Let's assume I have the string
NSString* myString = @"Hello,";
How can I remove the comma without leaving a space? I have tried:
NSString* newString = [myString stringByReplacingOccurrencesOfString:@"," withString:@""];
and
NSString* newString = [myString stringByTrimmingCharactersInSet:[NSCharacterSet punctuationCharacterSet]];
But both are leaving spaces.
NSString *newString = [myString substringToIndex:5];
That will ensure that there are only 5 characters in the string, but beware that this will also throw an exception if there are not at least 5 characters in the string to begin with. How are you handling this string? Is it being displayed to the user? Is it being written to a file? The code that you posted does not reproduce the error, so perhaps you should post the code that you are having a problem with.
