背景
iOS 10之前,iPhone手机中,通知栏仅能展示 标题和内容文本
iOS 10 开始,苹果新增了UserNotifications.framework库用于对通知的扩展。通过UNNotificationService 与 UNNotificationContent来进行通知的 拦截 与 通知界面的自定义。让通知栏变得丰富多彩,既可以展示图文内容,也可以展示音视频。使得用户在不打开App的情况下也能进行App内容的交互。
iOS 12开始,新增了通知栏的分组,默认会根据Bundle Id自动区分不同应用的通知,也可以通过Thread identifier 精细化控制同一个应用里不同类型的通知。
自动:按照Thread identifier进行区分不同的消息,App如果未设置Thread identifier,则按照Bundle Id区分。
按App:按照App的 Bundle Id 区分通知消息
关:关闭App的通知分组
UNNotificationServiceExtension 与 UNNotificationContentExtension的关系
UNNotificationServiceExtension负责拦截通知,对通知内容做中间处理,而UNNotificationContentExtension负责自定义通知界面的。
如果只是想对通知内容进行解析或单纯的系统通知中有小图片,那么使用UNNotificationServiceExtension即可
如果想显示用户长按通知自定义后显示的通知界面,则需要使用UNNotificationContentExtension自定义通知界面
一般都是UNNotificationServiceExtension与UNNotificationContentExtension结合使用,由UNNotificationServiceExtension解密通知,将通知内容进行转换,并下载相关的通知资源文件。然后在UNNotificationContentExtension中拿到UNNotificationServiceExtension处理后的通知内容,将内容赋值在界面上进行展示。
UNNotificationServiceExtension
苹果官方关于UNNotificationServiceExtension的说明文档
UNNotificationServiceExtension是用于拦截远程通知的,在手机收到对应App的通知时,会触发UNNotificationServiceExtension,可以在UNNotificationServiceExtension中对通知内容进行修改,收到可以对通知添加附件,例如图片、音频、视频。
1、创建UNNotificationServiceExtension
在工程中的TARGETS中选择加号,然后在 iOS 模板中选择 Notification Service Extension
NotificationService是通知拦截响应的类,Info.plist是NotificationsServiceExtension的配置信息。
在NotificationService.m中,自动生成了contentHandler与bestAttemptContent两个属性。didReceiveNotificationRequest:withContentHandler与serviceExtensionTimeWillExpire方法。
bestAttemptContent
//通知消息的内容对象,里面包含了通知相关的所有信息。一般有title、body、subTitle。
//如果是服务端封装的扩展参数,则一般都在userInfo中。
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;
contentHandler
//用于告知系统已经处理完成,可以将通知内容传给App的回调对象。
//该对象需要返回一个UNMutableNotificationContent对象。一般都是返回bestAttemptContent
@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
didReceiveNotificationRequest:withContentHandler
//可以通过重写此方法来实现自定义推送通知修改。
//如果要使用修改后的通知内容,则需要在该方法中调用contentHandler传递修改后的通知内容。
//如果在服务时间(30秒)到期之前未调用处理程序contentHandler,则将传递未修改的通知。
//@param request 通知内容
//@param contentHandler 处理结果,需要返回一个UNNotificationContent的通知内容
- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
//接收回调对象
self.contentHandler = contentHandler;
//copy通知内容
self.bestAttemptContent = [request.content mutableCopy];
//回调通知结果
self.contentHandler(self.bestAttemptContent);
}
serviceExtensionTimeWillExpire
//当didReceiveNotificationRequest的方法执行超过30秒未调用contentHandler时
//系统会自动调用serviceExtensionTimeWillExpire方法,给我们最后一次弥补处理的机会
//可以在serviceExtensionTimeWillExpire方法中设置didReceiveNotificationRequest方法中未完成数据的默认值
- (void)serviceExtensionTimeWillExpire {
self.contentHandler(self.bestAttemptContent);
}
UNNotificationRequest
远程通知发送给App的通知请求,其中包括通知的内容和交互的触发条件。
@interface UNNotificationRequest : NSObject
// 该属性为通知请求的唯一标识符。可以用它来替换或删除挂起的通知请求或已传递的通知。
@property (NS_NONATOMIC_IOSONLY, readonly, copy) NSString *identifier;
// 该属性是用于显示的通知内容
@property (NS_NONATOMIC_IOSONLY, readonly, copy) UNNotificationContent *content;

@property (NS_NONATOMIC_IOSONLY, readonly, copy, nullable) UNNotificationTrigger *trigger;
UNNotificationTrigger
抽象类,用于表示触发通知传递的事件。不能直接创建此类的实例。具体的触发子类看下面的类

UNNotificationContent
通知的具体内容,包括通知类型、自定义参数、附件信息等。不能直接创建该类,如果需要创建自定义的通知内容,应该创建UNMutableNotificationContent,并配置内容
// 附件数组,必须是UNNotificationAttachment对象
@property (NS_NONATOMIC_IOSONLY, readonly, copy) NSArray *attachments API_UNAVAILABLE(tvos);

