【问题描述】:
当按下输入按钮时,我需要从警报视图中的文本字段中获取文本。
func inputMsg() {
var points = ""
var outOf = ""
var alertController = UIAlertController(title: "Input View", message: "Please Input Your Grade", preferredStyle: UIAlertControllerStyle.Alert)
let actionCancle = UIAlertAction(title: "Cancle", style: UIAlertActionStyle.Cancel) { ACTION in
println("Cacle")
}
let actionInput = UIAlertAction(title: "Input", style: UIAlertActionStyle.Default) { ACTION in
println("Input")
println(points)
println(outOf)
}
alertController.addAction(actionCancle)
alertController.addAction(actionInput)
alertController.addTextFieldWithConfigurationHandler({(txtField: UITextField!) in
txtField.placeholder = "I got"
txtField.keyboardType = UIKeyboardType.NumberPad
points = txtField.text
})
alertController.addTextFieldWithConfigurationHandler({(txtField: UITextField!) in
txtField.placeholder = "Out Of"
txtField.keyboardType = UIKeyboardType.NumberPad
outOf = txtField.text
})
presentViewController(alertController, animated: true, completion: nil)
}
