title: Search for a particular string in a process memory using GDB in OSX
body: <p>I have to find a button's name in a running process memory in Mac OSX and change it. </p>
  
  <p>Supposing there is a "Test" application where it has a "Hello" button, is there any way to attach to "Test" application and change the "Hello!" button to "Bye!"? </p>
  
  <p>I assume this could be done either using GDB or Xcode. If not, how can I do this?</p>
