ios - 编辑 CollectionViewCell 的宽度
<p><p>我正在尝试编辑单元格的宽度,以便无论屏幕大小如何,我都会连续有 <code>score1.count</code> 个单元格。我用于收藏 View 的代码如下:</p>
<pre><code>func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return self.items.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath as IndexPath) as! MyCollectionViewCell
cell.myLabel.text = String(self.items)
return cell
}
</code></pre>
<p>这是针对单元格宽度的函数。</p>
<pre><code>func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout,sizeForItemAt indexPath: IndexPath) -> CGSize {
let size = Int(self.view.frame.size.width)/(score1.count + 1)
return CGSize(width: CGFloat(size), height: 80)
}
</code></pre>
<p>我花了很多时间查看不同的来源并尝试不同的东西,但 Collection View 从来没有正确数量的单元格。一个想法是,这可能是因为我在自动布局中设置了单元格大小,但是每当我去更改它时,xcode 就会崩溃。关于绕过自动布局的任何想法?或者如何改变自动布局?</p>
<p>谢谢!</p></p>

<p><p>试试这个<br/></p>
<pre><code>extension YourViewController : UICollectionViewDelegateFlowLayout{
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
let rowItems:CGFloat = 4
let padding:CGFloat = 2
let width = (collectionView.bounds.width / rowItems) - padding //Change width as per your requirement
let height = collectionView.bounds.height - (2 * padding)//Change height as per your requirement
return CGSize(width: width, height: height)
}
}
</code></pre></p>
