iOS8 Size-Classes and Popover Views

由 梦想的初衷 提交于 2020-01-15 07:10:29
问题 I had an issue with Popover on an iPad app I was working on recently...going to just post it here as I think it may help others. I'm using Xcode 6 and iOS 8 and Size Classes and the Popover View was built in a Storyboard. As my iPad App is in Regular/Regular Size Class all the time I built the Popover view in R/R too. No matter what I did with Constraints though, the popover just never looked right, it was a mess. So what was wrong?? 回答1: After some time the penny dropped to check the Any/Any

iOS autolayout - gap between image and top of the screen, despite constraints set

由 試著忘記壹切 提交于 2020-01-15 06:35:26
问题 I have an image that i would like to place in the top part of the screen. I've set its mode to aspect fit, because i want to preserve original ratio. I've also set left, top and right constraints to 0: Despite the fact that the top constraint is set to 0, there is a lot of empty space between the image and top of the screen which is definitely not what i want: Only when i set top constraint to about "-100" i get something similar to what i would like to achieve: Could you please explain me

How to create a segue from the disclosure indicator on a table view to another viewController?

问题 Is it possible to do that? It appears impossible to drag from the disclosure indicator on a tableViewCell prototype to a viewController to create a segue. How can I do that? 回答1: control + click on disclosure indicator connect to viewController you will get a menu like this select the accessory action 来源： https://stackoverflow.com/questions/26011945/how-to-create-a-segue-from-the-disclosure-indicator-on-a-table-view-to-another-v

10、Windows10 上，在窗口左侧向右滑动打开 SplitView 的 Pane面板

由 血红的双手。 提交于 2020-01-14 23:12:33
　　昨天想在 uwp 上实现，在 SplitView 控件的左侧，通过手指滑动打开 SplitView 的 Pane 面板， 而不仅仅是通过 “汉堡按钮” 点击打开。 　　在 stackoverflow 看到 一个帖子 ， 有讨论一个方案，然后看了一下里面的一个 github 工程，实现了 SwipeableSplitView（ 工程连接 ）， 不过下载代码分析了一下，代码量太大，通过继承 SplitView 控件，添加很多 xaml 和 C# 代码，有点复杂了。于是想了一个简单的方式，直接控制 SplitView 中 Template 的 CompositeTransform 和 VisualTransition 属性就可以了，几十行 C# 代码就能搞定。 1、运行效果 （VS2015 创建的 win10 UWP 工程） 　　1）在 phone上： 　　2）在 win10 pc 上： 2、分析 SplitView 控件的模板（只用来分析，并不使用） 　　1）在空白页面中，添加一个 SplitView，在文档大纲中，右键单击 SplitView 控件，选择编辑副本： 　　　　 　　2）在生成的代码中，可以看到，当前 SplitView 控件的组成部分： 　　这里重点使用 PaneRoot 中的 PaneTransform 属性，和 视觉状态属性中的 VisualTransition

UITableViewCell not equal to null

问题 I'm having trouble with the following code below, which basically is instantiating an extend uitableviewcell from a storyboard. The problem I'm having is that it seems leftMenuCell is never equal to null, and thus never enters the initiating block. What am I doing wrong? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"LeftMenuCell"; MenuCell *leftMenuCell = [tableView dequeueReusableCellWithIdentifier

问题 I've created a custom table view cell in my iPhone app through the following steps. In my storyboard, I created a sample cell, dragged in a UILabel and a UIImageView . Added new files, which I made a subclass of UITableViewCell . In Interface Builder, I selected my cell and I assigned its class as the class I just created in step 2. In the code for my custom table view cell, I created two IBOutlet properties and connected them to my UILabel and UIImageView in the storyboard. My custom table
