使用AWS开发工具包iOS登录AWS控制台

Question

I'm currently exploring AWS SNS, to integrate AWS SNS using AWS iOS SDK.

The guide shows that we have to use Amazon Cognito for authentication and then we can register the device token in the application created in AWS SNS.

Guide that I'm following - https://medium.com/aws-activate-startup-blog/a-guide-to-amazon-simple-notification-service-mobile-push-self-registration-for-ios-a2502e8d5fbd#.mt7t7ed89

After integrating this in my project - I get this error:

Error 
Domain=com.amazonaws.AWSSNSErrorDomain 
Code=1 "The operation couldn’t be completed. (com.amazonaws.AWSSNSErrorDomain error 1.)" 
UserInfo=0x12847e0 
{   
    Type=Sender, 
    Message=User: arn:aws:sts::xxxxxxxxx:assumed-role/xxxxxxxxxxxxxxx/CognitoIdentityCredentials is not authorized to perform: SNS:CreatePlatformEndpoint on resource: arn:aws:sns:ap-south-1:xxxxxxxxx:app/xxxxxxxxxxxxxxxxxxxx, 
    __text=(
    "\n    ",
    "\n    ",
    "\n    ",
    "\n  "
    ),
Code=AuthorizationError}

So please help me out to proceed.

Let me know steps to integrate AWS APIs for Authentication Flow in iOS.

Thanks.

I'm sorry that you're having trouble with this.
Do check if you have added SNS:CreatePlatformEndpoint to the policy for both Auth and Unauth roles on the specified resource.

It should look something like...

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "sns:CreatePlatformEndpoint"
            ],
            "Resource": [
                "arn:aws:sns:ap-south-1:xxxxxxxxx:app/xxxxxxxxxxxxxxxxxxxx"
            ]
        }
    ]
}
