我有一个 UIPickerView 我想改变框架的大小.似乎无论我想要它有多小，都设置了我不能小于的最小尺寸.我看过其他关于这个的帖子，但它们已经很旧了，现在代码也大不相同了.我知道如何调整选择器视图中行的高度和宽度，但不知道框架本身.即使在 Frame Inspector 中，无论我改变高度和宽度，它都不会小于特定尺寸.

I have a UIPickerView that I would like to change the size of frame. It seems that no matter how small I want it there is set minimum size that I can't go smaller than. I have seen other posts about this but they are very old and the code is much different now. I know how to adjust the height and width of the rows in the picker view but not the frame itself. Even in the Frame Inspector no matter what I change on the height and width it will not go smaller than a certain size.

推荐答案

你不能在不做一些奇怪的黑客攻击的情况下改变 UIPickerView 的大小.该类是为特定尺寸编写的，如果您修改它以更改大小，则会导致奇怪的问题.

You can't change the size of a UIPickerView without doing strange hacks. The class is written for specific dimensions and if you do hack it to change the size it leads to weird issues.

我建议您使用 iCarousel 库 来实现自定义选择器视图.

I would suggest you use the iCarousel library to implement a custom picker view.
