Hello all, for the last couple of weeks I've finally gotten into Obj-C from regular C and have started my first app. I've watched tutorials and read through a book along with a lot of webpages, but I know I've only just begun. Anyway, for most of the night and this morning, I've been trying to get this code to work, and now that it will compile, I have a few warnings. I've searched and found similar problems with solutions, but still no dice. What I'm trying to do is put an array made from a txt document into the popup list in a combo box.

AwesomeBoxList.h:

    #import <Cocoa/Cocoa.h>
@interface AwesomeBoxList : NSObject 
{
  IBOutlet NSComboBox *ComboBoz;
}
-(NSArray *) getStringzFromTxtz;
- (void) awesomeBoxList;
@end

AwesomeBoxList.m:

#import "AwesomeBoxList.h"

@implementation AwesomeBoxList

-(NSArray *)getStringzFromTxtz 
{
...
return combind;
}

- (void) awesomeBoxList
{
 [ComboBoz setUsesDataSource:YES];


 [ComboBoz setDataSource:

[ComboBoz getStringzFromTxtz]: //'NSComboBox' may not respond to 'getStringzFromTxtz'

[ComboBoz comboBox:(NSComboBox *)ComboBoz objectValueForItemAtIndex: 

 [ComboBoz numberOfItemsInComboBox:(NSComboBox *)ComboBoz]]];


        /*'NSComboBox' may not respond to '-numberOfItemsInComboBox:'
   'NSComboBox' may not respond to '-comboBox:objectValueForItemAtIndex:'
   'NSComboBox' may not respond to '-setDataSource:'
  */
 }

@end

So, with all of these errors and my still shallow knowledge of Obj-C, I must be making some sort of n00b mistake.

Thanks for the help.
