我有一个UIButton，当按下时，会显示一个新的视图，用户可以在其中更改一些设置.当视图被驳回时，我想更新UIButton的标题/文本以反映新的状态.我打电话:
[myButton setTitle: @"myTitle" forState: UIControlStateNormal];
[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];
但它似乎永远不会改变IB中规定的原文/标题.
