ParagraphStyle相关属性的配置可能影响全局(ParagraphStyleSet的Bug)

[Archerlly]

单独设置attributedText, 由于attributedText.yy_lineSpacing与atr1.yy_lineSpacing的值一样, 导致lab1的富文本配置都变成了attributedText的配置, 而lab2没受影响.

YYLabel *lab1 = [YYLabel new];
YYLabel *lab2 = [YYLabel new];
NSMutableAttributedString *atr1 = [[NSMutableAttributedString alloc] initWithString:@"精神科拉附近的开始垃圾\n来的看撒娇范德萨"];
NSMutableAttributedString *atr2 = [[NSMutableAttributedString alloc] initWithString:@"精神科拉附近的开始垃圾\n来的看撒娇范德萨"];

atr1.yy_lineSpacing = 3;
atr2.yy_lineSpacing = 4;

lab1.numberOfLines = 0;
lab2.numberOfLines = 0;
lab1.attributedText = atr1;
lab2.attributedText = atr2;
lab1.frame = CGRectMake(50, 50, 100, 200);
lab2.frame = CGRectMake(160,50, 100, 200);
[self.view addSubview:lab1];
[self.view addSubview:lab2];

NSMutableAttributedString *attributedText = [NSMutableAttributedString new];
[attributedText yy_appendString:@" "];

attributedText.yy_lineSpacing = 3;
attributedText.yy_headIndent = 2;
attributedText.yy_paragraphSpacing = 20;
attributedText.yy_firstLineHeadIndent = 30;

review代码发现 enumerateAttribute: inRange: options: usingBlock: 这个API遍历的时候拿错了, 期待你的修复, 谢谢!
