Question

我们如何显示图像或任何带有本地通知的附件，就像我们以前在丰富通知中显示的那样？

我正在接收静默通知，然后在本地通知中对其进行更改。

Answer 1

是的，您也可以在本地通知中显示它，您必须在收到静默推送后触发本地通知，我希望在平稳的通知有效负载中所有需要数据的地方都存在。

这是代码段

let content = UNMutableNotificationContent()

//Configure notification 

content.title = "Notification Title"
content.body = "Notification Body"
content.sound = UNNotificationSound.default()  
content.categoryIdentifier = "ImageNotification"


//Attach your image local path here (Document dir path)

let attachment = try! UNNotificationAttachment(identifier: "\(NSDate().timeIntervalSince1970 * 1000)", url: localURL, options: [:])
content.attachments = [attachment]


content.userInfo = ["attachmentType": "Media"]

// Create a trigger for fire a local notification

let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 0.2, repeats: false)        
let request = UNNotificationRequest(identifier: "\(NSDate().timeIntervalSince1970 * 1000)", content: content, trigger: trigger)

// Configure according to version

if #available(iOS 11.0, *) {
let contactCategory = UNNotificationCategory(identifier: content.categoryIdentifier,
                                                         actions: [],
                                                         intentIdentifiers: [],
                                                         hiddenPreviewsBodyPlaceholder: "",
                                                         options: .customDismissAction)
let notificationCenter = UNUserNotificationCenter.current()
            notificationCenter.setNotificationCategories([contactCategory])
} else {
        // Fallback on earlier versions

let contactCategory = UNNotificationCategory(identifier: content.categoryIdentifier, actions: [], intentIdentifiers: [], options: [])
            let notificationCenter = UNUserNotificationCenter.current()
            notificationCenter.setNotificationCategories([contactCategory])
        }


UNUserNotificationCenter.current().add(request) {[weak self] (error) in
    guard error == nil else { 
                return
    }
}

此工具实施后可以正常工作，如果您仍然遇到任何问题，请告诉我。
