I've converted from using MGTwitterEngine to the new iOS 5.0 twitter API. My app works like a champ when running in the simulator. However, when I run it on the iPad (a device) performRequestWithHandler always ends up with a request timeout. I have allowed my app access to my Twitter account, and the official iPad Twitter client (which is also using the new iOS 5.0 twitter api) works fine.
I am at a loss why it will not work on the device when it works great in the simulator.
My iPad is running software version 5.0.1 (9A405)
Turns out that my issue was related to making the Twitter calls within a NSOperation. I noticed on the device if I brought up other UIViews (or generally manipulated the UI) it would complete the Twitter execution. If I did not touch the UI and wait, it would timeout. So it seems the Twitter operations on a non-main thread behaved differently between the simulator and on an actual device.
Pulling all of my TWRequest calls into the main thread solved the issue.
I did not experience this problem with my prior implementation using MGTwitterEngine.
Is anyone aware of different thread behavior of the iOS 5.0 Twitter framework?
