- Add support for view distribution (pingyourid)
- Add support for iOS 8 margin attributes (CraigSiemens)
- Add support for leading and trailing insets (montehurd)
- Add support for Cartage (erichoracek)
- Add aspect fit example (kouky)
As of iOS 8 there is active property of NSLayoutConstraint available, which allows to (de)activate constraint without searching closest common superview.
- Fixed compilation error when using objective-c++ (nickynick)
- Fixed bug in mas_updateConstraints (Rolken)
Was not checking that the constraint relation was equivalent SnapKit#65
- Added mas_remakeConstraints (nickynick)
Similar to mas_updateConstraints however instead of trying to update existing constraints it Removes all constraints previously defined and installed for the view, allowing you to provide replacements without hassle.
- Added Autoboxing for scalar/struct attribute values (nickynick)
Autoboxing allows you to write equality relations and offsets by passing primitive values and structs
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 these autoboxing macros are prefix with mas_
If you want the unprefixed version you need to add MAS_SHORTHAND_GLOBALS before importing Masonry.h (ie in your Prefix.pch)
Composites are great for defining multiple attributes at once. The following example makes top, left, bottom, right equal to superview.
make.edges.equalTo(superview).insets(padding);However if only three of the sides are equal to superview then we need to repeat quite a bit of code
make.left.equalTo(superview).insets(padding);
make.right.equalTo(superview).insets(padding);
make.bottom.equalTo(superview).insets(padding);
// top needs to be equal to `otherView`
make.top.equalTo(otherView).insets(padding);This change makes it possible to chain view attributes to improve readability
make.left.right.and.bottom.equalTo(superview).insets(padding);
make.top.equalTo(otherView).insets(padding);- Fixed Xcode auto-complete support (nickynick)
Breaking Changes
If you are holding onto any instances of masonry constraints ie
// in public/private interface
@property (nonatomic, strong) id<MASConstraint> topConstraint;You will need to change this to
// in public/private interface
@property (nonatomic, strong) MASConstraint *topConstraint;Instead of using protocols Masonry now uses an abstract base class for constraints in order to get Xcode auto-complete support see http://stackoverflow.com/questions/14534223/
- Added support for Mac OSX animator proxy (pfandrade)
self.leftConstraint.animator.offset(20);- Added setter methods for NSLayoutConstraint constant proxies like offset, centerOffset, insets, sizeOffset.
now you can update these values using more natural syntax
self.edgesConstraint.insets(UIEdgeInsetsMake(20, 10, 15, 5));can now be written as:
self.edgesConstraint.insets = UIEdgeInsetsMake(20, 10, 15, 5);- Added way to specify the same set of constraints to multiple views in an array (danielrhammond)
[@[view1, view2, view3] mas_makeConstraints:^(MASConstraintMaker *make) {
make.baseline.equalTo(superView.mas_centerY);
make.width.equalTo(@100);
}];which will update existing constraints if possible, otherwise it will add them. This makes it easier to use Masonry within the UIView - (void)updateConstraints method which is the recommended place for adding/updating constraints by apple.
