Run the Demo

$ open Example/ESTMusicIndicator.xcodeproj

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

CocoaPods 0.36 adds supports for Swift and embedded frameworks. You can install it with the following command:

$ gem install cocoapods

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

source 'https://github.com/CocoaPods/Specs.git'  platform :ios, '8.0'  use_frameworks!    pod 'ESTMusicIndicator', '0.1.1'

Then, run the following command:

$ pod install

You can check out this link for more information about how to use CocoaPods.

Manually

Clone this project or download it.
Drag and drop Classes folder to your workspace

Usage

Simple Example:

let indicator = ESTMusicIndicatorView.init(frame: CGRectZero)  indicator.tintColor = UIColor.redColor()  indicator.sizeToFit()  view.addSubview(indicator)

Initially the state property is ESTMusicIndicatorViewStateStopped and the hidesWhenStopped property is YES. Thus, the view is hidden at this time.

The view appears and the bars start animation.

indicator.state = .ESTMusicIndicatorViewStatePlaying;

The bars stop animation and become idle.

indicator.state = .ESTMusicIndicatorViewStatePaused;

The view becomes hidden.

indicator.state = .ESTMusicIndicatorViewStateStopped;

You can use ESTMusicIndicatorView in both code and Storyboard, and it works well with both Auto Layout and frame-based layout.

Code with Auto Layout

let indicator = ESTMusicIndicatorView.init(frame: CGRectZero)  indicator.translatesAutoresizingMaskIntoConstraints = false  view.addSubview(indicator)

Then, add some positioning layout constraints. Note that normally you don't need to add sizing constraints since ESTMusicIndicatorView has an intrinsic content size. It will be automatically resized to fit its content.

Code with Frame-Based Layout

let indicator = ESTMusicIndicatorView.init(frame: CGRectZero)  view.addSubview(indicator)  indicator.sizeToFit() // Resize itself to fit its content.

Customization

Color

The color of the bars can be changed by setting tintColor property (UIView) of the view or its ancestor view.

Size

Normally the view can be automatically resized to fit its content by:

Omitting sizing constraints in Auto Layout, since it has an intrinsic content size.
Calling sizeToFit in frame-based layout.

Or if you explicitly specify size, the bars will be placed in the center of the view.
