Usage
Importing
Before using Collection Layout Attributes, you'll need to import it:
Objective-C
#import "MaterialCollectionLayoutAttributes.h"
Swift
import MaterialComponents.MaterialCollectionLayoutAttributes
The MDCCollectionViewLayoutAttributes class allows passing properties to a cell from a collection
view layout. Override the -applyLayoutAttributes method of any UICollectionReusableView or
UICollectionViewCell subclasses, then apply any of the properties of the attributes class.
Objective-C
- (void)applyLayoutAttributes:(UICollectionViewLayoutAttributes *)layoutAttributes {
[super applyLayoutAttributes:layoutAttributes];
if ([layoutAttributes isKindOfClass:[MDCCollectionViewLayoutAttributes class]]) {
MDCCollectionViewLayoutAttributes *attr = (MDCCollectionViewLayoutAttributes *)layoutAttributes;
if (attr.representedElementCategory == UICollectionElementCategoryCell) {
// Example to set a background image to the cell background view.
self.backgroundView = [[UIImageView alloc] initWithImage:attr.backgroundImage];
}
}
}
Swift
override func applyLayoutAttributes(layoutAttributes: UICollectionViewLayoutAttributes) {
super.applyLayoutAttributes(layoutAttributes)
if let attr = layoutAttributes as? MDCCollectionViewLayoutAttributes {
if (attr.representedElementCategory == .Cell) {
// Example to set a background image to the cell background view.
self.backgroundView = UIImageView(image: attr.backgroundImage)
}
}
}
