Body
In iOS i'm trying to draw a clipped image. I want the clipping to be from one edge, curved to the farthest opposite edge. The below image illustrates in red, the border of the final image. In this example the curve goes from bottom left to top right. <img src="https://i.stack.imgur.com/e1ddA.png" alt="enter image description here"> Here is the code I currently wrote. My only problem is this method <code>bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:</code> does not curve to the extend i need. <pre><code>- (UIImage *)roundCorneredImage:(UIImage *)image radius:(CGFloat)radius { CGRect imageRect = CGRectZero; imageRect.size = image.size; UIGraphicsBeginImageContextWithOptions(imageRect.size, NO, [UIScreen mainScreen].scale); CGSize size = CGSizeMake(radius, radius); [[UIBezierPath bezierPathWithRoundedRect:imageRect byRoundingCorners:UIRectCornerBottomRight cornerRadii:size] addClip]; [image drawInRect:imageRect]; UIImage* result = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return result; } </code></pre> UPDATE: Heres the result I'm getting and my updated code. I need some further assistance... <img src="https://i.stack.imgur.com/fYRXm.png" alt="enter image description here"> <pre><code>UIBezierPath* bezier = [UIBezierPath bezierPath]; [bezier moveToPoint:CGPointMake(0, 0)]; [bezier addLineToPoint:CGPointMake(0, imageRect.size.height)]; [bezier addArcWithCenter:CGPointMake(imageRect.size.width / 2, imageRect.size.height / 2) radius:imageRect.size.height / 2 startAngle:M_PI / 2 endAngle:0 clockwise:NO]; [bezier addLineToPoint:CGPointMake(0, 0)]; [bezier addClip]; </code></pre>

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.
