UIKit

这本书主要是用来记录 UIKit 中控件的基本使用。

override func viewDidLoad() {
        super.viewDidLoad()

        collectionView.dataSource = self
        collectionView.registerClass(UICollectionViewCell.classForCoder(), forCellWithReuseIdentifier: "cell")

        navigationItem.rightBarButtonItem = UIBarButtonItem(title: "编辑", style: .Done, target: self, action: #selector(rightItemAction))


        title = "delete and add 动画"

        view.addSubview(collectionView)
        collectionView.snp_makeConstraints { (make) in
            make.edges.equalTo(self.view)
        }
    }
