ios - Should I use dequeReusableCellWithIdentifier? -


i know question dumb. got stuck question.

when use dequereusablecellwithidentifier, cells reused. more specific, first 'n' set of cells reused - along references

as same references reused, can't store local variables cells. need assign them everytime in cellforrowatindexpath

assume i'm using custom complex uitableviewcell. (i know should reduce complexity. still...)

some views added cell.

best example think of image slider.

so number of images in image slider differs based on datasource. need add views in cellforrowatindexpath. can't avoid it.

since same reference of cells reused, need add these views everytime cellforrowatindexpath called. think bit of heavy load.

i thought of using drawrect method, not work uitableviewautomaticdimension

if don't use dequereusablecell, have individual referenced cells, cost memory , performance.

so best solution? can use dequereusablecell , still need not rewrite content?

edit 1: mentioning dequereusablecell, did mention dequeuereusablecellwithidentifier - forindexpath. i'm sorry confusion.

edit 2: i feel, i'm not clear in question.

lets consider have array in viewcontroller. i'm configuring cell in cellforrowatindexpath dequeuereusablecellwithidentifier - forindexpath

so happens is, everytime scroll, when invisible rows become visible, cellforrowatindexpath called.

lets have image slider n imageviews. each cell, 'n' differs. i'm forced draw cell's view based on datasource.

so everytime tableview calls cellforrowatindexpath, cell configured again , again.

i want avoid improve performance.

what in case following:

  1. i use dequereusablecell:, reasons said
  2. i write cleancell method in custom uitableviewcell class in order clean has been set on cell (just make ready reuse)
  3. then in cellforrowatindexpath: configure cell desired

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
