vienvu89 / AddConstraint.swift

Last active February 1, 2016 10:30

Sometimes when add child view controller programmatically and just add subview fill all container. You have to add constraint again and again. This snip set code will help you add by one line of code.


	//Add constraint with top left right bottom is (0, 0, 0, 0)
	func addChildToContainer(parent container: UIView, child childView: UIView) {
	container.addSubview(childView)
	childView.translatesAutoresizingMaskIntoConstraints = false
	let views = Dictionary(dictionaryLiteral: ("childView", childView),("container", container))
	//Horizontal constraints
	let horizontalConstraints = NSLayoutConstraint.constraintsWithVisualFormat("H:\|[childView]\|", options: NSLayoutFormatOptions(rawValue: 0), metrics: nil, views: views)
	container.addConstraints(horizontalConstraints)

	self.tabBar.selectionIndicatorImage = [UIImage imageWithColor:[UIColor colorWithHexString:@"#040A0F" ] size:tabBarItemSize];


	NSInteger itemIndex = 2;
