问题 I wrote a custom pinch gesture recognizer for my ScrollView's zooming, and I handle pinch touches in a method in my view controller.

问题 I have a UIScrollView over an image at the bottom of my app that acts as a dock with icons that can be scrolled through horizontally. Instead of the harsh edges of the UIScrollView, I would like the icons to fade out for a more aesthetically pleasing look.

问题 I have a RootViewController with a UIScrollView (boardScrollView). This has a UIImageView as subview to create a board (boardImage). I can zoom in and out, works fine. Also scrolling works fine! Now, I want to drag & drop other UIImageViews (Tiles) into and out of the ScrollView. I have subclassed UIImageView to TileImageView and overridden methods touchesBegan, touchesMoved and touchesEnded. The drag & drop works fine on the superview. But I want to be able to drop the Tiles on the

问题 I am making an image slider that slides automatically every 2 seconds. The code I have wrote moves immediately to the next image without the slide animation, I want to fix it somehow by showing the scrollview scrolling, this is my code: var imagesArray = [UIImage]() static var i = 0 override func viewDidLoad() { super.viewDidLoad() imagesArray = [image1, image2, image3, image4] for i in 0..<imagesArray.count{ let imageview = UIImageView() imageview.image = imagesArray[i] imageview.contentMode

During the test it documents the percentage complete and after it changes to showing if any problems have been detected. The color of the text also changes to indicate bad/ok/good.
