Research direction

Locate the Objective-C implementation of addArrangedSubview in FDStackView and compare its behavior with the iOS system method described in the issue. Reproduce the four-view example and verify that adding view2yellow again moves it to the end, while preserving the existing behavior for other arranged subviews.

Written by the indexing model from the issue text.

Description

stackView依次有4个arrangedSubview：view1red，view2yellow，view3green，view4orange

在系统方法中再次调用[stackView addArrangedSubview:view2yellow];view2yellow会被移动到最后面，view顺序变成view1red，view3green，view4orange，view2yellow

但是在iOS8 FDStackView中view2yellow的位置不会变动。
