If you're using interface builder there's an "enabled" option.
如果您使用的是界面构建器,则有一个“启用”选项。

button.enabled = NO;
button.enabled = NO;
you can set the button property to no and if interface builder you can uncheck the property
您可以将按钮属性设置为 no,如果界面生成器您可以取消选中该属性
回答by W.Baird
button.enabled = true;
this will ENABLE the button
这将启用按钮
button.enabled = false;
this will DISABLE the button. If you want to hide the button you can do this
这将禁用按钮。如果你想隐藏按钮,你可以这样做
button.alpha = 0.0;
and if you want to show the button once more you can do this.
如果你想再次显示按钮,你可以这样做。
button.alpha = 1.0
Hope this helps! :)
