Html 字符串从服务器获取我尝试转换为属性字符串。使用

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

具有\U00002028\n 的属性字符串会导致显示字符串在文本中出现间距和换行。如何才能删除这样的东西。

从 NSMutableAttributedString 中修剪前导和尾随空格

NSString * _strAchievementMsg= @" Hi Test the White space "; NSString * htmlString = [NSString stringWithFormat"<html><div>%@</div></html>",_strAchievementMsg]; NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithData: [htmlString dataUsingEncoding:NSUnicodeStringEncoding] options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: [NSNumber numberWithInt:NSUTF8StringEncoding] } documentAttributes: nil error: nil ]; NSCharacterSet *charSet = [NSCharacterSet whitespaceAndNewlineCharacterSet]; NSRange range = [attString.string rangeOfCharacterFromSet:charSet]; while (range.length != 0 && range.location == 0) { [attString replaceCharactersInRange:range withString""]; range = [attString.string rangeOfCharacterFromSet:charSet]; } // Trim trailing whitespace and newlines. range = [attString.string rangeOfCharacterFromSet:charSet options:NSBackwardsSearch]; while (range.length != 0 && NSMaxRange(range) == attString.length) { [attString replaceCharactersInRange:range withString""]; range = [attString.string rangeOfCharacterFromSet:charSet options:NSBackwardsSearch]; }
