iOS10--消息通知的基本使用

官方将通知单独放在了UserNotifications.framework，使用时需要导入框架。
UserNotifications.framework主要类文件：

UNCalendarNotificationTrigger
UNLocationNotificationTrigger
UNMutableNotificationContent
UNNotification
UNNotificationAction
UNNotificationAttachment
UNNotificationCategory
UNNotificationContent
UNNotificationRequest
UNNotificationResponse
UNNotificationServiceExtension
UNNotificationSettings
UNNotificationSound
UNNotificationTrigger
UNPushNotificationTrigger
UNTextInputNotificationAction
UNTextInputNotificationResponse
UNTimeIntervalNotificationTrigger
UNUserNotificationCenter

UNUserNotificationCenter的应用：

请求用户授权：

UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];    
// 请求授权    
/*     
UNAuthorizationOptionBadge   = (1 << 0),     
UNAuthorizationOptionSound   = (1 << 1),     
UNAuthorizationOptionAlert   = (1 << 2),     
UNAuthorizationOptionCarPlay = (1 << 3),     
*/    
[center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {　　if(granted){

if(granded)
//同意
}else{
//不同意
}

}];

补充：获取授权设置信息

// 获取通知授权和设置    
[center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {        
/*         
UNAuthorizationStatusNotDetermined : 没有做出选择         
UNAuthorizationStatusDenied : 用户未授权         
UNAuthorizationStatusAuthorized ：用户已授权         
*/        
if (settings.authorizationStatus == UNAuthorizationStatusNotDetermined) 
{                       
      NSLog(@"未选择");                  
}else if (settings.authorizationStatus == UNAuthorizationStatusDenied){                        
      NSLog(@"未授权");                   
}else if (settings.authorizationStatus == UNAuthorizationStatusAuthorized){                      
      NSLog(@"已授权");        
}       
}]

创建本地通知：

// 创建一个本地通知
UNMutableNotificationContent *content_1 = [[UNMutableNotificationContent alloc] init];    
// 主标题    
content_1.title = [NSString localizedUserNotificationStringForKey:@"title" arguments:nil];    
// 副标题    
content_1.subtitle = [NSString localizedUserNotificationStringForKey:@"subtitle" arguments:nil];    
content_1.badge = [NSNumber numberWithInteger:1];    
content_1.body = [NSString localizedUserNotificationStringForKey:@"title_message_for_yan" arguments:nil];    
content_1.sound = [UNNotificationSound defaultSound];    
// 设置触发时间    
UNTimeIntervalNotificationTrigger *trigger_1 = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:10 repeats:NO];    
// 创建一个发送请求
UNNotificationRequest *request_1 = [UNNotificationRequest requestWithIdentifier:@"my_notification" content:content_1 trigger:trigger_1];

补充：

UserNotifications提供了三种触发器：

UNTimeIntervalNotificationTrigger ：一定时间后触发
 
UNCalendarNotificationTrigger ： 在某月某日某时触发
 
UNLocationNotificationTrigger ： 在用户进入或是离开某个区域时触发

@“my_notification”请求的标识符可以用来管理通知：

- 移除还未展示的通知
[center removePendingNotificationRequestsWithIdentifiers: @[@“my_notification”]];
[center removeAllPendingNotificationRequests]; // - (void)cancelAllLocalNotifications；
 
- 移除已经展示过的通知
[center removeDeliveredNotificationsWithIdentifiers:@[@“my_notification”]];
[center removeAllDeliveredNotifications];
 
- 获取未展示的通知
[center getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) {
    NSLog(@"%@",requests);
}];
 
- 获取展示过的通知
[center getDeliveredNotificationsWithCompletionHandler:^(NSArray<UNNotification *> * _Nonnull notifications) {
    NSLog(@"%@",notifications);
}];

远程通知的格式：

{ "aps":{ "alert":{ "title":"I am title", "subtitle":"I am subtitle", "body":"I am body" }, "sound":"default", "badge":1 } }

具体请参考官方文档

将通知请求添加到通知中心（UNUserNotificationCenter）：

[center addNotificationRequest:request_1 withCompletionHandler:^(NSError * _Nullable error) {

}];

接收通知

处理通知：
设置UNUserNotificationCenterDelegate：
注意：UNUserNotificationCenter 的 delegate 必须在 application:willFinishLaunchingWithOptions: orapplication:didFinishLaunchingWithOptions: 方法中实现；

center.delegate = self;

应用内展示通知:

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
    // 如果不想显示某个通知，可以直接用空 options 调用 completionHandler: // completionHandler([])
    completionHandler(UNNotificationPresentationOptionBadge + UNNotificationPresentationOptionSound);
}

在用户与你推送的通知进行交互时被调用：

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
    completionHandler();
    NSLog(@"userInfo--%@",response.notification.request.content.userInfo);
}

UNNotificationCategory的应用：

创建一个 category：

 
/*
 
UNNotificationActionOptionAuthenticationRequired = (1 << 0),
 
UNNotificationActionOptionDestructive = (1 << 1), 取消
 
UNNotificationActionOptionForeground = (1 << 2), 启动程序
 
*/
 
UNTextInputNotificationAction *textAction = [UNTextInputNotificationAction actionWithIdentifier:@"my_text" title:@"text_action" options:UNNotificationActionOptionForeground textInputButtonTitle:@"输入" textInputPlaceholder:@"默认文字"];
 
UNNotificationAction *action = [UNNotificationAction actionWithIdentifier:@"my_action" title:@"action" options:UNNotificationActionOptionDestructive];
 
UNNotificationAction *action_1 = [UNNotificationAction actionWithIdentifier:@"my_action_1" title:@"action_1" options:UNNotificationActionOptionAuthenticationRequired];
 
/*
 
UNNotificationCategoryOptionNone = (0),
 
UNNotificationCategoryOptionCustomDismissAction = (1 << 0),
 
UNNotificationCategoryOptionAllowInCarPlay = (2 << 0),
 
*/
 
UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"my_category" actions:@[textAction,action,action_1] intentIdentifiers:@[] options:UNNotificationCategoryOptionCustomDismissAction];
 
NSSet *setting = [NSSet setWithObjects:category, nil];
 
[center setNotificationCategories:setting];

在创建 UNNotificationContent 时把 categoryIdentifier 设置为需要的 category id 即可：
```
content.categoryIdentifier = @"my_category";
```
远程推送也可以使用 category，只需要在 payload 中添加 category 字段，并指定预先定义的 category id 就可以了

处理category的通知：

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
 
completionHandler();
 
NSLog(@"userInfo--%@",response.notification.request.content.userInfo);
 
// 获取通知中心的所有的Categories
 
[center getNotificationCategoriesWithCompletionHandler:^(NSSet<UNNotificationCategory *> * _Nonnull categories) {
 
for (UNNotificationCategory *category in categories) {
 
if ([category.identifier isEqualToString:@"my_category"] && [response.notification.request.content.categoryIdentifier isEqualToString:@"my_category"]) {
 
for (UNNotificationAction *textAction in category.actions) {
 
if ([textAction.identifier isEqualToString:@"my_text"]) {
 
UNTextInputNotificationAction *text = (UNTextInputNotificationAction *)textAction;
 
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:text.textInputButtonTitle preferredStyle:UIAlertControllerStyleAlert];
 
[alert addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleCancel handler:nil]];
 
[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:alert animated:YES completion:nil];
 
}
 
}
 
}
 
}
 
}];
 
}
