How to translate the object c into rubymotion to fetch facebook user’s information - rubymotion

Question

I tried to translate part of the objective-c but I still stuck at part of them
any idea ? Thanks so much
objective c version
if ([FBSDKAccessToken currentAccessToken]) {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:#"picture",#"fields",nil];
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"me"
parameters:params
HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
UIImage * downloadedImage = [UIImage imageWithData:pictureData];
dispatch_async(dispatch_get_main_queue(), ^{
self.profilePictureImageView.image = downloadedImage;
});
}];
}
ruby motion version
if (FBSDKAccessToken.currentAccessToken) {
request = FBSDKGraphRequest.alloc.initWithGraphPath("me", parameters:nil, HTTPMethod: "GET")
}

Answer 1

Finally, I came up with the corresponding code in rubymotion
Please correct me directly if anything wrong, it works for me now
part of original objective-c
if ([FBSDKAccessToken currentAccessToken]) {
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"me"
parameters:params
HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
}];
}
convert version by ruby_motion_query
def loginButton(loginButton, didCompleteWithResult: result, error: error)
puts result
puts error
if not error
request = FBSDKGraphRequest.alloc.initWithGraphPath("me", parameters:nil, HTTPMethod: "GET")
request.startWithCompletionHandler( lambda{ |connection, user, error|
#DO_ANYTHING_YOU_WANT_FATE_LOGINING_SUCESSFULLY
rmq(#fb_login_button).animate { |btn| btn.move(b: 400) }
#name_label = rmq.append(UILabel, :label_name).get
#name_label.text = "#{user['first_name']} #{user['last_name']}"
rmq(#name_label).animations.fade_in
})
end
end
def loginButtonDidLogOut(loginButton)
#DO_ANYTHING_YOU_WANT_HERE
end
