我正在关注亚马逊文档，但它不像宣传的那样工作。我也有最新的sdk。下面的 self.identity = 代码不起作用，因为它是只读的。
@implementation DeveloperAuthenticatedIdentityProvider
/*
* Use the token method to communicate with your backend to get an
* identityId and token.
*/
- (AWSTask <NSString*>) token {
//Write code to call your backend:
//Pass username/password to backend or some sort of token to authenticate user
//If successful, from backend call getOpenIdTokenForDeveloperIdentity with logins map
//containing "your.provider.name":"enduser.username"
//Return the identity id and token to client
//You can use AWSTaskCompletionSource to do this asynchronously
// Set the identity id and return the token
self.identityId = response.identityId;
return [AWSTask taskWithResult:response.token];
}
@end
我如何克服这个？谢谢。
