   NSMutableArray *dropdownItems = [[NSMutableArray alloc] init];  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"]];  dropDownMenu.paddingLeft = 15;  // padding left for the content of the button

   dropDownMenu.type = IGLDropDownMenuTypeStack;  dropDownMenu.gutterY = 5;  dropDownMenu.itemAnimationDelay = 0.1;  dropDownMenu.rotate = IGLDropDownMenuRotateRandom;

4. Call the reloadView method (Very Important!)

   // every time you change the params you should call reloadView method  [dropDownMenu reloadView];
