BLBubbleFilters

BLBubbleFilters

BLBubbleFilters gives you bubble filters à la Apple Music.

Inspired by: SIFloatingCollection_Swift

Specs

  • SpriteKit
  • iOS 9+
  • tvOS 9+

Usage

The starting point of using BLBubbleFilters is the BLBubbleScene class. We begin by initialising one:

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    
    BLBubbleScene *scene = [BLBubbleScene sceneWithSize:CGSizeMake(self.view.bounds.size.width / 2.0, self.view.bounds.size.height / 2.0)];
    scene.backgroundColor = [UIColor whiteColor];
    scene.bubbleDataSource = <#code#>;
    scene.bubbleDelegate = <#code#>;

    [(SKView *)self.view presentScene:scene];
}

Notes:

  1. We highly recommend initialising a BLBubbleScene on viewWillAppear: so it gets correctly adjusted to the screen size.
  2. The example above assumes your view controller's view is a SKView.

Scene data source

You must provide the BLBubbleScene with a data source conforming to the BLBubbleSceneDataSource protocol. Its two required methods are:

//provides the scene with the number of bubbles to present
- (NSInteger)numberOfBubblesInBubbleScene:(BLBubbleScene *)scene {
    return <#code#>;
}

And:

- (id<BLBubbleModel>)bubbleScene:(BLBubbleScene *)scene
           modelForBubbleAtIndex:(NSInteger)index
{
    return <#code#>;
}

The BLBubbleModel protocol provides a bubble with some of the visual information it needs to draw itself.

Scene delegate

You may set the scene's delegate, if you'd like to be notified when a bubble is selected:

- (void)bubbleScene:(BLBubbleScene *)scene
    didSelectBubble:(BLBubbleNode *)bubble
            atIndex:(NSInteger)index
{
    //a bubble has been tapped
}

Example

A typical implementation of BLBubbleFilters looks like this:

#import "ViewController.h"
#import <BLBubbleFilters/BLBubbleFilters.h>
#import "Bubble.h"


@interface ViewController () <BLBubbleSceneDataSource, BLBubbleSceneDelegate>

@property (nonatomic, strong) NSArray<Bubble *> *bubbles;

@end


@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    [self setBubbles:@[[[Bubble alloc] initWithIndex:0],
                       [[Bubble alloc] initWithIndex:1],
                       [[Bubble alloc] initWithIndex:2],
                       [[Bubble alloc] initWithIndex:3]]];
}

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    
    BLBubbleScene *scene = [BLBubbleScene sceneWithSize:self.view.bounds.size];
    scene.backgroundColor = [UIColor whiteColor];
    scene.bubbleDataSource = self;
    scene.bubbleDelegate = self;

    [(SKView *)self.view presentScene:scene];
}

#pragma mark Bubble Delegate

- (void)bubbleScene:(BLBubbleScene *)scene
    didSelectBubble:(BLBubbleNode *)bubble
            atIndex:(NSInteger)index
{
    NSLog(@"Bubble Pressed! %@", bubble);
    NSLog(@"The bubble is now on state %ld", (long)[bubble.model bubbleState]);
}

#pragma mark Bubble Data Source

- (NSInteger)numberOfBubblesInBubbleScene:(BLBubbleScene *)scene
{
    return self.bubbles.count;
}

- (id<BLBubbleModel>)bubbleScene:(BLBubbleScene *)scene
           modelForBubbleAtIndex:(NSInteger)index
{
    return [self.bubbles objectAtIndex:index];
}

@end

Note: Implementation of the Bubble Data Model is up to you. ;)
