通过Amazon匿名TVM注册用于Amazon (APNS)的iOS设备

Question

类似的问题在StackOverflow上也出现过几次，但亚马逊的SNS却没有解决方案。

这份文件声明，为Amazon ( an )注册设备可以通过匿名令牌供应商机器完成。这份文件为部署提供了一个模板，我已经使用过该模板，然后此代码示例指定了一个演示其使用的iOS客户端。但是，没有在模板配置源或iOS客户机示例中看到TVM是如何链接到SNS应用程序以创建设备条目(称为端点)的。有什么想法吗？

事实证明，引用是链接客户端。解决办法如下：

Include:

AWSRuntime.framework
AWSSecurityTokenService.framework
AWSSNS.framework


#define SNS_PLATFORM_APPLICATION_ARN @"Insert ARN here"
#define TOKEN_VENDING_MACHINE_URL @"Insert vending machine url, found in output tab"
#define USE_SSL 1

#pragma mark - Amazon TVM


+ (void)initSNS
{
    AmazonCredentials *credentials = [AmazonKeyChainWrapper getCredentialsFromKeyChain];

    sns = [[AmazonSNSClient alloc] initWithCredentials:credentials];
    sns.endpoint = [AmazonEndpoints snsEndpoint:US_WEST_2];

    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeAlert |
     UIRemoteNotificationTypeSound];
}

+ (AmazonTVMClient *)tvm
{
    if (tvm == nil) {
        tvm = [[AmazonTVMClient alloc] initWithEndpoint:TOKEN_VENDING_MACHINE_URL useSSL:USE_SSL];
    }

    return tvm;
}

+ (bool)hasCredentials
{
    return ![TOKEN_VENDING_MACHINE_URL isEqualToString:@"CHANGE ME"];
}

+ (Response *)validateCredentials
{
    Response *ableToGetToken = [[Response alloc] initWithCode:200 andMessage:@"OK"];

    if ([AmazonKeyChainWrapper areCredentialsExpired]) {

        @synchronized(self)
        {
            if ([AmazonKeyChainWrapper areCredentialsExpired]) {

                ableToGetToken = [[self tvm] anonymousRegister];

                if ( [ableToGetToken wasSuccessful])
                {
                    ableToGetToken = [[self tvm] getToken];

                    if ( [ableToGetToken wasSuccessful])
                    {
                        [AppDelegate initSNS];
                    }
                }
            }
        }
    }
    else
    {
        [AppDelegate initSNS];
    }

    return ableToGetToken;
}
