CLLocationManager.requestLocation（）大约需要10秒钟 [英] CLLocationManager.requestLocation() takes about 10 seconds

问题描述

CLLocationManager.requestLocation（）大约需要10秒钟触发 didUpdateLocations 事件。

CLLocationManager.requestLocation() takes around 10 seconds to fire didUpdateLocations event.

这是为 CLLocationManager

let locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.distanceFilter = 10
locationManager.requestWhenInUseAuthorization()
locationManager.requestLocation()

根据文档，这可能需要几秒钟。

As per the documentation this can take several seconds.

此方法立即返回。调用它会导致位置管理器获取位置修复（可能需要几秒钟），并调用代理的locationManager（_：didUpdateLocations :)方法并返回结果。

This method returns immediately. Calling it causes the location manager to obtain a location fix (which may take several seconds) and call the delegate’s locationManager(_:didUpdateLocations:) method with the result.

但这可以花费10秒钟吗？还是我错过了什么？

But can this take 10 long seconds? Or am I missing something?

推荐答案

如果您退出

locationManager.requestLocation()

用于

locationManager.startUpdatingLocation() 

然后 didUpdateLocations 将立即开始触发。这应该可以解决您的问题。

then didUpdateLocations will start firing immediately. This should solve your problem.
