Get path for NSFileWrapper
No, there's no way to get the full path from NSFileWrapper
.
If you're using NSDocument
you can get the path of regular-file file wrappers with a little hack.
First create a NSFileWrapper
subclass and overload the regular-file methods that receive a URL to store a copy of it.
@implementation RMFileWrapper
- (id) initWithURL:(NSURL *)url options:(NSFileWrapperReadingOptions)options error:(NSError *__autoreleasing *)outError {
if (self = [super initWithURL:url options:options error:outError]) {
self.originalURL = url;
}
return self;
}
- (BOOL) readFromURL:(NSURL *)url options:(NSFileWrapperReadingOptions)options error:(NSError *__autoreleasing *)outError {
BOOL successful = [super readFromURL:url options:options error:outError];
if (successful) {
self.originalURL = url;
}
return successful;
}
@end
Then add this NSFileWrapper
category:
@implementation NSFileWrapper(bestURLWithDocument)
- (NSURL*) bestURLInDocument:(SBDocument*)document {
if (document.fileURL && self.filename) {
NSString* path = [document.fileURL.path stringByAppendingPathComponent:self.filename];
return [NSURL fileURLWithPath:path];
} else if ([self isKindOfClass:[RMFileWrapper class]]) {
RMFileWrapper *fileWrapper = (RMFileWrapper*) self;
return fileWrapper.originalURL;
}
return nil;
}
@end
bestURLInDocument:
will return the url of the file-system node if available, or the original file url if not.
The above code assumes that you're not nesting directory file wrappers.
