问题描述
我想在我的项目github here 中使用CalendarKit
它是使用UIKit编写的，但是我的项目使用SwiftUI。我可以在SwiftUI中使用call/1吗？ （也许通过let gpsServiceStatus = await Location.hasServicesEnabledAsync();
if (gpsServiceStatus) {
let location = await Location.getCurrentPositionAsync({ accuracy: Location.Accuracy.High });
this.setState({
userLat: location.coords.latitude,userLng: location.coords.longitude,navGeoStatus: true,lat: location.coords.latitude,lng: location.coords.longitude
});
} else {
alert("Enable Location services"); //or any code to handle if location service is disabled otherwise
}
还是其他方式？）

中没有什么有趣的东西。
感谢您的答复！
解决方法
大声笑，我不知道为什么以前没有奏效，但是如果您正在寻找类似的东西
public class ClassB : INotifyPropertyChanged
{
// stuff left out for brevity
public ClassB()
{
ClassAObject = new ClassA();
// Subscribe to ClassAObject's event and let subscribers of
// ClassB know that something changed
ClassAObject.PropertyChanged += (sender,eventArgs) =>
{
RaisePropertyChanged(nameof(Property_B));
};
}
}
