离子3 -ios 11-始终要求GPS位置

Question

对于iPhone上的最新iOS版本，我不会始终在iPhone上跟踪您的位置。我会在应用程序上，从来没有。但是，此功能似乎对以前的每个版本都可以正常工作。除了我在下面的Xcode中所做的任何其他建议都将很棒。

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.");
        }

在PLIST文件中

 <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>

Answer 1

代码具有逻辑倒置，应该是：

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.");
}

注意我切换了这两条线：

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

您可以参考主源代码。

此外，对于iOS 11，当请求始终许可时，您应将NSLocationAlwaysAndWhenInUseUsageDescription和NSLocationWhenInUseUsageDescription密钥包括在您的信息plist中。

<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>

您必须在应用程序的info.plist文件中包含NSLocationWheninUseusagedEsagedEscription和NslocationalSagideScription和NslocationalSevelways和wheninuseusateDescription键。（如果您的应用程序支持iOS 10及更早，则还需要NSlocationalwaysingescription键。）如果不存在这些键，则授权请求立即失败。
