如何在按钮触摸上更改UICollectionView框架

Question

我正在尝试关注代码但没有任何作用：

CGRect frame  = collectionview.frame;  
collectionview.frame = CGRectMake (frame.origin.x, frame.origin.y+100, frame.size, frame.size-100);

项目的AutoLayout设置为true。

Answer 1

尝试以下代码：

CGRect frame  = collectionview.frame;  
collectionview.frame = CGRectMake (frame.origin.x, frame.origin.y+100, frame.size.width, frame.size.height-100);

Answer 2

试试这个：

CGRect frame = collectionview.frame;
frame = CGRectMake (frame.origin.x, frame.origin.y+100, frame.size, frame.size-100);
collectionview.frame=frame;
