NSNumber *price = [numberFormatter numberFromString:_priceTF.text]; 
NSLog([price stringValue]);

Answer 1

目前，我得到的NSNumber左右（但很奇怪）：

NSString *priceNoCurrency = [_priceTF.text stringByReplacingOccurrencesOfString:numberFormatter.currencySymbol withString:@""]; 
NSNumber *price = @(priceNoCurrency.integerValue);
