I believe,
[[NSUserDefaults standardUserDefaults] synchronize];
will do the trick.

Hi,
I have an application that has no UI. Its settings have to be set by
editing
its defaults file (.plist). I use the following code to register the
defaults at startup:
+ (void) initialize
{
NSMutableDictionary* defaults = [NSMutableDictionary
dictionary];
[defaults setInt:640 forKey:kKey_ScreenWidth];
[defaults setInt:480 forKey:kKey_ScreenHeight];
[defaults setInt:32 forKey:kKey_ScreenDepth];
[defaults setInt:16 forKey:kKey_ZDepth];
[defaults setBool:YES forKey:kKey_VerticalSync];
[defaults setInt:0 forKey:kKey_MaxFPS];
[defaults setBool:YES forKey:kKey_LogFile];
[defaults setInt:8765 forKey:kKey_ServerPort];
[defaults setBool:NO forKey:kKey_HighPriorityThread];
[[NSUserDefaults standardUserDefaults] registerDefaults:defaults];
}
My problem is that, even if I call [[NSUserDefaults
standardUserDefaults]
synchronize] when application quits (it returns true), no file is
written in
~/Library/Preferences/;
According to the doc, it should be written when you call synchronize,
even
if no changes have been made to the defaults...
So I tried changing artificially the defaults before calling
sycnhronize
i.e:
[defaults setBool:![defaults boolForKey:kKey_VerticalSync]
forKey:kKey_VerticalSync];
[defaults setBool:![defaults boolForKey:kKey_VerticalSync]
forKey:kKey_VerticalSync];
Now a file is created but it contains only the key kKey_VerticalSync!
Any idea?
PS: I assume synchronize if buggy.
