Hi there, beautiful progress indicator. I'm getting some strange artifacts though (see below)
I set up the view in interface builder, using constraints to lay it out. Then the following code to control it:
@IBOutlet weak var progressView: DAProgressOverlayView!
override func viewDidLoad() {
...
self.progressView.displayOperationWillTriggerAnimation()
}
func videoCompletedFrames(completed: Int32, ofTotal total: Int32) {
let percent = Float(completed) / Float(total)
dispatch_async(dispatch_get_main_queue()) {
self.progressView.progress = CGFloat(percent)
}
}
How to display this to collectionviewcell?
timer not set to nil after invalidated, result in memory leak!
- (void)update
{
CGFloat animationProggress = self.animationProggress + DAUpdateUIFrequency / self.stateChangeAnimationDuration;
if (animationProggress >= 1.) {
self.animationProggress = 1.;
[self.timer invalidate];
self.timer = nil;// ADD THIS LINE RESOLVE THE ISSUE
} else {
self.animationProggress = animationProggress;
}
[self setNeedsDisplay];
}
