A collection of macros for use with auto layout. From this:

UIView *redView = [[UIView alloc]init];
    redView.translatesAutoresizingMaskIntoConstraints = NO;
    redView.backgroundColor = [UIColor redColor];
    [self.view addSubview:redView];

    [self.view addConstraints:@[
                                [NSLayoutConstraint
                                 constraintWithItem:redView
                                 attribute:NSLayoutAttributeCenterX
                                 relatedBy:NSLayoutRelationEqual
                                 toItem:self.view
                                 attribute:NSLayoutAttributeCenterX
                                 multiplier:1.0
                                 constant:0],
                                [NSLayoutConstraint
                                 constraintWithItem:redView
                                 attribute:NSLayoutAttributeCenterY
                                 relatedBy:NSLayoutRelationEqual
                                 toItem:self.view
                                 attribute:NSLayoutAttributeCenterY
                                 multiplier:1.0
                                 constant:0],
                                [NSLayoutConstraint
                                 constraintWithItem:redView
                                 attribute:NSLayoutAttributeWidth
                                 relatedBy:NSLayoutRelationEqual
                                 toItem:nil
                                 attribute:NSLayoutAttributeNotAnAttribute
                                 multiplier:1.0
                                 constant:300],
                                [NSLayoutConstraint
                                 constraintWithItem:redView
                                 attribute:NSLayoutAttributeHeight
                                 relatedBy:NSLayoutRelationEqual
                                 toItem:redView
                                 attribute:NSLayoutAttributeWidth
                                 multiplier:1.0
                                 constant:0],
                                ]];

to this:

    UIView *redView = [[UIView alloc]init];
    redView.translatesAutoresizingMaskIntoConstraints = NO;
    redView.backgroundColor = [UIColor redColor];
    [self.view addSubview:redView];

    [self.view addConstraints:@[
                                NSConstraintMakeCenter(redView, self.view),
                                NSConstraintMakeWidthAndHeightEqual(redView, 300)
                                ]];

Simply a way to make auto layout a bit less verbose. Some of the macros are made to only be used when adding constraints to an array as in the example, as there are two constraints needed to center an item in a view. So NSConstraintMakeCenter is only made to be passed into an array.

Installation


the prefered method is Cocoapods, just put pod 'TJLAutoLayoutMacros', '1.0.0' into your podfile. If you don't want to use cocoapods, just grab the files in the Source folder, drop them into your project and then #import "TJLAutoLayoutMacros.h" and start saving lines of code!
