首先，您需要检索该值。做到这一点的基本方法是：

class ViewController: UIViewController, UICollectionViewDataSource, UITextFieldDelegate {
    @IBOutlet weak var collectionView: UICollectionView!

    var arr = [String]() //Original Array
    var dataSourceArr = arr //Filtered array based on textField content

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return dataSourceArr.count
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath)
        return cell
    }

    func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        self.reload(textField)
        return true
    }

    func reload(_ textField: UITextField) {
        if let text = textField.text {
            dataSourceArr = self.arr.filter({ $0.hasPrefix(text) }).sorted()
            collectionView.reloadData()
        }
    }
}

然后您将需要解码该值。

$u = $_GET['u'];

$ u_decoded现在将具有$ u的解码值。请记住，此代码假定url中始终存在“ u”，并且始终使用base64编码。

您可以将这段代码缩短为...

$u_decoded = base64_decode($u);

解码URL链接base64
