本地推送闹钟功能实现
在ios10下使用UserNotifications用本地推送实现闹钟功能，只是实现了简单的定时推送功能。
只适用于ios10以上系统，ios10以后apple对推送重新进行了封装，
更加统一。
Step 1
在AppDelegate.h里注册推送：
- (void)registerUserNotification
{
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:UNAuthorizationOptionSound |
UNAuthorizationOptionAlert | UNAuthorizationOptionBadge completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (error) {
NSLog(@"%@",error);
}
}];
}
ios10以上对于收到推送的处理与之前有很大区别，ios10以上需要实现UNUserNotificationCenterDelegate两个方法
app在前台收到推送
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert);
}
处理用户点击推送
分为两种情况
- 点击推送打开app
- 点击推送的操作（下图的点赞操作）
second
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
{
NSString *categoryIdentify = response.notification.request.content.categoryIdentifier;
if ([categoryIdentify isEqualToString:@"closeCategory"]) {
if ([response.actionIdentifier isEqualToString:@"closeAlarmIdentify"]) {
//操作Identify
self.window.rootViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"ViewController"];
}
}
completionHandler();
}
Step 2
在需要的地方添加推送
配置需要推送的content，UNMutableNotificationContent有很多属性，title，subtitle，sound，userInfo ...
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.title = @"打卡";
content.body = @"马上去打卡";
content.badge = @1;
content.sound = [UNNotificationSound soundNamed:@"4084.wav"];
content.categoryIdentifier = @"closeCategory";
如果需要执行操作可以进行如下配置
UNNotificationAction *closeAction = [UNNotificationAction actionWithIdentifier:@"closeAlarmIdentify" title:@"关闭" options:UNNotificationActionOptionForeground];
UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"closeCategory" actions:@[closeAction] intentIdentifiers:@[] options:UNNotificationCategoryOptionNone];
[center setNotificationCategories:[NSSet setWithArray:@[category]]];
Step 3
设置提醒时间，有三种方式可以进行设置
-
UNTimeIntervalNotificationTrigger多长时间之后发送推送 -
UNCalendarNotificationTrigger根据日历推送 -
UNLocationNotificationTrigger根据位置推送
代码分别如下:
UNTimeIntervalNotificationTrigger *trigger1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO];//timeInterval单位为秒
//每周一下午 6：00 打卡
NSDateComponents *components = [[NSDateComponents alloc] init];
components.weekday = 2;
components.hour = 18;
UNCalendarNotificationTrigger *trigger2 = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:YES];
NSDateComponents 的weekday属性对应转换关系如下
- (NSString *)getWeekDayWithIntegerDay:(NSInteger)weekday andSunDayType:(NSInteger)type
{
NSString* weekString;
switch (weekday) {
case 1:
weekString = type?@"7":@"日";
break;
case 2:
weekString = type?@"1":@"一";
break;
case 3:
weekString = type?@"2":@"二";
break;
case 4:
weekString = type?@"3":@"三";
break;
case 5:
weekString = type?@"4":@"四";
break;
case 6:
weekString = type?@"5":@"五";
break;
case 7:
weekString = type?@"6":@"六";
break;
}
return weekString
}
Step 4
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if (error) {
NSLog(@"%@",error);
}else
{
UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"添加成功" message:nil preferredStyle:UIAlertControllerStyleAlert];
[alertVC addAction:[UIAlertAction actionWithTitle:@"好的" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
}]];
[self presentViewController:alertVC animated:YES completion:nil];
}
}];
结语
由于ios系统限制，推送声音最多提示30秒。本来想要程序一直在后台运行，等收到本地推送的时候执行自己的代码，但是一直没有成功，有想法的可以在评论里讨论。
