`getPendingNotificationRequestsWithCompletionHandler:`是 iOS 用户通知框架类中的一个方法`UNUserNotificationCenter`。它允许您检索任何已安排但尚未交付的待处理通知请求。
### 用法
使用此方法的方法如下:
1. **导入用户通知框架**
确保在文件顶部导入框架:
``` objc
@import UserNotifications;
```
**请求待处理通知**
2. 您可以调用此方法来获取待处理的通知请求数组:
``` objc
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center getPendingNotificationRequestsWithCompletionHandler:^(NSArray<UNNotificationRequest *> * _Nonnull requests) {
for (UNNotificationRequest *request in requests) {
NSLog(@"Pending notification: %@", request.content.title);
// You can also access other properties of the request
}
}];
```
### 笔记
- 完成处理程序提供了一个对象数组`UNNotificationRequest`,每个对象代表一个计划的通知。
- 您可以使用此方法在通知发送之前管理或修改通知,或者只是检查哪些通知处于待处理状态。
