c# - MonoTouch Multiple Mapkit CLLocationCoordinate2D 与自定义 PIN 图像
<p><p>您好，我的主要问题是如何使用 <code>MKAnnotationView</code> 为我的所有坐标点设置自定义图钉图像。 </p>
<p>作为引用，我已经继续硬编码了我通常会从 json webservice 调用中调用的值。
下面是硬编码路径的示例:</p>
<pre><code>CLLocationCoordinate2D[] trail1 = new CLLocationCoordinate2D[]{
new CLLocationCoordinate2D(10.74812, -97.330277),
new CLLocationCoordinate2D(10.74501, -97.350277),
new CLLocationCoordinate2D(10.74912, -97.340277),
};
CLLocationCoordinate2D[] trail2 = new CLLocationCoordinate2D[]{
new CLLocationCoordinate2D(10.84812, -97.331277),
new CLLocationCoordinate2D(10.94501, -97.352277),
new CLLocationCoordinate2D(10.14912, -97.343277),
new CLLocationCoordinate2D(10.12912, -97.313277),
};
mapview.AddAnnotation (new SampleMapAnnotation (trail1));
</code></pre>
<p>现在我正在使用 <code>MKAnnotation</code>，但意识到我需要使用 <code>MKAnnotationView</code> 来自定义图像引脚。</p>
<pre><code>public class SampleMapAnnotation : MKAnnotation
{
string _title;
public SampleMapAnnotation (CLLocationCoordinate2D coordinate)
{
Coordinate = coordinate;
_title = "Sample";
}
public override CLLocationCoordinate2D Coordinate { get; set; }
public override string Title
{
get {
return _title;
}
}
}
</code></pre></p>
