UIStackView使用 （堆视图）

一基本使用

1创建多个子控件

for (int i = 0; i < 3; i++)

    {

        UIButton *imgBtn = [UIButton buttonWithType:UIButtonTypeCustom];

        imgBtn.backgroundColor = [UIColor redColor];

        [imgBtn setNormalImageWithName:@""];

        [imgBtns addObject:imgBtn];

    }

2创建堆控件

//创建堆控件

    UIStackView *stackView = [[UIStackView alloc] initWithArrangedSubviews:imgBtns];

    [self.view addSubview:stackView];

    [stackView mas_makeConstraints:^(MASConstraintMaker *make) {

        make.top.mas_equalTo(titleLabel.mas_bottom).offset(10);

        make.left.mas_equalTo(60);

        make.right.mas_equalTo(-60);

        make.height.mas_equalTo(80);

    }];

3设置属性

stackView.axis = UILayoutConstraintAxisHorizontal;

stackView.distribution = UIStackViewDistributionFillEqually;

stackView.spacing = 35;
