MKAnnotationView和MKPinAnnotationView的区别

之前一直没搞清楚MKAnnotationView和MKPinAnnotationView的区别，看apple的官方文档终于搞清楚了。

如果想创建以静态图片作为大头针图片的话，可以通过创建MKAnnotationView是实例。如果想使用apple自带的大头针则创建MKPinAnnotationView

If the annotation can be represented by a static image, create an instance of the

MKAnnotationView

class and assign the image to its

image

property; see
“Using the Standard Annotation Views.”

If you want to use a standard pin annotation, create an instance of the

MKPinAnnotationView

class; see
“Using the Standard Annotation Views.”
