最近开发中遇到个需求，自定义大头针，记录一下自己在开发的过程中遇到的问题和解决的思路，以供在以后的开发的过程中学习！
0.先看看效果
截屏2020-06-17 上午9.10.04.png
1.配置高德
这个不用详细介绍了吧，自己去官方文档配置下，超简单的，主要是pod几个库，
看你们的需求，需要什么导入什么我这边导入这两个:
#高德地图搜索
pod 'AMapSearch'
pod 'AMap3DMap'
2.显示地图 获取数据
- 懒加载地图显示出来
private lazy var mapView:MAMapView = {[unowned self] in
let mapView = MAMapView(frame: self.view.bounds)
mapView.delegate = self
mapView.showsUserLocation = true
mapView.userTrackingMode = .follow
mapView.isZoomEnabled = true
mapView.zoomLevel = 13
//显示比例尺 及位置
mapView.showsScale = true
mapView.scaleOrigin = CGPoint(x: WMRatio(20), y: WMRatio(100))
//设置自定义位置精度圈
mapView.customizeUserLocationAccuracyCircleRepresentation = true
return mapView
}()
- 添加到试图上 并且创建数据,这里有个问题，就是在我们点击的时候我需要获取到每个点击试图的所有信息，所以自己自定义一个myAnnotation继承至MAPointAnnotation，并且多帮他添加一个属性model，这样这里面就包含了你需要的所有数据，当点击的时候就可以拿到
for item in users {
let annation = myAnnotation()
let latDouble = item.lat?.doubleValue
let lngDouble = item.lng?.doubleValue
annation.coordinate = CLLocationCoordinate2D(latitude: latDouble! , longitude: lngDouble!)
annation.model = item
self.arr.append(annation)
}
mapView.addAnnotations(arr)
3.实现地图代理方法
- 写这里的时候有个问题就是定位位置，但不展示自身定位的大头针，我开始本来不想去代理方法里面去设置空图片解决，当时用过这个方法 就是在创建大头针数据的时候，移除掉自身定位的大头针数据，再展示，但是并没有什么卵用，具体不知道是什么原因？有了解的可以在下方评论，一起学习，谢谢！
在创建完数据的时候用这个去移除自身定位的大头针的数据，没有作用
mapView.removeAnnotation(self.mapView.userLocation)
最终还是在代理方法中去设置自身定位的图片为空的实现的（本来我是拒绝的....）
func mapView(_ mapView: MAMapView!, viewFor annotation: MAAnnotation!) -> MAAnnotationView! {
if annotation.isKind(of: MAUserLocation.self) {
//去掉定位的图片
let identifier = "item1"
var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier)
if annotationView == nil {
annotationView = MAPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
}
annotationView?.image = UIImage(named: "")
return annotationView
}
if annotation.isKind(of: MAPointAnnotation.self) {
//自定义一个大头针的数据
let identifier = "item"
var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier) as? WMDreamSquareViewController.DreamMapView.customAnnotationView
if annotationView == nil {
annotationView = customAnnotationView(annotation: annotation, reuseIdentifier: identifier)
}
annotationView?.annotation = annotation// 重要
annotationView?.canShowCallout = false// 设置弹框
let ata = annotation as? WMDreamSquareViewController.myAnnotation
annotationView?.dataModel = ata?.model
return annotationView
}
return nil
}
//MARK:大头针点击事件
func mapView(_ mapView: MAMapView!, didSelect view: MAAnnotationView!)
{
mapView.deselectAnnotation(view.annotation, animated: true)
let ata = view.annotation as? WMDreamSquareViewController.myAnnotation
self.didAnnationViewBlock!(ata!.model!)
}
//MARK:缩放回调 用于刷新数据，因为不可能一次性在界面上请求所有数据，所以我想了下叫后台接收一个我返回的距离给他 主要计算的方式是在指定的缩放级别下, 基于地图中心点, 1 screen point 对应的距离(单位是米)*屏幕的宽度
func mapView(_ mapView: MAMapView!, mapDidZoomByUser wasUserAction: Bool) {
let unit = CGFloat(mapView.metersPerPoint(forZoomLevel: mapView.zoomLevel)) * iphone.width
print("2=======\(mapView.zoomLevel)============\(CGFloat(mapView.metersPerPoint(forZoomLevel: mapView.zoomLevel)))--\(iphone.width)----\(unit)")
self.touchZoomRefreshBlock!(Int(ceil(unit)))
}
4.自定义大头针试图
- 自定义一个大头针的试图
//MARK:继承MAAnnotationView来创建一个自己的大头针视图
class customAnnotationView:MAAnnotationView {
private lazy var bgImageView:UIImageView = {
let view = UIImageView()
view.contentMode = .scaleAspectFit
view.image = UIImage(named: "椭圆45")
view.isUserInteractionEnabled = true
return view
}()
private lazy var headView:UIImageView = {
let view = UIImageView()
view.layer.cornerRadius = WMRatio(17.5)
view.layer.masksToBounds = true
view.backgroundColor = UIColor.clear
return view
}()
var dataModel: WMDreamSquareViewController.User?{
didSet {
guard let dataModel = dataModel else {
return
}
bgImageView.image = (dataModel.type?.stringValue == "1") ? UIImage(named: "xygc_tx_bg_r") : UIImage(named: "xygc_tx_bg_y")
headView.yy_setImage(with: URL(string: dataModel.avatar_url!.stringValue), placeholder: UIImage(named: "face"))
}
}
override init!(annotation: MAAnnotation!, reuseIdentifier: String!) {
super.init(annotation: annotation, reuseIdentifier: reuseIdentifier)
//这里需要设置一个大小要不然点击响应不了
self.bounds = CGRect(x: 0, y: 0, width: WMRatio(45), height: WMRatio(45))
addSubview(bgImageView)
bgImageView.addSubview(headView)
bgImageView.layoutSubviews()
bgImageView.snp.makeConstraints { (make) in
make.centerX.centerY.equalToSuperview()
make.width.height.equalTo(WMRatio(45))
}
headView.snp.makeConstraints { (make) in
make.centerX.equalToSuperview()
make.centerY.equalTo(bgImageView).offset(-WMRatio(3))
make.width.height.equalTo(WMRatio(35))
}
}
override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
let rect = self.convert(self.frame, from: self.superview)
//print("point---------\(point)========rect------\(rect)*********self.frame------\(self.frame)")
if rect.contains(point) {
return self
}else{
return nil
}
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
5.扩展 还需要实现一个弹出的试图

6.总结
在这个过程中遇到的两个问题1.就是关掉自身的大头针，除了去代理方法中设置空图片，我试了好多中其他的方式都实现不了2.点击大头针试图传值。开始没有想到继承，直接用系统的，一直带不过来数据，后面还想着用title做对比得到数据中的索引，但是这样做感觉太麻烦了，有点得不偿失！
