SWGradientNode is a subclass of SKSpriteNode that draws a sweep gradient around a center point with initial angle.

Place into Podfile pod 'SWGradientNode/ObjC' (ObjC-project) or pod 'SWGradientNode/Swift' (Swift-project).

Import #import <SWGradientNode/SWGradientNode.h> or import SWGradientNode.

This class is suitable for iOS and OSX.

Usage:

@implementation SmoothGradientScene

- (void)didMoveToView:(SKView *)view {
    [super didMoveToView:view];

    self.backgroundColor = [SKColor someColor];

    NSArray<SKColor *> *colors = ...; // some array of colors 

    SWGradientNode *node =
    [[SWGradientNode alloc] initWithColors:colors
                                 locations:nil // or other locations
                                    bounds:view.bounds
                              gradientType:SWGradientTypeSmooth];
    node.innerRadius = someValue;

    [self addChild:node];
}
@end

@implementation ViewController

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    SKView *skView = (SKView *)self.view;

    if (!skView.scene) {

    SmoothGradientScene *smoothGradientScene = [SmoothGradientScene sceneWithSize:skView.bounds.size];
    smoothGradientScene.scaleMode = SKSceneScaleModeAspectFill;

    [skView presentScene:smoothGradientScene];
    }
}

Length of locations array must be less by one than length of colors array.

Choose any of these types: SWGradientTypeSmooth, SWGradientTypeStep.

The center of sweeping gradient between (0.0, 0.0) and (1.0, 1.0). (0.0, 0.0) is a bottom left corner (OSX) or top left corner (iOS). (1.0, 1.0) is a top right (OSX) or bottom left corner (iOS). Default is (0.5, 0.5).

The first color of the gradient starts at initial angle in radians between 0 and 2*PI 0 is to the right along the x axis. All colors are located in counter-clockwise order. Default is 0.

The inner radius of the gradient Node will not draw any gradient inside circle with this radius Value between 0 and 0.5 Default is 0
