NSnumber到NSstring

Question

Stock *stockObject;

stockObject = [[Stock alloc]initWithIssuingCompany:addCompany stockName:@"one" stockPrice:[NSNumber numberWithFloat:150.3]];       

[availableStocks addObject:stockObject];


float myfloat = [s.stockPrice floatValue];

NSLog（@＆＃34; singleton @％f＆＃34;，myfloat）;

试试这段代码，但它会粉碎：

float myfloat = [s.stockPrice floatValue];

没有错误。

有人可以帮助我吗？

Answer 1

不应该是[stockObject.stockPric floatValue]？
