iOS 10 如何使用UNUserNotificationCenter查看待处理通知列表?
iOS 10 How to view a list of pending notifications using UNUserNotificationCenter?
解决方案代码:
let center = UNUserNotificationCenter.current()
print(center.getPendingNotificationRequests(completionHandler: { error in
// error handling here
}))
我原来的post:
我正在尝试通过 UNUserNotificationCenter 获取待处理通知列表,因为 UIApplication.shared.scheduledLocalNotifications
已贬值。
这是我正在使用的代码:
let center = UNUserNotificationCenter.current()
print(UNUserNotificationCenter.getPendingNotificationRequests(center))
但是这会打印“(函数)”。 getPendingNotificationRequests 需要一个 UNUserNotificationCenter 参数,我想不出它还能是什么。
谢谢
getPendingNotificationRequests
调用将一组请求传递给完成闭包。尝试这样的事情:
let center = UNUserNotificationCenter.current()
center.getPendingNotificationRequests(completionHandler: { requests in
for request in requests {
print(request)
}
})
现在还没有,但你应该允许使用通知
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
if !granted {
print("user has declined notifications")
}
}
以防万一有人需要访问已发送的通知(用户可以在通知中心看到它们),可以通过以下方式完成:
let center = UNUserNotificationCenter.current()
center.getDeliveredNotifications { notifications in
// use center.removeDeliveredNotifications(withIdentifiers:requestIdsToRemove)
// if you want to cancel some of the notifications displayed to user
}
}
对于 ObjC:-
[[UNUserNotificationCenter currentNotificationCenter] getPendingNotificationRequestsWithCompletionHandler:^(NSArray *requests){
NSLog(@"请求: %@", 请求);
}];

let center = UNUserNotificationCenter.current()
print(center.getPendingNotificationRequests(completionHandler: { error in
// error handling here
