Remove double quotes from NSString

Question

How to remove double quotes from NSString. Example:

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

It doesn't seem to have worked, maybe since I had to hide "in replaceOccurrencesOfString?"

Answer 1

Use the NSMakeRange function instead of your translation. This will work:

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

Answer 2

How about this?

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

Answer 3

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]; 

Exit

 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 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, this will be a problem.

Answer 4

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

Answer 5

I am working fine on my end (I copied your replacement string), both with NSMakeRange and with inline structure. Are you sure the quotes in your NSString are really ASCII 0x22 characters?

Answer 6

you can use

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