My code is
AWSS3TransferManagerUploadRequest *request = [[AWSS3TransferManagerUploadRequest alloc] init];
request.bucket = #"my bucket name";
request.key = #"my cognitio id";
request.body =[NSURL fileURLWithPath:path];
request.contentType = #"image/png";
[[transferManager upload:request] continueWithExecutor:[BFExecutor mainThreadExecutor]
withBlock:^id(BFTask *task) {
NSLog(#"ckmdkcd dvdsv");
if (task.error) {
if ([task.error.domain isEqualToString:AWSS3TransferManagerErrorDomain]) {
switch (task.error.code) {
case AWSS3TransferManagerErrorCancelled:
case AWSS3TransferManagerErrorPaused:
break;
default:
NSLog(#"Error: %#", task.error);
break;
}
} else {
// Unknown error.
NSLog(#"Error: %#", task.error);
}
}
if (task.result) {
AWSS3TransferManagerUploadOutput *uploadOutput = task.result;
// The file uploaded successfully.
NSLog(#"result = %#",task.result);
}
return nil;
}];

I am also setting cognitio id in app delegate.

Based on the fact that you seeing https://cognito-identity.(null).amazonaws.com/ in the error, it would lead me to believe you are not correctly setting the region when creating the AWSCognitoCredentialsProvider. Please double check that you are not setting this to AWSRegionUnknown.
Update 2015-04-17: Here is the list of Region constants. You should set this to the region where your identity pool exists. Currently Amazon Cognito is only available in AWSRegionUSEast1 or AWSRegionEUWest1.
Note, the region of your identity pool has nothing to do the region of other AWS services you may use in your application. You can use an identity pool in AWSRegionUSEast1 to access resources in AWSRegionSAEast1, for instance.
