MKAnnotationView仅旋转“图像"属性 [英] MKAnnotationView Only Rotate the Image property

问题描述

我有一个MKAnnotationView，我只想旋转image属性.

I have an MKAnnotationView where I want to rotate the image property only.

如果我使用以下内容...

If I use the following...

        self.image= image;
        [self setTransform:CGAffineTransformMakeRotation(DEG2RAD([item.heading floatValue]))];

它旋转整个我不希望看到的注解视图和后续的标注.有没有一种方法可以旋转图像属性?

It rotates the whole annotationView and the subsequent callouts which I do not want. Is there a way to just rotate the image property?

推荐答案

最简单的方法可能是将图像放在UIImageView中，并将其作为子视图添加到MKAnnotationView中，然后进行仿射.

The simplest way is probably to put the image in a UIImageView, add that as a subview to the MKAnnotationView, and affine that.

如果您的目标是iOS 5.0，则可以查看

If you are targeting iOS 5.0 you could look at CIAffineTransform but I don't know enough about CoreImage to advise.
