如何在swift 3 IOS中使用UITextField实现以下屏幕。

Answer 1

这样做......

为左侧图标图像添加getInfosUser(maxRetries = 2): Observable<Response> { return this.authHttp.get(this.apiUrl+'getuserinfos') .map((response: Response) => { return response; }) .catch((error: any) => { if ( (error.status === 401 || error.status === "401") && maxRetries > 0 ) { return Observable.fromPromise(this.authService.handleError(error)).concat(getInfosUser(maxRetries - 1)); } else { return Observable.throw( new Error(error.status) ); } }) }，设置所需图像和背景颜色
在imageview旁边添加UIImageView，并在界面构建器（故事板）中将边框样式设置为“无边框样式”
设置所需的背景颜色
也为密码字段执行相同操作，对于眼睛图标视图，请查看此https://github.com/Sahilberi/ImageTextField

Answer 2

添加 UITextField
将子视图添加为 imageView
设置 UITextField的Alpha

下面的示例代码：

private void MasterCheck()
{
    this.pnlProgress.Visibility = System.Windows.Visibility.Visible;

    //I'm using progress bar functionality in ReturnMasters method
    Thread myNewThread = new Thread(() => Auditor.AuditMasterSlides(Globals.ThisAddIn.Application.ActivePresentation, this.pnlMaster, this, token));

    token = new CancellationTokenSource();
    myNewThread.Start();
    this.pnlProgress.Visibility = System.Windows.Visibility.Collapsed;
}

public static void AuditMasterSlides(PPT.Presentation pres, Panel panel, MainProofingTaskPaneControl control, CancellationTokenSource cancToken)
{
    IDictionary<string,MasterSlide> masterSlides = ReturnMasters(pres, cancToken, control);
    control.ShowAndCollapse(panel);
    control.RemovePanelChildren(panel);

    if (masterSlides.Count>1)
    {
        //control.AddControlToPanel(panel, new MasterCheckControlOK());
    }
    else
    {
        control.AddControlToPanel(panel, new MasterCheckControlOK());
    }
}

internal void RemovePanelChildren(Panel panel)
{
    this.Dispatcher.Invoke(() =>
    {
        for (int i = panel.Children.Count - 1; i >= 0; i--)
        {
            panel.Children.RemoveAt(i);
        }
    });
}

internal void AddControlToPanel(Panel panel, Control control)
{
    MasterCheckControlOK newControl = new MasterCheckControlOK();

    this.Dispatcher.Invoke(() =>
    {
        panel.Children.Add(newControl);
    });
}

导入UIKit

类ViewController：UIViewController {

@IBOutlet weak var txtpassword: UITextField!
@IBOutlet weak var txtUserName: UITextField!
@IBOutlet weak var txtView: UITextView! //your textView


override func viewDidLoad() {

    super.viewDidLoad()
    //navigationBarColor()
    setTextFieldSpace( textField :txtUserName)
    setTextFieldSpace( textField :txtpassword)
    //textField border
    txtpassword.borderStyle = .none
    txtUserName.borderStyle = .none

}

//MARK: - Button Action
// password show hide
@IBAction func btnShowPasswordClick(_ sender: UIButton) {
    if txtpassword.isSecureTextEntry{
        txtpassword.isSecureTextEntry = false
    }else{
        txtpassword.isSecureTextEntry = true
    }
}

//for set space in left side of textField
func setTextFieldSpace( textField :UITextField){
    let lblSpace = UILabel()
    lblSpace.frame = CGRect.init(x: 0, y: 0, width: 5, height: 5)
    lblSpace.backgroundColor = .clear
    textField.leftView = lblSpace

    textField.leftViewMode = .always
    textField.contentVerticalAlignment =  .center
}

}
