小编Iva*_*sin的帖子

我正在尝试通过堆栈视图和 UIButtons 制作小数点的克隆。但是当我尝试在其中制作“Backspace”按钮图像时，它会缩放到按钮的边界。

如何使图像比例小于按钮本身？

我创造@IBAction了UIActivityViewController.

@IBAction func shareButton(_ sender: Any) {
        let text1 = "??????? ???????? ???? ? ?????????? \(year) ???."
        let text2 = "??????: \(mounthLabel.text!)"
        let text3 = "??????: \(weekLabel.text!)"
        let text4 = "???: \(dayLabel.text!)"
        let text5 = "????: \(hourLabel.text!)"
        let text6 = "??????: \(minuteLabel.text!)"
        let text7 = "???????: \(secundLabel.text!)"
        let URL0 = "??????? ????????? ??????? ?? ??????:"
        let URL = "https://itunes.apple.com/us/app/unit-converter/id1329406653?l=ru&ls=1&mt=8"
        let space = ""
        let space2 = ""


        let activityController = UIActivityViewController(activityItems: [text1, space, text2, text3, text4, …

如何在tableView中对单元格进行排序？

我有结构和数组:

struct Converter {
        let title: String
        let kf: Double
    }

    let converterAtmo = [
        Converter(title: "?????????", kf: 1),
        Converter(title: "????", kf: 365.2422),
        Converter(title: "??.??.??.", kf: 11.999998),
        Converter(title: "???????", kf: 525948.77),
        Converter(title: "????./??.????", kf: 52.177457)]

在CellAtRowfunc中:

let cell1 = tableView.dequeueReusableCell(withIdentifier: "resultCell") as! resultTableViewCell

            let item = converterAtmo[indexPath.row]

            cell1.nameResult.text = item.title
            cell1.labelResult.text = String(item.kf * atmosfera)


            return cell1

最后@IBAction:

 @IBAction func sortAlphabet(_ sender: Any) {

        let itemSort = converterAtmo

        itemSort.sorted { $0.title < $1.title }

        self.tableView2.reloadData() …

我正在尝试创建一个函数,当用户在UITextField中输入文本时,标签显示输入的文本.

我该怎么做？

喜欢:

textField.text = "10"

Label.text = "\(textField.text) smthg" //. (10 smthg)

textField.text = "10.56"

Label.text = "\(textField.text) smthg" //. (10.56 smthg)
