swift中masonry的使用

let collectImage = UIImageView.init(image:UIImage.init(named:"shoucang_kong"))

collectImage.mas_makeConstraints { (make:MASConstraintMaker!) in

    make.right.mas_equalTo()(addButton.mas_left)

    make.top.mas_equalTo()(lineLabel.mas_bottom)?.offset()(5)

    make.width.equalTo()(20)

    make.height.equalTo()(20)

}
