WeView Example

// The most common way to use a stack layout is as a layout for a single subview.
WeView *container = [[WeView alloc] init];
[[[container addSubviewWithCustomLayout:label]
 setMargin:5]
 setSpacing:5];

// It can also be used to stack multiple views on top of each other.
WeView *container = [[WeView alloc] init];
[[[container addSubviewWithStackLayout:@[
     label,
     imageView,
     button,]
 setMargin:5]
 setSpacing:5];
