iOS - 是否可以将标签/ TextView 重置为其在 Interface Builder 中定义的初始状态？

Question

在我的应用程序中，我有四个按钮和一些文本标签。标签中的文本是通过界面构建​​器定义的。我不善言辞，所以我希望下面的代码足够清楚，可以指出我正在尝试做什么。

- (void)viewDidLoad 
{

    [super viewDidLoad];

    //Default view loaded as defined in Interface Builder

}

- (IBAction)button_1_Pressed:(id)sender {

    // Programmatically Change text in Labels
}

- (IBAction)button_2_pressed:(id)sender {

    // Programmatically Change text in labels

}

- (IBAction)button_3_pressed:(id)sender {

    // Programmatically Change text in labels
}

- (IBAction)button_4_pressed:(id)sender {

    // Change text in labels back to the values when the view first loaded.
    // That is, to the text defined in Interface builder instead of changing 
    // it back programmatically. 
}

或者有没有办法在按下按钮 4 时重置/“重新启动” View ？

存储它，使用它。

-(void)viewDidLoad {
    self.originalText = self.textField.text;
}

-(void)restore {
    self.textField.text = self.originalText;
}
