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）;

試試這個代碼，但它會暗戀：

float myfloat = [s.stockPrice floatValue]; 

沒有錯誤。

有人能幫助我嗎？

Answer 1

不應該是[stockObject.stockPric floatValue]？
