Question

我开发了一个谷歌地图，其中我正在显示atm附近的用户位置。我已经添加了一个活动指示器，用于在我的应用程序获取信息时设置动画，并且应该在获取信息时停止。

我已经编写了以下代码来执行此操作。我的活动指示器正在显示但不会被删除。请帮我这样做。

using System;
using System.Windows;
using System.Windows.Input;

namespace CommandsSample
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        #region NewFileCommand Handlers

        /// <summary>
        /// CanExecute
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void CouldCreateNewFile(object sender, CanExecuteRoutedEventArgs e)
        {
            e.CanExecute = !string.IsNullOrEmpty(FileText);
        }

        /// <summary>
        /// Executed
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void CreatenewFile(object sender, ExecutedRoutedEventArgs e)
        {
            FileText = string.Empty;
        }

        #endregion NewFileCommand Handlers

        #region Dependency Properties 

        /// <summary>
        /// The contents of the TextBox in the UI are backed by this property
        /// </summary>
        public String FileText
        {
            get { return (String)GetValue(FileTextProperty); }
            set { SetValue(FileTextProperty, value); }
        }

        // Using a DependencyProperty as the backing store for FileText.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty FileTextProperty =
            DependencyProperty.Register("FileText", typeof(String), typeof(MainWindow), new PropertyMetadata(string.Empty));


        #endregion Dependency Properties
    }
}

提前致谢。

在视图中更改didload在[self displayAtm];

中显示微调器之后最后调用此方法

- (void)viewDidLoad 
{
    [self startUserTracking];
   //  [self displayAtm];



spinner = [[UIActivityIndicatorView alloc]initWithFrame:CGRectMake(135,140,50,50)];
    spinner.color = [UIColor blueColor];
    [spinner startAnimating];
        [self.view addSubview:spinner];

[self displayAtm];

}

活动指标未从googlemap视图中删除
