Custom Position (Objective C)

Customize the number and positions of pieces and boom-buttons.

Swift | Objective-C

Custom Position

Sometimes we may want 12 boom-buttons or more, and perhaps we need to put the 12 pieces and boom-buttons to the positions that are not supported in BMB. Then you can customize number and positions of pieces and boom-buttons.

bmb.buttonEnum = VHButtonTextInsideCircle;
bmb.piecePlaceEnum = VHPiecePlaceCustom;
bmb.buttonPlaceEnum = VHButtonPlaceCustom;

for (int i = 0; i < 3; i++)
{
    [bmb addBuilder:[BuilderManager textInsideCircleButtonBuilder]];
}

Then you need to tell BMB the positions of pieces:

[bmb.customPiecePositions addObject:[NSValue valueWithCGPoint:CGPointMake(+6, -6)]];
[bmb.customPiecePositions addObject:[NSValue valueWithCGPoint:CGPointMake(0, 0)]];
[bmb.customPiecePositions addObject:[NSValue valueWithCGPoint:CGPointMake(-6, +6)]];

And the positions of boom-buttons:

[bmb.customButtonPositions addObject:[NSValue valueWithCGPoint:CGPointMake(-60, -60)]];
[bmb.customButtonPositions addObject:[NSValue valueWithCGPoint:CGPointMake(0, 0)]];
[bmb.customButtonPositions addObject:[NSValue valueWithCGPoint:CGPointMake(+60, +60)]];

Notice that the coordinate system is the same as iPhone but the center position is (0, 0). And you don't need to customize both pieces and boom-buttons, check demo for more details.
