Remove double quotes from NSString

How do I remove double quotes from an NSString. Example:

//theMutableString: "Hello World"

[theMutableString replaceOccurrencesOfString:@"\"" withString:@"" options:NSCaseInsensitiveSearch range:(NSRange){0,[theMutableString length]}]

It doesn't seem to work, maybe since I had to escape the " in the replaceOccurrencesOfString?

How about this ?

NSCharacterSet *quoteCharset = [NSCharacterSet characterSetWithCharactersInString:@"\""];
NSString *trimmedString = [toBeTrimmedString stringByTrimmingCharactersInSet:quoteCharset];

You can use

string = [string stringByReplacingOccurrencesOfString:@"\"" withString:@"" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [string length])];

I works perfectly on my end (I copy-pasted your replace line), with both NSMakeRange and the inline struct cast. Are you sure the quotes in your NSString are really the ASCII character 0x22?

Assuming the mString bit is a typo. I ran this code and the answer was as expected

NSMutableString * theMutableString = [[NSMutableString alloc] initWithString:@"\"Hello World!\""];
NSLog(@"%@",theMutableString);

[theMutableString replaceOccurrencesOfString:@"\"" withString:@"" options:NSCaseInsensitiveSearch range:(NSRange){0,[theMutableString length]}];

NSLog(@"%@",theMutableString);

[theMutableString release];

Output

2010-01-23 15:49:42.880 Stringtest[2039:a0f] "Hello World!"
2010-01-23 15:49:42.883 Stringtest[2039:a0f] Hello World!

So it mString was a typo in your question, then your code is correct and the problem is elsewhere. If mString is a typo in your code than that would be the issue.

Use the NSMakeRange function instead of your cast. This'll work:

[mString replaceOccurrencesOfString:@"\"" withString:@"" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [mString length])];

What happens if you use NSMakeRange(0, [theMutableString length]) instead of trying to cast an inline struct?
