如何使MKMapView
的背景颜色变暗, NOT 同时使MKOverlay
的{{1}}变暗 - 类似到Nike + app的地图视图。

好的,我在这里得到了解决方案,在向地图添加其他叠加层之前,您可以将总叠加层添加为地图的背景,因此地图的背景颜色会发生变化,但叠加层仍然像之前一样,这是代码
MKMapRect worldRect = MKMapRectWorld;
MKMapPoint point1 = MKMapRectWorld.origin;
MKMapPoint point2 = MKMapPointMake(point1.x+worldRect.size.width,point1.y);
MKMapPoint point3 = MKMapPointMake(point2.x, point2.y+worldRect.size.height);
MKMapPoint point4 = MKMapPointMake(point1.x, point3.y);
MKMapPoint points[4] = {point1,point2,point3,point4};
self.polygon = [MKPolygon polygonWithPoints:points count:4];
[self.runMapView addOverlay:self.polygon];

Swift 2.0
let worldRect = MKMapRectWorld
let point1 = MKMapRectWorld.origin
let point2 = MKMapPointMake(point1.x + worldRect.size.width, point1.y)
let point3 = MKMapPointMake(point2.x, point2.y + worldRect.size.height)
let point4 = MKMapPointMake(point1.x, point3.y)
var points = [point1, point2, point3, point4]
let polygon = MKPolygon(points: &points, count: points.count)
mapView.addOverlay(polygon)
