设置了行间距之后，与 placeholderText 位置有偏差

[lijialiang]

大概通过如下代码设置行高以及 placeholder

_textView = [[YYTextView alloc] init];
_textView.placeholderText = @"测试的";

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineSpacing = 10;

NSDictionary *attributes = @{
                              NSFontAttributeName:[UIFont systemFontOfSize:26.0f / 2],
                              NSParagraphStyleAttributeName:paragraphStyle
                              };
_textView.attributedText = [[NSAttributedString alloc] initWithString:_textView.text attributes:attributes];

请问该如何设置行高，让 placeholderText 位置与 输入文字 位置一致？

这么写试试

_textView = [[YYTextView alloc] initWithFrame:self.view.frame];
_textView.placeholderText = @"位置有偏差";
_textView.placeholderFont = [UIFont systemFontOfSize:18];
NSMutableAttributedString *mAtt = [[NSMutableAttributedString alloc] initWithString:@""];
[mAtt addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:18] range:NSMakeRange(0, mAtt.length)];
mAtt.yy_lineSpacing = 6.0f;
mAtt.yy_kern = @(0.5);
_textView.selectedRange = NSMakeRange(mAtt.length, 0);
_textView.attributedText = mAtt;
_textView.font = [UIFont systemFontOfSize:18];
_textView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
