    rect.addCoordinate(CLLocationCoordinate2D(latitude: -86.41212, longitude: 32.49626)) 
    rect.addCoordinate(CLLocationCoordinate2D(latitude: -86.41197, longitude: 32.49065)) 
    rect.addCoordinate(CLLocationCoordinate2D(latitude: -86.41197, longitude: 32.48577)) 
    rect.addCoordinate(CLLocationCoordinate2D(latitude: -86.41187, longitude: 32.48112)) 

    // Create the polygon, and assign it to the map. 
    let polygon = GMSPolygon(path: rect) 
    polygon.fillColor = UIColor(red: 0.25, green: 0, blue: 0, alpha: 0.05); 
    polygon.strokeColor = UIColor.blackColor() 
    polygon.strokeWidth = 2 
    polygon.map = mapView 
}

}

這似乎並不繪製polyglon。難道我做錯了什麼？

查看您的經緯度值。您在完全不同的位置繪製多邊形。（並且您的源多邊形中的值不正確）

let camera = GMSCameraPosition.cameraWithLatitude(37.0902, longitude: -95.7129, zoom: 3.0) 

rect.addCoordinate(CLLocationCoordinate2D(latitude: -86.41182, longitude: -32.4757))

您的代碼似乎正確。

謝謝。這解決了我的問題。我們可以添加標記到多邊形嗎？ – dang

不是。你可以在多邊形裏面添加一個標記，你應該用下面這樣的東西來計算你的多邊形的中心：http://stackoverflow.com/questions/16850332/how-to-calculate-the-center-coordinates-of-cllocationdistance – derdida
