在Swift中将CollectionView作为子视图
我试图插入一个非常简单的collectionView作为Subview，但是无法获得正确的框架。我究竟做错了什么？请问你能帮帮我吗？
这是我的代码:
import UIKit
class ViewController: UIViewController {
var collectionView: UICollectionView!
@IBOutlet weak var testView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewDidLayoutSubviews() {
setupCollectionView()
}
func setupCollectionView() {
let layout = UICollectionViewFlowLayout()
collectionView = UICollectionView(frame: testView.frame, collectionViewLayout: layout)
collectionView.backgroundColor = UIColor.green
testView.addSubview(collectionView)
}
}
最佳答案
func setupCollectionView() {
let layout = UICollectionViewFlowLayout()
collectionView = UICollectionView(frame: CGRect(x: 0, y: 0, testView.frame.size.width, height: testView.frame.size.height), collectionViewLayout: layout)
collectionView.backgroundColor = UIColor.green
testView.addSubview(collectionView)
testView.clipsToBounds=true
}
