For loop and if statement

Question

I am working with the following for loop:

for (int intPrjName = 0; intPrjName < [arrPrjName count]; intPrjName++)

I have a if/else stat

Answer 1

Your problem is a general programing problem. The simplest way is to just use a BOOL flag.

BOOL alertShown = NO;
for (int intPrjName = 0; intPrjName < [arrPrjName count]; intPrjName++) {
    if (something) {
        // . . .
    } else {
        if (!alertShown) {
            [self showAlert:intPrjName]; // Or something
            alertShown = YES;
        }
    }
}
