Customization

Default Property Values

Animation delay : delay = 0.2
Animation duration : duration = 0.8
Number of circles : numberOfCircles = 5
Circle's radius : radius = 10
Circle's internal spacing : internalSpacing = 5
Circle's background Color : defaultColor = [UIColor lightGrayColor]

Custom Property Values

- (void)viewDidLoad {
  [super viewDidLoad];
  
  MONActivityIndicatorView *indicatorView = [[MONActivityIndicatorView alloc] init];
  indicatorView.numberOfCircles = 3;
  indicatorView.radius = 20;
  indicatorView.internalSpacing = 3;
  indicatorView.duration = 0.5;
  indicatorView.delay = 0.5
  indicatorView.center = self.view.center;
  [self.view addSubview:indicatorView];
  [indicatorView startAnimating];
}

Custom Circle's Background Color

First, assign the MONActivityIndicatorViewDelegate protocol to a view controller. Then, implement the method activityIndicatorView:circleBackgroundColorAtIndex:

@interface ViewController : UIViewController <MONActivityIndicatorViewDelegate>

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  
  MONActivityIndicatorView *indicatorView = [[MONActivityIndicatorView alloc] init];
  indicatorView.delegate = self;
  indicatorView.numberOfCircles = 3;
  indicatorView.radius = 20;
  indicatorView.internalSpacing = 3;
  indicatorView.duration = 0.5;
  indicatorView.delay = 0.5
  indicatorView.center = self.view.center;
  [self.view addSubview:indicatorView];
  [indicatorView startAnimating];
}

- (UIColor *)activityIndicatorView:(MONActivityIndicatorView *)activityIndicatorView
      circleBackgroundColorAtIndex:(NSUInteger)index {
  // For a random background color for a particular circle
  CGFloat red   = (arc4random() % 256)/255.0;
  CGFloat green = (arc4random() % 256)/255.0;
  CGFloat blue  = (arc4random() % 256)/255.0;
  CGFloat alpha = 1.0f;
  return [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
}
