  • Works with ARC and iOS >= 5

Installation

CocoaPods

The easiest way of installing HMSegmentedControl is via CocoaPods.

pod 'HMSegmentedControl', '~> 1.1.0'

Cocoa-whaa?

If you haven't heard about CocoaPods (seriously, where were you?!), it's a dependency manager for Xcode projects that provides very simple installation of libraries. Here's how to get started.

Install CocoaPods if not already available:

$ [sudo] gem install cocoapods
$ pod setup

Change to the directory of your Xcode project, and Create and Edit your Podfile and add HMSegmentedControl:

$ cd /path/to/MyProject
$ touch Podfile
$ edit Podfile
platform :ios, '5.0' 
pod 'HMSegmentedControl', '~> 1.2.0'

Install into your project:

$ pod install

Open your project in Xcode from the .xcworkspace file (not the usual project file)

$ open MyProject.xcworkspace

Old-fashioned way

  • Add HMSegmentedControl.h and HMSegmentedControl.m to your project.
  • Add QuartzCore.framework to your linked frameworks.
  • #import "HMSegmentedControl.h" where you want to add the control.

Usage

The code below will create a segmented control with the default looks:

HMSegmentedControl *segmentedControl = [[HMSegmentedControl alloc] initWithSectionTitles:@[@"One", @"Two", @"Three"]];
[segmentedControl setFrame:CGRectMake(10, 10, 300, 60)];
[segmentedControl addTarget:self action:@selector(segmentedControlChangedValue:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:segmentedControl];

Included is a demo project showing how to fully customise the control.
