how to remove HTML Tags from NSString in iphone?

A simple solution with iOS 7:

NSString *html = @"S.Panchami 01.38<br>Arudra 02.01<br>V.08.54-10.39<br>D.05.02-06.52<br> <font color=red><u>Festival</u></font><br><font color=blue>Shankara Jayanthi<br></font>";
NSAttributedString *attr = [[NSAttributedString alloc] initWithData:[html dataUsingEncoding:NSUTF8StringEncoding]
                                                            options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
                                                                      NSCharacterEncodingDocumentAttribute:@(NSUTF8StringEncoding)}
                                                 documentAttributes:nil
                                                              error:nil];
NSLog(@"html: %@", html);
NSLog(@"attr: %@", attr);
NSLog(@"string: %@", [attr string]);
NSString *finalString = [attr string];

If your working with ios 7 then you can apply this code

[[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: [NSNumber numberWithInt:NSUTF8StringEncoding]} documentAttributes:nil error:nil];

for ios lower than ios 7 use this code,

(NSString *) stringByStrippingHTML {
  NSRange r;
  NSString *s = [[self copy] autorelease];
  while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
    s = [s stringByReplacingCharactersInRange:r withString:@""];
  return s;
}

This should remove all content between < >

NSString * yourString = @"<br>Arudra 02.01<br>V.08.54-10.39<br>D.05.02-06.52<br> <font color=red><u>Festival</u></font><br><font color=blue>Shankara Jayanthi<br></font>";

NSRange r;
NSMutableString * cleanString = [NSMutableString stringWithString:yourString];
while ((r = [cleanString rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
    cleanString = [cleanString stringByReplacingCharactersInRange:r withString:@""];
