objective-c - how - ios hide label programmatically

Objective-c-iOS-hide/unhide label, textfield etc (2)

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?

I've tried

[label1 hidden: true];

which hasn't worked for me.

Here is the answer:

[label1 setHidden:YES];

YES is Objective-C's version of true.

To hide a label:

self.yourlabelname.hidden = YES;
