iOS 通知扩展插件
目录
-
Notification Content Extension
- 通知内容扩展，是在展示通知时展示一个自定义的用户界面。
-
Notification Service Extension
- 通知服务扩展，是在收到通知后，展示通知前，做一些事情的。比如，增加附件，网络请求等。
Notification Service Extension
- 目前只找到aps推送支持
- 主要是处理一下附件相关的下载
新建一个target
代码实现
@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
// 系统接到通知后，有最多30秒在这里重写通知内容（在此方法可进行一些网络请求，如上报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);
// 添加附件
//1. 下载
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. 保存数据
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. 添加附件
UNNotificationAttachment *attachment = [UNNotificationAttachment attachmentWithIdentifier:@"remote-atta1" URL:[NSURL fileURLWithPath:path] options:nil error:&err];
if (attachment) {
self.bestAttemptContent.attachments = @[attachment];
}
}else{
self.bestAttemptContent.title = @"标题";
self.bestAttemptContent.subtitle = @"子标题";
self.bestAttemptContent.body = @"body";
}
//4. 返回新的通知内容
self.contentHandler(self.bestAttemptContent);
}];
[task resume];
}
// 处理过程超时，则收到的通知直接展示出来
- (void)serviceExtensionTimeWillExpire {
NSLog(@"%s",__FUNCTION__);
self.contentHandler(self.bestAttemptContent);
}
@end
注意事项
- UNNotificationAttachment：attachment 支持
- 音频 5M（kUTTypeWaveformAudio/kUTTypeMP3/kUTTypeMPEG4Audio/kUTTypeAudioInterchangeFileFormat）
- 图片10M（kUTTypeJPEG/kUTTypeGIF/kUTTypePNG）
- 视频50M（kUTTypeMPEG/kUTTypeMPEG2Video/kUTTypeMPEG4/kUTTypeAVIMovie）
UINotificationConentExtension
配置项目
- 新建target，打开推送服务
配置info.plist
- 配置info.plist,和Notification Service Extension进行关联
- 找到这个 UNNotificationExtensionCategory，写到Notification Service Extension中，可以配置多个，对应多个界面
self.bestAttemptContent.categoryIdentifier = @"myNotificationCategory";// 和NotificationConentExtension关联
self.contentHandler(self.bestAttemptContent);
自定义UI
如果我们想要隐藏系统默认的内容页面，也就是下面的那部分，头是隐藏不了的；只需要在Info.plist里添加字段UNNotificationExtensionDefaultContentHidden，bool类型并设置其值为YES；
可以直接修改stroryboard
添加Action，可以添加基本的事件
#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__);
// 添加action
UNNotificationAction * likeAction; //喜欢
UNNotificationAction * ingnoreAction; //取消
UNTextInputNotificationAction * inputAction; //文本输入
likeAction = [UNNotificationAction actionWithIdentifier:@"action_like" title:@"点赞"
options:UNNotificationActionOptionForeground];
inputAction = [UNTextInputNotificationAction actionWithIdentifier:@"action_input"title:@"评论"
options:UNNotificationActionOptionForeground textInputButtonTitle:@"发送"textInputPlaceholder:@"说点什么"];
ingnoreAction = [UNNotificationAction actionWithIdentifier:@"action_cancel"title:@"忽略" options:UNNotificationActionOptionDestructive];
NSString *categoryWithIdentifier = @"myNotificationCategory";// 和info.plist中配置的id一样
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);
// 显示图片
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(@"输入内容：%@",inputAction.userText);
// TODO: 发送评论
completion(UNNotificationContentExtensionResponseOptionDismiss);
} else if ([response.actionIdentifier isEqualToString:@"action_cancel"]) {
completion(UNNotificationContentExtensionResponseOptionDismiss);
} else {
completion(UNNotificationContentExtensionResponseOptionDismiss);
}
completion(UNNotificationContentExtensionResponseOptionDoNotDismiss);
}
