Objective-c - iOS - hide/unhide label, textfield etc
提问by Firejs
I want to hide/unhide controls of a subview in a view. For example: When a button action occurs, some labels will become hidden then unhide on a subsequent button action and so on. I have implemented this functionality through Interface Builder. How can I do the same implementation programmatically?
我想在视图中隐藏/取消隐藏子视图的控件。例如：当一个按钮动作发生时，一些标签将被隐藏，然后在随后的按钮动作中取消隐藏等等。我已经通过 Interface Builder 实现了这个功能。如何以编程方式执行相同的实现？
I've tried
我试过了
[label1 hidden: true];
which hasn't worked for me.
这对我不起作用。

Use [self.view addsubview:self.label];to make the label visible.
使用[self.view addsubview:self.label];以使标签可见。
Use [self.label removefromSuperview];to remove from Superview.
用于[self.label removefromSuperview];从超级视图中删除。
