MapKit：添加自定义标注 [英] MapKit : Add custom callout

问题描述

我想添加自定义annotationView标注，其中包含
1.标题
2.字幕
3.一个按钮

I want to add custom annotationView callout which contains 1. Title 2. subtitles 3. a button

按钮可以显示在右侧（ rightCalloutAccessoryView ）或左侧 leftCalloutAccessoryView 标注的两侧。我想在标注的中间添加按钮并在标题 - >副标题下添加。我该怎么办？

The button can display on the right (rightCalloutAccessoryView) or left leftCalloutAccessoryViewsides of the callout. I want to add the button in the middle of the callout and under title->subtitle. How can I do?

推荐答案

这里没有API。您可以尝试不使用标准callout（canShowCallout = NO），手动捕获AnnotationView上的点击和拖动，并通过基于AnnotationView的位置添加自定义视图来显示您自己的UI。但这似乎非常脆弱。

There is no API for this. You could try not using the standard callout (canShowCallout = NO), catch the taps and drags on the AnnotationView manually and show your own UI by adding custom Views based on the position of the AnnotationView. This seems very fragile, though.
