ios - Converting HTML text into plain text using Objective-C -


i have huge nsstring html text inside. length of string more 3.500.000 characters. how can convert html text nsstring plain text inside. using scanner , works slowly. idea ?

it depends ios version targeting. since ios7 there built-in method not strip html tags, put formatting string:

objective-c

[[nsattributedstring alloc] initwithdata:[htmlstring datausingencoding:nsutf8stringencoding] options:@{nsdocumenttypedocumentattribute: nshtmltextdocumenttype, nscharacterencodingdocumentattribute: [nsnumber numberwithint:nsutf8stringencoding]} documentattributes:nil error:nil];

swift

let attributedstring = try nsattributedstring(data: htmlstring.datausingencoding(nsutf8stringencoding)!,                                               options: [nsdocumenttypedocumentattribute: nshtmltextdocumenttype],                                               documentattributes: nil)

if need remove between < , > (dirty way!!!), might problematic if have these characters in string, use this:

- (nsstring *)stringbystrippinghtml {    nsrange r;    nsstring *s = [[self copy] autorelease];    while ((r = [s rangeofstring:@"<[^>]+>" options:nsregularexpressionsearch]).location != nsnotfound)      s = [s stringbyreplacingcharactersinrange:r withstring:@""];    return s; }
