Tumblr reblog (TMTumblrSDK) return 401 error - ios

Question

I use TMTumblrSDK :
NSDictionary *params = #{
#"id" : 999999999999,
#"reblog_key": #"XXXXXX",
#"comment" : #"test comment",
};
[[TMAPIClient sharedInstance] reblogPost:#"test.tumblr.com"
parameters:params
callback:^(id response, NSError *error) {
...
response:
{
meta = {
msg = "Not Authorized";
status = 401;
};
response = (
);
}
OAuthConsumerKey, OAuthConsumerSecret, OAuthToken, OAuthTokenSecret is set correctly.
Methods "user/follow" "user/like" and "user/unlike" work correctly.

Answer 1

I solved my problem.
In the "reblogPost" value necessary to transmit blog url logged in user, not the blog url, reblogged we want to do.
For example, if we want to do reblogged post of "test" user, we must not pass "test.tumblr.com". We must pass "loggedUser.tumblr.com".
It can be obtained using the method userInfo.
For example:
NSString* baseHostname;
[[TMAPIClient sharedInstance] userInfo: ^(id result, NSError* error) {
NSString * baseHostname = [result[#"user"][#"blogs"][0][#"url"] // first blog
stringByReplacingOccurrencesOfString:#"http:" withString:#""];
baseHostname = [baseHostname stringByReplacingOccurrencesOfString:#"/" withString:#""];
[[TMAPIClient sharedInstance] reblogPost: baseHostname // #"loggedUser.tumblr.com"
parameters: params
callback: ^(id response, NSError * error) {
...
}];
}];
