我正在开发一个嵌入了用mkmapkit制作的mapView的iPhone应用程序.我有两个坐标,我正在追踪这两点之间的方向.
一切都很好.我正在使用google maps api:maps.googleapis.com/maps/api/directions来检索xml以及方向的所有步骤.
但有一件事很奇怪:我只是无法理解为什么驾驶方向不准确.在两个步骤之间,它跟踪一条右线并且不沿着道路行走,而行走模式沿着道路追踪非常准确的方向.
驾驶模式: http ://www.michael-blin.fr/misc/aden/google/driving.png
步行模式: http ://www.michael-blin.fr/misc/aden/google/walking.png
我的问题很简单:你有没有使用谷歌地图api,你能理解为什么一个比另一个更准确...
我想解析一个复杂的CSV文件.我在网上搜索了一些来源,但我只找到了带有昏迷和引号的简单csv的读者.但我的还包含"{","["和":"以创建组,子组......
如何从这种csv中检索正确的NSArray或NSDictionary？或者你知道一个伟大的(伟大的!)csv阅读器/解析器？
谢谢 !
这是一个例子:
