Use UIStackView directly in iOS6+

UI FDStackView

Overview

FDStackView

Use UIStackView as if it supports iOS6.

Problem

UIStackView is a very handy tool to build flow layout, but it's available only when iOS9+, we've found some great compatible replacements like OAStackView, but we want more:

Perfect downward compatible, no infectivity, use UIStackView directly as if it's shipped from iOS6.
Interface builder support, live preview.
Keep layout constraints as closely as UIStackView constructs.

Usage

Podfile

platform :ios, '7.0'
pod "FDStackView", "1.0"

Import nothing, learn nothing, it just works.

It will automatically replace the symbol for UIStackView into FDStackView at runtime before iOS9.

// Works in iOS6+, use it directly.
UIStackView *stackView = [[UIStackView alloc] init];
stackView.axis = UILayoutConstraintAxisHorizontal;
stackView.distribution = UIStackViewDistributionFill;
stackView.alignment = UIStackViewAlignmentTop;
[stackView addArrangedSubview:[[UILabel alloc] init]];
[self.view addSubview:stackView];

Interface Builder Support

Set Builds for option to iOS 9.0 and later to eliminate the version error in Xcode:

Now, use UIStackView as you like and its reactive options and live preview:

Requirements

Xcode 7+ (For interface builder supports and the latest Objective-C Syntax)
Base SDK iOS 9.0+ (To link UIStackView symbol in UIKit)

Versions

1.0.1 is the lastest version. We released it after we have used it in our official application. And it was successfully passed through the App Store's review. So you have no concern to use it.

iOS 8.3/8.4 phone5/5s/5c 卡顿严重，排渣找到了原因
(void)intrinsicContentSizeInvalidatedForChildView:(UIView *)childView { [self.distributionArrangement intrinsicContentSizeInvalidatedForItem:childView]; [self.alignmentArrangement intrinsicContentSizeInvalidatedForItem:childView]; } 上面这个更新布局的方法，在iOS7 不会调用，iOS8 会疯狂的调用，会导致界面卡顿很严重，然后注释掉这段代码卡顿消失，界面也没用什么影响，想问下，这个方法的作用？

iOS 8 crash

我在一个stackView中嵌套加了一个stackView, 嵌套的stackView动态添加imageView 在iOS8 crash, iOS9 正常。

The view hierarchy is not prepared for the constraint: <NSLayoutConstraint:0x7f838fe60440 UIStackView:0x7f838fd331d0.leading == UIImageView:0x7f838fc30c10.leading>
    When added to a view, the constraint's items must be descendants of that view (or the view itself). This will crash if the constraint needs to be resolved before the view hierarchy is assembled. Break on -[UIView _viewHierarchyUnpreparedForConstraint:] to debug.

exception break point 定位在

- (void)resetCanvasConnectionsEffect

中的

[self.canvas addConstraints:canvasConnectionConstraints];

Views do not respect 'Hidden' property in iOS 8 like they do in iOS9

One of the perks of UIStackView is that hidden views do not affect the layout. So if a view is marked as hidden it's as if it didn't exist. This behavior is absent from iOS8, where marking a view as hidden will still force it to occupy it's space.

在AutoLayout布局下的疑问

CAlayer 层是不支持AutoLayout 一般用Frame 或者bounds 来计算大小但是Autolayout布局确定的时机不对如何读出正确的frame ViewController 有个 -viewDidLayoutSubviewS 方法

那么问题来了 View怎么读?

从StackView中删除添加的subView

我在TableViewCell中使用StackView 重用时会出现重复添加view的问题，发现在addArrangedSubView 或 insertArrangedSubview:atIndex: 中调用了 [self addSubview:view] 或 [self insertSubview:view atIndex:stackIndex] 但并没有在removeArrangedSubview: 中删除添加的view

真机上不起作用，模拟器上起作用。

使用步骤： 1、项目中导入了FDStackView； 2、然后在一个xib文件中添加了一个StackView （已经正确添加约束） 3、在步骤2中创建的StackView中添加4个按钮,StackView的相关属性设置为： Axis: Horizontal Alignment: Center Distribution: Equal Spacing Spacing: 0

结果：在iPhone6 iOS8.2 和 iPhone5 iOS9.1 真机上只显示前三个按钮。在对应的模拟器上正常。请问是我哪里设置错误了吗？

addArrangedSubview逻辑错误

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。
