Ios 如何将货币字符串转换为数字

我有以下字符串：

R$1.234.567,89

我需要它看起来像：1.234.567.89

我该怎么做

这就是我所尝试的：

NSString* cleanedString = [myString stringByReplacingOccurrencesOfString:@"." withString:@""];
cleanedString = [[cleanedString stringByReplacingOccurrencesOfString:@"," withString:@"."]
                                     stringByTrimmingCharactersInSet: [NSCharacterSet symbolCharacterSet]];

---

这是可行的，但我认为一定有更好的办法。建议？

如果只想从字符串中删除前两个字符，可以这样做

NSString *cleanedString = [myString substringFromIndex:2];

---

如果您的数字始终在$之后，但前面有更多字符，则可以将其设置为：

NSString* test = @"R$1.234.567,89";
NSString* test2 = @"TESTERR$1.234.567,89";
NSString* test3 = @"HEllo123344R$1.234.567,89";


NSLog(@"%@",[self makeCleanedText:test]);
NSLog(@"%@",[self makeCleanedText:test2]);
NSLog(@"%@",[self makeCleanedText:test3]);

方法是：

- (NSString*) makeCleanedText:(NSString*) text{

    int indexFrom = 0;

    for (NSInteger charIdx=0; charIdx<[text length]; charIdx++)
        if ( '$' == [text characterAtIndex:charIdx])
            indexFrom = charIdx + 1;

    text = [text stringByReplacingOccurrencesOfString:@"," withString:@"."];
    return [text substringFromIndex:indexFrom];
}
