I am facing app extension close issues , please tell me if anyone know what wrong am doing.I am using action extension after preform some action inside extension i need to return response back.
Sample Code
// With Success Case
- (void) completeActionWithItems: (NSString *) response {
NSExtensionItem *extensionItem = [[NSExtensionItem alloc] init];
extensionItem.attachments = #[[[NSItemProvider alloc] response typeIdentifier: (NSString *)kUTTypePlainText]];
[self.extensionContext completeRequestReturningItems: #[extensionItem] completionHandler: nil];
}

[self.extensionContext cancelRequestWithError: error];
}
With Success Case working fine but some time is not closing,
With Error Case not working above code.
Please let me know what went wrong.Thanks

When you create an action extension, this is the default method which will close the Action Extension View Controller:
- (IBAction)done {
// Return any edited content to the host app.
// This template doesn't do anything, so we just echo the passed in items.
[self.extensionContext completeRequestReturningItems:self.extensionContext.inputItems completionHandler:nil];
}
Since this method is already provided, you should just try calling it from your success method.
// With Success Case
- (void) completeActionWithItems: (NSString *) response {
NSExtensionItem *extensionItem = [[NSExtensionItem alloc] init];
extensionItem.attachments = #[[[NSItemProvider alloc] response typeIdentifier: (NSString *)kUTTypePlainText]];
[self.extensionContext completeRequestReturningItems: #[extensionItem] completionHandler: nil];
// Call to "done" method
[self done];
}
