我在使用 Objective Sharpie 进行绑定时遇到了一些问题。我正在将IndoorAtlas
iOS 本机 sdk 与 Xamarin.ios 绑定。
问题是在实现协议方法时,因为这些方法没有被调用。我们需要特殊处理吗?
我正在附加 API 定义文件和实现文件。
// @protocol IALocationManagerDelegate
[Protocol, Model]
[BaseType(typeof(NSObject))]
interface IALocationManagerDelegate
{
// @optional -(void)indoorLocationManager:(IALocationManager *
_Nonnull)manager didUpdateLocations:(NSArray * _Nonnull)locations;
[Export("indoorLocationManager:didUpdateLocations:")]
void DidUpdateLocations(IALocationManager manager, IALocation[] locations);
// @optional -(void)indoorLocationManager:(IALocationManager *
_Nonnull)manager didEnterRegion:(IARegion * _Nonnull)region;
[Export("indoorLocationManager:didEnterRegion:")]
void DidEnterRegion(IALocationManager manager, IARegion region);
}
// @interface IALocationManager : NSObject
[BaseType(typeof(NSObject))]
interface IALocationManager
{
[Wrap("WeakDelegate")]
[NullAllowed]
IALocationManagerDelegate Delegate { get; set; }
// @property (readwrite, nonatomic, weak) id<IALocationManagerDelegate>
_Nullable delegate;
[NullAllowed, Export("delegate", ArgumentSemantic.Weak)]
NSObject WeakDelegate { get; set; }
}
////ViewController --调用委托方法
[Export("indoorLocationManager:didUpdateLocations:")]
public void DidUpdateLocations(IALocationManager manager , IALocation[] locations)
{
IALocation loc = locations[locations.Length - 1];
if (mFloorPlan != null)
{
CoreGraphics.CGPoint cg = mFloorPlan.CoordinateToPoint(loc.Location.Coordinate);
this.map.Center = cg;
}
}
[Export("indoorLocationManager:didEnterRegion:")]
public void DidEnterRegion(IALocationManager manager, IARegion region)
{
if (region.Type != ia_region_type.FloorPlan)
Console.WriteLine("Region Changed to {0} " + region.Identifier);
else
{
FetchFloorPlan();
}
}
