NSAttributedString с прикрепленным изображением и NSTextTab, текст не выровнен

Проблема связана с параметром location в NSTextTab

• Согласно описанию, параметр location помогает позиционировать текст от левого поля. Итак, это то, что нам нужно, просто замените строки ниже

  pStyle.tabStops =  @[ [[NSTextTab alloc] initWithTextAlignment:NSTextAlignmentLeft location:tabLocation options:[NSDictionary dictionary]] ];
  

  с

  pStyle.tabStops = @[[[NSTextTab alloc] initWithTextAlignment:NSTextAlignmentLeft location:[self getTextLocationFor:@"test"]  options:[NSDictionary dictionary]] ];
  

• Добавьте метод getTextLocationFor: для расчета местоположения следующим образом.

  -(CGFloat)getTextLocationFor:(NSString *)inputStr{
       CGSize maximuminputStringWidth = CGSizeMake(FLT_MAX, 30);
       CGRect textRect = [inputStr boundingRectWithSize:maximuminputStringWidth
                                          options:NSStringDrawingUsesLineFragmentOrigin
                                       attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:15]}
                                          context:nil];
       UIImageView * testImage = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"close_red"]];//Change image name with yours
  
       return textRect.size.width + testImage.frame.size.width +2;
  }
  

• Вот и все, мы готовы запустить ваш проект, теперь все будет хорошо.

РЕЗУЛЬТАТ:

если я вас правильно понял, попробуйте этот код:

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 460, 460)];
label.numberOfLines = 0;
[self.view addSubview:label];

NSMutableParagraphStyle *pStyle = [[NSMutableParagraphStyle alloc] init];
pStyle.tabStops = @[ [[NSTextTab alloc] initWithTextAlignment:NSTextAlignmentLeft location:40 options:@{}] ];

NSTextAttachment *textAttachment = [[NSTextAttachment alloc] init];
textAttachment.image = [UIImage imageNamed:@"img"];
textAttachment.bounds = CGRectMake(0, -3, 30, 30);


NSString *string = [NSString stringWithFormat:@"title\n\r\u2022 %@", [@[ @"description1", @"description2" ] componentsJoinedByString:@"\n\r\u2022 "]];

NSMutableAttributedString *attributedString = [[NSMutableAttributedString attributedStringWithAttachment:textAttachment] mutableCopy];
[attributedString appendAttributedString:[[NSMutableAttributedString alloc] initWithString:string attributes:@{NSParagraphStyleAttributeName : pStyle}]];

label.attributedText = attributedString;

Вот результат

ОБНОВЛЕНИЕ

Вы можете добиться этого только с помощью TextKit (NSTextLayoutManager) и указать область, которая должна использоваться для рисования текста, или использовать простое решение и подкласс из UIView.

Вот решение с видом
