Google Map SDK 和 iOS，observeValueForKeyPath 问题

Question

我正在为 iOS 关注 Google MAP SDK Tutorial，几乎一切都很好，但是这个功能

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
        }
    }

"Method does not override any method from its superclass"

有什么想法吗？

谢谢

你能试试这个吗？更新了最新版本 Swift 的代码。看起来样本是基于 Swift.

的旧版本

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
    }
}
