A UIView that offers several loading animations.

• Works on any iOS device

To run the example project, clone the repo, and run pod install from the Example directory first.

BALoadingView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "BALoadingView"

To add a BALoadingView to your app, add the line:

BALoadingView *view = [[BALoadingView alloc] initWithFrame:self.view.frame];
[self.loadingView initialize];
[self.loadingView startAnimation:BACircleAnimationFullCircle];
//OR [self.loadingView startAnimation:BACircleAnimationSemiCircle];

This creates the following animation/button by default:

Passing the BACircleAnimationSemiCircle enum produces:

stopAnimation removes the animations from the view.

Listed below are examples of several properties that you can control.

initialize sets the default values and should be called before setting any properties.

If you want the loading animation to last longer/shorter, you can edit the duration property:

BALoadingView *loadingView = [[BALoadingView alloc] initWithFrame:self.view.frame];
[self.loadingView initialize];
self.loadingView.duration = 20.0f;
self.loadingView.segmentColor = [UIColor whiteColor];
[self.loadingView startAnimation:BACircleAnimationFullCircle];

This creates this view:

Editting the clockwise boolean property changes the direction of the full circle animation:

BALoadingView *loadingView = [[BALoadingView alloc] initWithFrame:self.view.frame];
[self.loadingView initialize];
self.loadingView.clockwise = YES;
self.loadingView.segmentColor = [UIColor whiteColor];
[self.loadingView startAnimation:BACircleAnimationFullCircle];

This creates this view:

the segmentColorproperty controls the color of the segments and can be used like like in the example above

the lineCapproperty controls the end caps for the semi circle animation. The rouded cap option is seen below:

[self.loadingView initialize];
self.loadingView.lineCap = kCALineCapRound;
self.loadingView.clockwise = true;
self.loadingView.segmentColor = [UIColor whiteColor];
[self.loadingView startAnimation:BACircleAnimationFullCircle];

The animation looks like this:
