我最近开始在我正在开发的应用程序中使用 IQKeyboardManager,除了一个小问题外,它运行得非常好。当键盘出现时,我的文本视图的高度会增加(这会使文本视图上升),我知道这一点,因为每次单击文本视图时我都会打印文本视图的高度。这是我的文本视图的代码:
// Setup text view
func setupTextView() {
// Placeholder text and color
startStoryTextView.textColor = .gray
startStoryTextView.text = "Type here"
startStoryTextView.backgroundColor = .red
// Add some padding to the text insde the text view
startStoryTextView.textContainerInset = UIEdgeInsets(top: 15, left: 10, bottom: 15, right: 10)
startStoryTextView.font = UIFont(name: "PatrickHand-Regular", size: 23)
startStoryTextView.layer.cornerRadius = 25
popUp.addSubview(startStoryTextView)
addTextViewConstraints()
}
// Add the constraints to the text view
func addTextViewConstraints() {
startStoryTextView.translatesAutoresizingMaskIntoConstraints = false
startStoryTextView.leadingAnchor.constraint(equalTo: popUp.leadingAnchor, constant: 3).isActive = true
startStoryTextView.trailingAnchor.constraint(equalTo: popUp.trailingAnchor, constant: -3).isActive = true
startStoryTextView.topAnchor.constraint(equalTo: popUp.topAnchor, constant: 3).isActive = true
//startStoryTextView.heightAnchor.constraint(equalToConstant: 589).isActive = true
startStoryTextView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor, constant: -70).isActive = true
}
// Add constraints to the pop up view
func addPopUpConstraints() {
popUp.translatesAutoresizingMaskIntoConstraints = false
popUp.widthAnchor.constraint(equalToConstant: view.frame.width).isActive = true
popUp.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: 10).isActive = true
popUp.topAnchor.constraint(equalTo: view.topAnchor, constant: 200).isActive = true
popUp.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
view.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
}
指定文本视图的高度可以解决这个问题,但是当应用程序在不同分辨率的其他设备上使用时会产生另一个问题。
// To print the height of the text view every time the user clicks on the text view
func textViewDidBeginEditing(_ textView: UITextView) {
print(startStoryTextView.frame.height)
}
