单击按钮UICollectionViewCell宽度和高度更改

Question

我有UIViewController，内部使用UICollectionViewController和单个按钮，我想在点击按钮时更改UICollectionViewControllerCell，如高度和宽度。

Answer 1

实现集合视图的委托

- (UICollectionViewTransitionLayout *)collectionView:(UICollectionView *)collectionView
                        transitionLayoutForOldLayout:(UICollectionViewLayout *)fromLayout
                                           newLayout:(UICollectionViewLayout *)toLayout

并在按钮上使用IBAction更改高度和宽度的值。

Answer 2

你可以尝试一次吗

[UIView transitionWithView:collectionView 
              duration:.5 
               options:UIViewAnimationOptionTransitionCurlUp 
            animations:^{

    //any animatable attribute here.
    cell.frame = CGRectMake(3, 14, 100, 100);
} completion:^(BOOL finished) {
  //whatever you want to do upon completion
}];
