DAProgressOverlayView

A UIView subclass displaying download progress. Looks similarly to springboard icons of apps being downloaded in iOS 7.

Installing

Usage

1) Create overlay view with your view bounds, and add it:

self.progressOverlayView = [[DAProgressOverlayView alloc] initWithFrame:self.imageView.bounds]; //Create new view
[self.imageView addSubview:self.progressOverlayView]; //Add as subview
[self.progressOverlayView displayOperationWillTriggerAnimation]; //Play start animation

2) Update overlay progress level:

self.progressOverlayView.progress = progress;

3) Catch animation finish:

__weak DAViewController *wself = self;
[self.progressOverlayView setAnimationCompletionHandler:^(DAProgressOverlayAnimationType type) {
    if (type == DAProgressOverlayAnimationFinish) {
        wself.progressOverlayView = nil;
    }
}];
