问题描述
我已经在我的项目中添加了 UNNotificationServiceExtension 和 UNNotificationContentExtension 以获取丰富的推送通知.
请参考下面我添加的代码.
I've added UNNotificationServiceExtension and UNNotificationContentExtension in my project for rich push notification.
Please refer the code below which i've added for the same.
代码:
#import "NotificationService.h"
@interface NotificationService ()
@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;
@end
@implementation NotificationService {
NSURLSession *session;
}
- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
self.contentHandler = contentHandler;
self.bestAttemptContent = [request.content mutableCopy];
NSDictionary *userInfo = request.content.userInfo;
if (userInfo == nil) {
[self contentComplete];
return;
}
if ([userInfo objectForKey:@"pic_url"]) {
[self loadAttachmentForUrlString:[userInfo objectForKey:@"pic_url"]
completionHandler: ^(UNNotificationAttachment *attachment) {
self.bestAttemptContent.attachments = [NSArray arrayWithObjects:attachment, nil];
}];
}
}
- (void)loadAttachmentForUrlString:(NSString *)urlString
completionHandler:(void (^)(UNNotificationAttachment *))completionHandler
{
__block UNNotificationAttachment *attachment = nil;
__block NSURL *attachmentURL = [NSURL URLWithString:urlString];
NSString *fileExt = [@"." stringByAppendingString:[urlString pathExtension]];
session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionDownloadTask *task = [session downloadTaskWithURL:attachmentURL
completionHandler: ^(NSURL *temporaryFileLocation, NSURLResponse *response, NSError *error) {
if (error != nil)
{
NSLog(@"%@", error.localizedDescription);
}
else
{
NSFileManager *fileManager = [NSFileManager defaultManager];
NSURL *localURL = [NSURL fileURLWithPath:[temporaryFileLocation.path
stringByAppendingString:fileExt]];
[fileManager moveItemAtURL:temporaryFileLocation
toURL:localURL
error:&error];
NSError *attachmentError = nil;
attachment = [UNNotificationAttachment attachmentWithIdentifier:[attachmentURL lastPathComponent]
URL:localURL
options:nil
error:&attachmentError];
if (attachmentError)
{
NSLog(@"%@", attachmentError.localizedDescription);
}
}
completionHandler(attachment);
}];
[task resume];
}
- (void)serviceExtensionTimeWillExpire {
// Called just before the extension will be terminated by the system.
// Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
[self contentComplete];
}
- (void)contentComplete
{
[session invalidateAndCancel];
self.contentHandler(self.bestAttemptContent);
}
@end
我正在使用以下有效负载
I'm using the following payload
{
"to": "9yJUWBA",
"mutable_content": true,
"category": "myNotificationCategory",
"notification":
{
"title":"Realtime Custom Push Notifications",
"subtitle":"Now with iOS 10 support!",
"body":"Add multimedia content to your notifications"
}
}
问题是我没有收到通知.我已经使用以下教程来实现丰富的推送通知.我检查了不同的可用答案，但没有一个对我有用.我还尝试通过附加扩展进程但未触发断点来调试 didReceiveNotificationRequest 方法.
The problem is i'm not getting the notification. I've used the following tutorial for implementing the rich push notification. I've checked different answers available but none of them worked for me. I've also tried to debug the didReceiveNotificationRequest method by attaching the extension process but the breakpoint not triggered.
