我使用客观尖锐的绑定几乎没有问题。我是绑定的 IndoorAtlas
ios ios ios native sdk与xamarin.ios。
问题是在实施协议方法时,因为没有调用这些方法。我们需要以特殊的方式处理它吗?
我正在附加API限定文件和实现文件。
// @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 -calling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();
}
}
不要忘记将ViewController分配给弱委托。
IALocationManager manager = new IALocationManager();
manager.WeakDelegate = this;
