Question

我创建了一个包含UIView的集合视图单元，并且在UIView内有一个按钮。我想做的是单击按钮时将更改UIView边框颜色。然后，我从服务器加载数据并将其显示在集合视图中。

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CypherCollectionViewCell", for: indexPath as IndexPath) as! CypherCollectionViewCell

    cell.tickButton.addTarget(self, action: #selector(tickButtonClicked(sender:)), for: .touchUpInside)

    return cell
}

@objc func tickButtonClicked( sender: UIButton) {
    if sender.isSelected {
        sender.isSelected = false
        // To change the UIView border color
    } else {
       sender.isSelected = true
       // To change the UIView border color
    }
}

谢谢！

您可以将按钮点转换为视点并获得所需的单元格。

static func changeButtonStyle(fullString: NSString, boldPartsOfString: String, changeFontString: String) -> NSAttributedString {
    let nonBoldFontAttribute = [
        NSFontAttributeName: MyFont.caption2,
        NSForegroundColorAttributeName: MyColor.white
    ]

    /* convert NSString to be added as NSMutableAttributedString */
    let changeThemeString = NSMutableAttributedString(string: fullString as String, attributes: nonBoldFontAttribute)

    if boldPartsOfString.count > 0 {
        let boldFontAttribute = [NSFontAttributeName: MyFont.subheading]
        changeThemeString.addAttributes(boldFontAttribute, range: fullString.range(of: boldPartsOfString))
    }

    if changeFontString.count > 0 {
        let colorFontAttribute = [NSForegroundColorAttributeName: MyColor.darkPink]
        changeThemeString.addAttributes(colorFontAttribute, range: fullString.range(of: changeFontString))
    }

    return changeThemeString
}
