Masonry源码

在其官网上也进行了很多的介绍,在下面会写出我自己的一些见解.如果使用过iOS中系统的NSLayoutConstraints已经知道非常麻烦

如下代码就是系统的约束

<code class="language-objectivec hljs" style="display: block; padding: 0.5em; background-color: rgb(255, 255, 255); color: rgb(0, 0, 0); background-position: initial initial; background-repeat: initial initial;"><span class="hljs-built_in" style="color: rgb(102, 0, 102);">UIView</span> *superview = <span class="hljs-keyword" style="color: rgb(0, 0, 136);">self</span>;

[superview addSubview:view1];

安装

  1. 直接进入github进行源码下载
  2. 使用CocoaPod进行下载

 

使用

在上面介绍的时候我们看到系统要创建一个试图,距离上下左右都是10的这样一个约束需要写上很多代码,然而现在是使用Masonry的效果

<code class="language-objectivec hljs" style="display: block; padding: 0.5em; background-color: rgb(255, 255, 255); color: rgb(0, 0, 0); background-position: initial initial; background-repeat: initial initial;"><span class="hljs-built_in" style="color: rgb(102, 0, 102);">UIEdgeInsets</span> padding = <span class="hljs-built_in" style="color: rgb(102, 0, 102);">UIEdgeInsetsMake</span>(<span class="hljs-number" style="color: rgb(0, 102, 102);">10</span>, <span class="hljs-number" style="color: rgb(0, 102, 102);">10</span>, <span class="hljs-number" style="color: rgb(0, 102, 102);">10</span>, <span class="hljs-number" style="color: rgb(0, 102, 102);">10</span>);

[view1 mas_makeConstraints:^(MASConstraintMaker *make) {
    make<span class="hljs-variable" style="color: rgb(102, 0, 102);">.top</span><span class="hljs-variable" style="color: rgb(102, 0, 102);">.equalTo</span>(superview<span class="hljs-variable" style="color: rgb(102, 0, 102);">.mas_top</span>)<span class="hljs-variable" style="color: rgb(102, 0, 102);">.with</span><span class="hljs-variable" style="color: rgb(102, 0, 102);">.offset</span>(padding<span class="hljs-variable" style="color: rgb(102, 0, 102);">.top</span>); <span class="hljs-comment" style="color: rgb(136, 0, 0);">//with is an optional semantic filler</span>

}];
</code>

甚至我们这样写得更加简洁

<code class="language-objectivec hljs" style="display: block; padding: 0.5em; background-color: rgb(255, 255, 255); color: rgb(0, 0, 0); background-position: initial initial; background-repeat: initial initial;">[view1 mas_makeConstraints:^(MASConstraintMaker *make) {
    make<span class="hljs-variable" style="color: rgb(102, 0, 102);">.edges</span><span class="hljs-variable" style="color: rgb(102, 0, 102);">.equalTo</span>(superview)<span class="hljs-variable" style="color: rgb(102, 0, 102);">.with</span><span class="hljs-variable" style="color: rgb(102, 0, 102);">.insets</span>(padding);
}];</code>

接下来我们来观看下Masonry中的一些常用属性

<code class="language-objectivec hljs" style="display: block; padding: 0.5em; background-color: rgb(255, 255, 255); color: rgb(0, 0, 0); background-position: initial initial; background-repeat: initial initial;"><span class="hljs-comment" style="color: rgb(136, 0, 0);">// 左侧</span>

居中显示视图

<code class="language-objectivec hljs" style="display: block; padding: 0.5em; background-color: rgb(255, 255, 255); color: rgb(0, 0, 0); background-position: initial initial; background-repeat: initial initial;"><span class="hljs-built_in" style="color: rgb(102, 0, 102);">UIView</span> *myView = [[<span class="hljs-built_in" style="color: rgb(102, 0, 102);">UIView</span> alloc] init];

效果图

可以看到我们已经创建出一个位置居中,并且视图大小为300×300

提醒一下,以下代码等价

<code class="language-objectivec hljs" style="display: block; padding: 0.5em; background-color: rgb(255, 255, 255); color: rgb(0, 0, 0); background-position: initial initial; background-repeat: initial initial;">make<span class="hljs-variable" style="color: rgb(102, 0, 102);">.left</span><span class="hljs-variable" style="color: rgb(102, 0, 102);">.equalTo</span>(myView)<span class="hljs-variable" style="color: rgb(102, 0, 102);">.with</span><span class="hljs-variable" style="color: rgb(102, 0, 102);">.offset</span>(padding);
<span class="hljs-comment" style="color: rgb(136, 0, 0);">// 等价于</span>
make<span class="hljs-variable" style="color: rgb(102, 0, 102);">.left</span><span class="hljs-variable" style="color: rgb(102, 0, 102);">.equalTo</span>(myView<span class="hljs-variable" style="color: rgb(102, 0, 102);">.mas_left</span>)<span class="hljs-variable" style="color: rgb(102, 0, 102);">.with</span><span class="hljs-variable" style="color: rgb(102, 0, 102);">.offset</span>(padding);</code>

也就是说默认情况下括号里面只写了视图的时候,其自动帮你添加当前masxxx(代表前面你需要设置的约束的位置).比如上面两行代码设置的make.left,当括号里面只写了myView的时候,会自动追加为myView.mas_left。

 

多个视图间隔相同

注意下面设置宽度的时候是传递的数组,这样才能让多个视图进行等距离显示

One thought on “Masonry简单使用”

  1. 一名来自xxx公司的iOS开发者 说道:

    博主,给你合并下多个视图相隔相同的方法:
    __weak typeof(self) weakSelf = self;

    UIView * tempView = [[UIView alloc]init];
    NSInteger count = 10;//设置一排view的个数
    NSInteger margin = 10;//设置相隔距离
    NSInteger height = 50;//设置view的高度
    for (int i = 0; i < count; i ++) {
    UIView * view = [[UIView alloc]init];
    view.backgroundColor = [UIColor brownColor];
    [self.view addSubview:view];
    if (i == 0) {
    [view mas_makeConstraints:^(MASConstraintMaker *make) {
    make.left.equalTo(weakSelf.view).offset(margin);
    make.centerY.equalTo(weakSelf.view);
    make.height.mas_equalTo(height);
    }];
    }
    else if (i == count – 1){
    [view mas_makeConstraints:^(MASConstraintMaker *make) {
    make.right.equalTo(weakSelf.view).offset(-margin);
    make.left.equalTo(tempView.mas_right).offset(margin);
    make.centerY.equalTo(tempView);
    make.height.equalTo(tempView);
    make.width.equalTo(tempView);
    }];
    }
    else{
    [view mas_makeConstraints:^(MASConstraintMaker *make) {
    make.left.equalTo(tempView.mas_right).offset(margin);
    make.centerY.equalTo(tempView);
    make.height.equalTo(tempView);
    make.width.equalTo(tempView);
    }];
    }
    tempView = view;
    [view layoutIfNeeded];
    }
