我有一个带有多个段落的属性字符串。
我给了FirstLineHeadIndent = 2.12.
现在我想将FirstLineHeadIndent=0
提供给第1段
和FirstLineHeadIndent=2
到属性字符串中的第2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,
};
它将为paragaraph提供头部空间。 请帮我。 我正在上传图片以获取更多帮助: -

所以,解决方案是使用2段款式
您的NSString
以\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
