Question

我有以下法典:

(...)
numberStyle = [NSDecimalNumberHandler decimalNumberHandlerWithRoundingMode:NSRoundPlain
                                                                     scale:2
                                                          raiseOnExactness:NO
                                                           raiseOnOverflow:NO
                                                          raiseOnUnderflow:NO
                                                       raiseOnDivideByZero:NO];

strThree = textFieldThree.text;
strThree = [strThree stringByReplacingOccurrencesOfString:@"." withString:@""];

fieldOneDNa = (NSDecimalNumber *)[NSDecimalNumber decimalNumberWithString:strThree];
oneHundred = (NSDecimalNumber *)[NSDecimalNumber decimalNumberWithString:@"100"];
fieldOneDN = [fieldOneDNa decimalNumberByDividingBy:oneHundred
                                       withBehavior:numberStyle];

firstStepReturn = [fieldOneDN stringValue];
textFieldThree.text = firstStepReturn;
(...)

即便是零位或0位位数,我还是能够拥有位数位位位数。例如,如果将323.390条输入文本领域“案文领域3”的话,则将予以处理,并退回到文本领域,即为3233.90。目前,它显示为3233.9。

任何帮助都将受到高度赞赏。

Answer 1

缩略语


 NSDecimalNumber * dn = [NSDecimalNumber decimalNumberWithString:@"1234.5"];
 NSNumberFormatter * nf = [[NSNumberFormatter alloc] init];
 [nf setMinimumFractionDigits:2];
 [nf setMaximumFractionDigits:2];
 NSString *ns  = [nf stringFromNumber:dn];

简单

Answer 2

为什么不使用<条形码> 实地数据。

(或类似的情况――目前对《刑法》权利的怀疑度为一米)
