Swift 如何仅获取当前位置坐标,如果;“允许一次”;迅速地
我在info.plist中添加了三个权限 弹出窗口有三个选项。。这里 1) 如果我在使用应用程序时单击“允许”,则我需要用当前位置地址自动填充文本字段,但Swift 如何仅获取当前位置坐标,如果;“允许一次”;迅速地,swift,mkmapview,Swift,Mkmapview,我在info.plist中添加了三个权限 弹出窗口有三个选项。。这里 1) 如果我在使用应用程序时单击“允许”,则我需要用当前位置地址自动填充文本字段,但 如果单击“允许一次”,则不需要用当前位置自动填充文本字段 在“我的代码”中的“允许一次”和“使用时允许”条件中,文本字段自动填充当前位置地址: class MapViewController: UIViewController, CLLocationManagerDelegate { let locationManager = CLLoc

case .denied:
print("User hates you!!")
case .authorizedWhenInUse:
let viewController = self.storyboard?.instantiateViewController(withIdentifier: "FinalViewController") as! FinalViewController
self.navigationController?.pushViewController(viewController, animated: true);
case .authorizedAlways:
let viewController = self.storyboard?.instantiateViewController(withIdentifier: "FinalViewController") as! FinalViewController
self.navigationController?.pushViewController(viewController, animated: true);
}
}
}
实际上,当我单击“允许一次”时,我只需要当前位置坐标,不需要在文本字段中自动填充地址。怎么做
请提供代码帮助。
在使用时
和允许一次
是相同的权限,但有效期不同。点击位置权限提示上的允许一次
,将在使用时启用应用程序当前会话的权限,即,直到用户强制终止应用程序或应用程序长时间处于后台。如果用户点击一次Allow
权限,您将获得所有位置更新,就像他在使用时给予权限一样。但如果用户终止应用程序并重新启动,系统将再次显示位置权限提示
因此,通过检查locationManager(\uManager:CLLocationManager,didChangeAuthorization
返回的状态,您无法尝试执行的操作,因为它将为这两个权限提供authorizedWhenInUse
状态。您无法区分它们
有没有办法这样做……或者没有……请给我一些建议
