BYViewConstraint 0.6.0

Maintained by Moicci.

You want to add pod 'BYViewConstraint', '~> 0.6' similar to the following to your Podfile:

target 'MyApp' do
  pod 'BYViewConstraint', '~> 0.6'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try BYViewConstraint

BYViewConstraint is covenient class to implement the "Auto Layout" in Objective-C as below.

    UILabel* topLabel = [self addLabel:@"fullWidth/top" backColor:[UIColor redColor]];
    UILabel* bottomLabel = [self addLabel:@"fullWidth/bottom" backColor:[UIColor redColor]];
    UILabel* centerLabel = [self addLabel:@"centerX/Y" backColor:[UIColor blueColor]];
    UILabel* leftLabel = [self addLabel:@"left" backColor:[UIColor greenColor]];
    UILabel* rightLabel = [self addLabel:@"right" backColor:[UIColor greenColor]];

    BYViewConstraint* constraint = [[BYViewConstraint alloc] initWithSuperview:self.view];

    [constraint view:topLabel];
    [constraint fullWidth];
    [constraint top];
    [constraint height:50];

    [constraint view:bottomLabel];
    [constraint fullWidth];
    [constraint bottom];
    [constraint height:50];

    [constraint view:centerLabel];
    [constraint centerX];
    [constraint centerY];
    [constraint width:150];
    [constraint height:150];

    [constraint view:leftLabel];
    [constraint attachTop:topLabel];
    [constraint attachBottom:bottomLabel];
    [constraint left];
    [constraint attachRight:centerLabel];

    [constraint view:rightLabel];
    [constraint attachTop:topLabel];
    [constraint attachBottom:bottomLabel];
    [constraint attachLeft:centerLabel];
    [constraint right];

    [constraint apply];

Or in Swift.

let topLabel = addLabel("fullWidth/top", backColor:UIColor.redColor())
let bottomLabel = addLabel("fullWidth/bottom", backColor:UIColor.redColor())
let centerLabel = addLabel("centerX/Y", backColor:UIColor.blueColor())
let leftLabel = addLabel("left", backColor:UIColor.greenColor())
let rightLabel = addLabel("right", backColor:UIColor.greenColor())

let constraint = BYViewConstraint(superview:self.view)

constraint.view(topLabel)
    .fullWidth()
    .top()
    .height(50)

constraint.view(bottomLabel)
    .fullWidth()
    .bottom()
    .height(50)

constraint.view(centerLabel)
    .centerX()
    .centerY()
    .width(150)
    .height(150)

constraint.view(leftLabel)
    .attachTop(topLabel)
    .attachBottom(bottomLabel)
    .left()
    .attachRight(centerLabel)

constraint.view(rightLabel)
    .attachTop(topLabel)
    .attachBottom(bottomLabel)
    .attachLeft(centerLabel)
    .right()

constraint.apply()

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

for Swift user: see ViewController.swift in the sub-directory 'SwiftDemo'.
for Objective-C user: see ViewController.m in the sub-directory 'ObjcDemo'.

Installation

then install the pod.

pod install

for Swift Project

Add import "BYViewConstraint.h" into your Objective-C bridging header file (-Bridging-Header.h).

for Objective-C Project

Add #import "BYViewConstraint.h" in your .m file using BYViewConstraint.
