Question

我有一个按钮，可以动态地将UITextField添加到xcode中的视图中。我想继续按下按钮，在视图下面添加尽可能多的文本字段，但我不知道该怎么做

到目前为止，这是我的代码：

@IBAction func buttonPressed(sender: AnyObject) {


    let sampleTextField = UITextField(frame: CGRectMake(20, 100, 300, 40))
    sampleTextField.placeholder = "Enter text here"
    sampleTextField.font = UIFont.systemFontOfSize(15)
    sampleTextField.borderStyle = UITextBorderStyle.RoundedRect
    sampleTextField.autocorrectionType = UITextAutocorrectionType.No
    sampleTextField.keyboardType = UIKeyboardType.Default
    sampleTextField.returnKeyType = UIReturnKeyType.Done
    sampleTextField.clearButtonMode = UITextFieldViewMode.WhileEditing;
    sampleTextField.contentVerticalAlignment = UIControlContentVerticalAlignment.Center
    sampleTextField.delegate = self
    self.view.addSubview(sampleTextField)
    print(sampleTextField.text!)

}

我知道这会添加一个texfield，按下按钮会重叠新的文本字段我想按下按钮并添加另一个

由于您需要下面的下一个文本字段，您需要修改函数中的y帧。

创建一个变量来保存y原点值，并在函数末尾添加它的值。

var yValue = 100

@IBAction func buttonPressed(sender: AnyObject) {
    let sampleTextField = UITextField(frame: CGRectMake(20, yValue, 300, 40))
    sampleTextField.placeholder = "Enter text here"
    sampleTextField.font = UIFont.systemFontOfSize(15)
    sampleTextField.borderStyle = UITextBorderStyle.RoundedRect
    sampleTextField.autocorrectionType = UITextAutocorrectionType.No
    sampleTextField.keyboardType = UIKeyboardType.Default
    sampleTextField.returnKeyType = UIReturnKeyType.Done
    sampleTextField.clearButtonMode = UITextFieldViewMode.WhileEditing;
    sampleTextField.contentVerticalAlignment = UIControlContentVerticalAlignment.Center
    sampleTextField.delegate = self
    self.view.addSubview(sampleTextField)
    print(sampleTextField.text!)

    yValue += 50
}

按下按钮添加多个uitextfields
