PureLayout(轻量级自动布局)

直接整理用法

1.设置高度宽度

[view1 autoSetDimension:ALDimensionHeight toSize:70.0];

[view1 autoSetDimension:ALDimensionWidth toSize:70.0];

2.相对于父视图

ALEdgeInsets defInsets = ALEdgeInsetsMake(20.0,20.0,20.0,20.0);

[view1 autoPinEdgesToSuperviewEdgesWithInsets:defInsets];

相当于下面的写法

[view1 autoPinEdgeToSuperviewEdge:ALEdgeLeft withInset:20.0];

[view1 autoPinEdgeToSuperviewEdge:ALEdgeRight withInset:20.0];

[view1 autoPinEdgeToSuperviewEdge:ALEdgeTop withInset:20.0];

[view1 autoPinEdgeToSuperviewEdge:ALEdgeBottom withInset:20.0];

相对于父视图除了某一个

[view1 autoPinEdgesToSuperviewEdgesWithInsets:defInsets excludingEdge:ALEdgeBottom];

3.两个视图的相对位置

[view2 autoPinEdge:ALEdgeTop toEdge:ALEdgeBottom ofView:view1 withOffset:defInsets.bottom];

4.同宽同高

[@[view1,view2]autoMatchViewsDimension:ALDimensionHeight];可以设置多种

[view1 autoMatchDimension:ALDimensionHeight toDimension:ALDimensionHeight ofView:view2];

5.水平对齐垂直对齐

[view1 autoAlignAxis:ALAxisHorizontal toSameAxisOfView:view2];

[view1 autoAlignAxis:ALAxisVertical toSameAxisOfView:view2];
