-(IBAction)buttonPressed1:(id)sender
{
double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue];
SumCurrency.text = [NSString stringWithFormat:@"%0.0f",currency];
}
如何将SumCurrency.text格式化为1,999而不是1999
请帮助..我是Objective-C的新手,但我的项目几乎是95％的界面构建器.
我只需要帮助上面的代码来实现..请我为此苦苦挣扎.
问候,
新手.
解决方法
我得到了答案..但是对于任何人未来的推荐
-(IBAction)buttonPressed1:(id)sender
{
double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue];
NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithInt:currency]];
SumCurrency.text = [NSString stringWithFormat:@"Converted:%@",numberAsString];
}
