UIBezierPath Multichannel Colors

My attempt to draw UIBezierPath lines with different colors does not allow me. All lines change to the currently selected color. My whole path and information is stored in NSMutableArray named pathInfo. In the path information, I fall into an array containing Path, Color, Width and Type of line. This works great, except that all lines refer to any color chosen by the user. I would appreciate any help!

- (void)drawRect:(CGRect)rect {
    UIBezierPath *drawPath = [UIBezierPath bezierPath];
    drawPath.lineCapStyle = kCGLineCapRound;
    drawPath.miterLimit = 0;

    for (int i = 0; i < [pathInfo count]; i++){
        NSArray *row = [[NSArray alloc] initWithArray:[pathInfo objectAtIndex:i]];
        NSLog(@"Path: %@",[row objectAtIndex:0]);
        NSLog(@"Color: %@",[row objectAtIndex:1]);
        NSLog(@"Width: %@",[row objectAtIndex:2]);
        NSLog(@"Type: %@",[row objectAtIndex:3]);

        //width
        drawPath.lineWidth = [[row objectAtIndex:2] floatValue];

        //color
        [[row objectAtIndex:1] setStroke];

        //path
        [drawPath appendPath:[row objectAtIndex:0]];

    }

   UIBezierPath *path = [self pathForCurrentLine];
    if (path)
     [drawPath appendPath:path];

   [drawPath stroke];
}

- (UIBezierPath*)pathForCurrentLine {
    if (CGPointEqualToPoint(startPoint, CGPointZero) && CGPointEqualToPoint(endPoint, CGPointZero)){
        return nil;
    }

    UIBezierPath *path = [UIBezierPath bezierPath];
    [path moveToPoint:startPoint];
    [path addLineToPoint:endPoint];

    return path;

The colors of the stroke / fill only affect the team -stroke. They do not affect the team -appendPath:. Outlines do not contain color information for each segment.

( ), stroke, :

- (void)drawRect:(CGRect)rect
{
    for (int i = 0; i < [pathInfo count]; i++){
        NSArray *row = [[NSArray alloc] initWithArray:[pathInfo objectAtIndex:i]];

        NSLog(@"Path: %@",[row objectAtIndex:0]);
        NSLog(@"Color: %@",[row objectAtIndex:1]);
        NSLog(@"Width: %@",[row objectAtIndex:2]);
        NSLog(@"Type: %@",[row objectAtIndex:3]);

        UIBezierPath *path = [row objectAtIndex:0];

        path.lineCapStyle = kCGLineCapRound;
        path.miterLimit = 0;

        //width
        path.lineWidth = [[row objectAtIndex:2] floatValue];

        //color
        [[row objectAtIndex:1] setStroke];

        //path
        [path stroke];
    }

    UIBezierPath *path = [self pathForCurrentLine];
    if (path)
    {
        // set the width, color, etc, too, if you want
        [path stroke];
    }
