XEEViewConstraints is a project demonstrating the usage UIView+XEEConstraints category. This category is designed to simplify generation and application of Auto Layout constraints.
Example can be found in the app's root view controller class (ViewController). This category is a continuous work in progress, constantly increasing in methods count.
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
UIView* redView = [[UIView alloc] init];
redView.backgroundColor = [UIColor redColor];
[self.view addSubview:redView];
UIView* yellowView = [[UIView alloc] init];
yellowView.backgroundColor = [UIColor yellowColor];
[self.view addSubview:yellowView];
UIView* blueView = [[UIView alloc] init];
blueView.backgroundColor = [UIColor blueColor];
[self.view addSubview:blueView];
[self.view addConstraints:[redView setViewToFillSuperviewWidth]]; // setting width and x position
[self.view addConstraint:[redView setViewHeight:45.f]]; // setting height
[self.view addConstraint:[redView setViewAlignToSuperviewsVerticalCenter]]; // setting y position
[self.view addConstraint:[yellowView setViewCenterXToCenterXOf:redView withMargin:50.f]]; // setting x position
[self.view addConstraint:[yellowView setViewWidthToPercentageOfSuperviewWidth:0.2f]]; // setting width
[self.view addConstraint:[yellowView setViewHeightToHeightOf:redView]]; // setting heigth
[self.view addConstraint:[yellowView setViewAlignToSuperviewsBottomWithMargin:20.f]]; // setting y position
[self.view addConstraint:[blueView setViewAlignToSuperviewsRightWithMargin:10.f]];
[self.view addConstraint:[blueView setViewAlignToSuperviewsTopWithMargin:40.f]];
[self.view addConstraints:[blueView setViewWidth:60.f height:40.f]];
