【中文标题】Objective-C 中的 iOS 10 富媒体推送通知（媒体附件）【英文标题】：iOS 10 Rich Media Push Notification (Media Attachment) in Objective-C 【发布时间】：2016-09-24 07:23:12 【问题描述】：我想在 ios 10 推送通知中添加媒体，尤其是图像和视频，但图像在推送中不起作用。如何在 Objective-C 中做到这一点？我的代码如下：
AppDelegate.h
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#import <UserNotifications/UserNotifications.h>
@interface AppDelegate : UIResponder <UIApplicationDelegate,CLLocationManagerDelegate,UNUserNotificationCenterDelegate>
@property (strong, nonatomic) UIWindow *window;
@end
AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
if(SYSTEM_VERSION_LESS_THAN( @"10.0" ))
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
else
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error)
if( !error )
[[UIApplication sharedApplication] registerForRemoteNotifications];
// required to get the app to do anything at all about push notifications
NSLog( @"Push registration success." );
else
NSLog( @"Push registration FAILED" );
NSLog( @"ERROR: %@ - %@", error.localizedFailureReason, error.localizedDescription );
NSLog( @"SUGGESTIONS: %@ - %@", error.localizedRecoveryOptions, error.localizedRecoverySuggestion );
];
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
NSString * token = [NSString stringWithFormat:@"%@", deviceToken];
//Format token as per need:
token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
NSLog(@"Device Token is \n%@",token);
-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
NSLog(@"Error:%@",error);
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO( @"10.0" ))
[self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:^(UIBackgroundFetchResult result)];
else
/// previous stuffs for iOS 9 and below. I've shown an alert wth received data.
-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void(^)(UIBackgroundFetchResult))completionHandler
// iOS 10 will handle notifications through other methods
if( NOTIFY_VISITORS_SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO( @"10.0" ) )
NSLog( @"iOS version >= 10. Let NotificationCenter handle this one." );
// set a member variable to tell the new delegate that this is background
return;
NSLog( @"HANDLE PUSH, didReceiveRemoteNotification: %@", userInfo );
// custom code to handle notification content
if( [UIApplication sharedApplication].applicationState == UIApplicationStateInactive )
NSLog( @"INACTIVE" );
completionHandler( UIBackgroundFetchResultNewData );
else if( [UIApplication sharedApplication].applicationState == UIApplicationStateBackground )
NSLog( @"BACKGROUND" );
completionHandler( UIBackgroundFetchResultNewData );
else
NSLog( @"FOREGROUND" );
completionHandler( UIBackgroundFetchResultNewData );
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
NSLog( @"Handle push from foreground" );
// custom code to handle push while app is in the foreground
NSLog(@"%@", notification.request.content.userInfo);
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
NSLog( @"Handle push from background or closed" );
// if you set a member variable in didReceiveRemoteNotification, you will know if this is from closed or background
NSLog(@"%@", response.notification.request.content.userInfo);
然后我添加了一个新的目标通知服务扩展如下：
NotificationService.h
#import <UserNotifications/UserNotifications.h>
@interface NotificationService : UNNotificationServiceExtension
@end
NotificationService.m
#import "NotificationService.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];
// Modify the notification content here...
//self.bestAttemptContent.body = [NSString stringWithFormat:@"%@ [modified]", self.bestAttemptContent.body];
// check for media attachment, example here uses custom payload keys mediaUrl and mediaType
NSDictionary *userInfo = request.content.userInfo;
if (userInfo == nil)
[self contentComplete];
return;
NSString *mediaUrl = userInfo[@"mediaUrl"];
NSString *mediaType = userInfo[@"mediaType"];
if (mediaUrl == nil || mediaType == nil)
[self contentComplete];
return;
// load the attachment
[self loadAttachmentForUrlString:mediaUrl
withType:mediaType
completionHandler:^(UNNotificationAttachment *attachment)
if (attachment)
