I have a very simple piece of code that crashes when setting the NSDecimalNumber.
the code looks like this
NSDecimalNumber *price = nil;
NSString *variantPrice = nil;
variantPrice = fcVariantRow[@"fcVariantPrice"];
price = [NSDecimalNumber decimalNumberWithString:variantPrice];
It crashes when assigning the value to variable price with the following crash info

libc++abi.dylib: terminating with uncaught exception of type NSException
The debugs shows me that the NSString has a correct value as follows
017-12-20 15:26:11.523626+0800 NWMPos[28837:18554790] Jongel 4 = 99
99 is the value of the NSString
Why is this crashing?
fcVariantRow[@"fcVariantPrice"] returns NSNumber type.
just use
price = (NSDecimalNumber*) fcVariantRow[@"fcVariantPrice"];
