#iOS 10 通知之本地通知
本地通知顾名思义就是本地推送到本地，类似于闹钟，事件提醒等。在iOS 10 后，本地通知可以通过UserNotifications/UserNotifications.h 框架 进行操作。
实现步骤：
1、基本操作
-
导入UserNotifications/UserNotifications.h 库
最好这样写：
#ifdef NSFoundationVersionNumber_iOS_9_x_Max #import <UserNotifications/UserNotifications.h> #endif -
遵守的协议。
-
在Appdelegate.m 中 注册通知中心 在
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中注册通知：
if ([[UIDevice currentDevice].systemVersion floatValue] >= 10.0) {
// iOS 10 特有
// 1、创建一个 UNUserNotificationCenter
UNUserNotificationCenter *requestCenter = [UNUserNotificationCenter currentNotificationCenter];
// 必须写代理，不然无法监听通知的接收与点击
requestCenter.delegate = self;
[requestCenter requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionSound) completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted) {
// 点击允许
NSLog(@"注册成功");
[requestCenter getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
NSLog(@"%@",settings);
}];
}else {
// 点击不允许
NSLog(@"注册失败");
}
}];
} else if ([[UIDevice currentDevice].systemVersion floatValue] > 8.0) {
// iOS 8 ~iOS 10
[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]];
} else if ([[UIDevice currentDevice].systemVersion floatValue] < 8.0) {
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];
}
// 注册获得device Token
[[UIApplication sharedApplication] registerForRemoteNotifications];
2、两个回调方法
// iOS 10收到通知
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler {
NSDictionary *userInfo = notification.request.content.userInfo;
UNNotificationRequest *request = notification.request; // 收到推送的请求
UNNotificationContent *content = request.content; // 收到推送的消息内容
NSNumber *badge = content.badge; // 推送消息的角标
NSString *body = content.body; // 推送消息体
UNNotificationSound *sound = content.sound; // 推送消息的声音
NSString *subString = content.subtitle; // 推送消息的副标题
NSString *title = content.title; // 推送消息的标题
if ([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
NSLog(@"iOS10 前台收到本地通知：");
} else {
// 判断为本地通知
NSLog(@"iOS 10 收到本地通知：{\nbody:%@,\ntitle:%@,\nsubtitle:%@,\nbadge:%@,\nsound:%@,\nuserInfo:%@\n}",body,title,subString,badge,sound,userInfo);
}
// Warning: UNUserNotificationCenter delegate received call to -userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler: but the completion handler was never called.
completionHandler(UNNotificationPresentationOptionBadge|UNNotificationPresentationOptionSound|UNNotificationPresentationOptionAlert); // 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
}
// 通知的点击事件
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
// 通知图标减少一
[UIApplication sharedApplication].applicationIconBadgeNumber --;
NSDictionary * userInfo = response.notification.request.content.userInfo;
UNNotificationRequest *request = response.notification.request; // 收到推送的请求
UNNotificationContent *content = request.content; // 收到推送的消息内容
NSNumber *badge = content.badge; // 推送消息的角标
NSString *body = content.body; // 推送消息体
UNNotificationSound *sound = content.sound; // 推送消息的声音
NSString *subtitle = content.subtitle; // 推送消息的副标题
NSString *title = content.title; // 推送消息的标题
if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
NSLog(@"iOS10 收到远程通知:");
}
else {
// 判断为本地通知
NSLog(@"iOS10 收到本地通知:{\\\\nbody:%@，\\\\ntitle:%@,\\\\nsubtitle:%@,\\\\nbadge：%@，\\\\nsound：%@，\\\\nuserInfo：%@\\\\n}",body,title,subtitle,badge,sound,userInfo);
}
// Warning: UNUserNotificationCenter delegate received call to -userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler: but the completion handler was never called.
completionHandler(); // 系统要求执行这个方法
}
其他版本的接收通知的回调方法
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {
// NSLog(@"iOS6及以下系统，收到通知:%@", [self logDic:userInfo]);
}
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:
(void (^)(UIBackgroundFetchResult))completionHandler {
// NSLog(@"iOS7及以上系统，收到通知:%@", [self logDic:userInfo]);
completionHandler(UIBackgroundFetchResultNewData);
}
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
//通知的图标减少方法一： 单例 减少
[UIApplication sharedApplication].applicationIconBadgeNumber --;
//减少方法二：
// application.applicationIconBadgeNumber--;
// 视图推送到
}
3、在需要设置本地通知的地方设置
// 1、创建通知内容
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.title = @"本地通知测试";
content.subtitle = @"测试通知";
content.body = @"来自ZHZ的CSDN";
// 设置消息提醒的数目
NSInteger count = [UIApplication sharedApplication].applicationIconBadgeNumber+1;
content.badge = [NSNumber numberWithInteger:count];
NSError *error = nil;
NSString *path = [[NSBundle mainBundle] pathForResource:@"1" ofType:@"jpg"];
// 2、设置通知附件内容
UNNotificationAttachment *att = [UNNotificationAttachment attachmentWithIdentifier:@"att1" URL:[NSURL fileURLWithPath:path] options:nil error:&error];
if (error) {
NSLog(@"attachment error %@",error);
}
content.attachments = @[att];
content.launchImageName = @"1";
// 2、设置声音
UNNotificationSound *sound = [UNNotificationSound defaultSound];
content.sound = sound;
// 3、触发模式
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:5 repeats:NO];
// 4、设置UNNotificationRequest
NSString *requestIdentifier = @"TestRequest";
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:requestIdentifier content:content trigger:trigger];
// 5、把通知加到UNUserNotificationCenter，到指定触发点会被触发
[[UNUserNotificationCenter currentNotificationCenter] addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
NSLog(@"通知");
}];
