Question

When I click a button Its title should be hide. I do’t want to set the title to empty string @””. So, How can i do this?

Answer 1

Why don’t you want to set the title to an empty string? Simply store the value in a local field and set the button’s title to @”” and everything will be fine.

In your .h:

NSString *someLocalField;

in your .m:

-(void)SomeButtonPressed {
  someLocalField = someButton.text;
  someButton.text = @"";
}

This way, if you ever need to restore the text of the button, you can do so:

someButton.text = someLocalField

If you want to do this for a bunch of buttons, you could always use an NSDictionary and associate the string values with the buttons.
