How to get the sender's name of an NSButton

Question

I have several NSButtons that are attached to a single IBAction. I need to differentiate inside the method between the different buttons. I tried the following, but it doesn't work:

for (int i = 0; i++; i < 7) {
    if (sender == [NSString stringWithFormat:@"button%i", i+1]) 
    {
        NSLog(@"sender is button %i", i+1);
    }
}

How can this be made to work?

Answer 1

-(IBAction)buttonPressed:(id)sender
{
    switch ( [sender tag] )
    {
    case 1:
    //blah blah blah
    break;

    case 2:
    //blah blah etc.
    break;
    }
}

I'm averse to doing the work for you, but....

replace this line

if (sender == [NSString stringWithFormat:@"button%i", i+1]) 

with this line

if ([sender tag] == i) 

Note too that the format of your for loop is invalid:

for (int i = 0; i++; i < 7)

s/b:

for (int i = 0; i < 7; i++)
