Question

I am developing an app for iOS > 4.3.

Answer 1

You could use UIPasteboard,

while setting:

   UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
   [pasteboard setString:yourtext];

while getting (if you have a label):

   UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
   pastelabel.text =  [pasteboard string];

and you can refer Pasteboard Programming Guide for more details.
