• How to keep MPMoviePlayerController open after movie ended?

  - by redguy

  If I use MPMoviePlayerController to play video in my iPhone app, it opens, loads the movie, plays it and then closes. Is it possible to force it to stay open after the movie finishes, so that user can replay it using its controls, instead of using controls in parent view? Also, is it possible to start MPMoviePlayerController in the paused mode? thanks for any advice.

• How can I parse raw email source and extract the HTML part?

  - by Matthew Brindley

  In my iPhone app, I'm handed the raw source of an email, in RFC822 (or "eml") format. I'd like the HTML part of this message (if one exists). Rather than attempting to parse it out myself and converting escape chars and so on, I thought I'd check to see if anyone knows of an objective-c library to do this for me. In .NET, I've always used the Mailbee classes for anything email related, but I can't seem to find anything similar for cocoa.

  I'm seeing behaviour on my iPhone where debug builds immediately exit after a call to [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert]; The debugger reports it exited with the message Terminating in response to SpringBoard's termination. This behaviour doesn't happen on my ad hoc distribution builds. Can anyone explain this behavior?

• UIControlEventTouchDragExit only fires ~100 pixels out

  - by Jonathan

  Im trying to "get" when a finger/touch leaves a UIButton in objective C for iphone. I was told in another answer to use UIControlEventTouchDragExit however this event only fires when the touch gets about 100 pixels away from the button, whereas I would like it to be immediate. The apple docs say that goes according to the bounds however my understand is the bounds and the frame are the same unless you rotate the UIbutton (or whatever)

  - by Rob

  Hi there, I'm working on an iPhone app that lets the user draw using GL. I used the GLPaint sample code project as a firm foundation, but now I want to add the ability for the user to load one of their previous drawings and continue working on it. I know how to get the framebuffer contents and save it as a UIImage. Is there a way for me to take the UIImage and tell GL to draw that? Any help is much appreciated.
