ios - 如何根据文本长度增加 TextView 高度

Question

我想根据文本长度增加 textview 高度我尝试了一些代码，但结果像第一张图片一样，但我想像第二张图片一样。

代码:

- (void)viewDidLoad {
    [super viewDidLoad];

    textview.text = @"This returns the size of the rectangle that fits the given string with the given font. Pass in a size with the desired width and a maximum height, and then you can look at the height returned to fit the text. There is a version that lets you specify line break mode also.This returns the size of the rectangle that fits the given string with the given font. Pass in a size with the desired width and a maximum height, and then you can look at the height returned to fit the text. There is a version that lets you specify line break mode yes.";

    CGRect frame = textview.frame;
    frame.size.height = textview.contentSize.height;
    textview.frame = frame;
    textview.ScrollEnabled = NO;
}
