遇到需要將數字轉漢字的需求，如下：1轉一 ?原值 1.59999999

typedef CF_ENUM(CFIndex, CFNumberFormatterRoundingMode) {

kCFNumberFormatterRoundCeiling = 0,//四舍五入,直接輸出2

kCFNumberFormatterRoundFloor = 1,//保留小數輸出1.6

kCFNumberFormatterRoundDown = 2,//加上了人民幣標志,原值輸出￥1.6

kCFNumberFormatterRoundUp = 3,//本身數值乘以100后用百分號表示,輸出160%

kCFNumberFormatterRoundHalfEven = 4,//輸出1.5999999E0

kCFNumberFormatterRoundHalfDown = 5,//原值的中文表示,輸出一點五九九...

kCFNumberFormatterRoundHalfUp = 6//原值中文表示,輸出第二

};

方法：

+ (NSString*)stringWithNumber:(int)number

{

NSNumberFormatter*formatter = [[NSNumberFormatteralloc]init];

formatter.numberStyle=kCFNumberFormatterRoundHalfDown;

return[formatterstringFromNumber:[NSNumbernumberWithInt:number]];

}
