动态改变原型单元的高度

我正在尝试给我的标签添加一些文本。一旦文本大于指定的单元格高度。我希望细胞也能长得很高。我确实添加了以下代码来处理我的标签高度,但我不确定如何将其传播到我的细胞中。

    [super viewDidLoad];

    self.navigationItem.title = @"Scribbles";

    [scribble1 setTitle:@"Test 1" andBody:@"This is fun! This is fun! This is fun! This is fun! This is fun! This is fun! This is fun! This is fun! This is fun! This is fun! This is fun!" andImage:@"scribble.png"];
