Hi,

Here is the code example:

    CGRect frame = CGRectMake(0, 0, 80, 40);

    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [button setTag:j];

    button.frame = frame;

    //set images
    UIImage * imgNormal = [UIImage imageNamed:@"subtabButton.png"];
    [button setBackgroundImage:imgNormal forState:UIControlStateNormal];

    UIImage * imgSelected = [UIImage imageNamed:@"subtabButton_selected.png"];
    [button setBackgroundImage:imgSelected forState:UIControlStateSelected];
    [button setBackgroundImage:imgSelected forState:UIControlStateHighlighted];

    [button setTitle:@"My Button" forState:UIControlStateNormal];

Thanks
