如何在MKMapview上绘制自定义线? [英] How to draw custom line on MKMapview?

问题描述

我一直在寻找一种绘制自定义线条的方法，但是我唯一能找到的帮助就是如何使用UIColor绘制线条.

I've been searching for a way to draw a custom line, but the only help I can find is how to draw lines with an UIColor.

我想画一条直线，而不仅仅是用一种颜色.我希望该行的外观可自定义.

I want to draw a straight line but not just with a color. I want the appearance of the line to be customizable.

(所以现在我可以在2点之间画线，但不能画我想要的线)

(So right now I can draw lines between 2 points, but not the line I want)

我要的直线上有45度直线，它是灰色和黑色.

The line I want got straight 45 degree lines on it, and it's grey and black.

有人可以帮忙吗?

这条线看起来像这样，我也在想我可以拉伸该图像，但是如果拉伸它，它将看起来有点奇怪.

The line looks like this, I'm also thinking that I could stretch this image, but if I stretch it, it will look kinda weird.

推荐答案

听起来像您想要的是 MKOverlayPathView ，您可以设置笔触和填充颜色.

Sound like what your looking for is the MKPolylineView Class. You assign it a polyline which contains the points in your line. Since the polyline view is an MKOverlayPathView you can set the stroke and fill colors.

由于它也是UIView子类，因此您可以通过获取views图层属性并添加渐变，阴影，遮罩等来进一步操纵外观.

Since it's also a UIView subclass you can manipulate the appearance even further by grabing the views layer property and adding gradients, shadows, masks, etc.

您要达到的特定效果吗?

Is there a specific effect that you're trying to achieve?
