iOS 通知擴充套件外掛

iOS 通知擴充套件外掛

  • Notification Content Extension

    • 通知內容擴充套件,是在展示通知時展示一個自定義的使用者介面。
  • Notification Service Extension

    • 通知服務擴充套件,是在收到通知後,展示通知前,做一些事情的。比如,增加附件,網路請求等。

Notification Service Extension

  • 目前只找到aps推送支援
  • 主要是處理一下附件相關的下載

新建一個target

  • 老的xcode版本開啟VoIP功能也是在 Background Modes 中直接勾選就開啟了,但是新版的xcode移除了這個選項,所以只能在 info.plist 檔案中去手動新增
  • 參考1
  • 參考2

程式碼實現

@interface NotificationService : UNNotificationServiceExtension

@end

#import "NotificationService.h"
#import <UIKit/UIKit.h>

@interface NotificationService ()

@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;

@end

@implementation NotificationService
// 系統接到通知後,有最多30秒在這裡重寫通知內容(在此方法可進行一些網路請求,如上報是否收到通知等操作)
- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
     NSLog(@"%s",__FUNCTION__);
    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];
    
    // Modify the notification content here...
    NSLog(@"%@",request.content);
    // 新增附件
    //1. 下載
    NSURL *url = [NSURL URLWithString:@"https://tva1.sinaimg.cn/large/008i3skNgy1gtir9lwnj0j61x40gsabl02.jpg"];
    NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
    NSURLSessionDataTask *task = [session dataTaskWithURL:url completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        
        if (!error) {
            //2. 儲存資料
            NSString *path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES).firstObject
                              stringByAppendingPathComponent:@"download/image.jpg"];
            UIImage *image = [UIImage imageWithData:data];
            NSError *err = nil;
            [UIImageJPEGRepresentation(image, 1) writeToFile:path options:NSAtomicWrite error:&err];
            //3. 新增附件
            UNNotificationAttachment *attachment = [UNNotificationAttachment attachmentWithIdentifier:@"remote-atta1" URL:[NSURL fileURLWithPath:path] options:nil error:&err];
            if (attachment) {
                self.bestAttemptContent.attachments = @[attachment];
            }
        }else{
            self.bestAttemptContent.title = @"標題";
                self.bestAttemptContent.subtitle = @"子標題";
                self.bestAttemptContent.body = @"body";
        }
        //4. 返回新的通知內容
        self.contentHandler(self.bestAttemptContent);
    }];
    [task resume];
}
// 處理過程超時,則收到的通知直接展示出來
- (void)serviceExtensionTimeWillExpire {
    NSLog(@"%s",__FUNCTION__);
    self.contentHandler(self.bestAttemptContent);
}

@end

注意事項

  • UNNotificationAttachment:attachment 支援
    • 音訊 5M(kUTTypeWaveformAudio/kUTTypeMP3/kUTTypeMPEG4Audio/kUTTypeAudioInterchangeFileFormat)
    • 圖片10M(kUTTypeJPEG/kUTTypeGIF/kUTTypePNG)
    • 視訊50M(kUTTypeMPEG/kUTTypeMPEG2Video/kUTTypeMPEG4/kUTTypeAVIMovie)

UINotificationConentExtension

配置專案

  • 新建target,開啟推送服務

配置info.plist

  • 配置info.plist,和Notification Service Extension進行關聯

  • 找到這個 UNNotificationExtensionCategory,寫到Notification Service Extension中,可以配置多個,對應多個介面
   self.bestAttemptContent.categoryIdentifier = @"myNotificationCategory";// 和NotificationConentExtension關聯
    self.contentHandler(self.bestAttemptContent);

自定義UI

  • 如果我們想要隱藏系統預設的內容頁面,也就是下面的那部分,頭是隱藏不了的;只需要在Info.plist裡新增欄位UNNotificationExtensionDefaultContentHidden,bool型別並設定其值為YES;

  • 可以直接修改stroryboard

  • 新增Action,可以新增基本的事件


#import "NotificationViewController.h"
#import <UserNotifications/UserNotifications.h>
#import <UserNotificationsUI/UserNotificationsUI.h>

@interface NotificationViewController () <UNNotificationContentExtension,UIActionSheetDelegate>

@property IBOutlet UILabel *label;
@property (weak, nonatomic) IBOutlet UIImageView *imageView;

@end

@implementation NotificationViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"%s",__FUNCTION__);
     // 新增action
    UNNotificationAction * likeAction;              //喜歡
    UNNotificationAction * ingnoreAction;           //取消
    UNTextInputNotificationAction * inputAction;    //文字輸入
    
    likeAction = [UNNotificationAction actionWithIdentifier:@"action_like" title:@"點贊"
options:UNNotificationActionOptionForeground];
    inputAction = [UNTextInputNotificationAction actionWithIdentifier:@"action_input"title:@"評論"
options:UNNotificationActionOptionForeground                                                 textInputButtonTitle:@"傳送"textInputPlaceholder:@"說點什麼"];
ingnoreAction = [UNNotificationAction actionWithIdentifier:@"action_cancel"title:@"忽略" options:UNNotificationActionOptionDestructive];
    NSString *categoryWithIdentifier = @"myNotificationCategory";// 和info.plist中配置的id一樣
    UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:categoryWithIdentifier actions:@[likeAction,inputAction,ingnoreAction] intentIdentifiers:@[] options:UNNotificationCategoryOptionNone];
    
    NSSet *sets = [NSSet setWithObjects:category,nil];
    [[UNUserNotificationCenter currentNotificationCenter] setNotificationCategories:sets];
}

- (void)didReceiveNotification:(UNNotification *)notification {
    self.label.text = notification.request.content.body;
    NSLog(@"didReceiveNotification:%@",notification.request.content);
    for (UNNotificationAttachment * attachment in notification.request.content.attachments) {
        NSLog(@"url:%@",attachment.URL);
        // 顯示圖片
        if([attachment.URL startAccessingSecurityScopedResource]){
            NSData *data = [NSData dataWithContentsOfURL:attachment.URL];
            self.imageView.image = [UIImage imageWithData:data];
            [attachment.URL stopAccessingSecurityScopedResource];
        }
    
    }
}

- (void)didReceiveNotificationResponse:(UNNotificationResponse *)response completionHandler:(void (^)(UNNotificationContentExtensionResponseOption))completion {
    NSLog(@"response:%@",response);
    if ([response.actionIdentifier isEqualToString:@"action_like"]) {
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            completion(UNNotificationContentExtensionResponseOptionDismiss);
        });
    } else if ([response.actionIdentifier isEqualToString:@"action_input"]) {
        UNTextInputNotificationResponse *inputAction = (UNTextInputNotificationResponse*)response;
        NSLog(@"輸入內容:%@",inputAction.userText);
        // TODO: 傳送評論
        completion(UNNotificationContentExtensionResponseOptionDismiss);
    } else if ([response.actionIdentifier isEqualToString:@"action_cancel"]) {
        completion(UNNotificationContentExtensionResponseOptionDismiss);
    } else {
        completion(UNNotificationContentExtensionResponseOptionDismiss);
    }
    completion(UNNotificationContentExtensionResponseOptionDoNotDismiss);
}
