how to compare a string from url to NSutf8stringencoding return 1 or 0 with normal string @“1”

Question

I need to compare a string from an url using NSutf8stringencoding in order to return 1 or 0, but it always returns 0 even if the string has value 1.

Answer 1

Try the following - there could be additional whitespace characters in the strResult (like carriage returns):

if ([strResult rangeOfString:@"1"].length > 0) {
    // Do something...
}

Answer 2

There are probably other characters in the string.

Use

[strResult stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
