I have to fill a TableView with lots of items (20.000 items frol sqlite) but I know that I will give it overload Is there any way to load only the required data during scoring? For example, if I scroll more than 100 then 100 tables should be displayed, should I load 200 table or just load 101 101 items?
-text "itemprop =" text ">
I will fill a TableView with many items (20.000 items frol sqlite) but I know that I will overload it while scrolling only loads the required data What is the way to do that?
UITableView is specially designed to load only cells that are visible to you through the data source of the table Available in the table Do not "fill the table" to create the data. In the form of table scroll, it asks its data source for extra cells, and it re-uses cells that are no longer visible. This memory Reduces usage and maximizes speed to implement the necessary table view data source in your view controller (or some other object) and implement delegation methods Area than you bring cell content for each element in it something to do not need to.
embedded sqlite DB?
Of course, you can do this simply apply your -tableView: cellForRowAtIndexPath: method to create the appropriate SQLite query for the requested cell.

I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...
