目前分为四个推送:用户推送,本地推送,远程推送,地理位置推送。
- if (IS_IOS8) {
- //1.创建消息上面要添加的动作(按钮的形式显示出来)
- UIMutableUserNotificationAction *action = [[UIMutableUserNotificationAction alloc] init];
- action.identifier = @"action";//按钮的标示
- action.title=@"Accept";//按钮的标题
- action.activationMode = UIUserNotificationActivationModeForeground;//当点击的时候启动程序
- // action.authenticationRequired = YES;
- // action.destructive = YES;
- UIMutableUserNotificationAction *action2 = [[UIMutableUserNotificationAction alloc] init];
- action2.identifier = @"action2";
- action2.title=@"Reject";
- action2.activationMode = UIUserNotificationActivationModeBackground;//当点击的时候不启动程序,在后台处理
- action.authenticationRequired = YES;//需要解锁才能处理,如果action.activationMode = UIUserNotificationActivationModeForeground;则这个属性被忽略;
- action.destructive = YES;
- //2.创建动作(按钮)的类别集合
- UIMutableUserNotificationCategory *categorys = [[UIMutableUserNotificationCategory alloc] init];
- categorys.identifier = @"alert";//这组动作的唯一标示,推送通知的时候也是根据这个来区分
- [categorys setActions:@[action,action2] forContext:(UIUserNotificationActionContextMinimal)];
- //3.创建UIUserNotificationSettings,并设置消息的显示类类型
- UIUserNotificationSettings *notiSettings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIRemoteNotificationTypeSound) categories:[NSSet setWithObjects:categorys, nil nil]];
- [application registerUserNotificationSettings:notiSettings];
- }else{
- [application registerForRemoteNotificationTypes: UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound];
- }
一、通过调用 [[UIApplicationsharedApplication]registerForRemoteNotifications];来实现
application:didRegisterForRemoteNotificationsWithDeviceToken:和application:didFailToRegisterForRemoteNotificationsWithError:的回调
二、设置 UIUserNotificationAction和UIMutableUserNotificationCategory
UIUserNotificationAction的设置:
UIMutableUserNotificationAction *cancelAction = [[UIMutableUserNotificationAction alloc] init];
[cancelAction setIdentifier:@"CancelNotificationActionIdentifier"];
[cancelAction setTitle:@"Cancel"];
[cancelAction setActivationMode:UIUserNotificationActivationModeBackground];
[cancelAction setAuthenticationRequired:YES];
[cancelAction setDestructive:YES];
identifier
User notificaton aciton的唯一标示
title
User notificaton aciton button的显示标题
activationMode
UIUserNotificationActivationModeForeground 激活App并打开到前台展示
UIUserNotificationActivationModeBackground 在后台激活App,测试时发现如果没有启动App(App不在后台也没有打开),那么执行这种模式下的操作,App不会打开;如果App已经在前台了,那么执行这种模式下的操作,App依然在前台。
authenticationRequired
如果设置为YES,执行这个操作的时候必须解锁设备,反之,无需解锁。
如果activationMode为UIUserNotificationActivationModeForeground时,authenticationRequired被作为YES处理。
测试时发现,如果用户设备有密码,在锁屏时authenticationRequired设置为YES执行操作时需要用户输入密码,如果设置为NO则不需要用户输入密码,如果用户设备没有密码,那么无论如何设置都不需要输入密码。
destructive
标示操作按钮是否为红色,只有在锁屏和从通知中心向左滑动出现时才有这种突出显示,在顶部消息展示时没有这种突出效果。
UIMutableUserNotificationCategory的设置:
UIMutableUserNotificationCategory *notificationCategory = [[UIMutableUserNotificationCategory alloc] init];
[notificationCategory setIdentifier:@"NotificationCategoryIdentifier"];
[notificationCategory setActions:@[acceptAction, cancelAction]
forContext:UIUserNotificationActionContextDefault];
identifier
category的唯一标示,identifier的值与payload(从服务器推送到客户端的内容)中category值必须一致。
actions
UIUserNotificationAction 数组,如果设置为nil,那么将不会显示操作按钮。
context
UIUserNotificationActionContextDefault 通知操作的默认Context,在这种情况下,你可以指定4个自定义操作。(还未验证)
UIUserNotificationActionContextMinimal 通知操作的最小Context,在这种情况下,你可以指定2个自定义操作。(还未验证)
三、设置 UIUserNotificationSettings
UIUserNotificationType notificationTypes = (UIUserNotificationTypeAlert|
UIUserNotificationTypeSound|
UIUserNotificationTypeBadge);
NSSet *categoriesSet = [NSSet setWithObject:notificationCategory];
UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:notificationTypes
categories:categoriesSet];
设置通知所支持的类型和Category,这里没有难点,不过多解释。
四、注册通知 registerUserNotificationSettings
[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
在iOS8中通过以上方式注册通知,可以根据操作系统版本做区分处理
五、处理回调事件
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler
{
if([identifier isEqualToString:@"CancelNotificationActionIdentifier"])
{
NSLog(@"You chose cancel action.");
}
else if ([identifier isEqualToString:@"AcceptNotificationActionIdentifier"])
{
NSLog(@"You chose accept action.");
}
if(completionHandler)
{
completionHandler();
}
}
application
收到通知的对象
identifier
UIUserNotificationAction的唯一标示
userInfo
payload的内容
completionHandler
当执行完指定的操作后,必须在最后调用这个方法
