Question

In my mapkit app, I would be able to enable/disable programmatically buttons created via Interface Builder. The idea is enable a one or more button if a annotatios is selected, and disable if not. for example, in my, an action:

-(void)traceRoute:(id)sender{
 //trace route between user location and annotation selected
}

is defined in order to trace route between user location and annotation mapkit. In IB, defined a button and linked to that action, it works. But I do not understand how I can enable a button not defined programactically but in the interface builder. Any help is apreciated!

try this one

-(void)traceRoute:(id)sender{
     UIButton *button = (UIButton *)sender;
     [button setEnable:YES];
}
