设置UITableView自动计算高度

设置tableview的样式

- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return 0.01;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return UITableViewAutomaticDimension;
}

设置cell布局的形式，垂直的方向布局上需要有距离底部的布局

Masonry优先级的布局

self.titleLbl.text = @"这里是第一，氨基酸的快乐建档立卡聚哆啦才打了加大了就大了；是将大量筹码的神色打满了吗电脑沙龙昆明大；里面CAD,看你的顺口溜你撒开了那上次；家里卡电视里，

    self.titleLbl.preferredMaxLayoutWidth = self.contentView.frame.size.width -120;
   [self.titleLbl setContentHuggingPriority:UILayoutPriorityRequired forAxis:UILayoutConstraintAxisVertical];
    [self.titleLbl mas_updateConstraints:^(MASConstraintMaker *make) {
        make.top.left.mas_equalTo(10);
        make.right.mas_equalTo(self.iconImgV.mas_left);
        make.bottom.mas_equalTo(self.contentView).offset(-10);
    }];
    [self.iconImgV mas_updateConstraints:^(MASConstraintMaker *make) {
        make.top.mas_equalTo(self.titleLbl);
        make.height.mas_equalTo(40);
        make.left.mas_equalTo(self.titleLbl.mas_right);
        make.width.mas_equalTo(40);
        make.right.mas_equalTo(self.subtitleLbl.mas_left);
    }];
    [self.subtitleLbl mas_updateConstraints:^(MASConstraintMaker *make) {
        make.right.mas_equalTo(self).offset(-10);
        make.top.bottom.mas_equalTo(self.titleLbl);
        make.left.mas_lessThanOrEqualTo(self.iconImgV.mas_right);
    }];
    [self.titleLbl setContentCompressionResistancePriority:UILayoutPriorityRequired forAxis:UILayoutConstraintAxisHorizontal];
    [self.iconImgV setContentCompressionResistancePriority:UILayoutPriorityRequired forAxis:UILayoutConstraintAxisHorizontal];
    [self.subtitleLbl setContentCompressionResistancePriority:UILayoutPriorityDefaultLow forAxis:UILayoutConstraintAxisHorizontal];

设置控件自适应高度

[self.titleLbl setContentHuggingPriority:UILayoutPriorityRequired forAxis:UILayoutConstraintAxisVertical];

设置控件的优先级

  

 [self.titleLbl setContentCompressionResistancePriority:UILayoutPriorityRequired forAxis:UILayoutConstraintAxisHorizontal]; 

 [self.iconImgV setContentCompressionResistancePriority:UILayoutPriorityRequired forAxis:UILayoutConstraintAxisHorizontal]; 

 [self.subtitleLbl setContentCompressionResistancePriority:UILayoutPriorityDefaultLow forAxis:UILayoutConstraintAxisHorizontal];
