Try this method

- (void)removeAllLabels
{
    for (UIView *view in self.view.subviews)
    {
        if ([view isKindOfClass:[UILabel class]])
        {
            [view removeFromSuperview];
        }
    }
}

You could do this before adding the new label:

[image.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];

This will instruct any subviews to remove themselves.

However, this depends on the fact that a UIImageView doesn't have any subviews in the current version of iOS, which may not always be true. It'd be better to actually keep track of these labels and specifically remove them when you're finished with them, or even reuse them instead of making new ones every time.
