Ios 编码器出错

您好，我正在我的

ios

应用程序中使用

GoogleMaps

，我必须在

CoreData

中保存地图标记位置。我正在使用代码

GMSMarker *marker = [GMSMarker markerWithPosition:position];
marker.map = _mapView;
[waypoints_ addObject:marker];
NSDictionary *routeDict = [[NSDictionary alloc] initWithObjectsAndKeys:
                           waypoints_ ?: [NSNull null], routeName,
                           nil];
id delegate = [[UIApplication sharedApplication] delegate];
self.managedObjectContext = [delegate managedObjectContext];
NSManagedObjectContext *context = [self managedObjectContext];
Route *routeInfo = [NSEntityDescription
                      insertNewObjectForEntityForName:@"Route"
                      inManagedObjectContext:context];
routeInfo.routeName = routeName;
routeInfo.wayPoints = routeDict;

但该应用程序在保存到核心数据时崩溃。 我有个例外

-[GMSMarker encodeWithCoder:]: unrecognized selector sent to instance 0xac72940
2014-05-14 12:31:50.053 Routes[4087:a0b] *** -[NSKeyedArchiver dealloc]: warning:      NSKeyedArchiver deallocated without having had -finishEncoding called on it.
2014-05-14 12:31:50.057 Routes[4087:a0b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[GMSMarker encodeWithCoder:]: unrecognized selector sent to instance 0xac72940'

GMSMarker

不响应

encodeWithCoder:

，因此无法将其放入随后将被编码的词典中（这是在核心数据中将词典设置为属性时发生的情况）

您应该只在核心数据中存储基础数据航路点，然后在请求时从该航路点重建UI
