uipagecontrol

Consider a UICollectionView with flow layout and paging enabled (by setting pagingEnabled to YES ). What would be the simplest way of obtaining the total number of pages? And where would be the most appropriate place to update the total number of pages (given that it might change if items are added/deleted, the size of the collection view changes or the layout changes)? The right answer should be: If the UICollectionView scrolls horizontally: int pages = ceil(self.collectionView.contentSize.width / self.collectionView.frame.size.width); If it scrolls vertically: int pages = ceil(self

When I needed to custom my UIPageControl I used this and this solution. Slightly modifying it for the new version of swift we have : class myPageControl: UIPageControl { var activeImage: UIImage! var inactiveImage: UIImage! required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) activeImage = UIImage(named: "active.png")! inactiveImage = UIImage(named: "inactive.png")! } func updateDots() { for i in 0 ..< self.subviews.count { let dot : UIImageView = imageViewForSubview(self.subviews[i]) if (i == self.currentPage) { dot.image = activeImage } else { dot.image = inactiveImage } } }

I want to add border color for dots in UIPageControl. Here is the small picture of it: I am able to put second dot by configuring it from XCode but I cannot make the first and third circles' inside empty. Is there a simple way to achieve that? Thanks :) That is not possible with the current properties available for UIPageControl . But you can do by integrating any third party page control which mimic the functionality of iOS UIPageControl . Other answer has applied a patch. I highly disagreed with that solution. Edited- Swift 3 & 4 extension to achieve the same result- extension UIPageControl

Is it possible to Increase the size of the indicator in UIPageViewController ? I have this: And my requirement is this: Scaling the page control will scale the dots, but will also scale the spacing in between them. pageControl.transform = CGAffineTransform(scaleX: 2, y: 2) If you want to keep the same spacing between dots, you'll need to transform the dots individually: pageControl.subviews.forEach { $0.transform = CGAffineTransform(scaleX: 2, y: 2) } However, if you do this in viewDidLoad , the transform has been reset by the time the view appears, so you should do this in

This question already has an answer here: How can I change the color of pagination dots of UIPageControl? 18 answers Is there a way to change page indicator dots color 10 answers I've seen apps (e.g. meebo) that have different indicators on UIPageControls instead of the default white circles. is there an easy way to do this? I've read the docs for UIPageControls and it seems that there is no methods to replace the images. You can achieve this by making the following steps: 1- Create a custom class that inherits from UIPageControl. 2- Assign this class to the required UIPageControl that you

I am making a simple slideshow view within my app. I'd like to link my UIPageControl to my UIScrollView. This shouldn't be too difficult, but I haven't been able to find a simple solution anywhere. Below is my code. HelpViewController.h #import <UIKit/UIKit.h> @interface HelpViewController : UIViewController{ } @end HelpViewController.m #import "HelpViewController.h" @interface HelpViewController () @end @implementation HelpViewController - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if
