由 这一生的挚爱 提交于 2020-02-02 10:21:01
问题 Does anyone know why this does not work? With this, just one tab bar load the view, the other make black screen. I Have tried without Navigation Controller, and Tab bar is correct and the other doesn't show the tabBar item in running mode. 回答1: My answer for this problem if anyone is interested. Add two views that will launch the view we are interested. Same file for this 2 views : @interface PushToAgenceViewController : UIViewController @end -(void) viewWillAppear:(BOOL)animated { [self

Universal layout vs different iphone/ipad storyboards

由 随声附和 提交于 2020-01-31 03:42:04
问题 Is it okay to use different storyboards for different screensizes? I just can't make my png and icons images work for one storyboard as universal, it's a pain! What about universal iPhone and universal for iPad? What's the best way? Thanks 回答1: You can also use one storyboard and set layout and font according to your requirements. 1) To set up layout properly for both iPhone and iPad, you need to use Aspect Ratio.

WPF学习（12）动画

由 一曲冷凌霜 提交于 2020-01-30 19:20:51
本篇来学习WPF的动画。什么是动画？动画就是一系列帧。在WPF中，动画就是在一段时间内修改依赖属性值的行为，它是基于时间线Timeline的。有人会说，要动画干嘛，华而不实，而且添加了额外的资源消耗而影响性能。尽管如此，适当的使用动画却可以使你的程序富有更好的表现力和交互性。更加可喜的是，WPF提供了丰富的动画支持，大部分的动画都可以直接通过XAML来呈现而不用去写繁琐的cs代码。在System.Windows.Media.Animation命名空间中，我们发现了许多的类，大体可归类为这么三种：基于线性内插算法动画（简单动画）、基于KeyFrame动画和基于路径动画。下面来分别介绍这三种动画： 首先以图来说明类的继承层次： 这张粗糙的图只是以Double类型的动画为例，因为它是比较全的，全面提到的三种动画类它都具备。支持KeyFrame的类型最多，其次是线性内插，最后是路径，只有三种，除了Double外，还有Matrix和Point。 1.基于线性内插算法动画（简单动画） 基于线性内插动画是在一个开始值到一个结束值之间以逐步增加的方式来改变属性值。有这么几个重要的属性： From:开始值，当忽略该属性时，动画默认从其使用者属性值开始，所以其使用者属性在执行动画前要被赋值 To:结束值，当忽略该属性时，动画默认从其使用者属性值结束，所以其使用者属性在执行动画前要被赋值 By:递增值

Xcode 4.5 Storyboard 'Exit'

由 混江龙づ霸主 提交于 2020-01-27 08:53:26
问题 I have just installed Xcode 4.5 for iOS6 support, and I have seen a new icon called 'Exit' in my Storyboard, listed under my view controllers along with 'First Responder' etc. A little green icon labeled 'Exit'. I can find anything on it nor work out how it can be used. Anyone know anything about it, how it works, what its for? 回答1: This is called an " Unwind Segue ". Unfortunately there's no documentation for this so far except a brief mention on XCode 4.5 new features list that states:

iOS开发之抽屉效果实现

由 ☆樱花仙子☆ 提交于 2020-01-27 04:55:25
　　说道抽屉效果在iOS中比较有名的第三方类库就是PPRevealSideViewController。一说到第三方类库就自然而然的想到我们的CocoaPods，今天的博客中用CocoaPods引入PPRevealSideViewController,然后在我们的工程中以代码结合storyboard来做出抽屉效果。 　　一.在工程中用CocoaPods引入第三方插件PPRevealSideViewController. 　　　　(1).在终端中搜索PPRevealSideViewController的版本 　　 　　　　(2).在Podfile中添加相应的版本库 　　　　(3).之后保存一下Podfile文件，然后执行pod install即可 　　二、为我们的工程添加pch文件 　　　　因为用的是XCode6, 上面默认是没有pch文件的，如果我们想使用pch文件，需要手动添加，添加步骤如下 　　　　1.在XCode6中是么有pch文件的，如下图 　　　　2.创建pch文件 　　　　 　　　　3.配置pch文件 　　　　　　(1)、找工程的Targets->Build Settings->Apple LLVM 6.0 - Language 　 　　　　　　(2)在Prefix Header下面的Debug和Release下添加$(SRCROOT)/工程名/pch文件，入下图

How to check the storyboard whether this is begin or not?

由 ▼魔方 西西 提交于 2020-01-24 17:00:06
问题 I need to know whether the Storyboard is begun or not. If it is begun, I need to stop, otherwise I no need to stop. Both begin and stop will be done in code behind. Currently I've done this: if (parameter != null && parameter is System.Windows.Media.Animation.Storyboard) { if (!(bool)value) { (parameter as System.Windows.Media.Animation.Storyboard).Begin(); return Visibility.Visible; } else { (parameter as System.Windows.Media.Animation.Storyboard).Stop(); return Visibility.Collapsed; } } I
