Answer 1

Probably twitter is just down and your code is fine.

Answer 2

What worked for me: Go to your twitter app and in Settings set Application Type to "Read and Write".

Now i tried this and the app still gave me the same error. I then opened my twitter account ( the one you are using to login). Click on Settings and Applications and check what the access is against the app that you've made. In case it is Read only, revoke access, go to your iPhone simulator and Reset Content and Settings (you can do this by clicking iOS Simulator on the menu on top of your screen) . Compile the program again and try checking the Reads-Write access in your twitter account now.

This worked for me because basically when i ran the program for the first time, the Application Type was set to Read Only. Changing the Application Type after that doesn't make a difference.

ps: I left the Callback URL blank.

There are two reason: 1. Make sure when you create your application its not "Read Only". 2. Select the Client side application instead of browser/web application.
