Question

对于iPhone上的最新ios版本，我没有得到“永远不会”的＃i;始终在iPhone上跟踪您的位置。我在应用程序上得到的时间永远不会。但是，此功能似乎适用于以前的每个版本。除了我在下面的XCode中所做的任何其他建议都会很棒。

CDVLocation.m

if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationAlwaysUsageDescription"]){
            [self.locationManager requestWhenInUseAuthorization];
        } else if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationWhenInUseUsageDescription"]) {
            [self.locationManager  requestAlwaysAuthorization];
        } else {
            NSLog(@"[Warning] No NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key is defined in the Info.plist file.");
        }

plist文件中的

 <key>NSLocationAlwaysUsageDescription</key>
    <string>This app requires constant access to your location in order to track your position, even when the screen is off.</string>

代码的逻辑是反转的，应该是这样的：

if ([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationAlwaysUsageDescription"]){
    [self.locationManager  requestAlwaysAuthorization];
} else if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationWhenInUseUsageDescription"]) {
    [self.locationManager requestWhenInUseAuthorization];
} else {
    NSLog(@"[Warning] No NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key is defined in the Info.plist file.");
}

注意我切换了这两行：

[self.locationManager  requestAlwaysAuthorization];
[self.locationManager requestWhenInUseAuthorization];

您可以参考主人source code。

此外，对于iOS 11，requesting always permission时，您应在信息plist中加入NSLocationAlwaysAndWhenInUseUsageDescription和NSLocationWhenInUseUsageDescription键。

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
    <string>When always is requested in iOS 11</string>
<key>NSLocationWhenInUseUsageDescription</key>
    <string>When "when in use" is requested in iOS 11</string>

您需要在应用的Info.plist文件中包含NSLocationWhenInUseUsageDescription和NSLocationAlwaysAndWhenInUseUsageDescription键。（如果您的应用支持iOS 10及更早版本，则还需要NSLocationAlwaysUsageDescription键。）如果这些键不存在，则授权请求会立即失败。
