2、服务器证书文件生成文档：

3、APNS全流程：

4、Google描述APNS:
https://code.google.com/p/apns-php/wiki/CertificateCreation
5、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，因为aServer需要区分是谁发送通知过来
2. APP证书，因为aServer同样需要知道通知是对应于哪个APP的
3. device token, aServer需要知道将通知发送到哪个地址
6、实际操作流程
1）生成.certSigningRequest文件。方法：apple developer website->APP IDs->选择你需要创建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) 得到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，直接下载然后双击便装进了keychain中
3）生成apns-dev.p12(当然可以是其他名字)文件。在keychain中选择aps_development.cer，右键导出为.p12格式便可
4）生成apns-dev.pem文件。此文件可以直接发给server端用便可。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一定要和aps_development.cer证书的bundleID是一样的
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];
}
