For vertical alignment:
对于垂直对齐：
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
Centered both vertically and horizontally:
垂直和水平居中：
theTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
theTextField.textAlignment = NSTextAlignmentCenter;
Centered within the parent container:
以父容器为中心：
YourTextFieldName.center = parentViewField.center;
