ios--pushnotification学习与总结（推送机制）

第一步熟悉pushnotification以及创建证书，可以通过下面这个网站去熟悉下

http://blog.csdn.net/daydreamingboy/article/details/7977098  （iOS上简单推送通知（Push
Notification）的实现）

第二步，找一个demo学习一下：我在github上面找的一个demo

https://github.com/Turkcell/PushNotification_iOS_sdk

在代码中要做以下的事情：

#pragma mark  --------远程通知
- (void)registerAPNSNotification
{
    //适配8.0,IF走8.0
    if (![[NSUserDefaults standardUserDefaults] boolForKey:kOatosParamsDeviceToken])
    {
        if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {
            UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        }else {
            [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];
        }

    }
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self registerAPNSNotification];
//清除所有本地通知
    [application cancelAllLocalNotifications];
    application.applicationIconBadgeNumber = 0;
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    if ([[UIApplication sharedApplication] enabledRemoteNotificationTypes] == UIRemoteNotificationTypeNone && !isLogout) {
         [self registerAPNSNotification];
    }
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

//注册远程通知成功
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSString *token = [NSString stringWithFormat:@"%@", [[[deviceToken description] stringByReplacingOccurrencesOfString:@"<" withString:@""] stringByReplacingOccurrencesOfString:@">" withString:@""]];
    DLog(@"deviceToken[%@]", token);
    [[NSUserDefaults standardUserDefaults] setObject:token forKey:kOatosParamsDeviceToken];
}

//注册远程通知失败
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    NSString *error_str = [NSString stringWithFormat: @"%@", error];
    DLog(@"获取deviceToken失败[%@]", error_str);
}
