A Mansory extension to generate native NSLayoutConstraint code from Mansory code.
Sometime I want to write constraints code easily but I dont want to add another dependency (such as writing a library). Generating native constraints can be handy.
Import MansoryGenerator:
#import "MasonryGenerator.h"Then add following line before your layout code:
[MasonryGenerator install];Now any mas_makeConstraints: or mas_updateConstraints: calls will print
the native constraints code on console.
UIView *superview = self.view;
superview.mas_key = @"superview";
UIView *view1 = UIView.new;
view1.mas_key = @"view1";
view1.backgroundColor = UIColor.greenColor;
view1.layer.borderColor = UIColor.blackColor.CGColor;
view1.layer.borderWidth = 2;
[superview addSubview:view1];
UIView *view2 = UIView.new;
view2.mas_key = @"view2";
view2.backgroundColor = UIColor.redColor;
view2.layer.borderColor = UIColor.blackColor.CGColor;
view2.layer.borderWidth = 2;
[superview addSubview:view2];
UIView *view3 = UIView.new;
view3.mas_key = @"view3";
[view1 mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.greaterThanOrEqualTo(superview.mas_top).offset(padding + 20);
make.left.equalTo(superview.mas_left).offset(padding);
make.bottom.equalTo(view3.mas_top).offset(-padding);
make.right.equalTo(view2.mas_left).offset(-padding);
make.width.equalTo(view2.mas_width);
make.height.equalTo(view2.mas_height);
make.height.equalTo(view3.mas_height);
}];Following code will be generated on console:
=====================================================
[superview addConstraint:[NSLayoutConstraint constraintWithItem:view1
attribute:NSLayoutAttributeTop
relatedBy:NSLayoutRelationGreaterThanOrEqual
toItem:superview
attribute:NSLayoutAttributeTop
multiplier:1.0
constant:30.0]];
[superview addConstraint:[NSLayoutConstraint constraintWithItem:view1
attribute:NSLayoutAttributeLeft
relatedBy:NSLayoutRelationEqual
toItem:superview
attribute:NSLayoutAttributeLeft
multiplier:1.0
constant:10.0]];
[superview addConstraint:[NSLayoutConstraint constraintWithItem:view1
attribute:NSLayoutAttributeBottom
relatedBy:NSLayoutRelationEqual
toItem:view3
attribute:NSLayoutAttributeTop
multiplier:1.0
constant:-10.0]];
[superview addConstraint:[NSLayoutConstraint constraintWithItem:view1
attribute:NSLayoutAttributeRight
relatedBy:NSLayoutRelationEqual
toItem:view2
attribute:NSLayoutAttributeLeft
multiplier:1.0
constant:-10.0]];
[superview addConstraint:[NSLayoutConstraint constraintWithItem:view1
attribute:NSLayoutAttributeWidth
relatedBy:NSLayoutRelationEqual
toItem:view2
attribute:NSLayoutAttributeWidth
multiplier:1.0
constant:0.0]];
[superview addConstraint:[NSLayoutConstraint constraintWithItem:view1
attribute:NSLayoutAttributeHeight
relatedBy:NSLayoutRelationEqual
toItem:view2
attribute:NSLayoutAttributeHeight
multiplier:1.0
constant:0.0]];
[superview addConstraint:[NSLayoutConstraint constraintWithItem:view1
attribute:NSLayoutAttributeHeight
relatedBy:NSLayoutRelationEqual
toItem:view3
attribute:NSLayoutAttributeHeight
multiplier:1.0
constant:0.0]];
=====================================================Masonry Generator find the views name by mas_key field, so always set the mas_key to the name of the view.
Important: You should only include MansoryGenerator during development!
