September 25, 2023

If you use MBCircularProgressBar, please tell me and I will add your app here.

Usage

To run the example project, clone the repo, and run pod update from the Example directory first.

Installation

CocoaPods

MBCircularProgressBar is available through CocoaPods.

To install it, simply add the following lines to your Podfile:

Add this line to the begining of your Podfile in order to support @IBDesignable. More info here (Thanks to: @StevenMasini)


                                              
                                                use_frameworks!

Add this line so with every Pod install/update cocoapods would download the library intro your project:


                                              
                                                pod “MBCircularProgressBar”

Installation with 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 MBCircularProgressBar into your Xcode project using Carthage, specify it in your Cartfile:


                                              
                                                github “MatiBot/MBCircularProgressBar”

Run carthage update to build the framework and drag the built MBCircularProgressBar.framework into your Xcode project.

Directly

You can also download the MBCircularProgressBar{View,Layer}.{m,h} files into your project directly

                                                [UIView animateWithDuration:1.f animations:^{

self.progressBar.value = 55.f;

}];
