Mkmapview a custom Pin

How to customize a pin

--Set the agent for Mkmapview

Implement the following proxy method, which returns the Pin control

-(Mkannotationview *) Mapview: ( Mkmapview *) Mapview viewforannotation: (id< mkannotation >) annotation;

Create and return the corresponding PIN control based on the passed in (ID < mkannotation >) annotation parameter

Use of Proxy methods note

If nil is returned, the displayed pin takes the system's default style

A blue glowing dot that identifies the user's location, which is also a pin, and when the pin is displayed, the proxy method is also called

Therefore, you need to be clear in the Proxy method (ID < mkannotation >) annotation parameter represents a custom pin or a blue glow dot
