Edit ViewController.h: Add#import "ComboBox.h", declareComboBox* combo1;
The header file should look like this:

{
    ComboBox* combo1;     
}
@end

Edit ViewController.m, add the following toviewDidLoad:

NSMutableArray* fruitsArray = [[NSMutableArray alloc] init];
[fruitsArray addObject:@"Apple"];
[fruitsArray addObject:@"Banana"];
[fruitsArray addObject:@"Orange"];
    
combo1 = [[ComboBox alloc] init];
[combo1 setComboData:fruitsArray]; //Assign the array to ComboBox [self.view addSubview:combo1.view];
combo1.view.frame = CGRectMake(110, 69, 120, 31); //ComboBox location and  //size (x,y,width,height)

Build and run, that's it.
