摘要:iOS 8提供了一个令人兴奋的新API来创建交互式通知,它能让你在你的应用之外为用户提供额外的功能。
由于发现网上还没有关于如何实现它的比较好的示例教程,所以我将在这篇文章里来实现一个简单的交互式通知示例,分享给大家。
和以前简单地注册通知类型(sounds、banners、alerts)相比,现在你可以注册自定义的通知类别和动作。类别描述了应用自定义的通知类型,并且包含用户能够执行的响应动作。比如,你收到一个通知说某人在社交网上了关注了你,作为回应你可能会想要关注他或者忽略。
这里是一个非常简单的使用Objective-C编写的示例,演示如何注册一个包含两个动作的通知。
01 |
NSString * const NotificationCategoryIdent = @ "ACTIONABLE" ; |
02 |
NSString * const NotificationActionOneIdent = @ "ACTION_ONE" ; |
03 |
NSString * const NotificationActionTwoIdent = @ "ACTION_TWO" ; |
04 |
- ( void )registerForNotification { |
05 |
UIMutableUserNotificationAction *action1; |
06 |
action1 = [[UIMutableUserNotificationAction alloc] init]; |
07 |
[action1 setActivationMode:UIUserNotificationActivationModeBackground]; |
08 |
[action1 setTitle:@ "Action 1" ]; |
09 |
[action1 setIdentifier:NotificationActionOneIdent]; |
10 |
[action1 setDestructive:NO]; |
11 |
[action1 setAuthenticationRequired:NO]; |
12 |
UIMutableUserNotificationAction *action2; |
13 |
action2 = [[UIMutableUserNotificationAction alloc] init]; |
14 |
[action2 setActivationMode:UIUserNotificationActivationModeBackground]; |
15 |
[action2 setTitle:@ "Action 2" ]; |
16 |
[action2 setIdentifier:NotificationActionTwoIdent]; |
17 |
[action2 setDestructive:NO]; |
18 |
[action2 setAuthenticationRequired:NO]; |
19 |
UIMutableUserNotificationCategory *actionCategory; |
20 |
actionCategory = [[UIMutableUserNotificationCategory alloc] init]; |
21 |
[actionCategory setIdentifier:NotificationCategoryIdent]; |
22 |
[actionCategory setActions:@[action1, action2] |
23 |
forContext:UIUserNotificationActionContextDefault]; |
24 |
NSSet *categories = [NSSet setWithObject:actionCategory]; |
25 |
UIUserNotificationType types = (UIUserNotificationTypeAlert| |
26 |
UIUserNotificationTypeSound| |
27 |
UIUserNotificationTypeBadge); |
28 |
UIUserNotificationSettings *settings; |
29 |
settings = [UIUserNotificationSettings settingsForTypes:types |
30 |
categories:categories]; |
31 |
[[UIApplication sharedApplication] registerUserNotificationSettings:settings]; |
要发送这个通知类型,只需简单的将category添加到声明里。
2 |
"alert" : "Pull down to interact." , |
3 |
"category" : "ACTIONABLE" |
现在为了响应用户选择的操作,你需要在UIApplicationDelegate协议添加两个新方法:
1 |
application:handleActionWithIdentifier:forLocalNotification:completionHandler: |
2 |
application:handleActionWithIdentifier:forRemoteNotification:completionHandler |
用户从你的推送通知中选择一个动作后,该方法将会在后台被调用。
01 |
- ( void )application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:( void (^)())completionHandler { |
02 |
if ([identifier isEqualToString:NotificationActionOneIdent]) { |
03 |
NSLog(@ "You chose action 1." ); |
05 |
else if ([identifier isEqualToString:NotificationActionTwoIdent]) { |
06 |
NSLog(@ "You chose action 2." ); |
08 |
if (completionHandler) { |
如文档所述,通过标示符来判定是哪个动作被选中,最后调用completionHandler,即可大功告成。这里仅仅简单的演示了一下iOS 8 新通知API表面上的功能,今后我将更深入的研究一下,有机会再和大家分享。
