iphone-字符串中替换/”

我的字符串如下：

"phone" : "555-522-8243",
"name" : "Anna Haro"

我想把"全都换成/"，怎么样实现呢？

NSString* yourNewString=  [yourOldaString stringByReplacingOccurrencesOfString:@"\"" withString:@"/\""];
NSLog(@"\n New String %@",yourNewString);

试试看，我没具体调试。
其他办法暂时没想出来

NSString *sourceString = nil;
    NSMutableString *resultString = nil;
    int length = [sourceString length];
    for (int i = 0;i<length;i++) {
        NSRange range ;
        range.location =i;
        range.length =1;
        if ([[sourceString substringWithRange:range] isEqualToString:@"\""]) {
            [resultString appendFormat:@"\\\""];
        }else{
            [resultString appendString:[sourceString substringWithRange:range]];
        }
    }

    //method 2
    NSArray *subStrings = [sourceString componentsSeparatedByString:@"\""];
    NSString *new = [subStrings componentsJoinedByString:@"\\\""];

//method3
    NSString *str = nil;
    [str stringByReplacingOccurrencesOfString:<#(NSString *)#> withString:<#(NSString *)#>]
