问题描述

我使用 Interface Builder (Xcode 4) 创建了一个宽 UIButton,添加了一个 5 字符的虚拟标题(例如 Click),然后以编程方式更改了标题文本.

I've created a wide UIButton with Interface Builder (Xcode 4), added in a dummy 5 character title (e.g. Click) and then changed the title text programmatically later.

奇怪的是标题文本的宽度似乎保持不变,所以如果我使用更长的文本(例如现在单击此处"),它会显示为:N...e"

Odd thing is the width of the title text seems to remain the same so, if I use a longer piece of text (e.g. "Now click here"), it appears like this: "N...e"

知道发生了什么吗?

更新:如果我在 IB 中使用一长串文本,它会居中.但是,一旦我以编程方式更改此文本,它就会显示为左对齐!

UPDATE: If I use a long line of text in IB it's centred. However, once I've programmatically-changed this text it appears left-aligned!

推荐答案

需要使用UIButton方法setTitle:forState:

[self.myButton setTitle:@"Correct New Title" forState:UIControlStateNormal];

因为这将正确更新按钮标签的大小和位置.仅使用 self.myButton.titleLabel.text = @"Wrong New Title"; 设置标题不会.

as this will correctly update the size and position of the buttons label. Where as just setting the title with self.myButton.titleLabel.text = @"Wrong New Title"; will not.
