通知的原理，在这里就不做过多的解释了，不懂的朋友可以自行Google
这里我们主要说下本地推送。
目前来说本地通知主要分为iOS 10 及 iOS 10以下两种不同方式
iOS 10及其以上的写法
+(void) createNotification
{
//设置通知内容
UNMutableNotificationContent * content = [[UNMutableNotificationContent alloc] init];
content.title = @"推送的标题";
content.body = @"推送的内容";
content.subtitle = @"推送的子标题";
content.badge = [NSNumber numberWithInteger:0];// 红标
content.sound = [UNNotificationSound defaultSound];
//[UNNotificationSound soundNamed:@""]; 自定义推送声音
//给通知添加本地图片或者视频,写法同下
NSString *path = [[NSBundle mainBundle] pathForResource:@"rank2" ofType:@"png"];
NSError *error = nil;
/*
UNNotificationAttachment是指可以包含音频，图像或视频内容。使用本地通知时，可以在通知创建时，将附件加入即可。对于远程通知，则必须实现使用UNNotificationServiceExtension类通知服务扩展。
*/
UNNotificationAttachment *img_attachment = [UNNotificationAttachment attachmentWithIdentifier:@"att1" URL:[NSURL fileURLWithPath:path] options:nil error:&error];
if (error) {
NSLog(@"%@", error);
}
content.attachments = @[img_attachment];//默认只显示第一个
content.launchImageName = @"launch2";
//消息的处理按钮
UNTextInputNotificationAction *action1 = [UNTextInputNotificationAction actionWithIdentifier:@"replyAction" title:@"回复" options:UNNotificationActionOptionNone];
UNNotificationAction *action2 = [UNNotificationAction actionWithIdentifier:@"enterAction" title:@"进入应用" options:UNNotificationActionOptionForeground];
UNNotificationAction *action3 = [UNNotificationAction actionWithIdentifier:@"cancelAction" title:@"取消" options:UNNotificationActionOptionDestructive];
UNNotificationCategory *categroy = [UNNotificationCategory categoryWithIdentifier:@"CategroyAction" actions:@[action1,action2,action3] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];
[[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:[NSSet setWithObject:categroy]];
content.categoryIdentifier = @"CategroyAction";
//设置推送的触发机制
UNTimeIntervalNotificationTrigger * trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO];
//日历形式，
// NSDateComponents * dateComp = [[NSDateComponents alloc] init];
// dateComp.weekday = 2;//周一,默认第一天是周日
// dateComp.month = 12;//月份，您可以在这里设置具体的时分秒
// dateComp.hour = 10;//小时
// dateComp.minute = 14;//分钟
// UNCalendarNotificationTrigger * calendarTrigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:dateComp repeats:YES];
//地理位置推送.没实际应用过
// CLLocationCoordinate2D location ;
// location.latitude = 123;
// location.longitude = 111;
//
// CLCircularRegion * region = [[CLCircularRegion alloc] initWithCenter:location radius:100.0 identifier:@"regionid"];
//
// UNLocationNotificationTrigger * locationTrigger = [UNLocationNotificationTrigger triggerWithRegion:region repeats:YES];
NSString * identifier = @"notification_onlytextid";
UNNotificationRequest * request = [UNNotificationRequest requestWithIdentifier:identifier content:content trigger:trigger];
[[UNUserNotificationCenter currentNotificationCenter] addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
}];
}
在iOS 10上 我们可以定义对于推送的各种快捷操作，那么我们的如何实现操作方法呢？
答案就是代理，苹果官方的API几乎都是如此！
首先 遵循 代理 <UNUserNotificationCenterDelegate>
实现代理方法,在实际开发中，注意对应的 categoryid
-(void) userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler
{
NSString * categoryid = response.notification.request.content.categoryIdentifier;
NSLog(@"收到通知：%@",response.notification.request.content);
//识别同类类型id
if ([categoryid isEqualToString:@"CategroyAction"])
{
//识别通知操作动作的id
if ([response.actionIdentifier isEqualToString:@"replyAction"])
{
UNTextInputNotificationResponse * textResponse = (UNTextInputNotificationResponse *) response;
NSString * text = textResponse.userText;
//此为输入的内容
}
}
completionHandler();
}
iOS 10上 还有很多操作性的API，修改通知的内容或移除通知等
- identifiers 为我们为本地通知设置的id
//获取所有的未发出的通知，
- (void)getPendingNotificationRequestsWithCompletionHandler:(void(^)(NSArray<UNNotificationRequest *> *requests))completionHandler;
// 移除 identifiers 里面的通知
- (void)removePendingNotificationRequestsWithIdentifiers:(NSArray<NSString *> *)identifiers;
//获取发出的通知
- (void)getDeliveredNotificationsWithCompletionHandler:(void(^)(NSArray<UNNotification *> *notifications))completionHandler __TVOS_PROHIBITED;
// 移除 identifiers 里面 所有的 发出的通知
- (void)removeDeliveredNotificationsWithIdentifiers:(NSArray<NSString *> *)identifiers __TVOS_PROHIBITED;
- (void)removeAllDeliveredNotifications __TVOS_PROHIBITED;
iOS 10以下
UILocalNotification * notification = [[UILocalNotification alloc] init];
notification.alertTitle = @"推送的标题";
notification.alertBody = @"推送的内容";
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];//10s 后
notification.soundName = UILocalNotificationDefaultSoundName;
// [[UIApplication sharedApplication] presentLocalNotificationNow:notification]; 立即触发
[[UIApplication sharedApplication] scheduleLocalNotification:notification];//到设定时间触发
如有瑕疵之处，望大家不吝指教
