引脚移动后MKMapView刷新 [英] MKMapView refresh after pin moves

问题描述

使用新坐标更新自定义AnnotationView。但问题是它只能在用MKMapView进行一些操作之后进行视觉更新，例如：缩放或移动。
如何手动更新地图上的视觉位置？

A custom AnnotationView is updated with new coordinates. But the problem is that it visually updates only after some manipulations with MKMapView, e.g. zooming or moving. What should I do to manually update visual position on a map?

PS。我试图将区域更改为当前地图的区域。但它确实改变了变焦。这很奇怪。

PS. I've tried to change region to current map's region. But it does change zoom. It's strange.

[mapView setRegion:[mapView region] animated:YES];

推荐答案

经过数小时的研究后，我有点兴奋。答案就是：

I am a little shoked after hours of research. The answer is just:

[mapView setCenterCoordinate:mapView.region.center animated:NO];

不要问我为什么，但它更新了mapview，这就是我需要的。

Do not ask me why, but it updates a mapview and it's what i was need.
