使用 ObjectiveC 的 Shapefile
我想知道 Objective-C 中是否有一个类可以操作 shapefile（读/写/编辑）？
我在 kml 文件上找到了很多东西，但没有找到有关 shp 文件的信息，但绝对希望避免转换文件格式的需要（shp-> kml）。
谢谢
I like to know if there is a Class, in objective-C, that manipulates shapefile (read/write/edit)?
I have found a bunch of stuff on kml files but nothing about shp files, but definitely want to avoid the need of converting files format (shp->kml).
Thanks

Pascal Brandt 有一个，...（有点简单，但对我来说确实有用）... CocoaShapeFile。他只是给 C 函数穿上了 Objective-C 的外衣，但它对于阅读来说效果很好。如果您使用 iOS 而不是 Cocoa 进行拍摄，那么您只需自己进行一些转码/转换即可。
只需一点点努力，我就能让它在 iPad 上运行，使用 MapKit，并使用引用计数而不是垃圾收集（在 iOS 上不可用）。
为了可能减轻你的痛苦（当然，我不知道你打算用 shapefile 做什么），但我发布了一个快速而肮脏的 git 存储库，iOS-Shapefile，向您展示如何将 shapefile 形状（如点和多边形/折线）获取到 iOS MKMapView 中。
至于写作和编辑（因为这超出了我的兴趣），我认为您可能必须采用自己的方法，偏离我在这里提供的方法。
There's one from Pascal Brandt, ... (it's a little simplistic, but it certainly does the trick for me) ... CocoaShapeFile. He's just dressed up the C functions in Objective-C clothes, but it works just fine for reading. If you're shooting for iOS instead of Cocoa then you'll have to do just a little transcoding/conversion yourself.
With only a little bit of effort, I was able to get it running on the iPad, using MapKit, and using reference counting instead of garbage collection (not available on iOS).
To potentially ease your pain a little (granted, I don't know what you plan to do with shapefiles), but I've released a quick and dirty git repository, iOS-Shapefile, that shows you how to get shapefile shapes (like points and polygons/polylines) into an iOS MKMapView.
As for writing and editing, (since that was beyond my interest), I think you'll likely have to roll your own methods, deviating from what I've provided here.
请参阅 Shapelib 库 它是用 C 编写的，但可以在 Objective-C 中使用，因为 OBJ-C 是一个超集C :)
See the Shapelib Libarary It's written in C, but is usable in Objective-C, as OBJ-C is a superset of C :)
