How can I get the private SecKeyRef instance from DER encoded private key file?

  • registerForRemoteNotificationTypes causes app to exit immediately

    - by esilver
    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?

  • 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.

  • UITableViewCell checkmark change on select

    - by user333673
    Am I correct in thinking that to change the checkmark for "on" to "off", I must change the CellAccessoryType between none and checkmark on the didSelectRowAtIndexPath? Because I have done this but I have noticed the behaviour is not perfectly identical to like the checkmark cells on the auto lock settings on the iphone. Or is there some other way checkmarks are meant to be handled?

  • 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 to play next file using Audio Queue Services

    - by Stanislav
    What is the right way to play next file using Audio Queue Services? When "play next" button is pressed should I first call AudioQueueStop and then AudioQueuePrime/AudioQueueStart or it is enough to just fill buffers with next file data? The problem is that the latter gives me sound glitches on iPhone.
