iphone - 如何在以千为单位的 UILabel 值中添加逗号

Question

我有 UILabel 我在其中显示浮点值我希望如果值以千为单位如 $1000.00 那么标签应该显示 $1,000.00

使用以下方式我的代码显示

$1000.00

        labelOne.text=[NSString stringWithFormat:@"$ %.2f",f_Cost_of_Vacination_NV];

Answer 1

您需要使用NSNumberFormatter

NSString *formatted = [NSNumberFormatter localizedStringFromNumber:@(f_Cost_of_Vacination_NV) numberStyle:NSNumberFormatterCurrencyStyle];
NSLog(@"%@", formatted); // will log it as 1,000.00

Answer 2

您需要使用数字样式 Currency.this 可能会解决您的问题，使用 NSNumberFormatter... 并使用此行设置货币样式

NSNumberFormatterCurrencyStyle.

看到这个

NSNumber *number=[[NSNumber alloc]initWithInt:1000];


    NSString *No = [NSNumberFormatter localizedStringFromNumber:number numberStyle:NSNumberFormatterCurrencyStyle];
    NSLog(@"%@", No);

    UILabel * text=[NSString stringWithFormat:@"%@",No];

    NSLog(@"%@",text);

Answer 3

你可以这样做：

double currency=1000;
    NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init] ;
    [numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
    NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithInt:currency]];
    NSLog(@" print Converted:%@",numberAsString]);

快乐编码！

Answer 4

试试这个

    float value = 200000;
    NSNumberFormatter * formatter = [NSNumberFormatter new];
    [formatter setNumberStyle:NSNumberFormatterDecimalStyle];
    [formatter setMaximumFractionDigits:2]; // Set this if you need 2 digits
    NSString * newString =  [formatter stringFromNumber:[NSNumber numberWithFloat:value]];

 labelOne.text=[NSString stringWithFormat:@"$ %@",newString];
