  - by Michael Minerva

  I want to make a widget that displays a column of selectable text data. It seems that the NSBrowser is the best cocoa object to do this but I cannot figure out how to populate the NSBrowser with any sort of data. I assume I can set the string value of an NsBrowserCell but no where in the documentation can I find where to add a new cell to a column. Am I using the wrong object?

• Retrieving Absolute URL from File on Mounted Volume in Cocoa

  - by Bryan Kyle

  Is there any way of retrieving an absolute URL for a file on a mounted volume in Cocoa? For example, say afp://server/Documents is mounted at /Volumes/Documents. How can I get full URL to a file on the mounted volume in the form of afp://server/Documents/path/to/file? I've tried using statfs but the value of f_mntfromname doesn't contain a url, it contains the same value that is given by the mount command.

• Write Secure Cocoa Code

  - by happyCoding25

  Hello, Im making an application in cocoa and wanted to see if some strings in it were easily accessible so I ran OTX on it and sadly all of my code was found. Is there a method I can use to make my code more "secure" or at least encrypt/hide the strings? The reason I want to encrypt the string is it's a password for a server. I don'd need it really secure I just don't want the password to be so easy to find. Thanks for any help

• Cocoa: Creating a Window with a Variable Number of Interface Elements

  - by Rui Pacheco

  Hi, I've a window that will have an unknown amount of text fields, determined by the content of a remote server. In high level terms, how should I go about this?
