FFCircularProgressView – An iOS 7-inspired blue circular progress view

This progress view is inspired by the new progress view in the App Store, iOS 7. Also the colors are taken from there.

See it in action

Requirements

FFCircularProgressView works on iOS version > 5 and is compatible with both ARC and non-ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

Foundation.framework
UIKit.framework
CoreGraphics.framework
QuartzCore.framework

You will need LLVM 3.0 or later in order to build FFCircularProgressView.

Adding FFCircularProgressView to your project

There are plenty of ways to add this view to your project. Make sure you add the aforementioned frameworks to your project as well.

GIT submodule

You have the canonical git submodule option. Simply issue git submodule add https://github.com/elbryan/FFCircularProgressView.git <path> in your root folder of your repository.

CocoaPods

Add a pod entry to your Podfile dependencies file such as pod 'FFCircularProgressView', '>= 0.1'.
Install the pod(s) by running pod install.
Import the progress view with `#import “FFCircularProgressView.h” wherever you need in your project.

Source files

Manually add the source files to your project. The files you need are ‘FFCircularProgressView.h’, ‘FFCircularProgressView.m’, ‘UIColor+iOS7.h’, ‘UIColor+iOS7.m’.

Usage

Just use it as it is a normal UIProgressView. Make sure you set the progress value in the main thread 😉


                                              
                                                double delayInSeconds = 2.0;

dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));

dispatch_after(popTime, dispatch_get_main_queue(), ^(void){

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND,0), ^{

for (float i=0; i<1.1; i+=0.01F) {

dispatch_async(dispatch_get_main_queue(), ^{

[circularProgressView setProgress:i];

});

usleep(10000);

}

});

});

You can also control the progress view spin animation by using the following two methods to start and stop the spinning, respectively:


                                              
                                                // Start spinning

[circularProgressView startSpinProgressBackgroundLayer];
// Stop spinning

[circularProgressView stopSpinProgressBackgroundLayer];

Acknowledgments

The code to draw the tick has been adapted from GSProgressView.
