Я использую основной участок, чтобы создать небольшой участок в одном из моих контроллеров. Я вытаскиваю свои волосы, пытаясь отследить эту ошибку. Установить на тренажере, и он работает нормально, но как только я положил его на моем устройстве я получаю следующее сообщение об ошибке:Основной участок, вызывающий крах на устройстве, но не симулятор

Вот мой viewDidLoad метод:

hostingView.hostedLayer = graph;
graph.paddingLeft = 50;
graph.paddingTop = 10;
graph.paddingRight = 10;
graph.paddingBottom = 10;
percentFormatter = [[NSNumberFormatter alloc] init];
[percentFormatter setPercentSymbol:@"%"];
[percentFormatter setNumberStyle:NSNumberFormatterPercentStyle];
[percentFormatter setLocale: [NSLocale currentLocale]];
[percentFormatter setMultiplier:[NSNumber numberWithInt:1]];
[percentFormatter setMaximumFractionDigits:0];

plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(minY)
length:CPDecimalFromFloat(maxY-minY)];
CPLineStyle *lineStyle = [[CPLineStyle lineStyle]retain];
lineStyle.lineColor = [CPColor grayColor];
lineStyle.lineWidth = 1.0f;
CPTextStyle *whiteText = [CPTextStyle textStyle];
whiteText.color = [CPColor whiteColor];
CPXYAxisSet *axisSet = (CPXYAxisSet *)graph.axisSet;

Любая помощь будет оценена!
