推送通知在iOS8中变化

真机环境，推送要证书和配置文件，app id中bundle id必须和程序中的一致，三种形式：锁屏、解锁情况下运行其他程序、这个程序正在运行

1.在oc中：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // Override point for customization after application launch.

    //注册推送

    if ([[[UIDevicecurrentDevice]systemVersion]floatValue]<8.0) {

        [[UIApplicationsharedApplication]registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound) ];

    }else{//下面两个方法都要写

        [[UIApplicationsharedApplication]registerForRemoteNotifications];

        [[UIApplicationsharedApplication]registerUserNotificationSettings:[UIUserNotificationSettingssettingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSoundcategories:nil]];

    }

用推送打开的程序在launchOptions中有信息（锁屏、解锁情况下运行其他程序）

NSDictionary *pushNotificationKey = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

   if (pushNotificationKey) {//这里处理推送消息

        UIAlertView *alert = [[UIAlertViewalloc]initWithTitle:@"推送通知"message:@"这是推送窗口打开的程序，你可以在这里处理推送内容"delegate:nilcancelButtonTitle:@"OK"otherButtonTitles:nil,nil];

        [alertshow];

    }

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{//注册成功会调用的

   NSString *tokenString = [deviceToken description];

    NSLog(@"apns--->生成的token=%@",tokenString);

要把这个值去掉<>后传给服务器

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{

    NSLog(@"apns-->注册推送时发生错误，信息是：%@",error);

  

失败后会调用一般是（测试的时候遇到问题 未找到应用程序的“aps-environment”的权利字符串"），appid中bundle id不一致或是证书选错<有推送功能的appid，单击edit，下载那里面的证书>

收到推送通知会调用的（正在运行程序）

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{

   NSLog(@"%s %s 推送的消息：%@",__FILE__,__FUNCTION__, userInfo);

    application.applicationIconBadgeNumber =0;

   if ([[userInfo objectForKey:@"aps"]objectForKey:@"alert"]!=NULL) {

        UIAlertView *alert = [[UIAlertViewalloc]initWithTitle:@""message:[[userInfo objectForKey:@"aps"]objectForKey:@"alert"]delegate:selfcancelButtonTitle:@"关闭"otherButtonTitles:@"处理推送消息",nil];

        [alertshow];

2.swift中：把8中（else中）方法换成下面的（两个都要写）

UIApplication.sharedApplication().registerForRemoteNotifications()

UIApplication.sharedApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Alert|UIUserNotificationType.Badge|UIUserNotificationType.Sound, categories: nil))
