Swift 3:

let removeWhiteSpace = word.stringByRemovingWhitespaces
word = "Helloworld"

Answer 2

myStr = [myStr stringByReplacingOccurrencesOfString:@" " withString:@""];

Answer 3

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.

Answer 4

you can use remove function to remove any substring from the string

- (NSString*)remove:(NSString*)textToRemove fromString:(NSString*)input { 
    return [input stringByReplacingOccurrencesOfString:textToRemove withString:@""]; 
}

Answer 5

This will remove all space from myString.

NSString *newString = [myString stringByReplacingOccurrencesOfString:@" " withString:@""];

Answer 6

I have tried all the solutions here, none of them could remove the whitespace generated by the Chinese PinYin Input method.

After some debugging, I found this working:

NSString *newString = [myString stringByReplacingOccurrencesOfString:@"\342\200\206" withString:@""];

I have googled what the '\342\200\206' is, but failed.

Whatever, it works for me.
