swift - Parse.com PFGeoPoint.geoPointForCurrentLocationInBackground 没有做任何事情

Question

我正在使用 Parse.com iOS SDK，我需要用户的当前位置，所以我正在使用函数 PFGeoPoint.geoPointForCurrentLocationInBackground(...) .

问题是:参数列表中的 block 从未被调用。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
    }
}

有什么想法吗？

我遇到了同样的问题。它已在 Parse 1.4.0 中修复。

您还需要将以下键/值对添加到您应用的 info.plist 中:

<key>NSLocationWhenInUseUsageDescription</key>
<string>We want to send your location data to the NSA, please allow access to location services. (replace this text with whatever you want the dialog to say)</string>

• CLLocationManager in iOS 8 - use of NSLocationWhenInUseUsageDescription
