iOS10全新推送功能的实现

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



或许还应该打开这个



#import <UserNotifications/UserNotifications.h>

- (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

#pragma mark -

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings NS_AVAILABLE_IOS(8_0) __TVOS_PROHIBITED{
NSLog(@"didRegisterUserNotificationSettings");
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken NS_AVAILABLE_IOS(3_0){
NSLog(@"deviceToken:%@",deviceToken);
NSString *deviceTokenSt = [[[[deviceToken description]
stringByReplacingOccurrencesOfString:@"<" withString:@""]
stringByReplacingOccurrencesOfString:@">" withString:@""]
stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"deviceTokenSt:%@",deviceTokenSt);
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error NS_AVAILABLE_IOS(3_0){
NSLog(@"didFailToRegisterForRemoteNotificationsWithError:%@",error);
}

/*iOS9使用方法
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo NS_DEPRECATED_IOS(3_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate willPresentNotification:withCompletionHandler:] or -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:] for user visible notifications and -[UIApplicationDelegate application:didReceiveRemoteNotification:fetchCompletionHandler:] for silent remote notifications"){

}
*/

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
NSLog(@"willPresentNotification:%@",notification.request.content.title);

// 这里真实需要处理交互的地方
// 获取通知所带的数据
NSString *notMess = [notification.request.content.userInfo objectForKey:@"aps"];

}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
//在没有启动本App时，收到服务器推送消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮
NSString *notMess = [response.notification.request.content.userInfo objectForKey:@"aps"];
NSLog(@"didReceiveNotificationResponse:%@",response.notification.request.content.title);
//    response.notification.request.identifier
}

//远程推送APP在前台
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
NSLog(@"didReceiveRemoteNotification:%@",userInfo);
}

/*
- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler NS_DEPRECATED_IOS(8_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:]") __TVOS_PROHIBITED
{

}
*/
/*
// 本地通知回调函数，当应用程序在前台时调用
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification NS_DEPRECATED_IOS(4_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate willPresentNotification:withCompletionHandler:] or -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:]") __TVOS_PROHIBITED{
NSLog(@"didReceiveLocalNotification:%@",notification.userInfo);

// 这里真实需要处理交互的地方
// 获取通知所带的数据
NSString *notMess = [notification.userInfo objectForKey:@"aps"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"本地通知(前台)"
message:notMess
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];

// 更新显示的徽章个数
NSInteger badge = [UIApplication sharedApplication].applicationIconBadgeNumber;
badge--;
badge = badge >= 0 ? badge : 0;
[UIApplication sharedApplication].applicationIconBadgeNumber = badge;

// 在不需要再推送时，可以取消推送
[FirstViewController cancelLocalNotificationWithKey:@"key"];

}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler NS_DEPRECATED_IOS(8_0, 10_0, "Use UserNotifications Framework's -[UNUserNotificationCenterDelegate didReceiveNotificationResponse:withCompletionHandler:]") __TVOS_PROHIBITED
{
//在非本App界面时收到本地消息，下拉消息会有快捷回复的按钮，点击按钮后调用的方法，根据identifier来判断点击的哪个按钮，notification为消息内容
NSLog(@"%@----%@",identifier,notification);
completionHandler();//处理完消息，最后一定要调用这个代码块
}
*/

还有推送插件开发: 类似iOS tody widget插件开发

   这里我们要注意一定要有"mutable-content": "1",以及一定要有Alert的字段，否则可能会拦截通知失败。（苹果文档说的）。除此之外，我们还可以添加自定义字段，比如，图片地址，图片类型
{
"aps": {
"alert": "message.",
"badge": 1,
"sound": "default",
"mutable-content": "1",
"imageAbsoluteString": "http://xxxx"

}
}
