去除cell的下划线需要根据tableview的方法
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.showsVerticalScrollIndicator = NO;
self.tableView.bounces = NO;
去除cell的点击效果需要用到cell的方法
cell.selectionStyle = UITableViewCellSelectionStyleNone;
//让label的内容为2行
_conetentLable.numberOfLines = 2;
//图片整个填充
_iconView.contentMode = UIViewContentModeScaleToFill;

自定义cell
+ (instancetype)cellWithTableView:(UITableView*)tableView;
+ (instancetype)cellWithTableView:(UITableView *)tableView {
static NSString *reuseID = @”cell”;
ADNewdateilsCell *cell = [tableView dequeueReusableCellWithIdentifier:reuseID];
if (cell == nil) {
cell = [[ADNewdateilsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseID];
}
return cell;
}
//重写cell初始化方法
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
[self setupUI];
}
return self;
}
- (void)setupUI {
UILabel *describeLabel = [UILabel new];
describeLabel.text = @”上地东路”;
describeLabel.font = [UIFont systemFontOfSize:14];
describeLabel.textAlignment = NSTextAlignmentLeft;
[self.contentView addSubview:describeLabel];
self.describeLabel = describeLabel;

UIImageView *iconImageView = [UIImageView new];iconImageView.image = [UIImage imageNamed:@"婚纱详情_07"];[self.contentView addSubview:iconImageView];self.iconImageView = iconImageView;

}
//布局子控件
- (void)layoutSubviews {
[_iconImageView autoAlignAxis:ALAxisHorizontal toSameAxisOfView:_iconImageView.superview];
[_iconImageView autoPinEdge:ALEdgeLeft toEdge:ALEdgeLeft ofView:_iconImageView.superview withOffset:15];
//设置大小
[_iconImageView autoSetDimensionsToSize:CGSizeMake(16, 16)];

[_describeLabel autoAlignAxis:ALAxisHorizontal toSameAxisOfView:_describeLabel.superview];[_describeLabel autoPinEdge:ALEdgeLeft toEdge:ALEdgeRight ofView:_iconImageView withOffset:15];

}

PureLayout 的使用
常见的方法 ：
1, 忽略底部设置高度
[nameLabel autoPinEdgesToSuperviewEdgesWithInsets:UIEdgeInsetsMake(94, 25, 0, 0) excludingEdge:ALEdgeBottom];
[nameLabel autoSetDimension:ALDimensionHeight toSize:21];
2,设置控件跟控件之间的距离
[texfield autoPinEdge:ALEdgeLeft toEdge:ALEdgeLeft ofView:texfield.superview withOffset:30];
3,设置控件的大小
[modifyButton autoSetDimensionsToSize:CGSizeMake(12, 15)];
4,设置跟父控件水平垂直居中
[modifyButton autoAlignAxisToSuperviewAxis:ALAxisVertical];

利用PureLayout画cell下面的线 只要在cell中调用这个方法就可以了
// 画线
if ((indexPath.section == 0 && indexPath.row == 2) || (indexPath.section == 1 &&indexPath.row == 1)) {
[self congfigueLineView:cell.contentView edgeInset:UIEdgeInsetsZero excludingEdge:ALEdgeTop];
}else if(indexPath.row == 0){
[self congfigueLineView:cell.contentView edgeInset:UIEdgeInsetsZero excludingEdge:ALEdgeBottom];
}
[self congfigueLineView:cell.contentView edgeInset:UIEdgeInsetsMake(0, 20, 0, 20) excludingEdge:ALEdgeTop];
//画线
- (void)congfigueLineView:(UIView*)contentView edgeInset:(UIEdgeInsets)edgeInset excludingEdge:(ALEdge)edge{
UIView *line = [UIView new];
[contentView addSubview:line];
[line autoPinEdgesToSuperviewEdgesWithInsets:edgeInset excludingEdge:edge];
[line autoSetDimension:ALDimensionHeight toSize:0.5f];
line.backgroundColor = [UIColor lightGrayColor];
}

//让滚动条滚动
- (void)setUpLineViewConstaintX:(CGFloat)scale{
_constraintX.constant = _lineView.width * scale;
//强行更新约束
[self setNeedsLayout];
}
在scrollView代理方法中实现让滚动条滚动
- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
CGFloat offset = scrollView.contentOffset.x;
if (offset > SCREEN_WIDTH * 0.5) {
_headerView.sellerButton.selected = YES;
_headerView.userButton.selected = NO;
}else{
_headerView.userButton.selected = YES;
_headerView.sellerButton.selected = NO;
}
[_headerView setUpLineViewConstaintX:offset/SCREEN_WIDTH];
}
