Okay, so I think I know what the problem is here - the problem is that I prompt
the user for a filename, and then I modify the filename before using it. I
suspect that sandboxd looks dimly on what I've done, and considers me to be
riding roughshod over the users wishes! In fact I'm not, but there's no way
for sandboxd to know this!
Here's the problem. I'm writing out (potentially) very large files. It might
be that the user doesn't want one huge xml file - instead they might want a
bunch of smaller xml files. Therefore I prompt the user for a filename (which
I use as a base) and then I append a number. So, for example, if the user
specifies that they'd like the file to be called file.xml, I modify this to:
file 1.xml
file 2.xml
file 3.xml and so forth.
I do this with the following code:
else if (([ftype
isEqualToString:@"xml"])&&merge&&(mergeCount>0)&&([outputFile count]>0))
{
newURL = [NSURL URLWithString:[[NSString stringWithFormat:@"%@
%d.xml",[saveFilePath lastPathComponent],mfCount]
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]
relativeToURL:saveFilePath];
NSMutableDictionary* mergedOutputFile = [[NSMutableDictionary
alloc]init];
[mergedOutputFile setObject:[settings objectForKey:@"ElementsArray"]
forKey:@"FormatDefinition"];
[mergedOutputFile setObject:outputFile
forKey:@"Content"];
success = [mergedOutputFile writeToURL:newURL atomically:YES];
if (!success) NSLog(@"Failed to write output file");
}
This code works file until I turn sandboxing on - and then it fails. The
following code works fine in the sandbox, but without the benefit of appended
numerals - making it impossible for me to split the file into chunks.
else if (([ftype
isEqualToString:@"xml"])&&merge&&(mergeCount>0)&&([outputFile count]>0))
{
newURL = [NSURL URLWithString:[[NSString
stringWithFormat:@"%@",[saveFilePath lastPathComponent]]
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]
relativeToURL:saveFilePath];
NSMutableDictionary* mergedOutputFile = [[NSMutableDictionary
alloc]init];
[mergedOutputFile setObject:[settings objectForKey:@"ElementsArray"]
forKey:@"FormatDefinition"];
[mergedOutputFile setObject:outputFile
forKey:@"Content"];
success = [mergedOutputFile writeToURL:newURL atomically:YES];
if (!success) NSLog(@"Failed to write output file");
}
Does anyone have any cunning plan for how I might achieve the functionality
that I need without breaking the sandbox?
