Question
I am looking for an objective C function (custom or built-in) that strips html tags from a string, similar to PHP's version that can be found here:
http://php.net/manual/en/function.strip-tags.php
Any help would be appreciated!
Solution
This just removes <
and >
characters and everything between them, which I suppose is sufficient:
- (NSString *) stripTags:(NSString *)str
{
NSMutableString *ms = [NSMutableString stringWithCapacity:[str length]];
NSScanner *scanner = [NSScanner scannerWithString:str];
[scanner setCharactersToBeSkipped:nil];
NSString *s = nil;
while (![scanner isAtEnd])
{
[scanner scanUpToString:@"<" intoString:&s];
if (s != nil)
[ms appendString:s];
[scanner scanUpToString:@">" intoString:NULL];
if (![scanner isAtEnd])
[scanner setScanLocation:[scanner scanLocation]+1];
s = nil;
}
return ms;
}
