deferredLocationUpdatesAvailable在iOS 10中返回NO [英] deferredLocationUpdatesAvailable returns NO in iOS 10

问题描述

我正在尝试使用一些CoreLocation功能，并且我遇到了延迟位置更新的问题。

I am trying to use some CoreLocation features, and I am running into problems with deferred location updates.

出于某种原因，为iOS 10更新了应用程序deferredLocationUpdatesAvailable总是返回NO。我在iPhone 6s上测试，所以我知道该设备能够使用GPS功能。

For some reason when the app was updated for iOS 10 deferredLocationUpdatesAvailable returns NO always. I am testing on an iPhone 6s, so I know that the device is capable of using GPS features.

我尝试使用它来调试：

[CLLocationManager deferredLocationUpdatesAvailable]

我无法弄清楚这是iOS 10的问题，还是我设置错误。

I can't figure out if this is an issue with iOS 10 or if I have something set incorrectly.

在这种方法中：

- (void)locationManager:(CLLocationManager *)manager didFinishDeferredUpdatesWithError:(NSError *)error {
    self.deferringUpdates = NO;
    NSLog(@"DEFERRING Error: [%@]", error);
    if (error) {
        [[LocationManagerClient alertWithMessage:error.localizedDescription andTitle:error.domain] show];
    }
}

我最终记录了这个错误：

I end up logging this error:

DEFERRING Error: [Error Domain=kCLErrorDomain Code=11 "(null)"]

有没有其他人遇到iOS 10这个问题或者知道发生了什么？

Has anyone else run into this problem with iOS 10 or have any idea what is going on?

编辑：
这就是我设置距离过滤器的方法

This is how I am setting the distance filter

- (void)configureForApplicationWillResignActive {
    [_locationManager setAllowsBackgroundLocationUpdates:YES];
    [_locationManager setPausesLocationUpdatesAutomatically:NO];
    [_locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
    [_locationManager setDistanceFilter:kCLDistanceFilterNone];   // use distance filter
    [_locationManager requestAlwaysAuthorization];
}

- (void)configureForApplicationDidBecomeActive {
    [_locationManager setAllowsBackgroundLocationUpdates:YES];
    [_locationManager setPausesLocationUpdatesAutomatically:NO];
    [_locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
    [_locationManager setDistanceFilter:kCLDistanceFilterNone];   // use distance filter
    [_locationManager requestAlwaysAuthorization];
}

推荐答案

我已经提交了雷达（28303779）带有概念验证示例代码 - 还包含雷达的措辞。我还打开了一个开发论坛帖子，看来很多工程师都面临同样的问题问题。 deferredLocationUpdatesAvailable（）在iOS 10中也返回false。似乎苹果故意关闭了该功能。

I have already filed a Radar (28303779) with proof of concept sample code - also contains the wording from the radar. I have also opened a dev forum post and it appears a lot of engineers are facing the same problem. deferredLocationUpdatesAvailable() is also returning false in iOS 10. Seems like apple has intentionally turned off the functionality.

更新

我的错误报告已关闭，说'它按预期工作'。我想苹果公司并不打算解决这个问题，并且在没有弃用的情况下错误地将其取出。

My Bug Report got closed saying 'it works as intended'. I suppose Apple does not intend to fix it and it was mistakenly taken out without deprecation first.
