Different data for sharing providers in UIActivityViewController
I think this is what you're looking for: Custom UIActivityViewController icons and text.
You should be able to provide different data for each activity type.
Hope this helps somebody. It's pretty straightforward if you subclass UIActivityItemProvider
:
@interface MyActivityItemProvider : UIActivityItemProvider
@end
@implementation MyActivityItemProvider
- (id)item
{
// Return nil, if you don't want this provider to apply
// to a particular activity type (say, if you provide
// print data as a separate item for UIActivityViewController).
if ([self.activityType isEqualToString:UIActivityTypePrint])
return nil;
// The data you passed while initialising your provider
// is in placeholderItem now.
if ([self.activityType isEqualToString:UIActivityTypeMail] ||
[self.activityType isEqualToString:UIActivityTypeCopyToPasteboard])
{
return self.placeholderItem;
}
// Return something else for other activities. Obviously,
// you can as well reuse the data in placeholderItem here.
return @"Something else";
}
@end
Then pass its instance with an array of activity items to UIActivityViewController:
MyActivityItemProvider *activityItem =
[[MyActivityItemProvider alloc] initWithPlaceholderItem:@"Your data"];
NSArray *sharingItems = [NSArray arrayWithObjects:
activityItem, _myUITextView.viewPrintFormatter, nil];
UIActivityViewController *activityController =
[[UIActivityViewController alloc]
initWithActivityItems:sharingItems applicationActivities:nil];
This can be easily done by using the optional activityType
property from the UIActivityItemProvider
object. That property returns a UIActivityType
, so you can do something like:
class PhotoActivityItemProvider: UIActivityItemProvider {
...
override var item: Any {
guard let activityType = self.activityType else {
return photoURL.absoluteString
}
if activityType == .mail || activityType == .message {
return "The photo link is \(photoURL.absoluteString)."
}
...
}
