I have rendered few UIImage objects using CGContextDrawImage. But when i apply rotation to the image, it is not applied and the view disappears. <code>code here</code> -(void )renderImage: (ItemView *)array { <pre><code> NSArray *selectedImages = self.slideView.selectedView.subviews; CGSize combinedSize = CGSizeMake(0, 0); for (int i = 0; i < [selectedImages count]; ++i) { CGSize sourceSize = [selectedImages[i] size]; NSLog(@"sdfsd %f %f ", sourceSize.width, sourceSize.height); combinedSize.width = MAX(combinedSize.width, sourceSize.width); combinedSize.height += sourceSize.height; } UIGraphicsBeginImageContextWithOptions(self.view.frame.size, NO, 0); CGContextRef context = UIGraphicsGetCurrentContext(); { CGContextTranslateCTM(context, 0, 768); CGContextScaleCTM(context, 1,-1); for (int i = 0; i < [selectedImages count]; ++i) { UIImageView *imageview = selectedImages[i]; UIImage *sourceImage = imageview.image; CGContextSaveGState(context); float radians1 = atan2(imageview.transform.a, imageview.transform.b); CGFloat angle = [(NSNumber *)[imageview valueForKeyPath:@"layer.transform.rotation.z"] floatValue]; printf("\n radians %f",radians1); printf("\n angle %f",angle); CGContextRotateCTM(context, radians(angle)); CGContextDrawImage(context, imageview.frame, imageview.image.CGImage); CGContextRestoreGState(context); //CGContextDrawImage(context, imageview.frame, imageview.image); } } UIImage *combinedImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIImageWriteToSavedPhotosAlbum(combinedImage, nil, nil, nil); </code></pre> } Thanks, Any help would be appreciated

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.
