1.首先需要导入UserNotifications.framework框架；
2.在Appdelegate.m中的- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中注册本地推送：[self registerAPN]；
//注册本地推送
- (void)registerAPN {
// if (@available(iOS 10.0, *)) { // iOS10 以上
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate=self;
UNAuthorizationOptions types=UNAuthorizationOptionBadge|UNAuthorizationOptionAlert|UNAuthorizationOptionSound;
[centerrequestAuthorizationWithOptions:typescompletionHandler:^(BOOLgranted,NSError*_Nullableerror) {
}];
}
3.代码实现本地推送
-(void)addLocationNotifitionWithFrencyWith:(NSString *)text
{
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.title=@"本地推送";
content.subtitle= text;
content.sound= [UNNotificationSound defaultSound];
content.userInfo=@{@"type":@"333"};
content.badge=@1;
//多少时间之后发送本地推送
NSTimeInterval time = [[NSDate dateWithTimeIntervalSinceNow:0.5] timeIntervalSinceNow];
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:time repeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"iiid" content:content trigger:trigger];
//把通知加到UNUserNotificationCenter, 到指定触发点会被触发
[centeraddNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if(error) {
NSLog(@"通知添加失败:%@",error);
}else{
NSLog(@"通知添加成功");
}
}];
}
4.在UNUserNotificationCenter的delegate方法中添加点击推送之后的操作
#warning 前台收到推送
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
NSLog(@"点开推送啦啦啦");
}
#warning 后台点击推送
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
{
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;//消掉小红点
NSDictionary *userInfo = response.notification.request.content.userInfo;
NSLog(@"收到推送\n详细内容：%@",userInfo);
}
5.移除本地推送
（1） //移除所有的推送通知
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[centerremoveAllPendingNotificationRequests];
（2）移除某一个推送：根据UNNotificationRequest的identifier 找到特定的推送请求，再移除
-(void)removeOneNotificationWithID:(NSString*)noticeId
{
UNUserNotificationCenter*center=[UNUserNotificationCenter currentNotificationCenter];
[center getPendingNotificationRequestsWithCompletionHandler: ^(NSArray<UNNotificationRequest*>*_Nonnull requests)
{
for(UNNotificationRequest*req in requests)
{
NSLog(@"The exist IDs:%@\n",req.identifier);
}
NSLog(@"Remove currentID:%@",noticeId);
}];
[center removePendingNotificationRequestsWithIdentifiers:@[noticeId]];
}
