Installation

CocoaPods

To integrate CYDropDownMenu into your Xcode project using CocoaPods, specify it in your Podfile:

platform :ios, '8.0'
use_frameworks!

target 'YourProjectName' do
   pod 'CYDropDownMenu', '~> 1.0.1'
end

For Swfit, remember to import CYDropDownMenu module before using it.

Manually

Copy the source code in the /CYDropDownMenu folder into your project.

Usage

Just use it like UIView. You could quickly find out how to use it with more details in the Demo project.

Create the CYDropDownMenu and set data:

CGFloat navigationBarHeight = ([UIApplication sharedApplication].statusBarFrame.size.height + (self.navigationController.navigationBar.frame.size.height ?: 0.0));
    
CYDropDownMenu *dropDownMenu = [[CYDropDownMenu alloc] initWithFrame:CGRectMake(0, navigationBarHeight, self.view.frame.size.width, 45)];
dropDownMenu.sectionTitles = @[@"Category", @"Price", @"Distance", @"Order", @"More"];
dropDownMenu.sectionsItems = @[@[@"All",@"Food", @"Hotel", @"Bank", @"Cinema", @"Entertainment"],
                                @[@"$0", @"$1-$100", @"$101-$1000", @">$1000"],
                                @[@"0-10km", @"11-100km", @"101-1000km", @">1000km"],
                                @[@"Recommended", @"Near to me", @"The highest sales", @"Hots"],
                                @[@"24 Hours", @"Available in Holidays"]];
dropDownMenu.autoCenterTitles = YES; //for the case there are only 1 or 2 titles, we center them.
dropDownMenu.delegate = self;
[self.view addSubview:dropDownMenu];

Customization(Optional)

// Additional customizations:
dropDownMenu.sectionTitleColor = UIColor.lightGrayColor;  //The color of top titles
dropDownMenu.sectionTitleTintColor = UIColor.redColor;    //The color of top selected titles
dropDownMenu.itemColor = UIColor.lightGrayColor;          //The color of menu item
dropDownMenu.itemTintColor = UIColor.redColor;            //The color of selected menu item
dropDownMenu.bottomLineHidden = YES;                      //Indicates whether display the bottom line
dropDownMenu.maxMenuHeight = 100;                         //Keep this to nil usually. The Menu height is automatically calculated, and limited in rootview's height. Set this property if you want to limit the height precisely.
dropDownMenu.rootView = self.view;                        //Keep this to nil usually. The ViewController's view will be considered as rootView if the property is not set. Set this property to limite the DropDownMenu and its actions into a particular SubView.

Handle the event

#pragma mark - CYDropDownMenuDelegate
- (void)CYDropDownMenu:(CYDropDownMenu *)dropDownMenu didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
    NSLog(@"Menu item '%@' of section '%@' is selected",dropDownMenu.sectionsItems[indexPath.section][indexPath.row], dropDownMenu.sectionTitles[indexPath.section]);
}

For Swift

We recommend using CocoaPods to integrate the library into your project. Then code it like this:

import UIKit
import CYDropDownMenu

class ViewController: UIViewController,CYDropDownMenuDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        let topbarHeight = UIApplication.shared.statusBarFrame.size.height + (self.navigationController != nil ? self.navigationController!.navigationBar.frame.size.height : CGFloat(0.0))
        let dropDownMenu = CYDropDownMenu(frame: CGRect(x: 0.0, y: topbarHeight, width: self.view.frame.size.width, height: 45.0))
        dropDownMenu.sectionTitles = ["Category", "Price"];
        dropDownMenu.sectionsItems = [["All","Food", "Hotel", "Bank", "Cinema", "Entertainment"],
                                      ["$0", "$1-$100", "$101-$1000", ">$1000"]];
        dropDownMenu.autoCenterTitles = true
        dropDownMenu.delegate = self
        
        self.view.addSubview(dropDownMenu);
    }

    // MARK: CYDropDownMenuDelegate
    func cyDropDownMenu(_ dropDownMenu: CYDropDownMenu!, didSelectItemAt indexPath: IndexPath!) {
        print("Menu item '\(dropDownMenu.sectionsItems[indexPath.section][indexPath.row])' of section '\(dropDownMenu.sectionTitles[indexPath.section])' is selected")
    }
}
