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], ]];
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.
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!
If you use TJLAutoLayoutMacros and you like it, feel free to let me know, [email protected]. If you have any issue or want to make improvements, submit a pull request.
