Question

我遇到了UICollectionViewCell的问题，对我这样的新手来说真的很难。我需要你的帮助。我正在写一本字典。我有一个搜索栏，一个集合视图，一些标签和一个文本视图。但是在显示搜索结果时，我无法调整集合视图单元格和文本视图的大小。

查看控制器：

import UIKit

class sozlukController: UIViewController, UISearchBarDelegate, UICollectionViewDataSource, UICollectionViewDelegate{
    @IBOutlet var wordSearchBar: UISearchBar!
    @IBOutlet var collection: UICollectionView!
    var wordDataList = [String]()
    var meaningDataList = [String]()
    var dictionaryDataList = [String]()
    var yearDataList = [String]()

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    func searchBarSearchButtonClicked(searchBar: UISearchBar)  {
        wordDataList = []
        meaningDataList = []
        dictionaryDataList = []
        yearDataList = []
        var word = searchBar.text
        var parser:dictXMLParser = dictXMLParser()
        var searchResults:[dictXMLResponse]=parser.beginParsing(1, searchType: 1, searchWord: word)

        for result in searchResults {
            wordDataList.append(result.word)
            meaningDataList.append(result.meaning)
            dictionaryDataList.append(result.dictionary)
            yearDataList.append(result.year)
        }
        searchBar.resignFirstResponder()
        searchBar.text=""
         collection.reloadData()

    }



    func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return wordDataList.count
    }

    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell:meaningCollectionViewCell = collectionView.dequeueReusableCellWithReuseIdentifier("Cell", forIndexPath: indexPath) as! meaningCollectionViewCell
        cell.wordLabel.text = wordDataList[indexPath.row]
        cell.meaningText.text = meaningDataList[indexPath.row]
        cell.dictionaryLabel.text = dictionaryDataList[indexPath.row]
        return cell
    }


}

UICollectionViewCell：

import UIKit

class meaningCollectionViewCell: UICollectionViewCell , UITextViewDelegate{
    @IBOutlet var wordLabel: UILabel!
    @IBOutlet var meaningText: UITextView!
    @IBOutlet var dictionaryLabel: UILabel!

    override func  layoutSubviews() {
        super.layoutSubviews()
        let fixedWidth = meaningText.frame.size.width
        let newSize = meaningText.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.max))
        meaningText.frame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)

    }

}

当我写＆＃34; gamze＆＃34;在＆＃34;第一个＆＃34;的搜索栏中时间，因为文本视图高度，我没有看到整个意思。

令人惊讶的是，当我为第二次搜索编写相同的单词时，文本视图高度增加，并且它覆盖了以下标签。但是由于UICollectionViewCell高度，我再也看不到整个意义。

Screenshot of second search

我设置了可滚动的＆＃34; false＆＃34;和自动布局＆＃34; on＆＃34;通过界面构建器。有没有一种方法可以显示textview中的含义，它不包含任何标签，并根据其内容调整大小集合视图单元格

我无法找到有关swift的消息来源。如果你能提供帮助，我会非常感激。

我在github上找到了一个很棒的解决方案。诀窍是为单元格内容创建xib文件
