UIPickerView that looks like UIDatePicker but with seconds

Alrighty folks, here is the code to get hours/mins/secs in your UIPickerView. You can add 3 labels an strategically place them on the picker. I have attached a picture as well.

If you like the answer do rate it up! Good developers share knowledge not hide it like some people suggested. Have fun coding!

In your header .h file put this

@interface v1AddTableViewController : UITableViewController
{

    IBOutlet UIPickerView *pickerView;    
    NSMutableArray *hoursArray;
    NSMutableArray *minsArray;
    NSMutableArray *secsArray;

    NSTimeInterval interval;

}

@property(retain, nonatomic) UIPickerView *pickerView;
@property(retain, nonatomic) NSMutableArray *hoursArray;
@property(retain, nonatomic) NSMutableArray *minsArray;
@property(retain, nonatomic) NSMutableArray *secsArray;

in your .m file put this

@synthesize pickerView;
@synthesize hoursArray;
@synthesize minsArray;
@synthesize secsArray;
@synthesize interval;

- (void)viewDidLoad
{
    [super viewDidLoad];


    //initialize arrays
    hoursArray = [[NSMutableArray alloc] init];
    minsArray = [[NSMutableArray alloc] init];
    secsArray = [[NSMutableArray alloc] init];
    NSString *strVal = [[NSString alloc] init];

    for(int i=0; i<61; i++)
    {
        strVal = [NSString stringWithFormat:@"%d", i];

        //NSLog(@"strVal: %@", strVal);

        //Create array with 0-12 hours
        if (i < 13)
        {
            [hoursArray addObject:strVal];
        }

        //create arrays with 0-60 secs/mins
        [minsArray addObject:strVal];
        [secsArray addObject:strVal];
    }


    NSLog(@"[hoursArray count]: %d", [hoursArray count]);
    NSLog(@"[minsArray count]: %d", [minsArray count]);
    NSLog(@"[secsArray count]: %d", [secsArray count]);

}


//Method to define how many columns/dials to show
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
    return 3;
}


// Method to define the numberOfRows in a component using the array.
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent :(NSInteger)component 
{ 
    if (component==0)
    {
        return [hoursArray count];
    }
    else if (component==1)
    {
        return [minsArray count];
    }
    else
    {
        return [secsArray count];
    }

}


// Method to show the title of row for a component.
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{

    switch (component) 
    {
        case 0:
            return [hoursArray objectAtIndex:row];
            break;
        case 1:
            return [minsArray objectAtIndex:row];
            break;
        case 2:
            return [secsArray objectAtIndex:row];
            break;    
    }
    return nil;
}


-(IBAction)calculateTimeFromPicker
{

    NSString *hoursStr = [NSString stringWithFormat:@"%@",[hoursArray objectAtIndex:[pickerView selectedRowInComponent:0]]];

    NSString *minsStr = [NSString stringWithFormat:@"%@",[minsArray objectAtIndex:[pickerView selectedRowInComponent:1]]];

    NSString *secsStr = [NSString stringWithFormat:@"%@",[secsArray objectAtIndex:[pickerView selectedRowInComponent:2]]];

    int hoursInt = [hoursStr intValue];
    int minsInt = [minsStr intValue];
    int secsInt = [secsStr intValue];


    interval = secsInt + (minsInt*60) + (hoursInt*3600);

    NSLog(@"hours: %d ... mins: %d .... sec: %d .... interval: %f", hoursInt, minsInt, secsInt, interval);

    NSString *totalTimeStr = [NSString stringWithFormat:@"%f",interval];
