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 之前的通知栏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。
图文推送长按推送推送后带有图文的自定义推送长按推送后带有交互的自定义推送长按推送后的带有聊天回复功能的自定义推送
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。
设置App分组
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;

@property (NS_NONATOMIC_IOSONLY, readonly, copy) UNNotificationContent *content;

@property (NS_NONATOMIC_IOSONLY, readonly, copy, nullable) UNNotificationTrigger *trigger;
UNNotificationTrigger

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。
