Ios 具有不同NSMutableParagraphStyle的NSAttribute字符串

我有1个带多段落的属性字符串。
我已经给出了

FirstLineHeadIndent=2.12。

现在我想给第一段加上

FirstLineHeadIndent=0

和

FirstLineHeadIndent=2

到属性字符串中的第二段

如果我将属性设置为

 NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
        paragraphStyle.lineSpacing =Line_space;
        paragraphStyle.firstLineHeadIndent =2;
        paragraphStyle.headIndent =margin_space;
        paragraphStyle.tailIndent =-margin_space;
        paragraphStyle.paragraphSpacing=paragraph_space;

        NSDictionary *ats = @{
                              NSFontAttributeName : [UIFont fontWithName:self.bookView.defaultFontFamily size:self.bookView.defaultFontSize],
                              NSParagraphStyleAttributeName : paragraphStyle,
                              };

这将给两位巴拉圭人提供头部空间。 请帮帮我。

因此，解决方案是使用两种段落样式。
您的

NSString

由一个

\n

分隔，表示两段之间的分隔

NSMutableParagraphStyle *firstParagraphStyle = [[NSMutableParagraphStyle alloc] init];
[firstParagraphStyle setFirstLineHeadIndent:0];
//Do the rest of the settings

NSMutableParagraphStyle *secondParagraphStyle = [[NSMutableParagraphStyle alloc] init];
[secondParagraphStyle setFirstLineHeadIndent:2];
//Do the rest of the settings

//You may use the same paragraphStyle, changing just the firstLineHeadIndent, and set the attributes, but for a clearer explanation, I used 2 paragraph styles
NSRange range = [[yourAttributedString string] rangeOfString:@"\n"];

[yourAttributedString addAttribute:NSParagraphStyleAttributeName value: firstParagraphStyle range:NSMakeRange(0, range.location)]; //The range is from the start to the \n

[yourAttributedString addAttribute:NSParagraphStyleAttributeName value: secondParagraphStyle range:NSMakeRange(range.location, [[yourAttributedString string] length]-range.location)]; //The range is from the start of \n to the end

你是如何将段落样式设置为你的

NSAttributedString

？@Larme我已经用NSMutableParagraphStyle设置了段落样式。但是它给了所有段落以imapact。我想将不同的样式设置为第一段和第二段。例如1）段落的行间距为2，第二段的行间距为4。你能显示所有的段落吗代码？NSMutableParagraphStyle*paragraphStyle=[[NSMutableParagraphStyle alloc]init]；paragraphStyle.firstLineHeadIndent=2；段落样式。段落间距=段落间距；NSDictionary*ats=@{NSFontAttributeName:[UIFontWithName:self.bookView.defaultFontFamily size:self.bookView.defaultFontSize]，NSParagraphStyleAttributeName:paragraphStyle，}；您需要使用两段式，范围不同。你就是这么做的吗？
