Looks like I've found a workaround:
- (IBAction)formatForTextExportChanged:(id)sender
{
self.textExportFormat = [sender indexOfSelectedItem];
NSString *path =
self.currentSavePanel.nameFieldStringValue.stringByDeletingPathExtension;
switch (self.textExportFormat) {
case 0:
path = [path stringByAppendingPathExtension:@"txt"];
self.currentSavePanel.allowedFileTypes = @[@"txt"];
break;
case 1:
path = [path stringByAppendingPathExtension:@"rtf"];
self.currentSavePanel.allowedFileTypes = @[@"rtf"];
break;
}
self.currentSavePanel.nameFieldStringValue = path;
[[NSUserDefaults standardUserDefaults] setValue:[NSNumber
numberWithInteger:self.textExportFormat]
forKey:ANTextExportFormatKey];
}
By setting the desired file type as the only allowable, the save panel now also
returns the correct file extension, even if the user chose to hide the
extension. If there is a better solution, please tell.
