只谈情不闲聊 提交于 2019-12-03 08:07:24
I have to create Grid view like Appstore iOS app. I want to do this with UICollectionView paging. I have also implemented the code but not able to scroll like that. What I want to do is there will one image in Center and at both sides(left and right), it should show some portion of previous and next image. I have set Frame for UICollectionView is 320*320. cell size is 290*320.(cell min spacing is 10) 1 Below are two links which depicts my requirement. Thanks in advance. (This is what I want) 2 Deepak Have you tried setting the scroll direction of your UICollectionViewFlowLayout to horizontal?

UIScrollView - (bounces = NO) seems to override (pagingEnabled = YES)

跟風遠走 提交于 2019-12-03 07:59:45
I have a UIScrollView with paging in it (so the typical model with a UIPageControl and dragging/flicking left and right between pages), and I've got that working fine. The weird thing is that when I wanted to get rid of bouncing (so that you can't see black behind the UI on the left and right sides), suddenly paging no longer works. In other words, when: scrollView.pagingEnabled = YES; scrollView.bounces = YES; Everything works fine, except I don't like the bouncing at page(0) and page(length-1). But when I do this: scrollView.pagingEnabled = YES; scrollView.bounces = NO; It stops snapping

Equivalent of FOUND_ROWS() function in Postgresql

霸气de小男生 提交于 2019-12-03 07:58:49
问题 I am doing some paging in my application, returning 20 rows from the database at a time using PostgreSQL's standard OFFSET and LIMIT keywords. For instance, to get page 1 page: SELECT stuff FROM table WHERE condition ORDER BY stuff OFFSET 0 LIMIT 20 It is a requirement of the application that we also show to the user the total number of records. So, obviously, I can get the total by issuing a separate query: SELECT COUNT(*) FROM table WHERE condition But if there are a large number of rows

Facebook graph API loop through paging

廉价感情. 提交于 2019-12-03 07:48:09
问题 So I was working with this script to loop through the events from a given page. Suddenly I find it doesn't work anymore :( I have a feeling it could be a bug, because if you pick any page, view events with an access_token, you can't get any data back for the "next" paginated URL. e.g. try https://graph.facebook.com/evenightclub/events in apigee.com Any ideas? ($fid is the page object id) try { $facebook = new Facebook(array( 'appId' => '<removed>', 'secret' => '<removed>', )); $access_token =

Is there a paging solution for ASP.NET MVC that does paging in the database?

倾然丶 夕夏残阳落幕 提交于 2019-12-03 07:24:16
问题 Most of the ASP.NET MVC paging solutions I have found by googling look like they get all rows from a database table in the form of a IEnumerable collection, perform some paging conversion on the IEnumerable collection, and then return the results to the view. I want to be able to page on the DB side but still have some paging class to do the page number calculations and HTML generation. Is there a solution out there that does this? Or are the ones i've been looking at do this, but i'm not

When to do or not do INVLPG, MOV to CR3 to minimize TLB flushing

谁都会走 提交于 2019-12-03 06:48:15
问题 Prologue I am an operating system hobbyist, and my kernel runs on 80486+, and already supports virtual memory. Starting from 80386, the x86 processor family by Intel and various clones thereof has supported virtual memory with paging. It is well known that when the PG bit in CR0 is set, the processor uses virtual address translation. Then, the CR3 register points to the top-level page directory, that is the root for 2-4 levels of page table structures that map the virtual addresses to

What is the Equivalent syntax of mysql “ LIMIT ” clause in SQL Server

人走茶凉 提交于 2019-12-03 06:18:20
What is the Equivalent syntax of MySQL " LIMIT " clause in SQL Server . I would like to use it for doing paging of my results. (want to show records5 to 10 ) The closest thing is TOP: Select top 5 * from tablename You can get a range ( rows 5 - 10) SELECT * FROM ( SELECT TOP n * FROM ( SELECT TOP z columns -- (z=n+skip) FROM tablename ORDER BY key ASC ) ) The closest to it is SELECT TOP X but it is only equivalent to LIMIT X . For LIMIT X, Y , there is no direct MS-SQL equivalent (as far as I know). Christian's solution is a good one though. MSSQL2005 (onwards) has the ROW_NUMBER syntax which

AngularJS Paging orderBy only affects displayed page

半城伤御伤魂 提交于 2019-12-03 06:05:54
Can anyone point me in the right direction to figure out a way to fix the way paging and orderBy work together in Angular? Currently, I can orderBy and page the results of the data[], but the orderBy filter only affects the each page individually. For example, if I sort in reverse order by ID, page 1 will list 10-1, and page 2 will list 15-11, as opposed to starting with 15 and going to 1 by the end of the second page. I have a basic fiddle here http://jsfiddle.net/ZbMsR/ Here is my controller: function MyCtrl($scope) { $scope.currentPage = 0; $scope.pageSize = 10; $scope.orderBy = "-appId";

Why using hierarchical page tables?

送分小仙女□ 提交于 2019-12-03 05:01:10
问题 I'm learning the Linux kernel and reading the book The Linux Kernel . Can anybody explain why can't we just use the table which maps directly between logical and physical memory instead of the tree-like multilevel structure? Added: The total number of entries needed is fixed, so I assume that it's more space wasting to store a complicated structure than a simple one. 回答1: You will appreciate the space optimization of multi-level page tables when we go into the 64-bit address space. Assume you

ListView with DataPager not working

感情迁移 提交于 2019-12-03 04:55:00
From everything I've read, it seemed that adding paging to a ListView control should be dead simple, but it's not working for me. After adding the ListView and DataPager controls to the form and wiring them together, I'm getting very odd behavior. The DataPager correctly limits the ListView's page size, but clicking the paging buttons doesn't affect the ListView at all. The paging buttons seem to think they are doing they're job, as the last button is disabled when you go to the last page, etc., but the ListView never changes. Also, it takes two clicks on the DataPager to get it to do anything
