推荐答案

考虑字符串.

    NSString *str = @"$2,000.00";

创建数字格式器.

    NSNumberFormatter *nf = [[NSNumberFormatter alloc] init];

重要的事情" .

The "important thing".

    [nf setNumberStyle:NSNumberFormatterCurrencyStyle];

这就是您想要的".

"Here is what you want".

    NSNumber *number = [nf numberFromString:str];
    float f = [number floatValue];

当然，请释放数字格式化程序.

And of course, release the number formatter.

    [nf release];
