Getting error with NSTimer

Im getting an expected expression error in the line below that is : 

 for (int i = [timeArray count] - 1; i >= 0; i-) {

specifically the i-) its messing with things and I don;t know what to do. I am trying to build a stopwatch app. Here's the entire statement:

//

- (void)showTime {
int hours = 0;
int minutes = 0;
int seconds = 0;
int hundredths = 0;
NSArray *timeArray = [NSArray arrayWithObjects:self.hun.text, self.sec.text, self.min.text, self.hr.text, nil];

for (int i = [timeArray count] - 1; i >= 0; i-) {
    int timeComponent = [[timeArray objectAtIndex:i] intValue];
    switch (i) {
        case 3:
            hours = timeComponent;
            break;
        case 2:
            minutes = timeComponent;
            break;
        case 1:
            seconds = timeComponent;
            break;
        case 0:
            hundredths = timeComponent;
            hundredths++;
            break;

        default:
            break;
    }

}

i-) is not legal syntax. The compiler expects a literal or variable after the -.

You probably meant to write i-- or --i. Both of these statements subtract one from i. There is a difference between them, but they are both logically correct for your loop.
