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

I do not demand to be mentioned in your apps nor to receive any kind of compensation if you use this code. Yet, I would like to have feedbacks if you use it and you like it.
