iOS 推送通知的实现

来源：互联网发布：php 源码加密代码编辑：程序博客网时间：2024/05/16 10:15

消息推送：分为本地通知和远程通知，区别为：

本地通知由由应用程序计划，并同一设备上的iOS发出；
推送通知，又叫远程通知，由远程服务器上的程序（提供者）发至APNs，再由APNs把消息推送至设备上的某个程序。

有码有真相：

首先需要在APNS上注册推送服务

-(void)alertNotice:(NSString *)title withMSG:(NSString *)msg cancleButtonTitle:(NSString *)cancleTitle otherButtonTitle:(NSString *)otherTitle{UIAlertView *alert;if([otherTitle isEqualToString:@""])alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:cancleTitle otherButtonTitles:nil,nil];elsealert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:cancleTitle otherButtonTitles:otherTitle,nil];[alert show];[alert release];}- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {            // Override point for customization after application launch.    // Add the view controller's view to the window and display.    [self.window addSubview:viewController.view];    [self.window makeKeyAndVisible];[self alertNotice:@"" withMSG:@"Initiating Remote Noticationss Are Active" cancleButtonTitle:@"Ok" otherButtonTitle:@""];//注册远程推送    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound)];        return YES;}

接着，APNS就会返回一个唯一deviceToken

//注册远程通知成功，APNS将返回唯一标示的设备令牌码deviceToken

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {    //注册远程通知成功//NSLog(@"devToken=%@",deviceToken);NSString* strToken = [NSString stringWithFormat:@"devToken=%@",deviceToken];NSLog(@"%@", strToken);[self alertNotice:@"" withMSG:strToken cancleButtonTitle:@"Ok" otherButtonTitle:@""];}- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{    NSDictionary *aps = [userInfo objectForKey:@"aps"];    //在应用Icon右上角显示推送通知的个数    if (aps && [aps isKindOfClass:[NSDictionary class]]) {        int badgeNumber = [[aps objectForKey:@"badge"] intValue];        if (badgeNumber > 0) {            [UIApplication sharedApplication].applicationIconBadgeNumber = badgeNumber;        }    }}- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {    //注册远程推送失败NSLog(@"Error in registration. Error: %@", err);[self alertNotice:@"" withMSG:[NSString stringWithFormat:@"Error in registration. Error: %@", err] cancleButtonTitle:@"Ok" otherButtonTitle:@""];}

到现在iOS方面的编程已经完工，剩下的就是消息推送后台的设置了

首先，需要制作证书，证书的制作流程，推荐：http://docs.jpush.cn/pages/viewpage.action?pageId=1343727

PS：根据后台语言的不同，最后需要使用的证书文件也不同，Java后台需要使用的就是最后生成证书的秘钥，就是p12证书文件，.Net后台需要再进一步将证书文件生成一个pem文件。
