如何在iphone中获取gmsmapview的坐标中心 [英] How to get coordinate center of gmsmapview in iphone

问题描述

我正在使用适用于iOS的新版Google Maps SDK

I'm using the new Google Maps SDK for iOS

我可以从GMSMapView.center获取真正的坐标吗？
现在它返回一个CGPoint值，但它不是真正的坐标。

Can I get the true coordinate form GMSMapView.center? Now it returns a value of CGPoint, but it's not the true coordinate.

感谢和问候。

推荐答案

我建议使用 [yourMapView.camera target] 而不是Jing的解决方案。

I suggest to use [yourMapView.camera target] instead of Jing's solution.

Jing的解决方案在iOS 6上运行正常，但可能在iOS 7 / 7.1上有问题，
投影可能报告错误的坐标（有点向下移位）！
我检查了地图边界和填充是否正确，结果是 [projection pointForCoordinate：coordinate] 和 [projection coordinateForPoint：point] 可以相互对比，没有问题在哪里......

Jing's solution work fine on iOS 6, but maybe having issue on iOS 7/7.1, the projection may report wrong coordinate (a bit downward shift) ! I have checked the map bounds and padding is correct, both result of [projection pointForCoordinate: coordinate] and [projection coordinateForPoint:point] can contrast to each other, no ideas where the problem is...
