##Planned improvements:

• adding and removing thumbs during runtime.

I'll be glad to hear your requests

• CDCircle - is UIView subclass. It's, let's say, the base of a CDPieMenu. It's a circle drawn using CoreGraphics/QuartzCore.

• CDCircleThumb - UIView subclass, is a single segment in a CDPieMenu. It's subview of a CDCircle. Highly customisable. More information about modifying a thumb is listed below.

• CDIconView - UIImageView subclass, it handles colouring of an icon. CDIconView is subview of a CDCircleThumb.

• CDCircleOverlayView - this is independent view outside of the main view hierarchy. It handles selection of a thumb. It cannot be subview of a CDCircle because then, it would turn around with a circle.

###CDCircle

• -(id)initWithFrame:(CGRect) frame numberOfSegments:(NSUInteger) nSegments ringWidth:(CGFloat) ringWidth

####Delegate:

• -(void) circle:(CDCircle *)circle didMoveToSegment:(NSInteger)segment thumb:(CDCircleThumb *)thumb

####Data source:

• -(UIImage *) circle:(CDCircle *)circle iconForThumbAtRow:(NSInteger)row

###CDCircleOverlayView

• -(id) initWithCircle:(CDCircle) circle

###CDCircle:

• dataSource - data source of CDPieMenu.
• delegate - delegate of CDPieMenu
• (UIColor *) circleColor - Set this property to change color of a circle. It may be usable when you want to achieve specyfic effect (e.g. semi transparent thumbs, and coloured circle will create some effect)
• (NSArray *) thumbs - all thumbs.
• (CDCircleOverlayView *) overlayView - a pointer to CDCircleOverlayView
• (BOOL) inertiaEffect - it determines appearance of additional rotation after the last touch.

###CDCircleThumb:

• (CDIconView *)iconView - a pointer to thumb's CDIconView
• (UIColor *)separatorColor - color of a separator
• separatorStyle - it can be CDCircleThumbsSeparatorNone or CDCircleThumbsSeparatorBasic. Style of a separator.
• (BOOL)gradientFill - If gradientFill is set to NO, a thumb is coloured with solid color
• (NSArray *) gradientColors - colors of thumb's gradient.
• (NSArray *) colorsLocations - locations of colors in a gradient
• (UIColor *) arcColor - if gradientFill is set to 'NO' we can set thumb's color using this property.

###CDIconView:

• highlitedIconColor - color of an image when a thumb is selected

###CDCircleOverlayView:

• overlayThumb - pointer to a thumb which is the selector (central thumb)

Use this code to implement standard CDPieMenu:

 CDCircle *circle = [[CDCircle alloc] initWithFrame:CGRectMake(10 , 90, 300, 300) numberOfSegments:6 ringWidth:80.f];
circle.dataSource = self;
circle.delegate = self;
CDCircleOverlayView *overlay = [[CDCircleOverlayView alloc] initWithCircle:circle];
[self.view addSubview:circle];
//Overlay cannot be subview of a circle because then it would turn around with the circle
[self.view addSubview:overlay];

Code used to achieve effect shown above :

circle.overlayView.overlayThumb.arcColor = [UIColor colorWithRed:0.00f green:1.00f blue:0.25f alpha:0.4];

Code used to achieve effect shown above :

for (CDCircleThumb *thumb in circle.thumbs) {
[thumb.iconView setHighlitedIconColor:[UIColor redColor]];
 thumb.separatorColor = [UIColor whiteColor];
 thumb.separatorStyle = CDCircleThumbsSeparatorBasic;
 thumb.gradientFill = NO;
 thumb.arcColor = [UIColor greenColor];
 
  }

In order to use CDPieMenu add following frameworks to your project:

• CoreGraphics
• QuartzCore
