如何在应用程序处于后台时处理iOS远程通知
问题描述:
我正在通过苹果推送通知在iOS推送通知功能上工作,现在我正在通知应用程序处于后台或前台,但我想处理远程通知当我的应用程序在后台时,基本上当我的应用程序在后台时,它只是显示来自有效内容的警报消息。实际上,我只是想自定义我的远程通知。如何在应用程序处于后台时处理iOS远程通知
代码:
- (BOOL)application:(UIApplication)application didFinishLaunchingWithOptions:(NSDictionary)launchOptions {
// Override point for customization after application launch.
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
// [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
return YES;
}
- (void)application:(UIApplication *)application
didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
NSLog(@"Did Register for Remote Notifications with Device Token (%@)", error);
}
- (void)application:(UIApplication)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData)deviceToken {
NSLog(@"Did Register for Remote Notifications with Device Token (%@)", deviceToken);
}
-(void)application:(UIApplication)application didReceiveRemoteNotification:(NSDictionary)userInfo fetchCompletionHandler:(void (UIBackgroundFetchResult))completionHandler
{
NSDictionary * aps=[userInfo valueForKey"aps"];
NSLog(@"did recevie %@",aps);
NSLog(@"userinfo details %@",[aps valueForKey"alert"]);
}
答
在iOS中10首先你要设置UNUserNotificationCenterDelegate
在AppDelegate.h
文件
@interface AppDelegate : UIResponder <UIApplicationDelegate,CLLocationManagerDelegate,UNUserNotificationCenterDelegate>
后,在AppDelegate.m
这样写代码
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.1) {
// iOS 7.1 or earlier. Disable the deprecation warnings.
UIRemoteNotificationType allNotificationTypes =
(UIRemoteNotificationTypeSound |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeBadge);
[application registerForRemoteNotificationTypes:allNotificationTypes];
[[UIApplication sharedApplication] registerForRemoteNotifications];
} else {
// iOS 8 or later
// [START register_for_notifications]
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 9.0)
{
UIUserNotificationType allNotificationTypes =
(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings =
[UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
[[UIApplication sharedApplication] registerForRemoteNotifications];
[application registerForRemoteNotifications];
} else {
// iOS 10 or later
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
UNAuthorizationOptions authOptions =
UNAuthorizationOptionAlert
| UNAuthorizationOptionSound
| UNAuthorizationOptionBadge;
[[UNUserNotificationCenter currentNotificationCenter]
requestAuthorizationWithOptions:authOptions
completionHandler:^(BOOL granted, NSError * _Nullable error) {
}
];
// For iOS 10 display notification (sent via APNS)
[[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];
[[UIApplication sharedApplication] registerForRemoteNotifications];
return YES;
}
现在实现这个方法适用于iOS10以下版本
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))handler {
NSLog(@"Notification received: %@", userInfo);
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10.0"))
{
NSLog(@"iOS version >= 10. Let NotificationCenter handle this one.");
return;
}
NSLog(@"HANDLE PUSH, didReceiveRemoteNotification: %@", userInfo);
else{
handler(UIBackgroundFetchResultNewData);
}
}
Apple在iOS10中引入了这两种方法来接收推送通知。
写这些方法也
// Receive displayed notifications for iOS 10 devices.
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
willPresentNotification:(UNNotification *)notification
withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {
NSDictionary *userInfo = notification.request.content.userInfo;
NSLog(@"%@", userInfo);
completionHandler(UNNotificationPresentationOptionAlert);
}
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
NSLog(@"Userinfo %@",response.notification.request.content.userInfo);
// completionHandler(UNNotificationPresentationOptionAlert);
}
就是这样。

您正在测试设备中使用哪个版本的iOS? – Himanth
对于iOS 10及以上版本,你必须做一些其他的东西 – Himanth
它是在ios 10.0 –
