iOS数字字符串转大写金额字符串（OC）

最近项目中需要前端对金额字符串进行处理，百度了未找到OC版本的。所以自己写了一个小算法，经过测试没出现啥问题。直接上代码。

复制代码-(NSString *)toCapitalLetters:(NSString *)money { //首先转化成标准格式 “200.23” NSMutableString *tempStr=[[NSMutableString alloc] initWithString:[NSString stringWithFormat:@"%.2f",[money doubleValue]]]; //位 NSArray *carryArr1=@[@"元", @"拾", @"佰", @"仟", @"万", @"拾", @"佰", @"仟", @"亿", @"拾", @"佰", @"仟", @"兆", @"拾", @"佰", @"仟" ]; NSArray *carryArr2=@[@"分",@"角"]; //数字 NSArray *numArr=@[@"零", @"壹", @"贰", @"叁", @"肆", @"伍", @"陆", @"柒", @"捌", @"玖"]; NSArray *temarr = [tempStr componentsSeparatedByString:@"."]; //小数点前的数值字符串 NSString *firstStr=[NSString stringWithFormat:@"%@",temarr[0]]; //小数点后的数值字符串 NSString *secondStr=[NSString stringWithFormat:@"%@",temarr[1]]; //是否拼接了“零”，做标记 bool zero=NO; //拼接数据的可变字符串 NSMutableString *endStr=[[NSMutableString alloc] init]; /** * 首先遍历firstStr，从最高位往个位遍历 高位----->个位 */ for(int i=(int)firstStr.length;i>0;i--) { //取最高位数 NSInteger MyData=[[firstStr substringWithRange:NSMakeRange(firstStr.length-i, 1)] integerValue]; if ([numArr[MyData] isEqualToString:@"零"]) { if ([carryArr1[i-1] isEqualToString:@"万"]||[carryArr1[i-1] isEqualToString:@"亿"]||[carryArr1[i-1] isEqualToString:@"元"]||[carryArr1[i-1] isEqualToString:@"兆"]) { //去除有“零万” if (zero) { endStr =[NSMutableString stringWithFormat:@"%@",[endStr substringToIndex:(endStr.length-1)]]; [endStr appendString:carryArr1[i-1]]; zero=NO; }else{ [endStr appendString:carryArr1[i-1]]; zero=NO; } //去除有“亿万”、"兆万"的情况 if ([carryArr1[i-1] isEqualToString:@"万"]) { if ([[endStr substringWithRange:NSMakeRange(endStr.length-2, 1)] isEqualToString:@"亿"]) { endStr =[NSMutableString stringWithFormat:@"%@",[endStr substringToIndex:endStr.length-1]]; } if ([[endStr substringWithRange:NSMakeRange(endStr.length-2, 1)] isEqualToString:@"兆"]) { endStr =[NSMutableString stringWithFormat:@"%@",[endStr substringToIndex:endStr.length-1]]; } } //去除“兆亿” if ([carryArr1[i-1] isEqualToString:@"亿"]) { if ([[endStr substringWithRange:NSMakeRange(endStr.length-2, 1)] isEqualToString:@"兆"]) { endStr =[NSMutableString stringWithFormat:@"%@",[endStr substringToIndex:endStr.length-1]]; } } }else{ if (!zero) { [endStr appendString:numArr[MyData]]; zero=YES; } } }else{ //拼接数字 [endStr appendString:numArr[MyData]]; //拼接位 [endStr appendString:carryArr1[i-1]]; //不为“零” zero=NO; } } /** * 再遍历secondStr 角位----->分位 */ if ([secondStr isEqualToString:@"00"]) { [endStr appendString:@"整"]; }else{ for(int i=(int)secondStr.length;i>0;i--) { //取最高位数 NSInteger MyData=[[secondStr substringWithRange:NSMakeRange(secondStr.length-i, 1)] integerValue]; [endStr appendString:numArr[MyData]]; [endStr appendString:carryArr2[i-1]]; } } return endStr; }
