My app uses custom notifications with custom images. Why do these images get mixed up with those from other apps, causing my notifications to display images from other apps? `INImage *avatarImage = [INImage imageWithImageData:imageData];
NSPersonNameComponents *nameComponents = [[NSPersonNameComponents alloc] init];
nameComponents.nickname = content.title;
INPersonHandle *handle = [[INPersonHandle alloc] initWithValue:nil type:INPersonHandleTypeUnknown];
INPerson *messageSender = [[INPerson alloc] initWithPersonHandle:handle
nameComponents:nameComponents
displayName:content.title
image:avatarImage
contactIdentifier:nil
customIdentifier:customIdentifier
isMe:NO
suggestionType:(INPersonSuggestionTypeNone)];
INSpeakableString *speakableString = [[INSpeakableString alloc] initWithSpokenPhrase:content.subtitle.length ? content.subtitle : @""];
INSendMessageIntent *intent = [[INSendMessageIntent alloc] initWithRecipients:@[messageSender]
outgoingMessageType:(INOutgoingMessageTypeOutgoingMessageText)
content:content.body
speakableGroupName:speakableString
conversationIdentifier:identifier
serviceName:nil
sender:messageSender
attachments:nil];
[intent setImage:avatarImage forParameterNamed:@"speakableGroupName"];
INInteraction *interaction = [[INInteraction alloc]initWithIntent:intent response:nil];
interaction.direction = INInteractionDirectionIncoming;
[interaction donateInteractionWithCompletion:nil];
UNNotificationContent *_content = [content contentByUpdatingWithProvider:intent error:nil];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier
content:_content
trigger:trigger];
[UNUserNotificationCenter.currentNotificationCenter addNotificationRequest:request withCompletionHandler:completionHandler];`
