How To Install?

• Copy to your project

​ Copy JustUiKit folder from the demo project to your project

• Installation with CocoaPods

  CocoaPods is a dependency manager for Objective-C/Swift, which automates and simplifies the process of using 3rd-party libraries like JustUiKit in your projects. You can install it with the following command:

  $ sudo gem install cocoapods

  To integrate JustUiKit into your Xcode project using CocoaPods, specify it in your Podfile:

  platform :ios, '8.0'
  pod 'JustUiKit', '~> 0.2.1'
  

  ​Then, run the following command:

  $ pod install

Quick Start

JustLinearLayout

A Layout that arranges its children in a single column or a single row. The direction of the row can be set by orientation. You can also specify gravity, which specifies the alignment of all the child elements by set gravity or specify that specific children grow to fill up any remaining space in the layout by setting the weight member of LinearLayoutParams. The default orientation is horizontal.

Gravity & Margin & Orientation

You can set Gravity to make Views be layouted at a specify space of parentView. Also set Margin will remain spaces in the four directions of the View. In default, LinearLayout layout children in Horizontal direction, and you can change it to Veritcal.

Example:

let parentView = JustLinearLayout(frame: UIScreen.main.bounds, orientation: .Vertical)
let params = LinearLayoutParams(
                width: LayoutParams.WRAP_CONTENT,
                height: LayoutParams.WRAP_CONTENT)
let centerParams = LinearLayoutParams(params)
centerParams.layoutGravity = Gravity.Horizontal.getValue()

let marginParams = LinearLayoutParams(params)
marginParams.topMargin = 10

parentView.addView(createView(), centerParams)
parentView.addView(createView(), marginParams)

Padding & weight

With the Padding in four directions, you can remain inner space of the view. And Weight describes how the child views are positioned. Defaults to Gravity.TOP | Gravity.LEFT. If this layout has a VERTICAL orientation, this controls where all the child views are placed if there is extra vertical space. If this layout has a HORIZONTAL orientation, this controls the alignment of the children.

See Gravity to get more details.

Example:

let parentView = JustLinearLayout(frame: UIScreen.main.bounds, orientation: .Vertical)
let params = LinearLayoutParams(
                width: LayoutParams.WRAP_CONTENT,
                height: LayoutParams.WRAP_CONTENT)
params.weight = 1
let paddingParams = LinearLayoutParams(params)
paddingParams.paddingTop = 10
parentView.addView(createView(), params)
parentView.addView(createView(), paddingParams)

JustFrameLayout

FrameLayout is designed to block out an area on the screen to display a single item. Generally, FrameLayout should be used to hold a single child view, because it can be difficult to organize child views in a way that's scalable to different screen sizes without the children overlapping each other. You can, however, add multiple children to a FrameLayout and control their position within the FrameLayout by assigning gravity to each child, using the layoutGravity.

Overlap on left

if don't use any Margin or Padding to change view's position. All the Views will be add like stack and overlap on the left|top of the screen.

Example:

let parentView: JustFrameLayout = JustFrameLayout(width:MATCH_PARENT, height:MATCH_PARENT)
let params: FrameLayoutParams = JustFrameLayoutParams(width: WRAP_CONTENT, height: WRAP_CONTENT)
parentView.addView(createView(rgb:0xE4E1D8), params)
parentView.addView(createView(rgb:0x89A49D), params)
parentView.addView(createView(rgb:0x877B6B), params)

Layout With Gravity

You can use horizontal and vertical gravity. Also You can use like left|bottom, center_horizontal|center_vertical to use them at the same time.

See Gravity to get more details.

Example:

let parentView: FrameLayout = FrameLayout(width:MATCH_PARENT, height:MATCH_PARENT)
let params: FrameLayoutParams = FrameLayoutParams(width: WRAP_CONTENT, height: WRAP_CONTENT)

let b_l = FrameLayoutParams(params)
b_l.layoutGravity = Gravity.BOTTOM | Gravity.TOP
let c_r = FrameLayoutParams(params)
c_r.layoutGravity = Gravity.CENTER_HORIZONTAL | Gravity.RIGHT
parentView.addView(createView(rgb:0xE4E1D8), b_l)
parentView.addView(createView(rgb:0x89A49D), c_r)
parentView.addView(createView(rgb:0x877B6B), params)

JustRelativeLayout

A Layout where the positions of the children can be described in relation to each other or to the parent.

Note that you cannot have a circular dependency between the size of the RelativeLayout and the position of its children. For example, you cannot have a RelativeLayout whose height is set to WRAP_CONTENT and a child set to ALIGN_PARENT_BOTTOM.

In RelativeLayout, you can use all the Margin,Padding and Gravity. Also You can use some Align functions. Such as, if a view is alignLeftTo, its left edge will be set equal to the anchor view. You can use a set of functions like leftOf, rightOf, bottomOf set the current view to the left of anchor view.

// view1 view2 view3 view4 view5
let params = RelativeLayoutParams.generateDefaultParams()
let params1 = RelativeLayoutParams(params)
params1.centerInHorizontal()
let params2 = RelativeLayoutParams(params)
params2.bottomTo(view4)
params2.topMargin = xxx
let params3 = RelativeLayoutParams(params)
param3.alignRightTo(view1)
let params4 = RelativeLayoutParams(params)
params4.centerInParent()
let params5 = RelativeLayoutParams(params)
params5.alignParentBottom()
// add view to parent

Rule in RelativeLayout

Gravity

Must be one or more (separated by '|') of the following constant values.
