NSDecimalNumber はより少ない数のゼロで保存されます。たとえば、テキストフィールドに $6000,00 と入力しますが、テーブルビューには $6,00 が表示されます

この問題の解決を手伝ってください

以下は私のコードです：

@property (strong, nonatomic) NSNumberFormatter *currencyFormatter;
@synthesize currencyFormatter;


- (void)viewDidLoad
{
    [super viewDidLoad];

    nameTextField.text = editGift.nameOfGift;

    currencyFormatter = [[NSNumberFormatter alloc]init];
    [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
    priceTextField.text = [currencyFormatter stringFromNumber:[editGift priceOfGift]];

}

- (IBAction)saveChanges:(id)sender {
    editGift.nameOfGift = nameTextField.text;

    [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
    NSDecimalNumber *priceAmount = [NSDecimalNumber decimalNumberWithString:priceTextField.text];
    editGift.priceOfGift = priceAmount;

    AppDelegate *myApp = (AppDelegate *) [[UIApplication sharedApplication]delegate];
    [myApp saveContext];
    [self.delegate editGiftViewControllerDidSave:self];
}

tableView で表示:

NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc]init]; 
[currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; 
cell.giftCostLabel.text = [currencyFormatter stringFromNumber:[gift priceOfGift]];

このコードを試してみてください。

 - (IBAction)saveChanges:(id)sender {
        editGift.nameOfGift = nameTextField.text;


    NSDecimalNumber *priceAmount = [NSDecimalNumber decimalNumberWithString:priceTextField.text];

     editGift.priceOfGift =priceAmount;



        AppDelegate *myApp = (AppDelegate *) [[UIApplication sharedApplication]delegate];
        [myApp saveContext];
        [self.delegate editGiftViewControllerDidSave:self];
    }

テーブルビューでこれを試してください

 NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc] init];
    [currencyFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];


cell.giftCostLabel.text = [currencyFormatter stringFromNumber:editGift.priceOfGift];
