问题 Is AVAssetWriterInput's readyForMoreMediaData updated in a background thread? If readyForMoreMediaData is NO, can I block in the main thread and wait until the value changes to YES? I'm using an AVAssetWriterInput by pushing data to it (i.e. without using requestMediaDataWhenReadyOnQueue) and I've set expectsMediaDataInRealTime, and 99.9% of the time I can just call appendSampleBuffer (or appendPixelBuffer) on it as fast as my app can generate frames.

问题 My app just got approved for the apple store. I downloaded it an installed it on my iPhone - but it looks like push notifications are broken! I was successfully testing push notifications in production using an adHoc provisioning profile. I had no problems. The only thing I did differently when I submitted to apple was using an app store distribution profile. The application never asks me (or anyone else who has downloaded it) if I want to receive push notifications. Consequently, the phone

问题 I have a UITableView with style "Grouped" which I use to set some options in my App. I'd like for one of the cells of this UITableView to only show up depending on whether another of this UITableView's cells is activated or not. If it's not, the first cell should show up (preferably with a smooth animation), if it is, the first cell should hide. I tried returning nil in the appropriate -tableView:cellForRowAtIndexPath: to hide the cell, but that doesn't work and instead throws an exception. I

Strangely , the frameworks are red. http://img.skitch.com/20100730-kcjun96mp2pxnpg7w3x6njw57.jpg I tried to locate coreGraphics.framework and UIKit.framework to add them again but i couldnt find them either.
