UserNotification ios 10

Question

我想在UserNotification（本地通知）中显示gif动画，但我只能在用户通知中显示图像，动画不会显示。 （UNNotificationRequest *）要求 withContentHandler：：（无效（无效）didReceiveNotificationRequest - 我在Objective-C

我的代码 //调度的通知

NSString *UNExtensionID=@"animatedContentExtension"; 
NSError *error; 
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init]; 
content.title = [NSString localizedUserNotificationStringForKey:@"Test Notification:" arguments:nil]; 
content.body = [NSString localizedUserNotificationStringForKey:@"Hello there！It is a multimedia notification with animation!" 
                arguments:nil]; 
content.sound = [UNNotificationSound defaultSound]; 

UNNotificationAttachment *attachment; 
NSURL *url = [[NSBundle mainBundle] URLForResource:@"bike" withExtension:@"png"]; 

attachment=[UNNotificationAttachment attachmentWithIdentifier:@"imageID" 
               URL: url 
              options:nil 
              error:&error]; 
content.attachments=@[attachment]; 
content.categoryIdentifier=UNExtensionID; 

content.badge = @([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1); 
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger 
               triggerWithTimeInterval:20.0f repeats:NO]; 
    UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"FiveSecond" 
                     content:content trigger:trigger]; 


UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; 
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) { 
    if (!error) { 
     NSLog(@"add NotificationRequest succeeded!"); 
    } 
}]; 

//这个代码在AppDelegate中 这样做（^）（UNNotificationContent * contentToDeliver））contentHandler时{

UNNotificationAttachment *attachment; 
NSError *error; 

    UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init]; 
NSURL *url = [[NSBundle mainBundle] URLForResource:@"bike" withExtension:@"png"]; 

attachment=[UNNotificationAttachment attachmentWithIdentifier:@"imageID" 
                  URL:url 
                 options:nil 
                 error:&error]; 
    content=request.content.mutableCopy; 
    content.attachments= @[attachment]; 
    `enter code here`contentHandler(content); 

}

您必须在Notification Service Extension文件中添加您的.gif文件。 您可以创建一个UNNotificationAttachment对象，并通过子类的func didReceiveNotificationRequest(request: UNNotificationRequest, withContentHandler contentHandler: (UNNotificationContent) -> Void)方法的completionHandler。
