Question

I’m trying to do something I thought was going to be very simple but I can’t figure it out. I’m filling an array with objects like this in TableViewController:

if (indexPath.row == 0) {
    detailController.textArray = [[NSMutableArray alloc] initWithObjects:@"Text1", @"Text2", @"Text3", @"Text4", @"Text5", nil];
}

Then in the DetailController I added this action to make the label display the next object of the textArray:

- (IBAction)nexTextButtonPressed:(id)sender {
int i = 0;
if (i<[textArray count])
    i++;
    textLabel.text = [textArray objectAtIndex:i];
}

I connected the button in ib to the action with option Touch Down (tried some of the others too). Something isn’t working, the button jumps to the second object of the array but then it doesn’t work any more. What could be causing this and how to fix it?

Answer 1

int i = 0; is initialized inside the method, it will always be reinitialized to zero on every call which will not let you move forward from second object
