问题描述
我有一个浮点数,我想显示一个小数位。例如。 104.8135674 ...以英语显示为104.8。通常我会使用:
myString = [NSString stringWithFormat:@%。1f,myFloat];
但是,我想本地化该号码,所以我试过:
myString = [NSString localizedStringWithFormat:@%。1f,myFloat];
这样可以分配正确的十进制符号/ p>
英语:104.8
德语:104,8
但是,对于不使用(0123456789)的语言,使用正确的小数符号,但是例如
巴林 - 阿拉伯语:104,8(应使用不同的符号表示数字)
所以我试过:
myString = [NSNumberFormatter localizedStringFromNumber:[NSNumber numberWithFloat:myFloat] numberStyle:kCFNumberFormatterDecimalStyle];
但是我似乎不能指定小数位数。它给出例如。
英语:104.813
NSNumberFormatter -setMaximumFractionDigits:
用于这个目的,你可以重用相当不错的格式化程序:
NSNumberFormatter * formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:kCFNumberFormatterDecimalStyle];
[formatter setMaximumFractionDigits:1];
[formatter setLocale:[NSLocale currentLocale]];
NSString * myString = [formatter stringFromNumber:[NSNumber numberWithFloat:123.456]];
I have a float that I'd like to display to one decimal place. E.g. 104.8135674... to be displayed as 104.8 in English. Usually I'd use:
myString = [NSString stringWithFormat:@"%.1f",myFloat];
However, I'd like to localize the number, so I tried:
myString = [NSString localizedStringWithFormat:@"%.1f",myFloat];
This works to assign the correct decimal symbol (e.g.
English: 104.8
German: 104,8
However, for languages that use don't use arabic numerals (0123456789), the correct decimal symbol is used, but the numbers are still in arabic numerals. e.g.
Bahrain-Arabic: 104,8 (it should use different symbols for the numbers)
So I tried:
myString = [NSNumberFormatter localizedStringFromNumber:[NSNumber numberWithFloat:myFloat] numberStyle:kCFNumberFormatterDecimalStyle];
But with that I can't seem to specify the number of decimal places. It gives e.g.
English: 104.813
NSNumberFormatter -setMaximumFractionDigits:
is used for that purpose and you can reuse the formatter which is quite good:
NSNumberFormatter * formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:kCFNumberFormatterDecimalStyle];
[formatter setMaximumFractionDigits:1];
[formatter setLocale:[NSLocale currentLocale]];
NSString * myString = [formatter stringFromNumber:[NSNumber numberWithFloat:123.456]];
