Removes the need to copy-paste stanzas from other files anymore as we'll rely on #4478 to generate the correct stanza for us instead.

Shadow elevations
A shadow elevation specifies the degree of shadow intensity to be displayed beneath an object. Higher shadow elevations have greater shadow intensities, akin to raising an object above a surface resulting in a more prominent, albeit more diffuse, shadow. This component provides commonly used Material Design elevations for components.

pod 'MaterialComponents/ShadowElevations'
Then, run the following command:
pod install
Usage
Importing
Before using Shadow Elevations, you'll need to import it:
Swift
import MaterialComponents
class ShadowedView: UIView {
override class var layerClass: AnyClass {
return MDCShadowLayer.self
}
var shadowLayer: MDCShadowLayer {
return self.layer as! MDCShadowLayer
}
func setDefaultElevation() {
self.shadowLayer.elevation = .cardResting
}
}
Objective-C
#import "MaterialShadowElevations.h"
@interface ShadowedView: UIView
@end
@implementation ShadowedView
+ (Class)layerClass {
return [MDCShadowLayer class];
}
- (MDCShadowLayer *)shadowLayer {
return (MDCShadowLayer *)self.layer;
}
- (void)setDefaultElevation {
self.shadowLayer.elevation = MDCShadowElevationCardResting;
}
@end
