    <p>You can add this method to a UIView category and reuse as needed. It applies a linear black gradient from "theColor" to transparent to the given view.</p> <p>You should have QuartzCore.framework in your project in order to use the CAGradientLayer object.</p> <pre><code>+ (void)addLinearGradientToView:(UIView *)theView withColor:(UIColor *)theColor transparentToOpaque:(BOOL)transparentToOpaque { CAGradientLayer *gradient = [CAGradientLayer layer]; //the gradient layer must be positioned at the origin of the view CGRect gradientFrame = theView.frame; gradientFrame.origin.x = 0; gradientFrame.origin.y = 0; gradient.frame = gradientFrame; //build the colors array for the gradient NSArray *colors = [NSArray arrayWithObjects: (id)[theColor CGColor], (id)[[theColor colorWithAlphaComponent:0.9f] CGColor], (id)[[theColor colorWithAlphaComponent:0.6f] CGColor], (id)[[theColor colorWithAlphaComponent:0.4f] CGColor], (id)[[theColor colorWithAlphaComponent:0.3f] CGColor], (id)[[theColor colorWithAlphaComponent:0.1f] CGColor], (id)[[UIColor clearColor] CGColor], nil]; //reverse the color array if needed if(transparentToOpaque) { colors = [[colors reverseObjectEnumerator] allObjects]; } //apply the colors and the gradient to the view gradient.colors = colors; [theView.layer insertSublayer:gradient atIndex:0]; } </code></pre> <p>Please note that you should have the backgroundColor of theView set to clearColor so that it doesn't interfere with the gradient. Also, for the results shown in the screenshot, the transparentToOpaque flag should be YES. </p>

    1. COI have done what you said exactly but the code has no effect, I called the method like this in viewDidLoad: [UIView addLinearGradientToView:self.testView withColor:[UIColor redColor] transparentToOpaque:YES]; of course I created the category without problems. I'm testing on iOS 6 simulator and QuartzCore framework is also added and imported to this View's page.

    2. COI forgot to set the layer's origin to (0,0). I've edited the post to reflect the change. You can play around with the alpha components in the colors array to give a "non linear" gradient if you want.

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.
