swift – Parse.com PFGeoPoint.geoPointForCurrentLocationInBa

问题是：从不调用参数列表中的块.这是我的代码：

PFGeoPoint.geoPointForCurrentLocationInBackground() {
    (point:PFGeoPoint!,error:NSError!) -> Void in

    NSLog("Test log 1") // Never printed

    if point != nil {
        // Succeeding in getting current location
        NSLog("Got current location successfully") // never printed
        PFUser.currentUser().setValue(point,forKey: "location")
        PFUser.currentUser().saveInBackground()
    } else {
        // Failed to get location
        NSLog("Failed to get current location") // never printed
    }
}

任何的想法？
