authorizeRequest oAuth not called from another class? - ios

Question

I'm currently using Oauth2SampleTouch by Google, so people can log-in with their google accounts into my app. However whenever I call a method from The SampleRootViewController it doesn't go through the authorizeRequest method (only if I call it from another class.).
Here's the method in SampleRootViewController that I'm calling form another class.(the user is already logged in by this time)
-(NSString *)hasLikedVideo:(NSString *)videoID {
liked = #"NULL";
NSString *clientID = #"myClientID";
NSString *clientSecret = #"myClientSecret";
self.auth = [GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:kKeychainItemName
clientID:clientID
clientSecret:clientSecret];
NSString *urlStr = [NSString stringWithFormat:#"https://www.googleapis.com/youtube/v3/videos/getRating?id=%#&key=AIzaSyB437bMtpbJh-OrkieCDRtYLe6L1Ijb3Ww", videoID];
NSLog(#"URL FOR LIKE : %# auth:(%#)", urlStr, self.auth);
NSURL *url = [NSURL URLWithString:urlStr];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSLog(#"stage 1");
[self.auth authorizeRequest:request
completionHandler:^(NSError *error) {
if (error == nil) {
// the request has been authorized
NSLog(#"ERROR LOADING AUTH 1 : %#", [error description]);
} else {
NSLog(#"ERROR LOADING AUTH 2 : %#", [error description]);
}
NSLog(#"stage 2");
NSString *output = nil;
if (error) {
output = [error description];
NSLog(#"ERROR FROM LOADING LIKE INFO : %#", output);
} else {
NSLog(#"stage 3");
NSURLResponse *response = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&error];
[self displayAlertWithMessage:output];
if (data) {
// API fetch succeeded
NSLog(#"stage 32");
output = [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
// NSLog(#"%#", data);
[self displayAlertWithMessage:output];
} else {
NSLog(#"stage 34");
// fetch failed
output = [error description];
[self displayAlertWithMessage:output];
}
}
NSData* json = [output dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *allCourses = [NSJSONSerialization
JSONObjectWithData:json
options:kNilOptions
error:&error];
NSArray *monday = allCourses[#"items"];
for ( NSDictionary *theCourse in monday )
{
liked = theCourse[#"rating"];
NSLog(#"LIKE INSIDE ARRAY : %#", theCourse[#"rating"]);
}
if( error )
{
NSLog(#"%#", [error localizedDescription]);
}
}];
NSLog(#"stage 4");
return liked;
}
The method runs because I can see it log the string, however it doesn't go through the authorizeRequest, it doesn't even print out the error messages. HOWEVER if my viewController is SampleRootViewController and I call the method from itself it works.
So basically
TestViewcontroller calls a method in SampleRootViewController -> doesn't go through authorizeRequest.
SampleRootViewController calls a method in SampleRootViewController (from itself) -> goes through authorizeRequest and works.
EDIT:
I found out what I was doing "wrong"
I was calling the method like this in background
[self performSelectorInBackground:#selector(getAuthDetails) withObject:nil];
instead of
[self getAuthDetails];
