Detailed description of batch display data in iPhone tableview

Batch display of iPhone tableview data is the content to be introduced in this article, mainly about data display. The iPhone screen size is limited. If you need to display a large amount of data, you can first put the data into a table, first display 10, there are more options at the bottom of the table, click to view more and view the remaining parsed data. Basically, there are only 10 entries in the data source. When you click the last cell, add more data to the data source. for example, the data source is an array: nsmutablearray * items; this method of viewcontroller returns the number of data records: + 1 is used to display the cell-(nsinteger) for "loading more) tableview :( uitableview *) tableview numberofrowsinsection :( nsinteger) Section {int COUNT = [items count]; return count + 1;} This method customizes the display of cells, especially the cell "load more":-(uitableviewcell *) tableview :( uitableview *) tableview cellforrowatindexpath :( nsindexpath *) indexpath {If ([indexpath row] = ([items count]) {// create loadmorecell return loadmorecell;} // create your data Cell Return cell ;} you also need to process the selection event of the cell "load more" and trigger a method to load more data to the list-(void) tableview :( uitableview *) tableview didselectrowatindexpath :( nsindexpath *) indexpath {If (indexpath. row = [items count]) {[loadmorecell setdisplaytext: @ "loading more...

I hope this article will help you!
