lctext's Issues
当富文本设置某部分文字字号时 点击范围失效
NSMutableAttributedString * attributedText = [[NSMutableAttributedString alloc] initWithString:@"使用约束布局titleLabel！欢迎使用LCText!"];
[attributedText addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:13] range:NSMakeRange(0, 1)];
一些疑惑
你好
在LCTextSelectedHelper.m中
NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithAttributedString:label.attributedText];
NSRange textRange = NSMakeRange(0, attributedText.length);
[attributedText addAttribute:NSFontAttributeName value:label.font range:textRange];
NSMutableParagraphStyle *paragraphStyle = [NSMutableParagraphStyle new];
paragraphStyle.alignment = label.textAlignment;
[attributedText addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:textRange];
[self.textStorage setAttributedString:attributedText];
这些代码
在 NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithAttributedString:label.attributedText];之后，为什么要再增加font和paragraphStyle的富文本样式呢？这些样式在label.attributedText已经包含了，不太明白这里为什么要再写一次，望回复
