遇到需要将数字转汉字的需求，如下：1转一 原值 1.59999999
typedef CF_ENUM(CFIndex, CFNumberFormatterRoundingMode) {
kCFNumberFormatterRoundCeiling = 0,//四舍五入,直接输出2
kCFNumberFormatterRoundFloor = 1,//保留小数输出1.6
kCFNumberFormatterRoundDown = 2,//加上了人民币标志,原值输出￥1.6
kCFNumberFormatterRoundUp = 3,//本身数值乘以100后用百分号表示,输出160%
kCFNumberFormatterRoundHalfEven = 4,//输出1.5999999E0
kCFNumberFormatterRoundHalfDown = 5,//原值的中文表示,输出一点五九九...
kCFNumberFormatterRoundHalfUp = 6//原值中文表示,输出第二
};
方法：
+ (NSString*)stringWithNumber:(int)number
{
NSNumberFormatter*formatter = [[NSNumberFormatteralloc]init];
formatter.numberStyle=kCFNumberFormatterRoundHalfDown;
return[formatterstringFromNumber:[NSNumbernumberWithInt:number]];
}
