单独设置选中字体为粗体，不起作用

[200895045]

我是继承的: TYTabPagerController 1、如果默认与选中字体都设置为粗体，显示是正常的。 2、设置默认字体为正常的系统字体，选中字体为粗体，结果不起作用 self.tabBar.layout.normalTextFont = [UIFont systemFontOfSize:20]; self.tabBar.layout.selectedTextFont = [UIFont boldSystemFontOfSize:20];

我重写了下面这个方法，切换后字体可以变成粗体了，但首次启动时默认选中项的字体还是不正确

pragma mark - TYTabPagerBarDelegate

//重写Tab Cell切换方法，设置标题字体

• (void)pagerTabBar:(TYTabPagerBar )pagerTabBar transitionFromeCell:(UICollectionViewCell _Nullable)fromCell toCell:(UICollectionViewCell * _Nullable)toCell animated:(BOOL)animated {

  if (self.tabBar.layout.pagerTabBar.countOfItems == 0) { return; } void (^animateBlock)(void) = ^{ if (fromCell) { fromCell.titleLabel.font = self.tabBar.layout.normalTextFont; fromCell.titleLabel.textColor = self.tabBar.layout.normalTextColor; fromCell.transform = CGAffineTransformMakeScale(self.tabBar.layout.selectFontScale, self.tabBar.layout.selectFontScale); } if (toCell) { toCell.titleLabel.font = self.tabBar.layout.selectedTextFont; toCell.titleLabel.textColor = self.tabBar.layout.selectedTextColor ? self.tabBar.layout.selectedTextColor : self.tabBar.layout.normalTextColor; toCell.transform = CGAffineTransformIdentity; } }; if (animated) { [UIView animateWithDuration:self.tabBar.layout.animateDuration animations:^{ animateBlock(); }]; } else { animateBlock(); } }

还不支持设置字体的粗细，因为字体大小的变化是通过transform

是因为在pagerbarlayout文件中，有个地方作者写错了

• (void)transitionFromCell:(UICollectionViewCell )fromCell toCell:(UICollectionViewCell )toCell animate:(BOOL)animate { if (_pagerTabBar.countOfItems == 0) { return; } void (^animateBlock)() = ^{ if (fromCell) { fromCell.titleLabel.font = _normalTextFont; fromCell.titleLabel.textColor = _normalTextColor; fromCell.transform = CGAffineTransformMakeScale(_selectFontScale, _selectFontScale); } if (toCell) { toCell.titleLabel.font = _selectedTextFont;//原处为_normalTextFont toCell.titleLabel.textColor = _selectedTextColor ? _selectedTextColor : _normalTextColor; toCell.transform = CGAffineTransformIdentity; } }; if (animate) { [UIView animateWithDuration:_animateDuration animations:^{ animateBlock(); }]; }else{ animateBlock(); }

} 修改这个就好了
