iOS 10以后，苹果统一使用 UNUserNotifications ，以前的API都被标为弃用了。(如application:didReceiveRemoteNotification:)
注册通知
使用UNUserNotificationCenter需要引用头文件
#ifdef NSFoundationVersionNumber_iOS_9_x_Max
#import <UserNotifications/UserNotifications.h>
#endif
检查是否有push推送权限
// 检查是否有push推送权限
- (void)checkCurrentNotificationStatus{
if (@available(iOS 10 , *)){
[[UNUserNotificationCenter currentNotificationCenter] getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
if (settings.authorizationStatus == UNAuthorizationStatusNotDetermined){
// 未选择
}else if (settings.authorizationStatus == UNAuthorizationStatusDenied){
// 没权限
}else if (settings.authorizationStatus == UNAuthorizationStatusAuthorized){
// 已授权
[self requestNotification];
}
}];
}
else if (@available(iOS 8 , *))
{
UIUserNotificationSettings * setting = [[UIApplication sharedApplication] currentUserNotificationSettings];
if (setting.types == UIUserNotificationTypeNone) {
// 没权限
}else{
// 已授权
[self requestNotification];
}
}
else{
UIRemoteNotificationType type = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (type == UIUserNotificationTypeNone)
{
// 没权限
}
}
}
消息权限弹窗
//消息权限弹窗
- (void)showUserNotificationAlert {
//弹窗提示，是否开通通知权限
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:@"您需要开启系统通知权限，才可以正常接收消息，请到设置->通知中开启【XXX】消息通知。" preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
}]];
[alert addAction:[UIAlertAction actionWithTitle:@"去设置" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
NSURL * url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
dispatch_async(dispatch_get_main_queue(), ^{
if ([[UIApplication sharedApplication] canOpenURL:url]) {
[[UIApplication sharedApplication] openURL:url];
}
});
}]];
[self presentViewController:alert animated:YES completion:nil];
}
注册消息通知
注意：iOS10以后的api
UNUserNotificationCenter在request调用后就立马回调deviceToken的代理方法，不会等待点击结果，需要注意运行时序的问题，所以项目里加了一个通知方法，点击后再上传deviceToken
//注册消息通知
-(void)requestNotification
{
//ios 10的实现方法出现弹窗的时候就会回调didRegisterForRemoteNotificationsWithDeviceToken，不去等待异步结果
if (@available(iOS 10, *))
{
UNUserNotificationCenter * center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionSound completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted) {
// 允许推送
NSLog(@"注册通知成功");
//点击确认后再次上传deviceToken
[[NSNotificationCenter defaultCenter] postNotificationName:@"requestNotificationSuccess" object:nil];
}else{
//不允许
}
}];
}
//ios 8的实现方法只有点击了同意或不同意按钮才回调didRegisterForRemoteNotificationsWithDeviceToken，等待结果后才回调
else if(@available(iOS 8 , *))
{
UIApplication * application = [UIApplication sharedApplication];
[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]];
}
else
{
UIApplication * application = [UIApplication sharedApplication];
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound];
}
// 注册获得device Token
dispatch_async(dispatch_get_main_queue(), ^{
[[UIApplication sharedApplication] registerForRemoteNotifications];
});
}
系统通知的回调方法
deviceToken(在注册成功后进行回调，每次启动都要注册一次registerForRemoteNotifications)
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
//deviceToken
}
接收通知方法
/*
1.已弃用。iOS 3.0–10.0的版本，消息到达时被回调
2.只有在程序处于运行状态（前台or后台）调用，但是你强制杀死程序之后，来了远程推送，系统不会自动进入你的程序，这个时候application:didReceiveRemoteNotification:就不会被调用。
3.如果实现了application: didReceiveRemoteNotification: fetchCompletionHandler:则该方法不会被调用（如果没有实现就会调用这个，属于系统的兜底逻辑）
*/
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
