Masonary简单使用

Masonary

注意：（若想适配ipad 在general 中 选择 devices -> Universal）

引入Masonry 在github 上搜索 就可以了

引入头文件 @“Masonry”

在viewDidLoad 中写入

UIView *myView = [[UIView alloc] init];
myView.backgroundColor = [UIColor blueColor];
[self.view addSubview:myView];

[myView mas_makeConstraints:^(MASConstraintMaker *make) {
// 设置当前center和父视图的center一样
make.center.mas_equalTo(self.view);
// 设置当前视图的大小
make.size.mas_equalTo(CGSizeMake(300, 300));
}];

UIView *view1 = [[UIView alloc] init];
view1.backgroundColor = [UIColor redColor];
[myView addSubview:view1];

UIView *view2 = [[UIView alloc] init];
view2.backgroundColor = [UIColor yellowColor];
[myView addSubview:view2];

int padding = 10;

[view1 mas_makeConstraints:^(MASConstraintMaker *make) {
// 设置其位于父视图的Y的中心位置
make.centerY.mas_equalTo(myView.mas_centerY);
// 设置其左侧和父视图偏移10个像素
make.left.equalTo(myView).with.offset(padding);
// 设置其右侧和view2偏移10个像素
make.right.equalTo(view2.mas_left).with.offset(-padding);
// 设置高度
make.height.mas_equalTo(@120);
// 设置其宽度
make.width.equalTo(view2);
}];

[view2 mas_makeConstraints:^(MASConstraintMaker *make) {
make.centerY.mas_equalTo(myView.mas_centerY);
make.left.equalTo(view1.mas_right).with.offset(padding);
make.right.equalTo(myView).with.offset(-padding);
make.height.mas_equalTo(view1);
make.width.equalTo(view1);
}];
NSLog(@"%f %f",self.view.frame.size.width,self.view.frame.size.height);
