如何在iOS中的GCM注册 [英] How to register for GCM in iOS

问题描述

我似乎无法得到GCM推送通知的工作。我的问题是我不知道如何从GCM获得一个注册ID。我可以从APN令牌就好了。但我不太清楚下一步该怎么做。我试图按照教程，但它不是一个真正为我工作。我是一个初学者，所以请明确。

I can't seem to get GCM push notifications working. My problem is I don't know how to get a registration ID from GCM. I can get a token from APN just fine. But I'm not quite sure what to do next. I tried following the tutorial but its not really working for me. I'm a beginner so please be explicit.

什么我问的是，从获取APN令牌后，再我该怎么办？

What I'm asking is, after obtaining a token from APN, then what do I do?

在此先感谢。

推荐答案

的注册凭证提供给注册的处理程序从didRegisterForRemoteNotificationsWithDeviceToken

The Registration Token is given to the registration handler from didRegisterForRemoteNotificationsWithDeviceToken

所有code下面是从谷歌的GCM取试样。

All code below is taken from the GCM Sample from Google.

首先，在应用程序中声明的处理程序中：didFinishLaunchingWithOptions：

First, declare a handler in your application:didFinishLaunchingWithOptions:

_registrationHandler = ^(NSString *registrationToken, NSError *error){
    if (registrationToken != nil) {
        weakSelf.registrationToken = registrationToken;
        NSLog(@"Registration Token: %@", registrationToken);
        NSDictionary *userInfo = @{@"registrationToken":registrationToken};
        [[NSNotificationCenter defaultCenter] postNotificationName:weakSelf.registrationKey
                                                            object:nil
                                                          userInfo:userInfo];
    } else {
        NSLog(@"Registration to GCM failed with error: %@", error.localizedDescription);
        NSDictionary *userInfo = @{@"error":error.localizedDescription};
        [[NSNotificationCenter defaultCenter] postNotificationName:weakSelf.registrationKey
                                                            object:nil
                                                          userInfo:userInfo];
    }
};

调用处理中的应用程序注册的回调：

Call your handler in the application registration callback:

- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // Start the GGLInstanceID shared instance with the default config and request a registration
    // token to enable reception of notifications
    [[GGLInstanceID sharedInstance] startWithConfig:[GGLInstanceIDConfig defaultConfig]];

_registrationOptions = @{kGGLInstanceIDRegisterAPNSOption:deviceToken,
                         kGGLInstanceIDAPNSServerTypeSandboxOption:@YES};
[[GGLInstanceID sharedInstance] tokenWithAuthorizedEntity:_gcmSenderID
                                                    scope:kGGLInstanceIDScopeGCM
                                                  options:_registrationOptions
                                                  handler:_registrationHandler];
}

的GCM令牌使用简称为* NSString的registrationToken中的登记处理。

The GCM token to use is simply the "NSString *registrationToken" in the registration handler.
