Apple Remote Push Notifications

一、帮助文档参考：

https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ProvisioningDevelopment.html#//apple_ref/doc/uid/TP40008194-CH104-SW1

https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/CommunicatingWIthAPS.html#//apple_ref/doc/uid/TP40008194-CH101-SW1

二、服务器证书文件生成文档：

三、APNS全流程：

四、Google描述APNS:

https://code.google.com/p/apns-php/wiki/CertificateCreation

五、APNs之我见：

整个流程中的角色: apple push notification server(aServer), the third push notification server(mServer), APP, iphone(device)

目的：aServer将mServer发送过来的通知推送到device上

条件：1. mServer证书，由于aServer须要区分是谁发送通知过来

　　　2. APP证书，由于aServer一样须要知道通知是对应于哪一个APP的

　　　3. device token, aServer须要知道将通知发送到哪一个地址

六、实际操做流程

1）生成.certSigningRequest文件。方法：apple developer website->APP IDs->选择你须要建立push通知的bundle id编辑Push Notifications那项。有具体文档说明如何生成.certSigningRequest文件

2) 获得aps_development.cer(或者distribution也行)。上传.certSigningRequest文件文件后，apple会自动生成aps_development.cer文件，直接下载而后双击便装进了keychain中

3）生成apns-dev.p12(固然能够是其余名字)文件。在keychain中选择aps_development.cer，右键导出为.p12格式即可

4）生成apns-dev.pem文件。此文件能够直接发给server端用即可。使用此命令（参照上面google的文档）：

openssl pkcs12 -in apns-dev.p12 -out apns-dev.pem -nodes -clcerts

5)xcode工程设置：注意provisioning profile 的bundleID必定要和aps_development.cer证书的bundleID是同样的

6) 在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中register push notification

    if (!TARGET_IPHONE_SIMULATOR && ![[NSUserDefaults standardUserDefaults] objectForKey:DeviceTokenKey]) {

        NSLog(@"Registering for push notifications...");

        

         if([[[UIDevice currentDevice] systemVersion] floatValue] > 7.1)

            [[UIApplication sharedApplication] registerForRemoteNotifications];

         else

            [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

    }

 

7) push notification delegate 

#pragma mark -

#pragma mark  Push Notification

 

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken

{

    NSLog(@"deviceToken: %@", deviceToken);

if (deviceToken != nil)

    {

        NSString *deviceTokenString = [[[[deviceToken description] stringByReplacingOccurrencesOfString:@"<" withString:@""]

                                     stringByReplacingOccurrencesOfString:@">" withString:@""]

                                    stringByReplacingOccurrencesOfString:@" " withString:@""];

        

        if (deviceTokenString) {

            NSLog(@"deviceTokenString = %@", deviceTokenString);

            [[NSUserDefaults standardUserDefaults] setObject:deviceTokenString forKey:DeviceTokenKey];

            [[NSUserDefaults standardUserDefaults] synchronize];

        }

}

}

 

 

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

{

    LogError(@"Error in registration. Error: %@", error);

}

 

 

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

{

    NSLog(@"receive notification date:%@, server send notification info:%@", [NSDate date], userInfo);

    NSString * jsonStr = [userInfo objectForKey:@"acme"];

    NSData *data = [jsonStr dataUsingEncoding:NSUTF8StringEncoding];

    NSDictionary * parsedData = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];

    

    [[NSNotificationCenter defaultCenter] postNotificationName:CloudSeverPushNotification object:parsedData];

    

// [[CloudDriverManager shared] startCloudSync];
