RussianThe method, tableView:viewForTableColumn:row: needs to return an NSView or a subclass of NSView. It looks like [usbInfor valueForKey:identifier], where identifier is "name", returns a string ([mountPath substringFromIndex:9]). I don't know what you're trying to do there, but that's clearly wrong.
NSTableView error -[__NSCFConstantString setFrame:]

Pregunta
all. when I use NSTableView, it will give me the following errors as long as it reaches in this function.
-(id)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row{
USBInfor* usbInfor = [_tableContent objectAtIndex:row];
NSString* identifier = [tableColumn identifier];
return [usbInfor valueForKey:identifier];
}
I created a usbInfor class to save name, size, path, and type of USB. And I add those variables into _tableContent NSMutableArray.
USBInfor *usbinfor = [[USBInfor alloc]init];
usbinfor.name = [mountPath substringFromIndex:9];
usbinfor.path = mountPath;
usbinfor.size = formattingSize;
usbinfor.type = type;
[_tableContent addObject:usbinfor];
I created 3 columns in xib file and each of the identifier I named the same as the variables' name which are name, path, and size.
Here are the errors:

It has to run under OS X 10.5 and the base SDK OS X 10.7
Thanks !!

[tableColumn identifier] is used to identify a column name. So it should be something like
NSString *filename = [[itemArray1 objectAtIndex:rowIndex] objectForKey:key1a];
NSString *path = [[itemArray1 objectAtIndex:rowIndex] objectForKey:key1b];
NSString *identifier = [tableColumn identifier];
if ([identifier] isEqualToString:@"whatever a column name is"]) {
return filename;
}
else if ([identifier] isEqualToString:@"whatever a column name is"]) {
return path;
}
