问题 I want to develop ePub & PDF reader for iOS devices. For PDF reader , I can display PDF in Web View. So I don't have any problem with PDF. For ePub files, my idea is 1) Download epub files from server & extract it to Documents directory as per requirement. 2) Parse extracted files & display it. 3) Once app closed , delete extracted files from Socuments directory. Required functionality :- 1) Increase / Decrease Font size & brightness 2) Bookmark 3) Left & Right Swipe gesture OR Curl effect

问题 I'm having trouble getting expressions to render in Angular2. For instance, I have something like the example below, but the {{profile.name}} renders nothing. However it's not just when accessing something off the component instance. No matter what I put in the expression, it won't render (e.g. {{1 + 2}} ). And what's weirder, it deletes all the content of the DOM element the expression is contained in. import { Component, View } from 'angular2/core' @Component({ selector: 'my-component' })

问题 I've achieved what I'm trying to do, but I can't help but to think there is a more efficient way...allow me to illustrate. In short, the question I'm asking is if there's a way to determine when a component has finished it's initial rendering. I have a JList, which is hooked up to a DefaultListModel and getting painted by a custom renderer which extends the DefaultListCellRenderer. This intention of the JList is to "page" through a log file, populating 2500 elements every time a new page is

问题 (Note: I'm using Expo for this app) I'm attempting to render a FlatList that displays a list of printers. Here's the code: <FlatList data={printers} keyExtractor={printer => printer.id} renderItem={({ item }) => { return ( <Printer printerTitle={item.name} selected={item.selected} last={item === last(printers)} /> ); }} /> Here's the code for the <Printer /> component: const Printer = props => { const { last, printerTitle, selected } = props; return ( <View style={[styles.container, last ?

问题 I'm using React Router 4. When I render component with render parameter componentWillReceiveProps() it doesn't fire the fist time, so I need to click twice to sent props to the component. I render like this: const CartRoute = (props) => (<Cart itemsInCart = {this.state.itemsInCart} deleteItemFromCart = {this.deleteItemFromCart} {...props} />); ..... <Switch> ..... <Route path="/cart" render={CartRoute} /> </Switch> Without Router (when all components are on the same page) it works ok. Here is

Here is the bean: boolean showPage = true; public boolean getShowPage(){ return showPage; } Here is the view: <h:form> <p:commandButton value="Click" action="#{bean.hideContents()}" /> </h:form> <p:panel rendered="#{bean.showPage}"> Contents </p:panel> The panel gets hidden when I manually refresh the page, otherwise it does not. How is this caused and how can I solve it? 回答1:

问题 Hopefully have a simple question here but I cannot for the life of me seem to find the answer. Just started working with RoR but came from ASP MVC before. I am having an issue rendering partial views whose local variables are not necessarily tied to the variables of the main view. For instance, with a blog I am trying to render a sidebar that will link to the archive. def sidebar @blog_posts = Blog.all(:select => "created_at") @post_months = @blog_posts.group_by { |m| m.created_at.beginning

问题 My problem is similar to the one in this question, but the opposite. How do I specify ":layout => false" in Rails' respond_with? The controller is sort of a file converter. It responds to many formats. One format is supposed to render an html layout showing metadata. This format need the layout to be rendered, unlike most other formats. Problem is I can't convince Rails to render it. class CustomFilesController < ApplicationController respond_to :all, :only => :show def show @custom_file =
