第一步: 导入 #import
且要遵守
这里需要注意,我们最好写成这种形式(防止低版本找不到头文件出现问题)
#ifdef NSFoundationVersionNumber_iOS_9_x_Max
#import
#endif
第二步:我们需要在
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中注册通知,代码如下
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self replyPushNotificationAuthorization:application];
return YES; }
#pragma mark - 申请通知权限// 申请通知权限
- (void)replyPushNotificationAuthorization:(UIApplication *)application{
if (IOS10_OR_LATER) {
//iOS 10 later
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
//必须写代理,不然无法监听通知的接收与点击事件
center.delegate = self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!error && granted) {
//用户点击允许
NSLog(@"注册成功");
}else{
//用户点击不允许
NSLog(@"注册失败");
}
}];
// 可以通过 getNotificationSettingsWithCompletionHandler 获取权限设置
//之前注册推送服务,用户点击了同意还是不同意,以及用户之后又做了怎样的更改我们都无从得知,现在 apple 开放了这个 API,我们可以直接获取到用户的设定信息了。注意UNNotificationSettings是只读对象哦,不能直接修改!
[center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) { NSLog(@"========%@",settings);
}];
}else if (IOS8_OR_LATER){
//iOS 8 - iOS 10系统
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
[application registerUserNotificationSettings:settings];
}else{
//iOS 8.0系统以下
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];
}
//注册远端消息通知获取device token
[application registerForRemoteNotifications];
}
上面需要注意:
之前注册推送服务,用户点击了同意还是不同意,以及用户之后又做了怎样的更改我们都无从得知,现在 apple 开放了这个 API,我们可以直接获取到用户的设定信息了。注意UNNotificationSettings是只读对象哦,不能直接修改!只能通过以下方式获取
[center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
NSLog(@"========%@",settings);
}];
打印信息如下: ========
4、 远端推送需要获取设备的Device Token的方法是没有变的,代码如下
#pragma mark - 获取device Token//获取DeviceToken成功
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{ //解析NSData获取字符串
//我看网上这部分直接使用下面方法转换为string,你会得到一个nil(别怪我不告诉你哦)
//错误写法
//NSString *string = [[NSString alloc] initWithData:deviceToken encoding:NSUTF8StringEncoding];
//正确写法
NSString *deviceString = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
deviceString = [deviceString stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"deviceToken===========%@",deviceString); }
//获取DeviceToken失败
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{ NSLog(@"[DeviceToken Error]:%@\n",error.description);
}
5、这一步吊了,这是iOS 10系统更新时,苹果给了我们2个代理方法来处理通知的接收和点击事件,这两个方法在
此外,苹果把本地通知跟远程通知合二为一。区分本地通知跟远程通知的类是
UNPushNotificationTrigger.h类中,
UNPushNotificationTrigger的类型是新增加的,通过它,我们可以得到一些通知的触发条件 ,解释如下:
UNPushNotificationTrigger (远程通知) 远程推送的通知类型
UNTimeIntervalNotificationTrigger (本地通知) 一定时间之后,重复或者不重复推送通知。我们可以设置timeInterval(时间间隔)和repeats(是否重复)。
UNCalendarNotificationTrigger(本地通知) 一定日期之后,重复或者不重复推送通知 例如,你每天8点推送一个通知,只要dateComponents为8,如果你想每天8点都推送这个通知,只要repeats为YES就可以了。
UNLocationNotificationTrigger (本地通知)地理位置的一种通知,
当用户进入或离开一个地理区域来通知。现在先提出来,后面我会一一代码演示出每种用法。还是回到两个很吊的代理方法吧
#pragma mark - iOS10 收到通知(本地和远端) UNUserNotificationCenterDelegate
//App处于前台接收通知时
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
//收到推送的请求
UNNotificationRequest *request = notification.request;
//收到推送的内容
UNNotificationContent *content = request.content;
//收到用户的基本信息
NSDictionary *userInfo = content.userInfo;
//收到推送消息的角标
NSNumber *badge = content.badge;
//收到推送消息body
NSString *body = content.body;
//推送消息的声音
UNNotificationSound *sound = content.sound;
// 推送消息的副标题
NSString *subtitle = content.subtitle;
// 推送消息的标题
NSString *title = content.title;
if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) { //此处省略一万行需求代码。。。。。。
NSLog(@"iOS10 收到远程通知:%@",userInfo);
}else {
// 判断为本地通知
//此处省略一万行需求代码。。。。。。
NSLog(@"iOS10 收到本地通知:{\\\\nbody:%@,\\\\ntitle:%@,\\\\nsubtitle:%@,\\\\nbadge:%@,\\\\nsound:%@,\\\\nuserInfo:%@\\\\n}",body,title,subtitle,badge,sound,userInfo);
}
// 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 completionHandler(UNNotificationPresentationOptionBadge|
UNNotificationPresentationOptionSound|
UNNotificationPresentationOptionAlert);
}
//App通知的点击事件
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
//收到推送的请求
UNNotificationRequest *request = response.notification.request;
//收到推送的内容
UNNotificationContent *content = request.content;
//收到用户的基本信息
NSDictionary *userInfo = content.userInfo;
//收到推送消息的角标
NSNumber *badge = content.badge;
//收到推送消息body
NSString *body = content.body;
//推送消息的声音
UNNotificationSound *sound = content.sound;
// 推送消息的副标题
NSString *subtitle = content.subtitle;
// 推送消息的标题
NSString *title = content.title;
if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
NSLog(@"iOS10 收到远程通知:%@",userInfo);
//此处省略一万行需求代码。。。。。。
}else {
// 判断为本地通知
//此处省略一万行需求代码。。。。。。
NSLog(@"iOS10 收到本地通知:{\\\\nbody:%@,\\\\ntitle:%@,\\\\nsubtitle:%@,\\\\nbadge:%@,\\\\nsound:%@,\\\\nuserInfo:%@\\\\n}",body,title,subtitle,badge,sound,userInfo);
}

completionHandler(); // 系统要求执行这个方法
}
需要注意的:
1.下面这个代理方法,只会是app处于前台状态 前台状态 and 前台状态下才会走,后台模式下是不会走这里的 - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
2.下面这个代理方法,只会是用户点击消息才会触发,如果使用户长按(3DTouch)、Action等并不会触发。
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
3.点击代理最后需要执行:completionHandler(); // 系统要求执行这个方法
不然会报:

4.不管前台后台状态下。推送消息的横幅都可以展示出来!后台状态不用说,前台时需要在前台代理方法中设置 ,设置如下:
// 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
completionHandler(UNNotificationPresentationOptionBadge|
UNNotificationPresentationOptionSound|
UNNotificationPresentationOptionAlert);
