旋转MKMapView的内容 [英] Rotate the content of a MKMapView

问题描述

我需要根据罗盘值旋转mapView的内容：

I need to rotate the content of the mapView according to the compass value:

float myHeadingValue = newHeading.trueHeading;

并且为了旋转地图我使用：

and for rotating the map I use this:

[mapView setTransform:CGAffineTransformMakeRotation( [self degreesToRadians:myHeadingValue] )];

但它会旋转视图，而不是视图的内容。

but it rotates the view, not the content of the view.

如何让它旋转内容，而不是整个视图？

How can I make it to rotate the content, not the whole view?

推荐答案

我是解决了它在Interface Builder中创建一个较小的UIView并将MKMapView放入其中。新的UIView没有显示剩余的地图。

I've solved it creating in Interface Builder a smaller UIView and putting the MKMapView into it. The new UIView does not show the leftover map.
