Screenshot: - (void) renderPageAtIndex:(NSUInteger)index inContext:(CGContextRef)ctx { UIImage *image = [images objectAtIndex:index]; CGRect imageRect = CGRectMake(0, 0, image.size.width, image.size.height); CGAffineTransform transform = aspectFit(imageRect,

My most frequent bug has "Failed to determine navigation direction for scroll" for reason, any idea about how I could solve it? Here is the last Exception Backtrace: 1.

In iOS6 in the methods viewControllerAfterViewController and viewControllerBeforeViewController if I return nil (for block the page navigation when I am in the first or last page) the app crash with this exception: 'The number of view controllers provided (0) doesn't match the number required (1) for the requested transition' In iOS5 all works good. I had the same issue. I found that the cause was replacing the delegate on the UIPanGestureRecognizer of the UIPageViewController, a no-no really. The pan gesture recognizer was calling an undocumented method _gestureRecognizerShouldBegin: (note

I can't find a good solution to having the UIPageViewController preload the surrounding ViewControllers. Right now what happens is when the user starts to turn the page, nothing happens, the code calls - (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController and once its loaded thennnn it shows the animation. This takes too long and is not smooth. Anyone have a solution? Create a mutable container and when you show the first view, create the two viewController that would be needed if the user pages,

I want to pass data from a UIPageViewController to one of its child ViewControllers . I have a protocol set like so: protocol Delegate : class{ func protocolMethod(count:Int) } And in UIPageViewController : class PageVC : UIPageViewController{ var delegate : Delegate? var count : Int = 1 func classMethod(){ self.displayPageForIndex(5) //this controlls the tranistion to the child ViewController self.delegate?.protocolMethod(count : self.count) } } In the conforming child ViewController : class ChildVC : UIViewController , Delegate{ func protocolMethod(count : Int){ print(count) } override func
