当我在界面构建器上创建我的UIButton时,我放了一个像Button 1
这样的文本。
当我启动应用程序时,我以编程方式将文本更改为其他类似的内容:
btn1.titleLabel.text=@"Hello";
在按下按钮之前一切正常,它的默认文本是Button 1
。
我的目的是,如果文本已经以编程方式更改,则当我按下按钮时,它无法获取其默认文本值,我的意思是文本Hello
应该保留。我该怎么办? Thanx提前:))

不要直接更改textLabel,请使用setTitle:forState:而不是......

[btn1 setTitle:@"Hello" forState:UIControlStateNormal];
[btn1 setTitle: @"Hello" forState: UIControlStateSelected];
[btn1 setTitle: @"Hello" forState: UIControlStateHighlighted];
希望这有帮助。

[myButton setTitle: @"myTitle" forState: UIControlStateNormal];
use UIControlStateNormal to set your title.
there are couple of states that UIbuttons provide, you can have a look:
[myButton setTitle: @"myTitle" forState: UIControlStateApplication];
[myButton setTitle: @"myTitle" forState: UIControlStateHighlighted];
[myButton setTitle: @"myTitle" forState: UIControlStateReserved];
[myButton setTitle: @"myTitle" forState: UIControlStateSelected];
[myButton setTitle: @"myTitle" forState: UIControlStateDisabled];
