DSGraphicsKit

Utilities for common and advanced graphics operations.

DSGraphicsKit provides support to quickly perform the following operations:

• Images:
  • Create icons with fills, glows and shadows from the alpha channel of an image.
  • Resize with corner rounding.
  • Render a layer to an image.
• Views:
  • Add a 3d rotation along the y axis.
  • Add a reflection.
• Animations:
  • Add a pop up animation to a layer.

Installation

Use CocoaPods:

pod 'DSGraphicsKit'

Usage

Rotating and adding a reflection to a view:

UIView *view;
[view setYRotation:25.0f];
[view addReflectionToSuperLayer];

Icons:

UIImage *source;
UIImage *fill;
UIColor *color1;
UIColor *color2;

UIImage *icon0 = [source gradientIconWithRGBColors:[NSArray arrayWithObjects:color1, color2, nil]];
UIImage *icon1 = [fill applyAlphaFromImage:source glowWidth:5.0f offset:CGSizeZero color:color1];
UIImage *icon2 = [source iconWithForeground:fill background:[UIColor colorWithWhite:0.1 alpha:1.0] radius:4.0];

Images resizing with corners rounding:

UIImage *original;
UIImage *new = [original imageResizedToSize:CGSizeMake(160, 160)
                           withCornerRadius:24.0f
                                    corners:DSCornerTopLeft | DSCornerBottomRight
                               transparency:NO];

Animations:

UIView *view;
[view.layer addPopUpAnimation];
