About

BFRadialWaveView is a sublcass of UIView. It displays a radial wave with various options. It was made to be the progress/spinner view for BFRadialWaveHUD.

Changes

Please refer to this CHANGELOG.md.

To do:

  • Restart animations on app wake-up.
  • Move resources into a resource directory, reflecting this change in the cocoapod. (Fix file structure)

Modes

BFRadialWaveViewMode_Default       // Default: A swirly looking thing.
BFRadialWaveViewMode_KuneKune      // Kune Kune: A creepy feeler looking thing.
BFRadialWaveViewMode_North         // North: Points upwards.
BFRadialWaveViewMode_NorthEast     // North East: Points upwards to the right.
BFRadialWaveViewMode_East          // East: Points right.
BFRadialWaveViewMode_SouthEast     // South East: Points downwards to the right.
BFRadialWaveViewMode_South         // South: Points down.
BFRadialWaveViewMode_SouthWest     // South West: Points downwards to the left.
BFRadialWaveViewMode_West          // West: Points left.
BFRadialWaveViewMode_NorthWest     // North West: Points at Kanye.

Methods

Initializer

Use this when you make a BFRadialWaveView in code.

/**
 *  Custom initializer. Use this when you make a BFRadialWaveView in code.
 *
 *  @param container       A UIView to place this one in.
 *  @param numberOfCircles NSInteger number of circles. Min = 3, Max = 20.
 *  @param circleColor     UIColor to set the circles' strokeColor to.
 *  @param mode            BFRadialWaveViewMode.
 *  @param strokeWidth     CGFloat stroke width of the circles.
 *  @param withGradient    BOOL flag to decide whether or not to draw a gradient in the background.
 *
 *  @return Returns A BFRadialWaveView! Aww yiss!
 */
- (instancetype)initWithView:(UIView *)container
                     circles:(NSInteger)numberOfCircles
                       color:(UIColor *)circleColor
                        mode:(BFRadialWaveViewMode)mode
                 strokeWidth:(CGFloat)strokeWidth
                withGradient:(BOOL)withGradient;

Setup

Use this when you made a BFRadialWaveView in the storyboard or xib

/**
 *  Setup. Use this when you made a BFRadialWaveView in the storyboard or xib.
 *
 *  @param container       A UIView to place this one in.
 *  @param numberOfCircles NSInteger number of circles. Min = 3, Max = 20.
 *  @param circleColor     UIColor to set the circles' strokeColor to.
 *  @param mode            BFRadialWaveViewMode.
 *  @param strokeWidth     CGFloat stroke width of the circles.
 *  @param withGradient    BOOL flag to decide whether or not to draw a gradient in the background.
 */
- (void)setupWithView:(UIView *)container

                color:(UIColor *)circleColor
                 mode:(BFRadialWaveViewMode)mode
          strokeWidth:(CGFloat)strokeWidth
         withGradient:(BOOL)withGradient;

Loading

/** Show a basic view with no progress. */
- (void)show;

Progress

/**
 *  Show a view with progress.
 *
 *  @param progress CGFloat between 0.f and 1.f. The progress to show.
 */
- (void)showProgress:(CGFloat)progress;

Success

/** Show a success view. */
- (void)showSuccess;

Error

/** Show an error view. */
- (void)showError;

Update

/**
 *  Update the progress to a certain value.
 *
 *  @param progress CGFloat between 0.f and 1.f. The progress to show.
 */
- (void)updateProgress:(CGFloat)progress;
/**
 *  Update the circle color on the fly.
 *
 *  @param color UIColor to set the circles' strokeColor to.
 */
- (void)updateCircleColor:(UIColor *)color;

Pause and Resume

Pause and Resume features graciously added by GitHub user @fco-edno :)

/** Pause the animation. */
- (void)pauseAnimation;

/** Resume the animation. */
- (void)resumeAnimation;

/**
 *  Check the paused/not-paused state of the view's animations.
 *
 *  @return Returns a BOOL flag indicating the state of the animation being either paused (YES) or not-paused (NO).
 */
- (BOOL)isPaused;

Fun

/**
 *  Activate of Deactivate disco mode! This will rapidly cycle colors through your BFRadialWaveView. Without setting the colors explicitly, a rainbow is used.
 *
 *  @param on BOOL flag to turn disco mode on (YES) or off (NO).
 */
- (void)disco:(BOOL)on;

Properties

/** The diameter of the view (including progress circle). */
@property (nonatomic, readonly) CGFloat diameter;

/** The UIColor to set the progress circle to. Default is the same as the circleColor passed into the initializer or the setup. */
@property (nonatomic) UIColor *progressCircleColor;

/** The UIColor to set the success checkmark to. By default it is the same as the circleColor passed into the initializer or the setup. */
@property (nonatomic) UIColor *checkmarkColor;

/** The UIColor to set the failure cross to. By default it is the same as the circleColor passed into the initializer or the setup. */
@property (nonatomic) UIColor *crossColor;

/** An NSArray of colors to use for disco mode. By default it is the rainbow. */
@property (nonatomic) NSArray *discoColors;

/** CGFloat speed for the disco animation. Default is 0.33f. */
@property (nonatomic) CGFloat discoSpeed;

/** BFRadialWaveViewDelegate delegate for our protocol. */
@property id <BFRadialWaveViewDelegate> delegate;

Usage

Be sure the check out the included demo app to see examples on how to use BFRadialWaveView.

Add the BFRadialWaveView header and implementation files to your project. (BFRadialWaveView.h & BFRadialWaveView.m) as well as the BFGradientCALayer header and implementation files to your project. (BFGradientLayer.h & BFGradientLayer.m)

Working Example

BFRadialWaveView *radialWaveView;
radialWaveView = [[BFRadialWaveView alloc] initWithView:self.view
                                                circles:BFRadialWaveView_DefaultNumberOfCircles
                                                  color:nil
                                                   mode:BFRadialWaveViewMode_Default
                                            strokeWidth:BFRadialWaveView_DefaultStrokeWidth
                                           withGradient:YES];
[radialWaveView show];

Customized Example

BFRadialWaveView *radialWaveView;
radialWaveView = [[BFRadialWaveView alloc] initWithView:self.view
                                                circles:10
                                                  color:[UIColor darkGray]
                                                   mode:BFRadialWaveViewMode_North
                                            strokeWidth:5.f
                                           withGradient:NO];
[radialWaveView disco:YES];   // Disco time!
[radialWaveView showProgress:someProgressBetweenZeroAndOne];
