objective-c - Objective-C : Error when trying to initialize instance of CLLocation

Question

当遇到以下代码时，我遇到了错误(程序崩溃)

CLLocation *userLoc = [[CLLocation alloc] initWithCoordinate:locationManager.location.coordinate];

我尝试用以下内容替换参数，但我也遇到了同样的错误

CLLocation *userLoc = [[CLLocation alloc] initWithCoordinate:mapView.userLocation.coordinate];

谁能告诉我应该在此处为用户当前位置使用的正确参数是什么？

谢谢!

Answer 1

根据documentation , CLLocation 没有名为 initWithCoordinate: 的初始化程序。使用以下之一:

• initWithLatitude:经度:
• initWithCoordinate:altitude:horizo​​ntalAccuracy:verticalAccuracy:timestamp:
• initWithCoordinate:altitude:horizo​​ntalAccuracy:verticalAccuracy:course:speed:timestamp:
