# 为 Unity 设置角标
由于 Unity 插件不包含 PWNotificationExtensionManager 头文件，您必须执行几个额外步骤才能为您的 Unity 项目实现角标。
### 1. 添加 Notification Service Extension (File -> New -> Target...)
### 2. 选择 "Notification Service Extension"
### 3. 将 Pushwoosh.xcframework 添加到 NotificationService 扩展目标，如下所示：
1. 选择 **NotificationService** 扩展目标。
2. 前往 “**General**” 选项卡。
3. 找到 “**Framework and Libraries**” 并按 “**+**” 按钮。
4. 选择 **Pushwoosh.xcframework**。
### 4. 按如下方式更新 Notification Service Extension 代码：
```
#import "NotificationService.h"
#import "PWNotificationExtensionManager.h"
@interface NotificationService ()
@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;
@end
@implementation NotificationService
- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
self.contentHandler = contentHandler;
self.bestAttemptContent = [request.content mutableCopy];
[[PWNotificationExtensionManager sharedManager] handleNotificationRequest:request contentHandler:contentHandler];
}
- (void)serviceExtensionTimeWillExpire {
// Called just before the extension will be terminated by the system.
// Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
self.contentHandler(self.bestAttemptContent);
}
@end
```
### 5. 为您的应用程序的每个目标添加 "App Groups Capability"
### 6. 将 App Groups ID 添加到您应用程序每个目标的 info.plist 中
```
PW_APP_GROUPS_NAME
group.com.example.demoapp_example
```
