Question

Is there a way to perform one code if either of two things happen? Specifically, I have 2 TextFields, and if any of them is empty, I want to popup UIAlertView when action is performed. I can set

if ([myTextField.text length] == 0) {
    NSLog(@"Nothing There");
    UIAlertView *nothing = [[UIAlertView alloc] initWithTitle:@"Incomplete" message:@"Please fill out all fields before recording" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles: nil];
    [nothing show];
    [nothing release];
}
if ([yourTextField.text length] == 0) {
    NSLog(@"Nothing For Name");
    UIAlertView *nothing = [[UIAlertView alloc] initWithTitle:@"Incomplete" message:@"Please fill out all fields before recording" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles: nil];
    [nothing show];
    [nothing release];
}

but if both are empty, it will pop up the statement 2 times.

How can I get it to popup only once if either, or both are empty?

Answer 1

You can combine the two conditions into a single if statement using the || (or) operator.

if (([myTextField.text length] == 0) || ([yourTextField.text length] == 0)) {
    NSLog(@"Nothing There");
    UIAlertView *nothing = [[UIAlertView alloc] initWithTitle:@"Incomplete" 
                                                      message:@"Please fill out all fields before recording" 
                                                     delegate:self 
                                            cancelButtonTitle:@"Ok" 
                                            otherButtonTitles:nil];
    [nothing show];
    [nothing release];
}
