CLLocationManager 的 AuthorizationStatus 在 iOS 14 上被弃用

Question

我使用此代码检查我是否有权访问用户位置

if CLLocationManager.locationServicesEnabled() {
    switch CLLocationManager.authorizationStatus() {
        case .restricted, .denied:
            hasPermission = false
        default:
            hasPermission = true
        }
    } else {
        print("Location services are not enabled")
    }
}

Xcode(12) 对我大吼大叫：

'authorizationStatus()' was deprecated in iOS 14.0

那么替代品是什么？

Answer 1

现在是 CLLocationManager、authorizationStatus 的属性。因此，创建一个 CLLocationManager 实例：

let manager = CLLocationManager()

然后您可以从那里访问属性：

switch manager.authorizationStatus {
case .restricted, .denied:
    ...
default:
    ...
}

iOS14 中有一些与位置相关的更改。请参阅 WWDC 2020 What's new in location。

不用说了，如果你还需要支持iOS 14之前的版本，那么只需添加#available检查，例如：

let authorizationStatus: CLAuthorizationStatus

if #available(iOS 14, *) {
    authorizationStatus = manager.authorizationStatus
} else {
    authorizationStatus = CLLocationManager.authorizationStatus()
}

switch authorizationStatus {
case .restricted, .denied:
    ...
default:
    ...
}

Objective C版本：

在Class界面

@property (nonatomic, strong) CLLocationManager *locationManager;

在Class代码

- (id) init {
self = [super init];
if (self != nil) {
    self.locationManager = [[CLLocationManager alloc]init];
}
return self;
}

-(CLLocation*)getLocation
{
    CLAuthorizationStatus status = [self.locationManager authorizationStatus];
    if (status == kCLAuthorizationStatusNotDetermined)
    {
        [self promptToEnableLocationServices];
        return nil;
    }
 etc...
