将 RPAnchor 添加到项目中

CocoaPods 是将 RPAnchor 添加到项目的推荐方式。

1、在项目 Podfile 中为 RPAnchor 添加一个 pod 条目

pod 'RPAnchor'

或者

pod 'RPAnchor', :git => 'https://github.com/dengfeng520/RPLayoutAnchor'

2、通过运行以下命令安装 pod

pod install

3、使用以下方式在需要的地方包含 RPAnchor

#import "UIView+Anchor.h"

用法

//---------------------
UIImageView *fristGrilImg = [[UIImageView alloc] init];
fristGrilImg.rp_addView(self.view)
.rp_safeAreaTop(20,self.view,rpSafeTop)
.rp_centerX(0,self.view,rpCenterX)
.rp_height(250)
.rp_multiplierWidth(1.45,fristGrilImg,rpHeight);
fristGrilImg.image = [UIImage imageNamed:@"one_gril"];
fristGrilImg.backgroundColor = UIColor.redColor;

//---------------------
UIImageView *secondGrilImg = [[UIImageView alloc] init];
[self.view addSubview:secondGrilImg];
secondGrilImg.rp_config()
.rp_top(10,fristGrilImg,rpBottom)
.rp_centerX(0,self.view,rpCenterX)
.rp_width(280)
.rp_multiplierHeight(1.46,secondGrilImg,rpWidth);
secondGrilImg.image = [UIImage imageNamed:@"second_gril"];
//--------------------- redView
UIView *redView = [[UIView alloc] init];
redView
.rp_addView(self.view)
.rp_safeAreaTop(0,self.view,rpSafeTop)
.rp_left(0,self.view,rpLeft)
.rp_right(0,self.view,rpRight)
.rp_safeAreaBottom(0,self.view,rpSafeBottom);
redView.backgroundColor = UIColor.redColor;

//--------------------- blueView
UIView *blueView = [[UIView alloc] init];
blueView
.rp_addView(redView)
.rp_top(70,redView,rpTop)
.rp_left(90,redView,rpLeft)
.rp_greaterWidth(80)
.rp_greaterHeight(80);
blueView.backgroundColor = UIColor.blueColor;

//--------------------- greenBtn
UIButton *greenBtn = [[UIButton alloc] init];
greenBtn
.rp_addView(redView)
.rp_centerX(0,redView,rpCenterX)
.rp_centerY(0,redView,rpCenterY)
.rp_size(180,45);
greenBtn.backgroundColor = UIColor.greenColor;

//--------------------- orangeView
UIView *orangeView = [[UIView alloc] init];
orangeView
.rp_addView(redView)
.rp_centerX(0,redView,rpCenterX)
.rp_multiplierWidth(0.7,redView,rpWidth)
.rp_top(20,blueView,rpBottom)
.rp_height(45);
orangeView.backgroundColor = UIColor.orangeColor;