NSLog(@"%@",userInfo[@"url"]);
}
/*
1.当程序launch完毕之后，就会调用（>iOS7版本）
2.应用在前后台，kill掉的状态在收到推送都会触发该方法（应用kill时，用户点击push后，appFinishLaunch中会带着push消息，同时这个接口也会被调用）
3.即收到消息就会触发，所以要判断前后台状态
4.在ios10后如果设置代理UNUserNotificationCenterDelegate，并实现了willPresentNotification，应用在前台时该方法会变为只有点击时候才触发，收到推送的时候会触发willPresentNotification方法来控制显示效果，如果还实现了代理的点击方法didReceiveNotificationResponse，那么该方法不会触发。
*/
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
NSLog(@"%@",userInfo[@"url"]);
}
//本地推送触发方法
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
NSLog(@"%@",notification.userInfo[@"url"]);
}
iOS10后新的api
代理方法
<UNUserNotificationCenterDelegate>
设置代理
注意：这个代理只能在application里设置 (这也是为什么有一些app设置了
[UNUserNotificationCenter currentNotificationCenter].delegate代理没有触发代理方法的原因)
// The delegate can only be set from an application
// 官方解释，这个代理只能在application里设置
// iOS10后通知前台显示需要设置该代理
[UNUserNotificationCenter currentNotificationCenter].delegate = self;
设置代理后通知的显示方法
如果没有实现这个回调，无论接收到通知和点击通知都会触发
application:didReceiveRemoteNotification:fetchCompletionHandler:方法，但实现了willPresentNotification方法后，didReceiveRemoteNotification只负责点击事件，在前台接收到PUSH后由willPresentNotification处理
#pragma mark UNUserNotificationCenterDelegate代理方法
//当应用在前台时，收到通知会触发这个代理方法
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
// 前台显示，需要执行这个方法，选择是否提醒用户，有Badge、Sound、Alert三种类型可以设置, 不设置alert当APP在前台时就没有提示
completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge);
}
点击推送消息后回调
如果实现了这个回调，则ios10以后的机型上不会触发
application:didReceiveRemoteNotification:fetchCompletionHandler:方法，只会触发下面代理方法，如果没设置代理代码，则去触发didReceiveRemoteNotification方法
//点击推送消息后回调
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)(void))completionHandler{
NSLog(@"Userinfo %@",response.notification.request.content.userInfo);
}
本地PUSH
- (void)localNotification{
if (@available(iOS 10.0, *)) {
NSString *requestID = @"123hhhh";
//第一步：获取推送通知中心
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert|UNAuthorizationOptionSound|UNAuthorizationOptionBadge)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!error) {
NSLog(@"succeeded!");
}
}];
center.delegate = self;
//第二步：设置推送内容
UNMutableNotificationContent *content = [UNMutableNotificationContent new];
content.title = @"推送中心标题";
content.subtitle = @"副标题";
content.body = @"这是UNUserNotificationCenter信息中心";
content.badge = @20;
content.categoryIdentifier = @"categoryIdentifier";
UNNotificationAction *action = [UNNotificationAction actionWithIdentifier:@"enterApp"
title:@"进入应用"
options:UNNotificationActionOptionForeground];
UNNotificationAction *clearAction = [UNNotificationAction actionWithIdentifier:@"destructive"
title:@"忽略2"
options:UNNotificationActionOptionDestructive];
UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"categoryIdentifier"
actions:@[action,clearAction]
intentIdentifiers:@[requestID]
options:UNNotificationCategoryOptionNone];
[center setNotificationCategories:[NSSet setWithObject:category]];
//第三步：设置推送方式
UNTimeIntervalNotificationTrigger *timeTrigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60 repeats:YES];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:requestID content:content trigger:timeTrigger];
//第四步：添加推送request
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
}];
//移除推送
[center removePendingNotificationRequestsWithIdentifiers:@[requestID]];
[center removeAllDeliveredNotifications];
}
}
