2. Just initiate and add to your view layer.

PulsingHaloLayer *halo = [PulsingHaloLayer layer];
halo.position = self.view.center;
[self.view.layer addSublayer:halo];

###Install with CocoaPods

Edit your Podfile.

pod "PulsingHalo"

And $ pod install

##Customization

###Number of Halos

Use haloLayerNumber property.

halo.haloLayerNumber = 3;

Or you can use initWithLayerNumber:.

PulsingHaloLayer *halo = [[PulsingHaloLayer alloc] initWithLayerNumber:3];
halo.position = self.view.center;
[self.view.layer addSublayer:halo];

###radius

Use radius property.

self.halo.radius = 240.0;
