Requirements

• Works on any iOS device

Example

Getting Started

Installation

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

pod "BALoadingView"

Simple Usage

startAnimation:

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

stopAnimation removes the animations from the view.

Advanced Usage

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

Initialize

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

Duration

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:

Clockwise

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:

Segment Color

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

Line Cap

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:
