シンプルなベジエ曲線エディターを構築しようとしています。以下のモデルとコード。node.bcpInDataまたはnode.bcpOutDataを削除しようとすると、 node.originDataのみが削除されます。魔女はまったく意味がありません。
これは私のモデルです：
delete:メソッドは次のとおりです。
-(void) delete:(id)sender {
[undoManager beginUndoGrouping];
[points willChangeValueForKey:@"arrangedObjects"];
NSMutableArray * nodesToDelete = [NSMutableArray array];
for (TPPointData * pointData in points.selectedObjects) {
NSLog(@"PointData %@", pointData);
NSLog(@"PointData.node = %@", pointData.node);
TPNode * node = pointData.node;
if (pointData == pointData.node.originData) {
//delete everything
[nodesToDelete addObject:pointData.node];
if (pointData.node.bcpInData!=nil) {
NSLog(@"deleting bcpInData: %@", pointData.node.bcpInData);
[moc deleteObject:pointData.node.bcpInData];
pointData.node = nil;
}
if (pointData.node.bcpOutData!=nil) {
NSLog(@"deleting bcpOutData: %@", pointData.node.bcpOutData);
[moc deleteObject:pointData.node.bcpOutData];
pointData.node = nil;
}
NSLog(@"deleting originData: %@", pointData.node.bcpOutData);
[moc deleteObject:pointData];
pointData.node = nil;
} else { //delete just object
[moc deleteObject:pointData];
pointData.node = nil;
}
NSLog(@"node: %@", node);
}
NSMutableArray * contoursToDelete = [NSMutableArray array];
for (TPNode * node in nodesToDelete) {
if (node.contour.nodes.count == 1) {
[contoursToDelete addObject:node.contour];
}
[moc deleteObject:node];
}
for (TPContour * contour in contoursToDelete) {
[moc deleteObject:contour];
}
[points didChangeValueForKey:@"arrangedObjects"];
[undoManager endUndoGrouping];
}

bcpOutDataを削除しようとさえしないのはなぜですか? 削除前の originDataは null です。削除後もbcpInDataとbcpOutDataはノード オブジェクトに存在します。元に戻すことは引き続き可能です。
bcpInDataまたはbcpOutDataコードのみを削除しようとすると、originDataのみが再度削除されます。

何か助けはありますか？
