Crashing app when i try to use scan

[sauryatechnologies]

i have tried several time to solve crashing issue, but not get success..
app crash in LBXScanView.m file, inside -(void) drawScanRect function on below code line at component[0]; getting null

const CGFloat *components = CGColorGetComponents(_viewStyle.notRecoginitonArea.CGColor);
CGFloat red_notRecoginitonArea = components[0]; // crash here
CGFloat green_notRecoginitonArea = components[1];
CGFloat blue_notRecoginitonArea = components[2];
CGFloat alpa_notRecoginitonArea = components[3];

all components having null value: thats why i think crashing