self.bestAttemptContent.attachments = [NSArray arrayWithObject:attachment];
[self contentComplete];
];
- (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
self.contentHandler(self.bestAttemptContent);
- (NSString *)fileExtensionForMediaType:(NSString *)type
NSString *ext = type;
if ([type isEqualToString:@"image"])
ext = @"jpg";
if ([type isEqualToString:@"video"])
ext = @"mp4";
if ([type isEqualToString:@"audio"])
ext = @"mp3";
return [@"." stringByAppendingString:ext];
- (void)loadAttachmentForUrlString:(NSString *)urlString withType:(NSString *)type completionHandler:(void(^)(UNNotificationAttachment *))completionHandler
__block UNNotificationAttachment *attachment = nil;
NSURL *attachmentURL = [NSURL URLWithString:urlString];
NSString *fileExt = [self fileExtensionForMediaType:type];
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:fileExt]];
[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
我的通知服务扩展 Info.plist 是：
我正在使用 php 脚本发送推送通知，如下所示：
TestPush.php
<?php
// Put your device token here (without spaces):
$deviceToken = 'my device tocken goes here';
// Put your private key's passphrase here:
$passphrase = 'mypassphase';
// Put your alert message here:
$message = 'Test iOS 10 Media Attachment Push';
////////////////////////////////////////////////////////////////////////////////
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
stream_context_set_option($ctx, 'ssl', 'cafile', 'entrust_2048_ca.cer');
// Open a connection to the APNS server
$fp = stream_socket_client(
'ssl://gateway.sandbox.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp)
exit("Failed to connect: $err $errstr" . PHP_EOL);
echo 'Connected to APNS' . PHP_EOL;
// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'default',
'mutable-content' => 1,
'category'=> "pusher"
);
$body['data'] = array(
'mediaUrl' => "http://www.alphansotech.com/wp-content/uploads/2015/12/Push-notification-1.jpg",
'mediaType' => "jpg"
);
// Encode the payload as JSON
$payload = json_encode($body);
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
if (!$result)
echo 'Message not delivered' . PHP_EOL;
else
echo 'Message successfully delivered' . PHP_EOL;
// Close the connection to the server
fclose($fp);
共享图像和文件托管在服务器上，推送将发送其链接以显示它。
谁能帮帮我。
【问题讨论】：
您好，我也在尝试在 Objective-C 上实现此功能，但在网上找不到任何资源...您能否分享您的代码和/或指向您的资源的链接用过的？谢谢！ 上面的代码工作正常，只有音频和视频不能正常工作。只需更改有效负载格式，请参阅this question 的第一个答案。如果您找到任何支持音频和视频的解决方案，请也参考我该解决方案。 我已经实现了上面的代码和有效负载，但它没有完全工作，我认为它与 info.plist 有关，因为我在你的屏幕截图中看不到键名。 是NotificationServiceExtension部分的info.plist，源码为：<key>NSExtension</key> <dict><key>NSExtensionAttributes</key> <dict> <key>UNNotificationExtensionCategory</key> <string>myCat</string> <key>UNNotificationExtensionInitialContentSizeRatio</key> <real>0.7</real> <key>UNNotificationExtensionDefaultContentHidden</key> <true/> </dict> <key>NSExtensionPointIdentifier</key> <string>com.apple.usernotifications.service</string> <key>NSExtensionPrincipalClass</key> <string>NotificationService</string> </dict>
在这个 plist 中有一个键 UNNotificationExtensionCategory 它没有在我的代码中用于 ow 但我认为它是音频和视频支持所必需的。我正在尝试这样做，我当我得到解决方案时会更新你。如果你能解决问题，请更新我。谢谢！！
【参考方案1】：
此不起作用的其他警告是拥有通知服务
Deployment Target 值您的测试设备不支持。
在我的例子中，通知服务模板自动将其Deployment Target 设置为10.2，而我的测试设备是10.1
我浪费了几个小时来配置我的扩展程序设置，而它一直在工作！
【讨论】：
也被这个抓住了。 这很有帮助。谢谢 超级兄弟。节省了一天。【参考方案2】：您的代码没问题，只是需要不同的推送通知数据格式：
尝试更换这部分：
// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'default',
'mutable-content' => 1,
'category'=> "pusher"
);
$body['data'] = array(
'mediaUrl' => "http://www.alphansotech.com/wp-content/uploads/2015/12/Push-notification-1.jpg",
'mediaType' => "jpg"
);
与：
$body = array(
'aps' => array(
'alert' => 'Rich notification',
'sound' => 'default',
'mutable-content' => 1
),
'mediaUrl' => 'https://upload.wikimedia.org/wikipedia/commons/thumb/2/2a/FloorGoban.JPG/1024px-FloorGoban.JPG',
'mediaType' => 'image'
);
请注意，该图片应该可以通过https://访问
【讨论】：
它工作正常，但我在提供嵌入代码链接时无法播放 youtube 视频。我想更新应该支持所有图像、视频和音频格式的代码。 我想在推送中播放视频，但上面的代码不支持如何做到这一点，你能帮我从上面的代码中播放视频吗？ @Ashraf 能否提供任何示例演示链接以了解丰富推送通知的使用和项目创建？？ 查看推送通知中富媒体附件的演示see this link 完美答案。以上是关于Objective-C 中的 iOS 10 富媒体推送通知（媒体附件）的主要内容，如果未能解决你的问题，请参考以下文章
