    <p>I am using the following piece of code to create a gradient background for a UITableViewCell. While this works perfectly for a plain table cell, the gradient only appears at the left and right corners of the grouped table cell. It is as if the gradient is applied then, the cell is drawn on top of it. </p> <p>Can someone suggest a modification to the code, that would work well with grouped table cell? Or is there a completely different way of doing this?</p> <pre><code>- (void)drawRect:(CGRect)rect { CGContextRef c = UIGraphicsGetCurrentContext(); CGGradientRef myGradient; CGColorSpaceRef myColorspace; size_t num_locations = 2; CGFloat locations[2] = {0.0, 1.0}; CGFloat components[8] = {0.8f, 0.8f, 0.8f, 1.0f, // Bottom Colour: Red, Green, Blue, Alpha. 0.9f, 0.9f, 0.9f, 1.0}; // Top Colour: Red, Green, Blue, Alpha. myColorspace = CGColorSpaceCreateDeviceRGB(); myGradient = CGGradientCreateWithColorComponents (myColorspace, components, locations, num_locations); CGColorSpaceRelease(myColorspace); CGPoint startPoint, endPoint; startPoint.x = 0.0; startPoint.y = self.frame.size.height; endPoint.x = 0.0; endPoint.y = 0.0; CGContextDrawLinearGradient (c, myGradient, startPoint, endPoint, 0); const CGFloat topSepColor[] = { 0.8f, 0.8f, 0.8f, 1.0f }; // Cell Seperator Colour - Top CGGradientRelease(myGradient); CGContextSetStrokeColor(c, topSepColor); CGContextMoveToPoint(c, 0.0, 0.0); CGContextSetLineWidth(c, 1.0); CGContextSetLineCap(c, kCGLineCapRound); CGContextAddLineToPoint(c, self.frame.size.width, 0.0); CGContextStrokePath(c); const CGFloat bottomSepColor[] = { 0.5f, 0.5f, 0.5f, 1.0f }; // Cell Seperator Colour - Bottom CGContextSetStrokeColor(c, bottomSepColor); CGContextMoveToPoint(c, 0.0, self.frame.size.height); CGContextSetLineWidth(c, 1.0); CGContextSetLineCap(c, kCGLineCapRound); CGContextAddLineToPoint(c, self.frame.size.width, self.frame.size.height); CGContextStrokePath(c); [[UIColor blackColor] set]; } </code></pre> <p>Thanks for your help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
