FFCircularProgressView

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.

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];
