百度地图IOS平台开发--自定义大头钉以及泡泡

来源:互联网 发布:淘宝的详情页图片尺寸 编辑:程序博客网 时间:2024/05/01 23:03

最近在做百度地图的相关开发,查阅了很多资料,包括csdn上的很多自定义视图方面的博客,因为和自己的地图设计要求不太一样,因此单独写了这篇博客,希望能给类似需求的同学一点帮助 ;

简单的说一下自定义视图的设计要求:

点击大头针的弹出泡泡视图中点击“选择”按钮,会触发两个变化:
1.按钮变成“取消选择” 
 2.对应的大头针图标上出现一个勾选的图片

草图如下:

下面开始正经地瞎说了(郭德纲的经典台词):

首先相信大家也大概知道MapView的基本属性和一些常用的代理方法,下面就挑我用到的几个属性和代理方法简单的

说明一下:

1 .属性:

(1)coordinate:这个属性是自带的,用来表示经纬度

(2)pointCalloutInfo:这个属性是自定义的,用来保存annotation的一些信息,诸如用户头像,用户名之类的

2.代理方法

(1)- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id<BMKAnnotation>)annotationnnotation;

   注意这个代理方法只要mapView addAnnotation一次就自动被调用一次

(2)- (void)mapView:(BMKMapView *)mapView didSelectAnnotationView:(BMKAnnotationView *)view

(3)- (void)mapView:(BMKMapView *)mapView didDeselectAnnotationView:(BMKAnnotationView *)view

         这里需要特别强调一下(2),(3)这两个代理方法的调用时序:

在我的这个项目里,是这样的。首先在viewDidLoad中初始化annotation,然后mapView addAnnotation,上面已说明,此时mapview立即调用(1)这个代理方法加载,那么此时我们就可以在mapview中看见大头钉,此时如果我们点击大头钉,就会调用方法(2),弹出大头钉对应的泡泡视图,接下来注意啦!!!如果我们紧接着点击大头钉是不会调用任何方法的,但如果我们紧接着点击的是泡泡视图,那么将先调用方法(3),然后再调用方法(2),有人问了,如果我们既不是点击大头钉和泡泡视图,而是点击地图空白处呢,那么很简单,系统会调用方法(3)。其实大家仔细琢磨一样,还是会想通的。


好吧,上面很啰嗦的说了很多,接下来进入主题,自定义视图。分为两部分,自定义大头钉和自定义泡泡视图

注意,上面提到的PinCell其实是一个UIView

       4.自定义泡泡视图

完全和上面的自定义大头针一样

至此,基本什么问题都解决了
