最後の50 行ほどNSAttributedString
しか取得できないように分割する簡単な方法はありますか?
NSMutableAttributedString *resultString = [receiveView.attributedText mutableCopy];
[resultString appendAttributedString:[ansiEscapeHelper attributedStringWithANSIEscapedString:message]];
if ([[resultString.string componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]] count]>50) {
//resultString = [resultString getLastFiftyLines];
}
