A:
NSString *newString = [(NSString *)yourOldString stringByReplacingOccurrencesOfString:@"anystring" withString:@""];
otherwise you're going to have to get a copy of REGEXKitLite and use a regex function like:
NSString *newString = [(NSString *)yourOldString stringByReplacingOccurrencesOfRegex:@"ab\\b.\\byz" withString:@"ab yz"];

afaik a fullstop `.` in regex means "any amount of characters". You need to download regexKitLite and include it in your project.

Hi Thomas Thanks again. I tried it.No compilation error but might be some logic error.I put the code.Tell me if u have any suggestion for it. NSString *str = [[NSString alloc] init];str = @"ab This is demo yz";NSString *newstr = [[NSString alloc] init];newstr = [str stringByReplacingOccurrencesOfRegex:@"ab\\b.\\byz" withString:@"good"];

I got the answer. NSString *str = [[NSString alloc] init];str = @"ab this is demo yz";NSString *newstr = [[NSString alloc] init];newstr = [str stringByReplacingOccurrencesOfRegex:@" (.*) " withString:@"good"];

May I suggest that instead of doing `NSString *str = [[NSString alloc] init]; str= @"Hello";` You can just do: `NSString *str = [NSString stringWithFormat:@"Hello"];` then you don't have to worry about memory management or anything. :) and its just a little nicer to code and read. :)