UNNotificationSound
通知发出时,通知的声音。如果想手机收到通知时播放特定声音,需要创建UNNotificationSound对象来设置特定的音频文件。UNNotificationSound对象仅读取以下位置文件:
应用程序容器目录的/Library/Sounds目录。
应用程序的共享组容器目录之一的/Library/Sounds目录。播放自定义声音,必须采用以下音频数据格式之一:Linear PCM、MA4 (IMA/ADPCM)、µLaw、aLaw
可以将音频数据打包为aiff、wav或caf文件。声音文件的长度必须小于30秒。如果声音文件超过30秒,系统将播放默认声音
可以使用afconvert命令行工具转换声音。例如,将系统声音转换为Submarine.aiff。aiff到IMA4音频在CAF文件中,在终端中使用以下命令:
afconvert /System/Library/Sounds/Submarine.aiff ~/Desktop/sub.caf -d ima4 -f caff -

UNNotificationAttachment
通知的附件,可以存放音频、图像或视频内容,创建UNNotificationAttachment对象时,指定的文件必须在磁盘上,并且文件格式必须是受支持的类型之一。不然会创建失败,返回nil。
系统会在显示相关通知之前验证附件。如果是本地通知,请求附加的文件已损坏、无效或文件类型不受支持,则系统不会执行请求。如果是远程通知,系统会在通知服务应用程序扩展完成后验证附件。验证后,系统会将附件移动到附件数据存储中,以便适当的流程可以访问这些文件。系统会复制应用包中的附件。
附件类型 | 支持的文件类型 | 文件的最大容量 |

UNNotificationContentExtension
该扩展是为应用创建自定义的通知界面的。可以在UIViewController里设置界面,在didReceiveNotification方法中获得通知数据赋值界面。
UNNotificationContentExtension 的info.plist配置参数说明
key | value |
---|---|
UNNotificationExtensionCategory(必填) | string值或Array值,自定义通知界面的标识符,系统会根据通知中category 的名称自动与该值匹配,匹配后会使用该自定义界面。设置为string则表示只有一个,设置为Array则表示有多个 |
UNNotificationExtensionInitialContentSizeRatio(必填) | 浮点值,表示视图控制器视图的初始大小,表示为其高度与宽度的比率。加载自定义通知视图时,系统使用此值设置视图控制器的初始大小,以宽度为基数。例如,值为0.5时,表示 高度 = 宽度 * 0.5。值为2,表示 高度 = 宽度 * 2 |
UNNotificationExtensionDefaultContentHidden | BOOL值,表示打开自定义通知界面的时候,是否隐藏默认通知的导航标题和内容,设置为YES时只显示自定义的内容,默认为NO |
UNNotificationExtensionOverridesDefaultTitle | BOOL值,设置为YES时,系统将使用视图控制器的title属性作为通知的标题。设置为NO时,系统会将通知的标题设置为应用程序的名称。默认为NO |
NSExtensionMainStoryboard | 自定义界面对应的SB文件名 |
NSExtensionPointIdentifier | 是扩展的唯一标识,设置为com.apple.usernotifications.content-extension后会被系统识别为苹果通知的Content的扩展 |
UNNotificationExtensionUserInteractionEnabledYES | BOOL类型,设置为YES后,自定义界面运行有交互行为,设置为NO的话点击自定义界面会直接打开App |

注意:因为UNNotificationServiceExtension与UNNotificationContentExtension是两个不同的target,沙盒路径不同。一般都是在UNNotificationServiceExtension中下载附件资源并保存在UNNotificationServiceExtension的沙盒路径,然后在UNNotificationContentExtension中接收附件的路径。因此要访问UNNotificationServiceExtension的路径需要使用startAccessingSecurityScopedResource与stopAccessingSecurityScopedResource
/* 例 */
- (void)didReceiveNotification:(UNNotification *)notification {
if (notification.request.content.attachments && notification.request.content.attachments.count > 0) {
UNNotificationAttachment *attachment = [notification.request.content.attachments firstObject];
//通过使用安全作用域解析创建的attachment数据而创建的NSURL,使url引用的资源可供进程访问。
//startAccessingSecurityScopedResource与stopAccessingSecurityScopedResource需成对出现
//当不再需要访问此资源时,客户端必须调用stopAccessingSecurityScopedResource
if ([attachment.URL startAccessingSecurityScopedResource]) {
NSData *imageData = [NSData dataWithContentsOfURL:attachment.URL];
self.imageView.image = [UIImage imageWithData:imageData];
[attachment.URL stopAccessingSecurityScopedResource];
}
}
}
UNNotificationAction
使用UNNotificationAction对象,可以定义在响应已发送通知时可以执行的操作。例如,会议App可能会定义会议邀请的接受或拒绝的操作,就可以用UNNotificationAction来设置接受和拒绝的按钮,直接在通知界面完成操作,而不用打开App进行操作,UNNotificationAction最多设置4个。
