从iOS8.0开始推送功能的实现在不断改变，功能也在不断增加，iOS10又出来了一个推送插件的开发（见最后图），废话不多说直接上代码：
在开始之前需要打开一个推送开关,不然无法获取deviceToken,老项目或者出现deviceToken无效的情况：如图：
打开后会生成entitlements文件，需要有APS Environment
#import- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. /* APP未启动，点击推送消息的情况下 iOS10遗弃UIApplicationLaunchOptionsLocalNotificationKey，使用代理UNUserNotificationCenterDelegate方法didReceiveNotificationResponse:withCompletionHandler:获取本地推送 */// NSDictionary *localUserInfo = launchOptions[UIApplicationLaunchOptionsLocalNotificationKey];// if (localUserInfo) {// NSLog(@"localUserInfo:%@",localUserInfo);// //APP未启动，点击推送消息// } NSDictionary *remoteUserInfo = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]; if (remoteUserInfo) { NSLog(@"remoteUserInfo:%@",remoteUserInfo); //APP未启动，点击推送消息，iOS10下还是跟以前一样在此获取 } [self registerNotification]; return YES;}
注册推送方法的改变：
新增库 #import <UserNotifications/UserNotifications.h> 推送单列UNUserNotificationCenter 等API
- (void)registerNotification{ /* identifier：行为标识符，用于调用代理方法时识别是哪种行为。 title：行为名称。 UIUserNotificationActivationMode：即行为是否打开APP。 authenticationRequired：是否需要解锁。 destructive：这个决定按钮显示颜色，YES的话按钮会是红色。 behavior：点击按钮文字输入，是否弹出键盘 */ UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:@"action1" title:@"策略1行为1" options:UNNotificationActionOptionForeground]; /*iOS9实现方法 UIMutableUserNotificationAction * action1 = [[UIMutableUserNotificationAction alloc] init]; action1.identifier = @"action1"; action1.title=@"策略1行为1"; action1.activationMode = UIUserNotificationActivationModeForeground; action1.destructive = YES; */ UNTextInputNotificationAction *action2 = [UNTextInputNotificationAction actionWithIdentifier:@"action2" title:@"策略1行为2" options:UNNotificationActionOptionDestructive textInputButtonTitle:@"textInputButtonTitle" textInputPlaceholder:@"textInputPlaceholder"]; /*iOS9实现方法 UIMutableUserNotificationAction * action2 = [[UIMutableUserNotificationAction alloc] init]; action2.identifier = @"action2"; action2.title=@"策略1行为2"; action2.activationMode = UIUserNotificationActivationModeBackground; action2.authenticationRequired = NO; action2.destructive = NO; action2.behavior = UIUserNotificationActionBehaviorTextInput;//点击按钮文字输入，是否弹出键盘 */ UNNotificationCategory *category1 = [UNNotificationCategory categoryWithIdentifier:@"Category1" actions:@[action2,action1] intentIdentifiers:@[@"action1",@"action2"] options:UNNotificationCategoryOptionCustomDismissAction]; // UIMutableUserNotificationCategory * category1 = [[UIMutableUserNotificationCategory alloc] init]; // category1.identifier = @"Category1"; // [category1 setActions:@[action2,action1] forContext:(UIUserNotificationActionContextDefault)]; UNNotificationAction *action3 = [UNNotificationAction actionWithIdentifier:@"action3" title:@"策略2行为1" options:UNNotificationActionOptionForeground]; // UIMutableUserNotificationAction * action3 = [[UIMutableUserNotificationAction alloc] init]; // action3.identifier = @"action3"; // action3.title=@"策略2行为1"; // action3.activationMode = UIUserNotificationActivationModeForeground; // action3.destructive = YES; UNNotificationAction *action4 = [UNNotificationAction actionWithIdentifier:@"action4" title:@"策略2行为2" options:UNNotificationActionOptionForeground]; // UIMutableUserNotificationAction * action4 = [[UIMutableUserNotificationAction alloc] init]; // action4.identifier = @"action4"; // action4.title=@"策略2行为2"; // action4.activationMode = UIUserNotificationActivationModeBackground; // action4.authenticationRequired = NO; // action4.destructive = NO; UNNotificationCategory *category2 = [UNNotificationCategory categoryWithIdentifier:@"Category2" actions:@[action3,action4] intentIdentifiers:@[@"action3",@"action4"] options:UNNotificationCategoryOptionCustomDismissAction]; // UIMutableUserNotificationCategory * category2 = [[UIMutableUserNotificationCategory alloc] init]; // category2.identifier = @"Category2"; // [category2 setActions:@[action4,action3] forContext:(UIUserNotificationActionContextDefault)]; [[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObjects:category1,category2, nil]]; [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) { NSLog(@"completionHandler"); }]; /*iOS9实现方法 UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound) categories:[NSSet setWithObjects: category1,category2, nil]]; [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; */ [[UIApplication sharedApplication] registerForRemoteNotifications]; [UNUserNotificationCenter currentNotificationCenter].delegate = self;} 代理方法的改变：
一些本地和远程推送的回调放在了同一个代理方法
