   IGLDropDownItem *item = [[IGLDropDownItem alloc] init];
   [item setIconImage:[UIImage imageNamed:@"icon.png"]];
   [item setText:@"title"];
   [dropdownItems addObject:item];

2. Create your IGLDropDownMenu and set the up the parameter name dropDownItems

   IGLDropDownMenu *dropDownMenu = [[IGLDropDownMenu alloc] init];
   [dropDownMenu setFrame:CGRectMake(0, 0, 200, 45)];
   dropDownMenu.menuText = @"Choose Weather";
   dropDownMenu.menuIconImage = [UIImage imageNamed:@"chooserIcon.png"]];
