Core Plot causing crash on device but not simulator.
- by Eric
I'm using core plot to create a small plot in one of my view controllers. I have been pulling my hair out trying to track down this error. I install on the simulator and it works fine but as soon as I put it on my device I get the following error:
2010-02-04 22:15:37.394 Achieve[127:207] *** -[NSCFString drawAtPoint:withTextStyle:inContext:]: unrecognized selector sent to instance 0x108530

Here is my viewDidLoad method:

[self loadData];
self.graph = [[CPXYGraph alloc] initWithFrame: self.plotView.frame];

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];
CPXYPlotSpace *plotSpace = (CPXYPlotSpace *)graph.defaultPlotSpace;
plotSpace.xRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0)
length:CPDecimalFromFloat(maxX)];
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;
// axisSet.xAxis.majorIntervalLength = [[NSDecimalNumber decimalNumberWithString:@"0"]decimalValue];
axisSet.xAxis.minorTicksPerInterval = 0;
axisSet.xAxis.majorTickLineStyle = nil;
axisSet.xAxis.minorTickLineStyle = nil;
axisSet.xAxis.axisLineStyle = lineStyle;
axisSet.xAxis.minorTickLength = 0;
axisSet.xAxis.majorTickLength = 0;
axisSet.xAxis.labelFormatter = nil;
axisSet.xAxis.labelTextStyle = nil;
axisSet.yAxis.majorIntervalLength = [[NSDecimalNumber decimalNumberWithString:intY]decimalValue];
axisSet.yAxis.minorTicksPerInterval = 5;
axisSet.yAxis.majorTickLineStyle = lineStyle;
axisSet.yAxis.minorTickLineStyle = lineStyle;
axisSet.yAxis.axisLineStyle = lineStyle;
axisSet.yAxis.minorTickLength = 2.0f;
axisSet.yAxis.majorTickLength = 4.0f;
axisSet.yAxis.labelFormatter = percentFormatter;
axisSet.yAxis.labelTextStyle = whiteText;
CPScatterPlot *xSquaredPlot = [[[CPScatterPlot alloc]initWithFrame:graph.defaultPlotSpace.graph.bounds] autorelease];
xSquaredPlot.identifier = @"Plot";
xSquaredPlot.dataLineStyle.lineWidth = 4.0f;
xSquaredPlot.dataLineStyle.lineColor = [CPColor yellowColor];
xSquaredPlot.dataSource = self;
[graph addPlot:xSquaredPlot];
}
Any help would be appreciated!
