How can I dynamically hide a button from a view?

Question

I would like to dynamically hide a button in one of my views depending on a certain condition.

I tried adding some code to the view controller\'s -viewWillAppe

Answer 1

If all that one is trying to hide is the back button in the navigation bar, there is an easier way:

self.navigationItem.hidesBackButton = YES;

Quote from developer documentation:

hidesBackButton

A Boolean value that determines whether the back button is hidden.

@property(nonatomic, assign) BOOL hidesBackButton

Discussion

YES if the back button is hidden when this navigation item is the top item; otherwise, NO. The default value is NO.

Availability

Available in iPhone OS 2.0 and later.
