Hi I have this problem declare that

IBOutlet UILabel * h1;
IBOutlet UILabel * h2;
IBOutlet UILabel * h3;
IBOutlet UILabel * h4;

and I want to fill the label with random numbers like this:

for (int i = 1; i <= 4; i + +) {
    int numerosr = random ()% 12;
    h [i]. text = [[NSString alloc] initWithFormat: @ "% 2.1f", numerosr]
}

but it makes error in h [1] which does not recognize h

Note that arrays in C start at the 0th index, e.g. h[0]. Also, you don't mention actually populating the array h with your label instances, so I can assume that the members of the array aren't valid. In fact, it's not clear that the array exists at all. You can't assume that because you have a variable h1, you have a variable h[1]: these are entirely independent in C. And therefore in Objective-C, too.
