我在表格单元格中有一个UIButton作为地址。当我点击一次时;我打开谷歌地图的方向没有问题。现在,我想提供长手势选项,因此,如果您将手指放在按钮上,它将提供复制按钮标题中地址的选项。这是我的代码:
@IBOutlet weak var addressBtn: UIButton!
override func awakeFromNib() {
super.awakeFromNib()
addLongPressGesture()
}
@objc func longPress(gesture: UILongPressGestureRecognizer) {
if gesture.state == UIGestureRecognizer.State.began {
// how do I make it possible to copy the title of the button here? The address is already inserted as the title of the button
}
}
func addLongPressGesture(){
let longPress = UILongPressGestureRecognizer(target: self, action: #selector(longPress(gesture:)))
longPress.minimumPressDuration = 0.5
self.addressBtn.addGestureRecognizer(longPress)
}
这是一键点击即可毫无问题地转到地图的位置;所以我在这里没有问题,只是fyi:@IBAction func addressClicked(_ sender:Any){
if (UIApplication.shared.canOpenURL(NSURL(string:"comgooglemaps://")! as URL)) {
let street = order.street.replacingOccurrences(of: " ", with: "+")
let postalCode = order.postalCode.replacingOccurrences(of: " ", with: "+")
if street == "" || order.city == "" || order.province == "" || postalCode == ""{
UIApplication.shared.open(URL(string:"comgooglemaps://?saddr=&daddr=\(order.longitude),\(order.latitude)&directionsmode=driving")! as URL)
} else {
UIApplication.shared.open(URL(string:"comgooglemaps://?saddr=&daddr=+\(street),+\(order.city),+\(order.province),+\(postalCode)&directionsmode=driving")! as URL)
}
} else {
NSLog("Can't use comgooglemaps://")
}
}
使用
let text = addressBtn.currentTitle
或
let text = addressBtn.titleLabel?.text
我用以下代码弄清楚了:
//Create the AlertController and add Its action like button in Actionsheet
let actionSheetControllerIOS8: UIAlertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
actionSheetControllerIOS8.view.tintColor = AppColors.Blue
let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel) { _ in
}
actionSheetControllerIOS8.addAction(cancelActionButton)
let saveActionButton = UIAlertAction(title: "Open Google Map", style: .default)
{ _ in
if (UIApplication.shared.canOpenURL(NSURL(string:"comgooglemaps://")! as URL)) {
let street = order.street.replacingOccurrences(of: " ", with: "+")
let postalCode = order.postalCode.replacingOccurrences(of: " ", with: "+")
if street == "" || order.city == "" || order.province == "" || postalCode == ""{
UIApplication.shared.open(URL(string:"comgooglemaps://?saddr=&daddr=\(order.longitude),\(order.latitude)&directionsmode=driving")! as URL)
} else {
UIApplication.shared.open(URL(string:"comgooglemaps://?saddr=&daddr=+\(street),+\(order.city),+\(order.province),+\(postalCode)&directionsmode=driving")! as URL)
}
} else {
NSLog("Can't use comgooglemaps://")
}
}
actionSheetControllerIOS8.addAction(saveActionButton)
let deleteActionButton = UIAlertAction(title: "Copy Address", style: .default)
{ _ in
let address = "\(order.street), \(order.city), \(order.province), \(order.postalCode)"
let pasteBoard = UIPasteboard.general
pasteBoard.string = address
}
actionSheetControllerIOS8.addAction(deleteActionButton)
self.present(actionSheetControllerIOS8, animated: true, completion: nil)
}
