如何快速設置Mapbox地圖的間距？

Question

使用Mapbox非常新穎，並且有麻煩設置mapView的俯仰/方位。有什麼樣：

mapView.setPitch = 45 

任何幫助，不勝感激！

Answer 1

這是您可以做到的一種方法。

//Create a new MKMapCamera object 
var newCameraPosition = MGLMapCamera(lookingAtCenterCoordinate: mapView.centerCoordinate, fromDistance: mapView.camera.altitude + 1600, pitch: 50, heading: -30) 

// Then you could call it like this 
mapView.camera = newCameraPosition 

MapBox MGLMapCamera

但讓我解釋的設置。

@IBOutlet weak var mapView: MGLMapView! 

let distance: CLLocationDistance = 500 
let pitch: CGFloat = 35 
let heading = 45.0 
var camera = MGLMapCamera() 
let coordinate = CLLocationCoordinate2D(latitude: 49.7484405, 
             longitude: -132.9856644) 

override func viewDidLoad() { 
    super.viewDidLoad() 
    mapView.mapType = .Standard 

    camera = MGLMapCamera(lookingAtCenterCoordinate: coordinate, 
         fromDistance: distance, 
         pitch: 0, 
         heading: 0) 
    self.mapView.camera = camera 
} 

Answer 2

間距是MGLMapCamera類的一部分。

見

• https://github.com/mapbox/mapbox-gl-native/blob/ios-v3.3.4/platform/darwin/src/MGLMapCamera.h#L25
• https://www.mapbox.com/ios-sdk/api/3.3.4/Classes/MGLMapCamera.html#/c:objc(cs)MGLMapCamera(py)pitch

而這個示例代碼段

/** 
Pitch toward the horizon measured in degrees, with 0 degrees resulting in a 
two-dimensional map. 
*/ 

---

func togglePitch(sender: UISwitch) { 
    let camera = mapView!.camera 
    camera.pitch = sender.on ? 60 : 0 
    mapView!.setCamera(camera, animated: false) 
}
