iphone - How not to let user choose a certain TabBarItem -


When a user wants to choose a certain UITebber item, I have to first see whether he can choose it. And if he can not, show a warning.

There is a delegate method, which is being picked up by choosing a user for a certain item, but it does not work when an item is disabled.

Thank you.

This is not a good UI design practice if a button is disabled, do not respond completely to user interaction needed. If this is not disabled, then something that he should do is the only case where there is a non-incompetent button, which displays an error / warning rather than taking the desired action, if it can be determined only in the last moment that action It is impossible to do
