點擊按鈕UICollectionViewCell寬度和高度變化

Question

我有UIViewController，內部使用UICollectionViewController和單鍵，我想要改變UICollectionViewControllerCell當點擊按鈕，如高度和寬度。

Answer 1

你可以試試這個曾經

[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 
}]; 

Answer 2

實現委託收集視圖

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

，並使用IBAction爲你的按鈕改變高度和寬度值。
