YLProgressBar

September 25, 2023

The YLProgressBar is an UIProgressView replacement with a highly and fully customizable animated progress bar in pure Core Graphics.

It has been implemented using the Core Graphics framework without any images. So it can be customized freely and independently on the platform.

Usage

Here are some examples to show you how the YLProgressBar can be configured:


                                              
                                                // Blue flat progress, with no stripes

_progressBar.type = YLProgressBarTypeFlat;

_progressBar.progressTintColor = [UIColor blueColor];

_progressBar.hideStripes = YES;
// Green rounded/gloss progress, with vertical animated stripes in the left direction

_progressBar.type = YLProgressBarTypeRounded;

_progressBar.progressTintColor = [UIColor greenColor];

_progressBar.stripesOrientation = YLProgressBarStripesOrientationVertical;

_progressBar.stripesDirection = YLProgressBarStripesDirectionLeft;
// Rainbow flat progress, with the indicator text displayed over the progress bar

NSArray *rainbowColors = @[[UIColor colorWithRed:33/255.0f green:180/255.0f blue:162/255.0f alpha:1.0f],

[UIColor colorWithRed:3/255.0f green:137/255.0f blue:166/255.0f alpha:1.0f],

[UIColor colorWithRed:91/255.0f green:63/255.0f blue:150/255.0f alpha:1.0f],

[UIColor colorWithRed:87/255.0f green:26/255.0f blue:70/255.0f alpha:1.0f],

[UIColor colorWithRed:126/255.0f green:26/255.0f blue:36/255.0f alpha:1.0f],

[UIColor colorWithRed:149/255.0f green:37/255.0f blue:36/255.0f alpha:1.0f],

[UIColor colorWithRed:228/255.0f green:69/255.0f blue:39/255.0f alpha:1.0f],

[UIColor colorWithRed:245/255.0f green:166/255.0f blue:35/255.0f alpha:1.0f],

[UIColor colorWithRed:165/255.0f green:202/255.0f blue:60/255.0f alpha:1.0f],

[UIColor colorWithRed:202/255.0f green:217/255.0f blue:54/255.0f alpha:1.0f],

[UIColor colorWithRed:111/255.0f green:188/255.0f blue:84/255.0f alpha:1.0f]];
_progressBar.type = YLProgressBarTypeFlat;

_progressBar.hideStripes = YES;

_progressBar.indicatorTextDisplayMode = YLProgressBarIndicatorTextDisplayModeProgress;

_progressBar.progressTintColors = rainbowColors;
// To allow the gradient colors to fit the progress width

_progressBar.progressStretch = YES;

You can also use the UIAppearence protocol to configure all the progress bars at once:


                                              
                                                [[YLProgressBar appearance] setType:YLProgressBarTypeFlat];

[[YLProgressBar appearance] setProgressTintColor:[UIColor blueColor]];

Installation

The recommended approach to use the YLProgressBar in your project is using the CocoaPods package manager, as it provides flexible dependency management and dead simple installation.

CocoaPods

Install CocoaPods if not already available:


                                              
                                                $ [sudo] gem install cocoapods

$ pod setup

Go to the directory of your Xcode project, and Create and Edit your Podfile and add YLProgressBar:


                                              
                                                $ cd /path/to/MyProject

$ touch Podfile

$ edit Podfile

source ‘https://github.com/CocoaPods/Specs.git’

platform :ios

pod ‘YLProgressBar’, ‘~> 3.11.0’

Install into your project:


                                              
                                                $ pod install

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


                                              
                                                $ open MyProject.xcworkspace

Manually

Download the project and copy the YLProgressBar folder into your project and then simply #import "YLProgressBar.h" in the file(s) you would like to use it in.
