本文深入探讨了如何在iOS开发中使用Objective-C和Swift实现文本样式与属性的高级应用，包括添加删除线、下划线、设置字体、粗细、颜色等特性，并通过实例展示了如何在UILabel中应用这些样式。

NSMutableParagraphStyle *ps = [[NSMutableParagraphStyle alloc] init];
[ps setAlignment:NSTextAlignmentCenter];
NSDictionary *attribs = @{NSFontAttributeName: [UIFont fontWithName:@"Microsoft Yahei" size:45],NSParagraphStyleAttributeName:ps};
NSMutableAttributedString *attributedText =[[NSMutableAttributedString alloc] initWithString:super.text
attributes:attribs];
super.attributedText = attributedText;

NSString *testString = @"NSMutableAttributed---0";
  UILabel *testLabel = [[UILabel alloc] initWithFrame:CGRectMake(60, 100, 200, 40)];
  NSMutableAttributedString * testAttriString = [[NSMutableAttributedString alloc] initWithString:testString];
  // 添加删除线
  [testAttriString addAttribute:NSStrikethroughStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:NSMakeRange(0, testAttriString.length)];
  // 添加下划线
  [testAttriString addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:NSMakeRange(0, testAttriString.length)];
  // 设置文本的字体以及大小
  [testAttriString addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Helvetica-Bold" size:15] range:NSMakeRange(0, testAttriString.length)];
  // 设置笔画的粗细
  [testAttriString addAttribute:NSStrokeWidthAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleDouble] range:NSMakeRange(0, testAttriString.length)];
  // label的背景颜色
  [testAttriString addAttribute:NSBackgroundColorAttributeName value:[UIColor yellowColor] range:NSMakeRange(0, testAttriString.length)];
  // 目前没测出什么效果.....
  [testAttriString addAttribute:NSVerticalGlyphFormAttributeName value:[NSNumber numberWithInt:1] range:NSMakeRange(0, testAttriString.length)];
  // label上文本颜色(也会影响删除线和下划线的颜色)
  [testAttriString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, testAttriString.length)];
  testLabel.attributedText = testAttriString;
