Remove HTML Tags from an NSString on the iPhone
Solution 1:
A quick and "dirty" (removes everything between < and >) solution, works with iOS >= 3.2:
-(NSString *) stringByStrippingHTML {
NSRange r;
NSString *s = [[self copy] autorelease];
while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
s = [s stringByReplacingCharactersInRange:r withString:@""];
return s;
}
I have this declared as a category os NSString.
Solution 2:
This NSString category uses the NSXMLParser to accurately remove any HTML tags from an NSString. This is a single .m and .h file that can be included into your project easily.

You then strip html by doing the following:
Import the header:
#import "NSString_stripHtml.h"
And then call stripHtml:
NSString* mystring = @"<b>Hello</b> World!!";
NSString* stripped = [mystring stripHtml];
// stripped will be = Hello World!!
This also works with malformed HTML that technically isn't XML.
Solution 3:
UITextView *textview= [[UITextView alloc]initWithFrame:CGRectMake(10, 130, 250, 170)];
NSString *str = @"This is <font color='red'>simple</font>";
[textview setValue:str forKey:@"contentToHTMLString"];
textview.textAlignment = NSTextAlignmentLeft;
textview.editable = NO;
textview.font = [UIFont fontWithName:@"vardana" size:20.0];
[UIView addSubview:textview];
work fine for me
Solution 4:
You can use like below
-(void)myMethod
{
NSString* htmlStr = @"<some>html</string>";
NSString* strWithoutFormatting = [self stringByStrippingHTML:htmlStr];
}
-(NSString *)stringByStrippingHTML:(NSString*)str
{
NSRange r;
while ((r = [str rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
{
str = [str stringByReplacingCharactersInRange:r withString:@""];
}
return str;
}
Solution 5:
use this
NSString *myregex = @"<[^>]*>"; //regex to remove any html tag
NSString *htmlString = @"<html>bla bla</html>";
NSString *stringWithoutHTML = [hstmString stringByReplacingOccurrencesOfRegex:myregex withString:@""];
