UIBezierPath Multiple Line Colors

Question

My attempt to draw UIBezierPath lines with different colors is failing me. All the lines change to the currently selected color. All my path and information are all stored i

Answer 1

The stroke/fill colors only affect the -stroke command. They don't affect the -appendPath: command. Paths don't contain per-segment color information.

If you need a multi-colored line you're going to need to stroke each color separately.

Answer 2

Set your stroke color (and what have you), then stroke, and then move to the next path:

- (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];
    }
}
