I am trying to create an application support directory for my app ( on 10.8.3 )
I am using this piece of example code ( from the docs ) :-
NSString* bundleID = [[NSBundle mainBundle] bundleIdentifier];
NSFileManager*fm = [NSFileManager defaultManager];
NSURL* dirPath = nil;
// Find the application support directory in the home directory.
NSArray* appSupportDir = [fm URLsForDirectory:NSApplicationSupportDirectory
inDomains:NSUserDomainMask];
if ([appSupportDir count] > 0)
{
// Append the bundle ID to the URL for the
// Application Support directory
dirPath = [[appSupportDir objectAtIndex:0]
URLByAppendingPathComponent:bundleID];
// If the directory does not exist, this method creates it.
// This method call works in OS X 10.7 and later only.
NSError* theError = nil;
if (![fm createDirectoryAtURL:dirPath withIntermediateDirectories:YES
attributes:nil error:&theError])
{
// Handle the error.
}
}
When I run the code, bundleID is nil.
Is there something that I have to do to give my bundle an ID ?
I have checked the methods of NSBundle ( and NSBundle docs generally ) but
cannot see anything that looks promising.
Ultimately, I need to store some user modifiable files -
I am assuming that NSApplicationSupportDirectory is the correct place to do
this.
