Improve the smoothness of a basic WPF storyboard animation

阅读更多关于 Improve the smoothness of a basic WPF storyboard animation

I've been playing around with some basic WPF Storyboard animation and it looks quite blurry, it's Ok up to a certain speed then really degrades into blurryness. Is there anyway I can get it to look smoother? - increase the framerate somehow or maybe double buffer the animation? I've tried setting the objects to CacheMode="BitmapCache" but this seems to have little effect. Does anyone have any ideas please? <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Width

Could not find a storyboard named 'Main' in bundle NSBundle?

阅读更多关于 Could not find a storyboard named 'Main' in bundle NSBundle?

问题 While trying to localize a SpriteKit game i suddenly started getting the error: "Could not find a storyboard named 'Main' in bundle NSBundle" I wasn't use a storyboard, and i think i actually deleted the file when i first started developing the game. 'Main storyboard file base name' was set to 'Main' (was set before as well when it worked and there was no storyboard). I deleted that entry and now the program just executes the AppDelegate file and essentially stops. What's missing where before

The storyboard is automatically copied to the new project

阅读更多关于 The storyboard is automatically copied to the new project

问题 I have a project in Xcode, lets name it A , in which I have a story board and several views. I only need part of project A . Hence, I made a new project, B , and made a new UIViewController , with xib, and copied the two UIViews from project A to B. It looks like this now, where RPM Display and Speed Display are copied (by dragging from xib) from A to B. AnalogDisplayContainer belongs to the class PD_AnalogDisplayContainer , and we have two outlets in class PD_AnalogDisplayContainer :

问题 I've already read the post Passing data to views using Storyboards, but still have problem with calling methods: Now I have AViewController and BViewController , both connected with Storyboard (no XIBs). In BViewController : -(void)doSth:(int)num; So how can I call the doSth: method in AViewController ? The old way like [bViewController doSth:123]; don't work because I can't get the instance of BViewController in the Storyboard. Thanks. Peak 回答1: I found if i use: MapViewController *mapView =

Storyboards Orientation Support in Xcode 4.5 and iOS 6.x ?

阅读更多关于 Storyboards Orientation Support in Xcode 4.5 and iOS 6.x ?

问题 I've created two storyboards both identical except one contains portrait views and one contains landscape views. I don't want to use autoresize masks because the layout of some of the views changes completely between portrait and landscape. I've manually moved controls on the view in code in the past but I was after an easier way this time :) The closest solution I've found was from 'benyboariu' - Storyboards orientation support for xCode 4.2? Here's the code I'm using which works fine on iOS

Sliding-In UIView From Bottom

阅读更多关于 Sliding-In UIView From Bottom

问题 I am trying to build a custom-looking action sheet. I thought the easiest way would be creating a view as a subview and assign constraint of subview's top to superview's bottom. And at the same time assigning a cover view with some opacity. Thus, I could have different versions of subview and I can initialise the necessary one and slide it. I couldn't find anything useful for Swift, so, using this obj-c answer, I tried to convert it to Swift. I achieved the opaque background with this however

iOS: Storyboard Segue

阅读更多关于 iOS: Storyboard Segue

问题 Currently I am working for an IPad application which shows a Slideshow on the first scene - realized with a paged UIScrollView. When I click on one page in the slideshow I want to push a new VC (to a new scene, which should present multiple thumbnails... a kind of detail layer if you want so). How can I do this via segue? Currently I simply pulled out a new VC and connected the SlideshowVC with the the next VC in the scene - but nothing happens. I wrapped my head around a couple of tutorials
