有一个表格 View 来显示电话联系人。我想在长按单元格时将电话号码和电子邮件发送到另一个 View Controller 。长按工作正常,但我无法将数据传递到另一个 View Controller 。
VC 1:
override func viewDidLoad() {
super.viewDidLoad()
let longPress = UILongPressGestureRecognizer(target: self, action: #selector(longpress))
tbMain.addGestureRecognizer(longPress)
}
表格 View 单元格的长按方法:
@objc func longpress(sender: UILongPressGestureRecognizer) {
if sender.state == UIGestureRecognizer.State.began {
let touchPoint = sender.location(in: tbMain)
if tbMain.indexPathForRow(at: touchPoint) != nil {
let cell = tbMain.dequeueReusableCell(withIdentifier: "testCell") as! NewContactCell
print("Long press Pressed:)")
self.actionVC = self.storyboard!.instantiateViewController(withIdentifier: "ActionsViewController") as? ActionsViewController
UIView.transition(with: self.view, duration: 0.25, options: [.transitionCrossDissolve], animations: {
self.view.addSubview( self.actionVC.view)
}, completion: nil)
}
}
}
VC 2:
internal var strPhoneNUmber : String!
internal var strEmail : String!
override func viewDidLoad() {
super.viewDidLoad()
print("Phone: \(strPhoneNUmber!)")
// Do any additional setup after loading the view.
}
最佳答案
从单元对象获取电话号码和电子邮件
self.actionVC.strPhoneNUmber = cell.strPhoneNUmber // get phone number from cell object
self.actionVC. strEmail = cell.strEmail // get email from cell object
代码就像
@objc func longpress(sender: UILongPressGestureRecognizer) {
if sender.state == UIGestureRecognizer.State.began {
let touchPoint = sender.location(in: tbMain)
if tbMain.indexPathForRow(at: touchPoint) != nil {
let cell = tbMain.dequeueReusableCell(withIdentifier: "testCell") as! NewContactCell
print("Long press Pressed:)")
self.actionVC = self.storyboard!.instantiateViewController(withIdentifier: "ActionsViewController") as? ActionsViewController
**self.actionVC.strPhoneNUmber = cell.strPhoneNUmber // get phone number from cell object
self.actionVC. strEmail = cell.strEmail // get email from cell object**
UIView.transition(with: self.view, duration: 0.25, options: [.transitionCrossDissolve], animations: {
self.view.addSubview( self.actionVC.view)
}, completion: nil)
}
}
}
