In one of my application I need to split UIImage into multiple parts. The following was the code I am using to split. Here my problem is I am unable to load the image view by adding the image to UIImageView. - (void)viewDidLoad { UIImage* image = [UIImage imageNamed:@"monalisa.png"]; NSMutableArray* splitImages = [self splitImageIntoRects:(__bridge CGImageRef)(image)]; printf("\n count; %d",[splitImages count]); CALayer *layer = [splitImages objectAtIndex:5]; CGImageRef imgRef = (__bridge CGImageRef)(layer.contents); UIImage *img = [[UIImage alloc] initWithCGImage:imgRef]; UIImageView*

I have a UIPopoverController that contains a UITableViewController within a UINavigationController. Whenever a cell in this table view is pressed, I push yet another UITableViewController to my navigation Controller. I want to set the height of my second table view (let's say to 200) and adjust the size of the popover accordingly. I therefore first set the table view frame in viewDidAppear:(BOOL)animated and then call setPopoverContentSize:(CGSize)size animated:(BOOL)animated . Both heights are set to 200. The resizing works, but there are the following differences on the different iOS
