Remove all whitespace from NSString

@"this string contains blank spaces".

How can we convert this string into @"thisstringcontainsblankspaces".

I mean how can we trim all the blank spaces and new line charecters in a string. I have already tried NSCharecterSet by using whitespaceCharacterSet. But this only removes the spaces at the ends of the string and not in between....

Any ideas??

Answer 1

Use this code to remove the white space:

NSString *str    =  @"this string contains blank spaces";
NSString *newStr = [str stringByReplacingOccurrencesOfString:@" " withString:@""];

Answer 2

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

Answer 3

Use following code:

[YourString stringByReplacingOccurrencesOfString:@" " withString:@""];

You can pass any character or word which you want to replace at

stringByReplacingOccurrencesOfString:@" "

and replacing word/string/character:

withString:@" "

Enjoy coding.
