1、在项目 target 中,打开Capabilitie —> Push Notifications
,并会自动在项目中生成 .entitlement 文件。(很多同学升级后,获取不到 deviceToken,大概率是由于没开这个选项)
Capabilitie —> Push Notifications
自动生成 .entitlement
2、确保添加了 UserNotifications.framework
,并 import
到 AppDelegate
,记得实现 UNUserNotificationCenterDelegate
。
#import @interface AppDelegate : UIResponder @end
3、在 didFinishLaunchingWithOptions
方法中,首先实现 UNUserNotificationCenter delegate
,并使用 UIUserNotificationSettings
请求权限。
//注意,关于 iOS10 系统版本的判断,可以用下面这个宏来判断。不能再用截取字符的方法。 #define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending) -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{ if(SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(@"10.0")){ UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; center.delegate = self; [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){ if( !error ){ [[UIApplication sharedApplication] registerForRemoteNotifications]; } }]; } return YES; }
4、最后实现以下两个回调。
//====================For iOS 10==================== -(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{ NSLog(@"Userinfo %@",notification.request.content.userInfo); //功能:可设置是否在应用内弹出通知 completionHandler(UNNotificationPresentationOptionAlert); } //点击推送消息后回调 -(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{ NSLog(@"Userinfo %@",response.notification.request.content.userInfo); }
注意:需要根据系统版本号来判断是否使用新的 UserNotifications.framework
,因此,不要着急删除 iOS 10 以前的代码。
