Isfirstresponder swift问题
我得到一个“方法不会覆盖任何方法从它的超类”的第一个响应函数。我在网上查了这些,没有解决办法。你能帮我解决这个问题吗?这是代码。Isfirstresponder swift问题
public override func isFirstResponder() -> Bool { // Return true if any of `self`'s subviews is the current first responder.
// Needs to unwrap the IBOutlets otherwise IBInspectable is crashing when using CardTextField because IBOutlets
// are not initialized yet when IBInspectable engine runs.
guard let numberInputTextField = numberInputTextField, let monthTextField = monthTextField, let yearTextField = yearTextField, let cvcTextField = cvcTextField else {
return false
}
return [numberInputTextField, monthTextField, yearTextField, cvcTextField]
.filter({$0.isFirstResponder})
.isEmpty == false
}
以下是错误的图像

尝试更换此:
public override func isFirstResponder() -> Bool {
与此:
public override var isFirstResponder: Bool {
