MapKit中的MapTypeStyle [英] MapTypeStyle in MapKit

问题描述

我想知道是否有任何方式配置我们的MapKit地图，就像我们在Google Maps API中的MapTypeStyle对象一样。

如果我提到苹果doc的MKMapView有一个mapType选项，它使用 MKMapType常量，但没有样式参数，如MapOptions， MapTypeStyle 和 MapTypeStyler 是非常强大的快速地图定制。

所以我的问题是：有没有办法实现类似于MapKit框架的东西，如果没有，什么是最好的框架/库做这个 ？我正在考虑 MapBox 和类似产品。

解决方案

我的朋友有几个选择您可以使用这些框架之一

或者你可以使用mapbox。他们的api看起来不错。
或者您可以为您提供自己的地图图块和重叠地图套件。 （MKMapRect）mapRect zoomScale：（MKZoomScale）zoomScale inContext :(（CGContextRef））（*）* ）context {

NSURL * fileURL = [（HeatMap *）self.overlay localUrlForStyle：@alienwithMapRect：mapRect andZoomScale：zoomScale];
NSData * imageData = [NSData dataWithContentsOfURL：fileURL];
if（imageData！= nil）{
UIImage * img = [UIImage imageNamed：@aTileX.png];
//在当前UI上下文执行图像渲染
UIGraphicsPushContext（context）;
[img drawInRect：[self rectForMapRect：mapRect] blendMode：kCGBlendModeNormal alpha：1.0];
UIGraphicsPopContext（）;
}
}

还要检查这个是否需要不支持的terrain模式

我实际上处于一个需要在地图上覆盖瓷砖的程序的中间。 此示例非常有用。你会想看看MKOverlay和MKOverlayView。我正在进行的项目涉及使用 gheat 。我正在通过NSURLConnection访问磁贴，并将其存储在本地。我实施的要点。

I wonder to know if there is any way to configure our MapKit maps like we do with the MapTypeStyle object in the Google Maps API.

If I refer to Apple doc's, MKMapView has a mapType option that takes MKMapType constant but no styles parameters like MapOptions with the MapTypeStyle and the MapTypeStyler wich is very powerfull for fast maps customizing.

So my question is : Is there any way to achieve something similar with the MapKit framework, if not, what is the best framework/library to do this ? I'm thinking of MapBox and similar products.

解决方案

There are a few options for you my friend. You could use one of these frameworks

Or you could just use mapbox. Their api looks pretty good. Alternatively you supply you own map tiles and overlay mapkit. Something like this in a MKOverlayView

- (void)drawMapRect:(MKMapRect)mapRect zoomScale:(MKZoomScale)zoomScale inContext:(CGContextRef)context {

NSURL* fileURL = [(HeatMap*)self.overlay localUrlForStyle:@"alien" withMapRect:mapRect andZoomScale:zoomScale];
NSData *imageData = [NSData dataWithContentsOfURL:fileURL ];
if (imageData != nil) {
    UIImage* img = [UIImage imageNamed:@"aTileX.png"];
    // Perform the image render on the current UI context
    UIGraphicsPushContext(context);
    [img drawInRect:[self rectForMapRect:mapRect] blendMode:kCGBlendModeNormal alpha:1.0];
    UIGraphicsPopContext();
    }
}

I'm actually in the middle of a program that requires overlaying tiles over a map. This example has been very helpful. You'll want to look into MKOverlay and MKOverlayView. The project that I am doing involves using gheat. I am accessing the tiles through an NSURLConnection and storing them locally. A gist of my implementation.
