I have a slightly odd requirement in that I need to modify, under certain
circumstances, the save path used for an NSDocument based application. The
reason for this is that I may, depending on the format chosen by the user, need
to unpack the data into multiple files. Under this circumstance, I want to
create a folder at the location specified by the user, with the name of the
source file (less the extension) as the folder name, and then I'll unpack the
source file into this directory.
I thought that this would be nice and simple - but it seems that the URL used
when saving is an intermediate URL. My file doesn't get created at the final
destination location (and, because it doesn't, I can't easily modify the path).
What I planned to do is this:
- (BOOL)writeToURL:(NSURL *)url ofType:(NSString *)inTypeName error:(NSError
**)outError
//Bunch of code and then...//
NSString *filename = [[url absoluteString] lastPathComponent];
NSString *directory = [[[url absoluteString]
stringByDeletingLastPathComponent]
stringByAppendingFormat:@"/%@",[filename
stringByDeletingPathExtension]];
NSFileManager *fileManager= [NSFileManager defaultManager];
NSError *error = nil;
if(![fileManager createDirectoryAtPath:directory
withIntermediateDirectories:YES
attributes:nil
error:&error])
{
success = false;
}
else
{
url = [NSURL fileURLWithPath:[NSString
stringWithFormat:@"%@/%@",directory,filename]];
}
When I check url I get something like
file://localhost/private/var/folders/6w/6dmwl9c938g4m94jm7s_8ml80000gn/T/TemporaryItems/(A%20Document%20Being%20Saved%20By%20Extractor)/Christmas.ext
Does anyone have the key to what I should be doing - because I'm clearly
approaching this from the wrong angle!
