Dear cocoa-dev,
There is a problem when I try to remove a file from a folder via NSFileWrapper. I don't know if this is an important info, but the folder is inside a "package" (a folder with an extension).
I have a folder "(...)/attached_files" on my disk.
I create a NSFileWrapper with
self.fileWrapper= [[NSFileWrapperalloc] initWithURL:myURL
options:0
error:error] ;
Then, I remove one of the sub-subwrappers with the command
NSFileWrapper * theSubWrapper = [[self.fileWrapper fileWrappers] valueForKey:@"subFolder_1"] ;
NSFileWrapper * theSubSubWrapper = [[theSubWrapper fileWrappers] valueForKey:@"subSubFolder_1"] ;
[theSubWrapper removeFileWrapper:theSubSubWrapper] ;
Then, I save with
[self.fileWrapper writeToURL:myURL
options:NSFileWrapperWritingAtomic| NSFileWrapperWritingWithNameUpdating
originalContentsURL:myURL
error:error] ;
If I open the folder and check if the file has been removed, the file is still there.
But, if I try to open it, the Finder throws an error "The Application does not exist".
If anyone has a good experience with NSFileWrapper, more information about the options of the writeToUrl:... command would be appreciated. Indeed, if I don't use the "NSFileWrapperWritingAtomic", I have an error : "can't write because the file already exists".
Thanks to all !!
Colas
