Question

I want to draw line in table view cell so that I can place textfield & switch in single cell. I increased the height of cell. How can I draw line in cell?

I have subclass of UIView which contains following code

 //Get the CGContext from this view
 CGContextRef context = UIGraphicsGetCurrentContext();
 //Set the stroke (pen) color
 CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor);
 //Set the width of the pen mark
 CGContextSetLineWidth(context, 1.0);

 // Draw a line
 //Start at this point
 CGContextMoveToPoint(context, 10.0, 30.0);

 //Give instructions to the CGContext
 //(move "pen" around the screen)
 CGContextAddLineToPoint(context, 310.0, 30.0);


 //Draw it
 CGContextStrokePath(context);

Then I have a tableViewController with grouped table style. In cellForRowAtIndexPath I have following code

//code to add textfield
DrawLineView *drawLine = [[DrawLineView alloc]init];
[cell addSubview:drawLine];
//code add switch

But it is not drawing any line. I can’t use 2 different cells. I have to Please help me. This is my first to deal with graphics i iphone. Thanks

Two things…
First, you usually don’t draw into the cell itself.

You normally draw into the content view. Sometimes it makes sense draw into the cell’s backgroundView or selectedBackgroundView.

[cell.contentView addSubview:drawLine];

Second, the default cell text labels cell.textLabel and cell.detailTextLabel have non-transparent background. Try setting their background colors to [UIColor clearColor].

Edit: one more thing: you need to set a proper frame for your drawLine

DrawLineView *drawLine = [[DrawLineView alloc]initWithFrame:cell.contentView.bounds];
