How Can I Edit My Array's For Loop To Reflrect This?
pickerArray = [[NSMutableArray alloc] initWithCapacity:700];
    for ( int i = 1 ; i <= 1000 ; i = i++)
        [pickerArray addObject:[NSString stringWithFormat:@"%i", i]]

float weight = [[pickerArray objectAtIndex:row] intValue];
label.text = [NSString stringWithFormat:@"%f lb", weight];

pickerArray = [[NSMutableArray alloc] initWithCapacity:700];
for ( float i = 0.0 ; i <= 1000.0 ; i = i + 2.5)
{
    //[pickerArray addObject:[NSString stringWithFormat:@"%.1f", i]]
    [pickerArray addObject:[NSNumber numberWithFloat:i];
}


float weight = [[pickerArray objectAtIndex:row] floatValue];
label.text = [NSString stringWithFormat:@"%.1f", weight];

for ( float f = 0; f <= 1000; f = f + 2.5 )
    [pickerArray adObject:[NSString stringWithFormat:@"%.1f", f]];

[pickerArray adObject:[NSString stringWithFormat:@"%.1f", 2.5*i]];

float weight = [[pickerArray objectAtIndex:row] floatValue];

pickerArray = [[NSMutableArray alloc] initWithCapacity:1001];
for ( int i = 0 ; i <= 1000 ; ++i)
    [pickerArray addObject:[NSString stringWithFormat:@"%.1f", 2.5*i]]
