how to remove quote and slash from string in iphone

Hi friends... I am using regular expression so I get string but with double quote and slash but I dont want that. I want string value without slash and double quotes. I try this I'm but not getting proper answer.

I get error after running application [/Users/pradeepyadav/Desktop/RegexKitLiteDemo/Classes/RegexKitLiteDemoAppDelegate.m:108:0 /Users/pradeepyadav/Desktop/RegexKitLiteDemo/Classes/RegexKitLiteDemoAppDelegate.m:108: error: incompatible block pointer types initializing 'void (^)(struct NSString *, NSUInteger, BOOL *)', expected 'void (^)(struct objc_object *, NSUInteger, BOOL *) I get this error line

Second one is this : [/Users/pradeepyadav/Desktop/RegexKitLiteDemo/Classes/RegexKitLiteDemoApp开发者_Python百科Delegate.m:105:0 /Users/pradeepyadav/Desktop/RegexKitLiteDemo/Classes/RegexKitLiteDemoAppDelegate.m:105: warning: 'NSString' may not respond to '+stringByTrimmingCharactersInSet:

I get this error line [webData length] encoding:NSUTF8StringEncoding];

    matchArray = [loginStatus arrayOfCaptureComponentsMatchedByRegex:regexString];
    NSMutableArray *newArray = [[NSMutableArray alloc] initWithCapacity:[matchArray count]];

    }];//******************


    //NSLog(@"matchArray: %@", matchArray);


    lstAirports = [[NSMutableArray alloc] initWithCapacity:[matchArray count]];

    for (int i = 0; i < [matchArray count]; i++) {
        airport *air=[[airport alloc]init];

        //code
        air.Code = [[matchArray objectAtIndex: i] objectAtIndex: 1];
        NSLog(@"air.Code: %@\n",air.Code);
        //name
        NSString *temp=[[matchArray objectAtIndex: i] objectAtIndex: 2];
        NSArray *arrParts=[temp componentsSeparatedByString:@""","];
        //air.Name=arrParts[2];
        air.Name=[arrParts objectAtIndex:2];
        NSLog(@"air.Name: %@\n",air.Name);
        //destination airports
        temp=[[matchArray objectAtIndex: i] objectAtIndex: 3];
        arrParts=[temp componentsSeparatedByString:@","];
        air.DestinationAirports =arrParts;
        NSLog(@"air.DestinationAirports: %@\n",air.DestinationAirports);
        [lstAirports addObject: air];
        NSLog(@"lstAirports: %@\n",lstAirports);
    }

    //[webData release]; 
} 

please some help me fast it's vital for me

You don't need RegExp to remove occurrences of string in NSString.

See the example below, i hop it will help you:

NSString *str = @"fdf\"fdsfdsf\"fsdfsf/fsdfsdfsf\\fsdfsdf\\fsdffsd//fsdfsf\"fsdf/\\\"";
str = [str stringByReplacingOccurrencesOfString:@"\"" withString:@""];
str = [str stringByReplacingOccurrencesOfString:@"\\" withString:@""];
str = [str stringByReplacingOccurrencesOfString:@"/" withString:@""];
NSLog(@"%@", str);

Check for the usage of

stringByReplacingOccurrencesOfString:withString:

in

You can replace them with "" characters.
