📖 Getting started

Please run below command in your app in order to install cocoapods required by the library:

pod init

pod 'PXSiriWave', '~> 0.0.2'

💻 Usage

PXSiriWave *siriWave = [[PXSiriWave alloc] initWithFrame: CGRectMake(0, 0, 1000, 1000)];
siriWave.frequency = 1.5;
siriWave.amplitude = 0.01;
siriWave.intensity = 0.3;

siriWave.colors = [NSArray arrayWithObjects: [UIColor brownColor], [UIColor blueColor], [UIColor blackColor], nil];


[siriWave configure];

[self.view addSubview: siriWave];

Start Animation

Please setup Timer in order to animate waves:

    
    NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval: 0.10
    target:self
    selector: @selector(targetMethod:)
    userInfo: siriWave
    repeats:YES];

Set Timer Target


-(void)targetMethod:(NSTimer *)timer  {
    PXSiriWave *siriWave = [timer userInfo];
    
    [siriWave updateWithLevel: [self _normalizedPowerLevelFromDecibels: .1]];
}

- (CGFloat)_normalizedPowerLevelFromDecibels:(CGFloat)decibels {
    if (decibels < -60.0f || decibels == 0.0f) {
        return 0.0f;
    }
    
    return powf((powf(10.0f, 0.05f * decibels) - powf(10.0f, 0.05f * -60.0f)) * (1.0f / (1.0f - powf(10.0f, 0.05f * -60.0f))), 1.0f / 2.0f);
}

Stop Animation

[timer invalidate];
timer = NULL;
