问题描述

我一直在研究CoreLocation。最近,我遇到了其他地方已经涉及的问题,但是在Objective C和iOS 8中。



我觉得有点傻问这个,但你怎么能检查一下在iOS 9上使用swift启用位置服务?



在iOS 7(可能是8?)上你可以使用 locationServicesEnabled(),但在编译iOS 9时似乎没有用。



那我该如何实现呢?



谢谢!

解决方案

添加 CLLocationManagerDelegate 你的班级继承,然后你可以进行这项检查:


Swift 1.x - 2.x版本:



'pre> 如果CLLocationManager.locationServicesEnabled(){
开关CLLocationManager.authorizationStatus(){
情况下.NotDetermined,.Restricted,.Denied:
打印(无法访问)
case .AuthorizedAlways,.AuthorizedWhenInUse:
print(Access)
}
} else {
print(位置服务未启用)
}

Swift 3.0版本:

 如果CLLocationManager.locationServicesEnabled(){
切换CLLocationManager。 authorizationStatus(){
情况下.notDetermined,.restricted,.denied:
打印( 无法访问)
情况下.authorizedAlways,.authorizedWhenInUse:
打印( 访问)
}
}其他{
打印(位置服务未启用)
}


I've been doing some research about CoreLocation. Recently, I encountered a problem that has been covered elsewhere, but in Objective C, and for iOS 8.

I feel kinda silly asking this, but how can you check if location services are enabled using swift, on iOS 9?

On iOS 7 (and maybe 8?) you could use locationServicesEnabled(), but that doesn't appear to be working when compiling for iOS 9.

So how would I accomplish this?

Thanks!

解决方案

Add the CLLocationManagerDelegate to your class inheritance and then you can make this check:

Swift 1.x - 2.x version:

if CLLocationManager.locationServicesEnabled() {
    switch CLLocationManager.authorizationStatus() {
    case .NotDetermined, .Restricted, .Denied:
        print("No access")
    case .AuthorizedAlways, .AuthorizedWhenInUse:
        print("Access")
    }
} else {
    print("Location services are not enabled")
}

Swift 3.0 version:

if CLLocationManager.locationServicesEnabled() {
     switch CLLocationManager.authorizationStatus() {
        case .notDetermined, .restricted, .denied:
            print("No access")
        case .authorizedAlways, .authorizedWhenInUse:
            print("Access")
        }
    } else {
        print("Location services are not enabled")
}
