This isn't quite correct. "j:mm" is a template, not an actual format string. When you run it through every possible locale, you get this output: http://pastie.org/4683032 The presence of the colon in the template is incidental. It would work just fine if you used "jmm" as well. With the res

I'm going to venture out on a limb and say you shouldn't be using NSDateFormatter for this. NSDateFormatter is really only useful when you're converting a date to-and-from a human-readable form. The way you're using it, it's not human-readable, and will cause you problems in very subtle ways.

Re: Creating an NSExpression with a keypath and variable

Directly, yes. NSExpression stores a keypath as a single string, whereas variables are store in their own kind of NSExpression object. When you replace variables with new values, it's only looking for the certain kinds of NSExpression objects to replace. Everything else stays the same. Some

Re: Unique strings array

Use an NSMutableSet instead. That should have constant lookup time instead of linear (like an array usually is). Dave Sent from my iPhone On Mar 11, 2011, at 6:11 PM, Leonardo wrote: > Hi, > I have to extract a list of "unique words" from an array of hundred > thousands words and put them in

Re: get a dictionary out of an array of dictionaries by a criterion

Load the array into memory. Create an NSPredicate with the predicateFormat: @"ID = %d", myID Use filteredArrayUsingPredicate: The resulting array contains the dictionaries you're looking for. OR Loop through the array and find it yourself. Dave On Mar 9, 2011, at 9:18 AM, Martin Batholdy wrote:

Re: easy way to store table-like data

If you have an array of dictionaries, you can use -filteredArrayUsingPredicate, and pass in the NSPredicate with the format string of @"type = 'website'". You'll get back all the dictionaries where [[dictionary objectForKey:@"type"] isEqual:@"website"]; But if you're using these dictionaries f

Re: Cocoa Application without any menu, dock, etc.

Pretty easy: - add an entry to your Info.plist: "LSUIElement" => true (this is the "Application is agent" entry) It's not necessary to delete the menu from MainMenu.xib, because I believe that's only used when your app lives in the Dock. Leaving it in allows your app to still respond to thin

Alternative: instead of bringing another process forwards, tell yours to hide. Then the previously-frontmost app will be frontmost again. Dave Sent from my iPhone On Feb 9, 2011, at 7:23 AM, "Mr. Gecko" wrote: > Hello, I am wondering how I can get the last front application > ProcessSerialN

Re: Close System Preferences programmatically

Another option would be to have your preference pane launch a little installer that won't proceed until the user quits System Preferences. Something like "In order to uninstall MyAwesomeFoo, please quit System Preferences". Then wait until the app quits, then dismiss the dialog and proceed. Y
