xcode 你能在IB中建立一个按钮并以编程方式移动它吗？

Can you establish a button in IB and move it programmatically?

提问by emachine

I have a button set up in IB. I have an IBOutlet set up and the onscreen object linked to it. Is there a way to programmatically change that buttons position and/or size? I know you can change the title and some things but I don't see how to change it's position or size.

我在 IB 中设置了一个按钮。我有一个 IBOutlet 设置和链接到它的屏幕对象。有没有办法以编程方式更改按钮位置和/或大小？我知道您可以更改标题和某些内容，但我不知道如何更改它的位置或大小。

Thank You.

谢谢你。

You can change the frameof the button (or any UIView).

您可以更改frame按钮（或任何 UIView）的 。

CGRect frame = [button frame];
frame.origin.x += 100;  // change the location
frame.size.width += 100;  // change the size
[button setFrame:frame];

You simply create a new frame for it i.e. myButton.frame = CGRectMake(0,0,123,412);and it moves to that new frame. The order for CGRectMake is (origin x, origin y, width, height).

您只需为它创建一个新框架，即myButton.frame = CGRectMake(0,0,123,412);它会移动到该新框架。CGRectMake 的顺序是（原点 x，原点 y，宽度，高度）。
