RateView - iOS (Objective-C)

RateView is a UIView subclass that creates a customizable rating view containing rating stars in it. It fills out the stars in percentage fill manner. It can be used for -

• displaying a rating for an item canRate = NO OR
• actually provide user a chance to rate any product or item canRate = YES.

Requirements

• iOS 6.0 or later.
• ARC enabled.

Installation

• Want a Pod for this, just add following line to your podfile-

pod 'RateView'

• You can directly copy the source files from RateView folder.

How To Use

Configuring RateView is as simple as :

RateView* rv = [RateView rateViewWithRating:3.7f];
[self.view addSubview:rv];

RateView takes it over from here.

• It uses CoreGraphics Context to draw the Star shapes with transparent background and appropriately percent fills them by calculating the rating.
• You should keep in mind to provide a rating between 0.0 to 5.0.
