调整集合视图单元格的屏幕尺寸

Question

This is the code I am using to setup my collection view.

- (void) setUpCollectionView {

UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];

[flowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal];

[flowLayout setMinimumInteritemSpacing:0.0f];

[flowLayout setMinimumLineSpacing:0.0f];

[flowLayout setItemSize:CGSizeMake(320, 566)];

[self.collectionView setPagingEnabled:YES];

[self.collectionView setCollectionViewLayout:flowLayout];

}

I am setting the item size of the flow layout to a set size. I want to know I can adjust this size for the current screen size the user is using. Thanks.

如果您的集合视图设置有约束以使其适应屏幕大小，则将单元格大小设置为与集合视图相同。

[flowLayout setItemSize:CGSizeMake(self.collectionView.frame.size.width, self.collectionView.frame.size.height)];
