    <p>Sorry for noobish question about iPhone and Quartz programming. Just started my conversion from C++ to Objective-C :)</p> <p>So, I have such a class method</p> <pre><code>+(CGGradientRef)CreateGradient:(UIColor*)startColor endColor:(UIColor*)endColor { CGGradientRef result; CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGFloat locations[2] = {0.0f, 1.0f}; CGFloat startRed, startGreen, startBlue, startAlpha; CGFloat endRed, endGreen, endBlue, endAlpha; [endColor getRed:&amp;endRed green:&amp;endGreen blue:&amp;endBlue alpha:&amp;endAlpha]; [startColor getRed:&amp;startRed green:&amp;startGreen blue:&amp;startBlue alpha:&amp;startAlpha]; CGFloat componnents[8] = { startRed, startGreen, startBlue, startAlpha, endRed, endGreen, endBlue, endAlpha }; result = CGGradientCreateWithColorComponents(colorSpace, componnents, locations, 2); CGColorSpaceRelease(colorSpace); return result; } </code></pre> <p>and its usage.</p> <pre><code>-(void)FillGradientRect:(CGRect)area startColor:(UIColor *)startColor endColor:(UIColor *)endColor isVertical:(BOOL)isVertical { CGContextRef context = UIGraphicsGetCurrentContext(); UIGraphicsPushContext(context); CGGradientRef gradient = [Graphics CreateGradient:startColor endColor:endColor]; CGPoint startPoint, endPoint; if (isVertical) { startPoint = CGPointMake(CGRectGetMinX(area), area.origin.y); endPoint = CGPointMake(startPoint.x, area.origin.y + area.size.height); }else{ startPoint = CGPointMake(0, area.size.height / 2.0f); endPoint = CGPointMake(area.size.width, startPoint.y); } CGContextDrawLinearGradient(context, gradient, startPoint, endPoint, 0); CGGradientRelease(gradient); UIGraphicsPopContext(); } </code></pre> <p>everything works as expected. But, when I run the Analyze tool from Xcode 4, I'm getting a warning about memory leak in method <strong>CreateGradient</strong> for <code>result</code> variable. Well, I understand what's that about, but in my calling method I'm releasing the gradient object (<code>CGGradientRelease(gradient);</code>). So, who is wrong and how to make Analyze tool happy? </p> <p>Thx</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
