    If you simply want to use IPC, make both of your apps recognize some URL scheme. Then call

    [[UIApplication sharedApplication] openURL:
  [NSURL URLWithString:@"theOtherApp://dataToShare"]];

    to send, and use -application:handleOpenURL: to receive.

    To share strings via the pasteboard, use 

     UIPasteboard* board = [UIPasteboard generalPasteboard];
 board.string = @"Some string to share";

    to save, and use board.string as a getter to retrieve the string to share. But if the user copy anything in between your shared data will be lost.

    Alternatively, you can share stuff via:

    • AddressBook. Create a dummy contact and use it for sharing.
    • Keychain. Make a Shared Keychain Item. 3.x only.
    • Read/write from shared folders. /var/mobile/Library/AddressBook and Keyboard and Preferences can be accessed even if your app is sandboxed. This may violate SDK rules though.
