首先例子是小编写的一个定位获取经纬度，然后在地图上面显示，并自定义大头针的一个程序。先上图

首先说一下定位，在 iOS 8 之前，位置服务的权限是二元的：你要么赋予一个应用得到使用位置服务的权限，要么不给。你可以在 Settings.app 查看哪些 app 可以在后台取得你的位置信息，但除了完全不让这个 app 使用位置服务之外，你不能做任何的事来阻止它获取位置信息，但是在IOS8之后, 修改了这个问题，ISO8把应用程序分成两个权限，

“使用期间”  正如标题，程序在使用期间会获取你的位置信息。
“始终”   这个就跟IOS8之前一样，会在程序中一直获取你的个人信息。

所以我们在使用地图的时候，要在Info.plist里面添加两行文字，设置我们程序使用地图的权限。

NSLocationWhenInUseUsageDescription  //用的时候获取位置

NSLocationAlwaysUsageDescription    //始终获取用户位置

首先就是先把CoreLocation框架引入过来。直接晒代码吧。懒得写了。代码下面注释

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController,MKMapViewDelegate,CLLocationManagerDelegate {
    @IBOutlet weak var mapView: MKMapView!
    var locationManger:CLLocationManager = CLLocationManager()
    var location:CLLocation!
    var ann:MKPointAnnotation = MKPointAnnotation()
    override func viewDidLoad() {
        super.viewDidLoad()
        
        locationManger.delegate = self
        locationManger.desiredAccuracy = kCLLocationAccuracyBest
        locationManger.distanceFilter = kCLLocationAccuracyKilometer
        
        locationManger.requestAlwaysAuthorization()
        locationManger.startUpdatingLocation()
        
        mapView.delegate = self
        mapView.mapType = MKMapType.Satellite
        
        ann.title = "定位的位置"
        ann.subtitle = "广州"
        
        mapView.addAnnotation(ann)
        
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    
    /**
    
    重写 - 更改大头针颜色
    :param: mapView
    :param: annotation
    
    :returns: MKAnnotationView
    */
    func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView!
    {
        var view:MKPinAnnotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "pin")
        view.pinColor = MKPinAnnotationColor.Red
        //view.image = UIImage(named: "localtion.png")
        var viewLeft = UIView(frame: CGRectMake(0, 0, 50, 50))
        viewLeft.backgroundColor = UIColor.redColor()
        var viewRight = UIView(frame: CGRectMake(0, 0, 50, 50))
        viewRight.backgroundColor = UIColor.greenColor()
        view.leftCalloutAccessoryView = viewLeft
        view.rightCalloutAccessoryView = viewRight
        view.draggable = true
        view.canShowCallout = true
        return view
    }
    
   
    
    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
        location = locations.last as! CLLocation
        if((location) == nil) {
            locationManger.startUpdatingLocation()
        }
        println("\(location.coordinate.longitude)")
        mapView.region = MKCoordinateRegion(center: CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude), span: MKCoordinateSpanMake(20, 20))
        ann.coordinate = CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude)
    }

}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) { }

        locationManger.delegate = self
        locationManger.desiredAccuracy = kCLLocationAccuracyBest
        locationManger.distanceFilter = kCLLocationAccuracyKilometer
        
        locationManger.requestAlwaysAuthorization()
        locationManger.startUpdatingLocation()

然后到了设置地图地方了。添加地图的代理，设置大头针的主标题和副标题。

mapView.delegate = self
        mapView.mapType = MKMapType.Satellite
        
        ann.title = "定位的位置"
        ann.subtitle = "广州"
        
        mapView.addAnnotation(ann)

func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView!
    {
        var view:MKPinAnnotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "pin")
        view.pinColor = MKPinAnnotationColor.Red
        //view.image = UIImage(named: "localtion.png")
        var viewLeft = UIView(frame: CGRectMake(0, 0, 50, 50))
        viewLeft.backgroundColor = UIColor.redColor()
        var viewRight = UIView(frame: CGRectMake(0, 0, 50, 50))
        viewRight.backgroundColor = UIColor.greenColor()
        view.leftCalloutAccessoryView = viewLeft
        view.rightCalloutAccessoryView = viewRight
        view.draggable = true
        view.canShowCallout = true
        return view
    }

location = locations.last as! CLLocation
        if((location) == nil) {
            locationManger.startUpdatingLocation()
        }
        println("\(location.coordinate.longitude)")
        mapView.region = MKCoordinateRegion(center: CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude), span: MKCoordinateSpanMake(20, 20))
        ann.coordinate = CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude)
    }

然后看下一个。

地图覆盖层

简单来说就是在地图地图上面画图。

首先是在地图上面画线

        var coor = [CLLocationCoordinate2D]()
        for (var i=0; i<5; i++) {
         po = CLLocationCoordinate2DMake(CLLocationDegrees(23 + i), 113)
            coor.append(po)
        }
        var line = MKPolyline(coordinates: &coor, count: 5)
        mapView.addOverlay(line)

这里有一个犯错点，var line =MKPolyline(coordinates: &coor, count:5)  。

 MKPolyline(coordinates: <#UnsafeMutablePointer<CLLocationCoordinate2D>#>, count: <#Int#>)

然后添加 MKMapViewDelegate 代理，实现代理的方法。

func mapView(mapView: MKMapView!, rendererForOverlay overlay: MKOverlay!) -> MKOverlayRenderer! {
        var render = MKPolylineRenderer(overlay: overlay)
        render.lineWidth = 3
        render.strokeColor = UIColor.redColor()
        return render
        
    }
