UIButton - 文本被截断 [英] UIButton - text truncated
问题描述
我创建了一个带有Interface Builder(Xcode 4)的宽UIButton,添加了一个虚拟的5个字符标题(例如Click),然后以编程方式稍后更改了标题文本。
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.
奇怪的是标题文字的宽度似乎保持不变所以,如果我使用较长的一段文字(例如现在点击这里),它看起来像这样: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"
知道发生了什么事吗?
更新:
如果我在IB中使用长行文字它的中心。但是,一旦我以编程方式更改了此文本,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
您需要使用 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。只需用 self.myButton.titleLabel.text = @错误的新标题设置标题;
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.
