NSnumber in to 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（@“singleton @％f”，myfloat）;

试试这个代码，但它会暗恋：

float myfloat = [s.stockPrice floatValue]; 

没有错误。

有人能帮助我吗？

Answer 1

不应该是[stockObject.stockPric floatValue]？
