本文介绍如何在iOS开发中使用Autolayout为自定义视图设置约束，通过直接修改源码实现高度自适应，确保customview在不同屏幕尺寸下保持一致布局。

直接修改源码

- (void)setupConstraints
.....

if (_customView) {
        [self.contentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[customView]|" options:0 metrics:nil views:@{@"customView":_customView}]];
//        [self.contentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[customView]|" options:0 metrics:nil views:@{@"customView":_customView}]];
        CGFloat height = _customView.bounds.size.height;
        [self.contentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[customView(==height)]|" options:0 metrics:@{@"height":@(height)} views:@{@"customView":_customView}]];

    }

customview用auto layout 布局，给customview指定bounds
