Installation

**Embedded frameworks require a minimum deployment target of iOS 8

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

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

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'TBDropdownMenu'
end

Then, run the following command:

$ pod install

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate DropdownMenu into your Xcode project using Carthage, specify it in your Cartfile:

github "teambition/DropdownMenu"

Run carthage update to build the framework

At last, you need to set up your Xcode project manually to add the DropdownMenu framework.

On your application targets’ “General” settings tab, in the “Linked Frameworks and Libraries” section, drag and drop each framework you want to use from the Carthage/Build folder on disk.

On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script with the following content:

 /usr/local/bin/carthage copy-frameworks

and add the paths to the frameworks you want to use under “Input Files”:

 $(SRCROOT)/Carthage/Build/iOS/DropdownMenu.framework

For more information about how to use Carthage, please see its project page
