objective c - iPhone - Replacing line breaks in my TextView with <br />? -

i trying convert linebreaks in uitextview <br /> tags, why next line crash? complains [nscharacterset newlinecharacterset] because when pass normal string works fine

[mymutablestring stringbyreplacingoccurrencesofstring: [nscharacterset newlinecharacterset] withstring:@"<br />"]; terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[__nscfcharacterset length]: unrecognized selector sent instance 0x7b1cc80'

a nscharacterset not nsstring.so you're passing wrong argument. if have newline "\n" characters can use:

[mymutablestring stringbyreplacingoccurrencesofstring:@"\n" withstring:@"<br />"];

if have "\r" , "\lf" can seek (untested)

nsrange range; while((range = [mymutablestring rangeofcharacterfromset: [nscharacterset newlinecharcaterset]]).location != nsnotfound) { [mymutablestring replacecharactersinrange:range withstring:@"<br />"]; }
