How to remove the white space in between , and pa using objective c?

Answer 1

In my case NSString was added Zero Width Space(i i used some library). so solution worked for me.

NSMutableString *newString=[[newString stringByReplacingOccurrencesOfString:@"\u200B" withString:@""] mutableCopy];

@"\u200B" is Zero width space character value.
