objective-c and i want a share button on my ios application to share things i watched a tutorial on youtube here's the link : https://www.youtube.com/watch?v=zkrOKN_OA_A
but when i run this code on iphone it works properly and when i run this code on ipad the xcode give's me this error :
int main(int argc, char * argv[]) {
#autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}}
I used this code :
- (IBAction)Share1:(id)sender {
UIImage *shareImage = [UIImage imageNamed:#"invoice_logo.png"];
NSArray *itemsToShare = #[shareImage];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil];
activityVC.excludedActivityTypes = #[];
[self presentViewController:activityVC animated:YES completion:nil];}

Answer 1

You are missing :
activityVC.excludedActivityTypes=#[UIActivityTypePostToFacebook,UIActivityTypePostToTwitter]// add your share types
look at the video you provided from 7:30 min

Answer 2

Try this:
UIImage *shareImage = [UIImage imageNamed:#"invoice_logo.png"];
NSArray *itemsToShare = #[shareImage];
UIActivityViewController *activityVC = [[UIActivityViewController alloc]
initWithActivityItems:itemsToShare applicationActivities:nil];
activityVC.popoverPresentationController.sourceView = self.view;
activityVC.popoverPresentationController.sourceRect =
CGRectMake(self.view.bounds.size.width / 2.0, self.view.bounds.size.height-50, 1.0, 1.0);
[self presentViewController:activityVC animated:YES completion:nil];
