我正试图把pdf或UIImage作为地图。 是否有办法将纬度和长度纳入pdf,这样一来,即可在该档案中显示目前的位置?
我知道如何在洞.图中显示目前的位置。 但是,我完全不知道如何用pdf或UIImage取代它。

你们需要了解你们形象的界限,以及它与全球定位系统的关系。 例如,如果你的形象显示纬33度至34度,长度——112度至113度,那么你就能够在此范围内绘制地图。 你们也需要知道,你们的形象是多么大,让你们假设1000x1000。
因此,如果你在3,325、112.25之间进行协调,那么你在图像中的地位将是250,750。
地图的实际变化
destX = (destMaxX - destMinX) * (sourceX / (sourceMaxX - sourceMinX));
例如,
destMaxX = 1000;
destMinX = 0;
sourceX = 33.25;
sourceMaxX = 34;
sourceMinX = 33;
Same接着是Y,在你见到的Y处就座。
希望能让你们走上正轨。
Tim说,你是如何集中和认识到像地图一样的形象的,但记住要打上<代码>。 显示UserLocation=YES
