Google Map SDK和iOS，观察ValueForKeyPath问题

Question

我正在关注适用于iOS的Google MAP SDK 教程 ，几乎一切都很好，但是此功能

override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject, change: [String : AnyObject], context: UnsafeMutablePointer<Void>) {
        if !didFindMyLocation {
            let myLocation: CLLocation = change[NSKeyValueChangeNewKey] as! CLLocation
            viewMap.camera = GMSCameraPosition.cameraWithTarget(myLocation.coordinate, zoom: 10.0)
            viewMap.settings.myLocationButton = true

            didFindMyLocation = true
        }
    }

“方法不会覆盖其超类中的任何方法”

Xcode 7 Swift 2 Google Map iOS SDK

任何想法？

谢谢

你可以试试这个吗？ 更新了最新版本的Swift的代码。 看起来该示例基于旧版本的Swift。

override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
    if !didFindMyLocation {
        let myLocation: CLLocation = change![NSKeyValueChangeNewKey] as! CLLocation
        viewMap.camera = GMSCameraPosition.cameraWithTarget(myLocation.coordinate, zoom: 10.0)
        viewMap.settings.myLocationButton = true

        didFindMyLocation = true
    }
}
