Question

I have an NSMutableArray:

myButtons = [[NSArray alloc] initWithObjects:@"buttonOne", ... ,@"buttonNine",nil];

where each object is the name of a button object.

Now, I want to disable all the buttons, using a for loop.

I wrote the following:

for (id obj in myButtons)
    [obj setEnabled:NO];

but am getting an Error!
Am I doing something Wrong?

Answer 1

The problem is that you appear to be calling setEnabled on an NSString, not on a UIButton. Either fill your array with the UIButton objects, or get the buttons from their string names.
