[英]Don't dismiss uialertcontroller sheet with tap gesture outside dialog area in iOS
在我的iOS swift 3.0
應用程序中,我在當前的ViewController上展示了UIAlertController
表實例。 但是當我在表格的某個區域(變暗的半透明背景)之外點擊時,我不想解散該表格,因為我已經必須取消一個動作。 任何想法?
我有帶有更多按鈕的MGSwipeTableViewCell。 當用戶單擊該“更多”按鈕時,將執行以下代碼。
func onClickMore(for vmCell: VmCell) {
let sheet = UIAlertController(title: vmCell.vmItem?.vmNameWithoutIp, message: vmCell.vmItem?.ipAddress, preferredStyle: .actionSheet)
sheet.addAction(UIAlertAction(title: "Create Ticket", style: .default) { (action: UIAlertAction) in
})
sheet.addAction(UIAlertAction(title: "Start VM", style: .default) { (action: UIAlertAction) in
})
sheet.addAction(UIAlertAction(title: "Restart VM", style: .default) { (action: UIAlertAction) in
})
sheet.addAction(UIAlertAction(title: "Stop VM", style: .destructive) { (action: UIAlertAction) in
})
sheet.addAction(UIAlertAction(title: "Cancel", style: .cancel) { (action: UIAlertAction) in
})
present(sheet, animated: true) {
sheet.view.superview?.addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))
}
}
用於UIAlertController類型作為警報
您可以下載示例項目
將手勢識別器添加到alertController超級視圖中以處理用戶交互
self.present(alertController, animated: true, completion: {() -> Void in
alertController.view.superview?.addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil)
})
在那個動作上什么也不做
更新
let alertController = UIAlertController(title: "Do something", message: "With this", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "Done", style: .default) { action in
// perhaps use action.title here
})
self.present(alertController, animated: true, completion: {() -> Void in
alertController.view.superview?.addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))
})
用於UIAlertController類型為actionSheet
您可以下載示例項目
你可以用兩種方法
選項1
alert.view.superview.subviews[0] isUserInteractionEnabled = false
選項2
alert.view.superview?.subviews[0].addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))
例如
self.present(sheet, animated: true, completion: {() -> Void in
// sheet.view.superview?.subviews[0].isUserInteractionEnabled = false;
sheet.view.superview?.subviews[0].addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))
})
完整的代碼
let sheet = UIAlertController(title: "karthik", message: "check with", preferredStyle: .actionSheet)
sheet.addAction(UIAlertAction(title: "Create Ticket", style: .default) { (action: UIAlertAction) in
})
sheet.addAction(UIAlertAction(title: "Start VM", style: .default) { (action: UIAlertAction) in
})
sheet.addAction(UIAlertAction(title: "Restart VM", style: .default) { (action: UIAlertAction) in
})
sheet.addAction(UIAlertAction(title: "Stop VM", style: .destructive) { (action: UIAlertAction) in
})
sheet.addAction(UIAlertAction(title: "Cancel", style: .cancel) { (action: UIAlertAction) in
})
self.present(sheet, animated: true, completion: {() -> Void in
// sheet.view.superview?.subviews[0].isUserInteractionEnabled = false;
sheet.view.superview?.subviews[0].addGestureRecognizer(UITapGestureRecognizer(target: self, action: nil))
})
