IOS 丰富的通知 didReceiveNotificationRequest 没有被触发

问题描述

我正在使用 Objective-c 开发 iPhone 应用程序.基本的推送通知工作正常.现在我想在我的应用程序中添加丰富的通知，但我无法在 NotificationService 中触发 didReceiveNotificationRequest.

I'm developing an iPhone application using objective-c. The basic push notification is working properly. Now I want to add rich notification in my app but I cannot get the didReceiveNotificationRequest fired in the NotificationService.

这是我在 Appdelegate 上收到的通知负载:

Here is the notification payload I receive on Appdelegate:

这是 NotificationService.m 文件；

Here is the NotificationService.m file;

#import "NotificationService.h"
#import "Common.h"

@interface NotificationService ()

@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;

@end

@implementation NotificationService

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
self.contentHandler = contentHandler;
self.bestAttemptContent = [request.content mutableCopy];
NSLog(@"didReceiveNotificationRequest");
// Modify the notification content here...
// load the attachment
NSDictionary *userInfo = request.content.userInfo;
NSString *imageURL = [userInfo valueForKey:@"thumbnail_image"];
NSArray *parts = [imageURL componentsSeparatedByString:@"."];
NSString *extension = [parts lastObject];
[self loadAttachmentForUrlString:imageURL
                        withExtension:extension
               completionHandler:^(UNNotificationAttachment *attachment) {
                   if (attachment) {
                       self.bestAttemptContent.attachments = [NSArray arrayWithObject:attachment];
                   }
                   //self.bestAttemptContent.title = [NSString stringWithFormat:@"%@ [modified]", self.bestAttemptContent.title];

                   self.contentHandler(self.bestAttemptContent);
               }];



}

- (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.contentHandler(self.bestAttemptContent);
}

- (void)loadAttachmentForUrlString:(NSString *)urlString withExtension:(NSString *)extension completionHandler:(void(^)(UNNotificationAttachment *))completionHandler  {

__block UNNotificationAttachment *attachment = nil;
NSURL *attachmentURL = [NSURL URLWithString:urlString];

NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[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:extension]];
                    [fileManager moveItemAtURL:temporaryFileLocation toURL:localURL error:&error];

                    NSError *attachmentError = nil;
                    attachment = [UNNotificationAttachment attachmentWithIdentifier:@"" URL:localURL options:nil error:&attachmentError];
                    if (attachmentError) {
                        NSLog(@"%@", attachmentError.localizedDescription);
                    }
                }
                completionHandler(attachment);
            }] resume];
}

@end

我错过了什么?

推荐答案

您正在后台线程中下载图像，这导致了 Rich Push Notification 案例中的问题.如果你愿意，你可以试试这个框架

You are downloading the image in background thread which is causing the issue in Rich Push Notification case. If you want you can try with this framework

同时在您的 aps

或者你可以尝试像这样下载，

OR you can try downloading like this,

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent *))contentHandler {

    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];

    self.bestAttemptContent.title = [NSString stringWithFormat:@"%@",request.content.title];
    self.bestAttemptContent.body = [NSString stringWithFormat:@"%@",request.content.body];

    NSString *attachmentUrlString = [NSString stringWithFormat:@"%@",[request.content.userInfo valueForKey:@"thumbnail_image"]];

    if (![attachmentUrlString isKindOfClass:[NSString class]]) {
        [self failEarly];
        return;
    }

    NSURL *url = [NSURL URLWithString:attachmentUrlString];
    if (!url) {
        [self failEarly];
        return;
    }

    NSData *data = [NSData dataWithContentsOfURL:url];
    if (!data) {
        [self failEarly];
        return;
    }

    NSString *identifierName = [self getIdentifierName:attachmentUrlString];
    NSString *tmpSubFolderName = [[NSProcessInfo processInfo] globallyUniqueString];

    self.bestAttemptContent.attachments = [NSArray arrayWithObject:[self create:identifierName andData:data withOptions:nil andTmpFolderName:tmpSubFolderName]] ;
    self.contentHandler(self.bestAttemptContent);

}

-(void)failEarly {
    self.contentHandler(self.bestAttemptContent);
}

-(NSString *)getIdentifierName:(NSString *)fileURL
{
    NSString *identifierName = @"image.jpg";

    if (fileURL) {
        identifierName = [NSString stringWithFormat:@"file.%@",fileURL.lastPathComponent];
    }

    return identifierName;
}

-(UNNotificationAttachment *)create:(NSString *)identifier andData:(NSData *)data withOptions:(NSDictionary *)options andTmpFolderName:(NSString *)tmpSubFolderName {

    NSString *fileURLPath = NSTemporaryDirectory();
    NSString *tmpSubFolderURL = [fileURLPath stringByAppendingPathComponent:tmpSubFolderName];
    NSError *error;
    [[NSFileManager defaultManager] createDirectoryAtPath:tmpSubFolderURL withIntermediateDirectories:TRUE attributes:nil error:&error];
    if(!error) {
        NSString *fileURL = [tmpSubFolderURL stringByAppendingPathComponent:identifier];
        [data writeToFile:fileURL atomically:YES];
        UNNotificationAttachment *attachment = [UNNotificationAttachment attachmentWithIdentifier:identifier URL:[NSURL fileURLWithPath:fileURL] options:options error:&error];
        return attachment;
    }
    return nil;
}

- (void)serviceExtensionTimeWillExpire {
    self.contentHandler(self.bestAttemptContent);
}
