问题描述
我正在努力使用mapbox(ios/swift)setVisibleCoordinateBounds函数来将地图的视口居中到给定的BoundsCoords. 在此处查看api
i'm struggleing with the mapbox (ios/swift) setVisibleCoordinateBounds function to center the viewport of a map to the given BoundsCoords. see api here
当我调用函数时，它从不设置确切的范围，也没有设置更具体的缩放级别.给定的boundsCoords是正确的.还尝试了setCenterCoordinate:zoomLevel:direction:animated:completionHandler，因为我需要一个completionHandler.但是它有山姆的问题.有人遇到过类似的问题吗?
It never set the exact Bounds or more specific it sets diffrent zoom levels whenever i call the function. the given boundsCoords are correct. Also tried setCenterCoordinate:zoomLevel:direction:animated:completionHandler cause i need an completionHandler. But it has the sam issues. Somebody experienced similar issues ?
推荐答案
使用一种允许您自定义边缘填充的方法，例如: -[MGLMapView setVisibleCoordinates:count:edgePadding:direction:duration:animationTimingFunction:completionHandler:] .
Use one of the methods that allows you to customize the edge padding, such as: -[MGLMapView setVisibleCoordinates:count:edgePadding:direction:duration:animationTimingFunction:completionHandler:].
如果不需要任何填充，请将edgePadding设置为UIEdgeInsetsZero.
Set edgePadding to UIEdgeInsetsZero, if you don’t need any padding.
在即将发布的v3.3.0中，将会有一个 -[MGLMapView cameraThatFitsCoordinateBounds:edgePadding:] 方法.
In the upcoming v3.3.0, there will be a -[MGLMapView cameraThatFitsCoordinateBounds:edgePadding:] method, as well.
