Add/Remove your app from Login Items
These are two methods to add and remove your program from the Login Items list in Mac OS X 10.4.
I didn't write most of the code. It Originally came from http://www.cocoadev.com/index.pl?StartingMyAppOnStartup
I split the original code into 2 methods and made it automatically detect the name of your app.
-You don't have to modify anything to add these to your app. Just drop them into your code.
-OS X keeps the addToLoginItems method from adding your app twice. (sweet!)
-You don't have to check if your app is already listed. The removeFromLoginItems method does it for you.
-This, to me, seem MUCH easier than using Apple's LoginItemsAE class.
- (void)removeFromLoginItems
{
NSString *appName = [[[NSBundle mainBundle] bundlePath] lastPathComponent];
NSString *loginWindowPlistPath = [@"~/Library/Preferences/loginwindow.plist" stringByExpandingTildeInPath];
NSMutableDictionary *loginWindowPrefsDictionary = [NSMutableDictionary dictionaryWithContentsOfFile:loginWindowPlistPath];
NSMutableArray *launchItems = [NSMutableArray arrayWithArray:[loginWindowPrefsDictionary valueForKey:@"AutoLaunchedApplicationDictionary"]];
NSEnumerator *enumerator = [launchItems objectEnumerator];
id application;
while ( application = [enumerator nextObject] ) {
if ( [[[application valueForKey:@"Path"] lastPathComponent] isEqualToString: appName] ) {
// These 4 lines are run if the app is found in "Login Items".
// You can replace these lines with something like "return YES;"
// if you just want a method that checks for your app in the list.
[launchItems removeObject:application];
[loginWindowPrefsDictionary setObject:launchItems forKey:@"AutoLaunchedApplicationDictionary"];
[loginWindowPrefsDictionary writeToFile:loginWindowPlistPath atomically:YES];
return;
}
}
}
- (void)addToLoginItems
{
NSString *fullPath = [[NSBundle mainBundle] bundlePath];
NSString *script = [NSString stringWithFormat:@"set appPath to \"%@\" \ntell application \"System Events\" \nmake login item at end with properties {path:appPath, hidden:false} \nend tell", fullPath];
NSAppleScript *appleScript = [[NSAppleScript alloc] initWithSource:script];
[appleScript executeAndReturnError:nil];
}Compatible with:
- Mac OS X 10.4 PPC
- Mac OS X 10.4 Intel
- Mac OS X 10.5 PPC
- Mac OS X 10.5 Intel
In the method addToLoginItems, a 'release' is never sent to NSAppleScript *appleScript after it's allocated. Seems like a memory leak?
