However if you're using Swift in your project, we recommend using [SnapKit](https://github.com/SnapKit/SnapKit) as it provides better type safety with a simpler API.** + +Masonry is a light-weight layout framework which wraps AutoLayout with a nicer syntax. Masonry has its own layout DSL which provides a chainable way of describing your NSLayoutConstraints which results in layout code that is more concise and readable. +Masonry supports iOS and Mac OS X. + +For examples take a look at the **Masonry iOS Examples** project in the Masonry workspace. You will need to run `pod install` after downloading. + +## What's wrong with NSLayoutConstraints? + +Under the hood Auto Layout is a powerful and flexible way of organising and laying out your views. However creating constraints from code is verbose and not very descriptive. +Imagine a simple example in which you want to have a view fill its superview but inset by 10 pixels on every side +```obj-c +UIView *superview = self.view; + +UIView *view1 = [[UIView alloc] init]; +view1.translatesAutoresizingMaskIntoConstraints = NO; +view1.backgroundColor = [UIColor greenColor]; +[superview addSubview:view1]; + +UIEdgeInsets padding = UIEdgeInsetsMake(10, 10, 10, 10); + +[superview addConstraints:@[ + + //view1 constraints + [NSLayoutConstraint constraintWithItem:view1 + attribute:NSLayoutAttributeTop + relatedBy:NSLayoutRelationEqual + toItem:superview + attribute:NSLayoutAttributeTop + multiplier:1.0 + constant:padding.top], + + [NSLayoutConstraint constraintWithItem:view1 + attribute:NSLayoutAttributeLeft + relatedBy:NSLayoutRelationEqual + toItem:superview + attribute:NSLayoutAttributeLeft + multiplier:1.0 + constant:padding.left], + + [NSLayoutConstraint constraintWithItem:view1 + attribute:NSLayoutAttributeBottom + relatedBy:NSLayoutRelationEqual + toItem:superview + attribute:NSLayoutAttributeBottom + multiplier:1.0 + constant:-padding.bottom], + + [NSLayoutConstraint constraintWithItem:view1 + attribute:NSLayoutAttributeRight + relatedBy:NSLayoutRelationEqual + toItem:superview + attribute:NSLayoutAttributeRight + multiplier:1 + constant:-padding.right], + + ]]; +``` +Even with such a simple example the code needed is quite verbose and quickly becomes unreadable when you have more than 2 or 3 views. +Another option is to use Visual Format Language (VFL), which is a bit less long winded. +However the ASCII type syntax has its own pitfalls and its also a bit harder to animate as `NSLayoutConstraint constraintsWithVisualFormat:` returns an array. + +## Prepare to meet your Maker! + +Heres the same constraints created using MASConstraintMaker + +```obj-c +UIEdgeInsets padding = UIEdgeInsetsMake(10, 10, 10, 10); + +[view1 mas_makeConstraints:^(MASConstraintMaker *make) { + make.top.equalTo(superview.mas_top).with.offset(padding.top); //with is an optional semantic filler + make.left.equalTo(superview.mas_left).with.offset(padding.left); + make.bottom.equalTo(superview.mas_bottom).with.offset(-padding.bottom); + make.right.equalTo(superview.mas_right).with.offset(-padding.right); +}]; +``` +Or even shorter + +```obj-c +[view1 mas_makeConstraints:^(MASConstraintMaker *make) { + make.edges.equalTo(superview).with.insets(padding); +}]; +``` + +Also note in the first example we had to add the constraints to the superview `[superview addConstraints:...`. +Masonry however will automagically add constraints to the appropriate view. + +Masonry will also call `view1.translatesAutoresizingMaskIntoConstraints = NO;` for you. + +## Not all things are created equal + +> `.equalTo` equivalent to **NSLayoutRelationEqual** + +> `.lessThanOrEqualTo` equivalent to **NSLayoutRelationLessThanOrEqual** + +> `.greaterThanOrEqualTo` equivalent to **NSLayoutRelationGreaterThanOrEqual** + +These three equality constraints accept one argument which can be any of the following: + +#### 1. MASViewAttribute + +```obj-c +make.centerX.lessThanOrEqualTo(view2.mas_left); +``` + +MASViewAttribute | NSLayoutAttribute +------------------------- | -------------------------- +view.mas_left | NSLayoutAttributeLeft +view.mas_right | NSLayoutAttributeRight +view.mas_top | NSLayoutAttributeTop +view.mas_bottom | NSLayoutAttributeBottom +view.mas_leading | NSLayoutAttributeLeading +view.mas_trailing | NSLayoutAttributeTrailing +view.mas_width | NSLayoutAttributeWidth +view.mas_height | NSLayoutAttributeHeight +view.mas_centerX | NSLayoutAttributeCenterX +view.mas_centerY | NSLayoutAttributeCenterY +view.mas_baseline | NSLayoutAttributeBaseline + +#### 2. UIView/NSView + +if you want view.left to be greater than or equal to label.left : +```obj-c +//these two constraints are exactly the same +make.left.greaterThanOrEqualTo(label); +make.left.greaterThanOrEqualTo(label.mas_left); +``` + +#### 3. NSNumber + +Auto Layout allows width and height to be set to constant values. +if you want to set view to have a minimum and maximum width you could pass a number to the equality blocks: +```obj-c +//width >= 200 && width <= 400 +make.width.greaterThanOrEqualTo(@200); +make.width.lessThanOrEqualTo(@400) +``` + +However Auto Layout does not allow alignment attributes such as left, right, centerY etc to be set to constant values. +So if you pass a NSNumber for these attributes Masonry will turn these into constraints relative to the view’s superview ie: +```obj-c +//creates view.left = view.superview.left + 10 +make.left.lessThanOrEqualTo(@10) +``` + +Instead of using NSNumber, you can use primitives and structs to build your constraints, like so: +```obj-c +make.top.mas_equalTo(42); +make.height.mas_equalTo(20); +make.size.mas_equalTo(CGSizeMake(50, 100)); +make.edges.mas_equalTo(UIEdgeInsetsMake(10, 0, 10, 0)); +make.left.mas_equalTo(view).mas_offset(UIEdgeInsetsMake(10, 0, 10, 0)); +``` + +By default, macros which support [autoboxing](https://en.wikipedia.org/wiki/Autoboxing#Autoboxing) are prefixed with `mas_`. Unprefixed versions are available by defining `MAS_SHORTHAND_GLOBALS` before importing Masonry. + +#### 4. NSArray + +An array of a mixture of any of the previous types +```obj-c +make.height.equalTo(@[view1.mas_height, view2.mas_height]); +make.height.equalTo(@[view1, view2]); +make.left.equalTo(@[view1, @100, view3.right]); +```` + +## Learn to prioritize + +> `.priority` allows you to specify an exact priority + +> `.priorityHigh` equivalent to **UILayoutPriorityDefaultHigh** + +> `.priorityMedium` is half way between high and low + +> `.priorityLow` equivalent to **UILayoutPriorityDefaultLow** + +Priorities are can be tacked on to the end of a constraint chain like so: +```obj-c +make.left.greaterThanOrEqualTo(label.mas_left).with.priorityLow(); + +make.top.equalTo(label.mas_top).with.priority(600); +``` + +## Composition, composition, composition + +Masonry also gives you a few convenience methods which create multiple constraints at the same time. These are called MASCompositeConstraints + +#### edges + +```obj-c +// make top, left, bottom, right equal view2 +make.edges.equalTo(view2); + +// make top = superview.top + 5, left = superview.left + 10, +// bottom = superview.bottom - 15, right = superview.right - 20 +make.edges.equalTo(superview).insets(UIEdgeInsetsMake(5, 10, 15, 20)) +``` + +#### size + +```obj-c +// make width and height greater than or equal to titleLabel +make.size.greaterThanOrEqualTo(titleLabel) + +// make width = superview.width + 100, height = superview.height - 50 +make.size.equalTo(superview).sizeOffset(CGSizeMake(100, -50)) +``` + +#### center +```obj-c +// make centerX and centerY = button1 +make.center.equalTo(button1) + +// make centerX = superview.centerX - 5, centerY = superview.centerY + 10 +make.center.equalTo(superview).centerOffset(CGPointMake(-5, 10)) +``` + +You can chain view attributes for increased readability: + +```obj-c +// All edges but the top should equal those of the superview +make.left.right.and.bottom.equalTo(superview); +make.top.equalTo(otherView); +``` + +## Hold on for dear life + +Sometimes you need modify existing constraints in order to animate or remove/replace constraints. +In Masonry there are a few different approaches to updating constraints. + +#### 1. References +You can hold on to a reference of a particular constraint by assigning the result of a constraint make expression to a local variable or a class property. +You could also reference multiple constraints by storing them away in an array. + +```obj-c +// in public/private interface +@property (nonatomic, strong) MASConstraint *topConstraint; + +... + +// when making constraints +[view1 mas_makeConstraints:^(MASConstraintMaker *make) { + self.topConstraint = make.top.equalTo(superview.mas_top).with.offset(padding.top); + make.left.equalTo(superview.mas_left).with.offset(padding.left); +}]; + +... +// then later you can call +[self.topConstraint uninstall]; +``` + +#### 2. mas_updateConstraints +Alternatively if you are only updating the constant value of the constraint you can use the convience method `mas_updateConstraints` instead of `mas_makeConstraints` + +```obj-c +// this is Apple's recommended place for adding/updating constraints +// this method can get called multiple times in response to setNeedsUpdateConstraints +// which can be called by UIKit internally or in your code if you need to trigger an update to your constraints +- (void)updateConstraints { + [self.growingButton mas_updateConstraints:^(MASConstraintMaker *make) { + make.center.equalTo(self); + make.width.equalTo(@(self.buttonSize.width)).priorityLow(); + make.height.equalTo(@(self.buttonSize.height)).priorityLow(); + make.width.lessThanOrEqualTo(self); + make.height.lessThanOrEqualTo(self); + }]; + + //according to apple super should be called at end of method + [super updateConstraints]; +} +``` + +### 3. mas_remakeConstraints +`mas_updateConstraints` is useful for updating a set of constraints, but doing anything beyond updating constant values can get exhausting. That's where `mas_remakeConstraints` comes in. + +`mas_remakeConstraints` is similar to `mas_updateConstraints`, but instead of updating constant values, it will remove all of its constraints before installing them again. This lets you provide different constraints without having to keep around references to ones which you want to remove. + +```obj-c +- (void)changeButtonPosition { + [self.button mas_remakeConstraints:^(MASConstraintMaker *make) { + make.size.equalTo(self.buttonSize); + + if (topLeft) { + make.top.and.left.offset(10); + } else { + make.bottom.and.right.offset(-10); + } + }]; +} +``` + +You can find more detailed examples of all three approaches in the **Masonry iOS Examples** project. + +## When the ^&*!@ hits the fan! + +Laying out your views doesn't always goto plan. So when things literally go pear shaped, you don't want to be looking at console output like this: + +```obj-c +Unable to simultaneously satisfy constraints.....blah blah blah.... +( + "=5000)]>", + "", + "", + "" +) + +Will attempt to recover by breaking constraint +=5000)]> +``` + +Masonry adds a category to NSLayoutConstraint which overrides the default implementation of `- (NSString *)description`. +Now you can give meaningful names to views and constraints, and also easily pick out the constraints created by Masonry. + +which means your console output can now look like this: + +```obj-c +Unable to simultaneously satisfy constraints......blah blah blah.... +( + "", + "= 5000>", + "", + "" +) + +Will attempt to recover by breaking constraint += 5000> +``` + +For an example of how to set this up take a look at the **Masonry iOS Examples** project in the Masonry workspace. + +## Where should I create my constraints? + +```objc +@implementation DIYCustomView + +- (id)init { + self = [super init]; + if (!self) return nil; + + // --- Create your views here --- + self.button = [[UIButton alloc] init]; + + return self; +} + +// tell UIKit that you are using AutoLayout ++ (BOOL)requiresConstraintBasedLayout { + return YES; +} + +// this is Apple's recommended place for adding/updating constraints +- (void)updateConstraints { + + // --- remake/update constraints here + [self.button remakeConstraints:^(MASConstraintMaker *make) { + make.width.equalTo(@(self.buttonSize.width)); + make.height.equalTo(@(self.buttonSize.height)); + }]; + + //according to apple super should be called at end of method + [super updateConstraints]; +} + +- (void)didTapButton:(UIButton *)button { + // --- Do your changes ie change variables that affect your layout etc --- + self.buttonSize = CGSize(200, 200); + + // tell constraints they need updating + [self setNeedsUpdateConstraints]; +} + +@end +``` + +## Installation +Use the [orsome](http://www.youtube.com/watch?v=YaIZF8uUTtk) [CocoaPods](http://github.com/CocoaPods/CocoaPods). + +In your Podfile +>`pod 'Masonry'` + +If you want to use masonry without all those pesky 'mas_' prefixes.
