How To Use

####!Try the demo. It's really helpful!

Sample Code

Create your IGLDropDownItem array and set up

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

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

modify the params of IGLDropDownMenu

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

Call the reloadView method (Very Important!)

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