[IOS] Swift beginner's Manual: optional type (Optionals) A few weeks ago (Translator's note: the original article was published in June 24), Apple released a brand new programming language: Swift.

Often we will display many items with TableView, sometimes need to display pictures, but once from the server to take all the pictures to the user to waste traffic, the server is also a burden. It is best to load on demand, that is, when the user wants to browse for the item and then loads its picture.-(void) TableView: (UITableView *) TableView Willdisplaycell:

Check more options at the bottom of the table and click View More to view the remaining items of the resolution.Data. BasicallyDataAdd only 10 entries in the source. When you click the last cell, add moreDataToDataSource. For example: The data source is an array: NSMutableA

First, refresh the listWhen a row of TableView data is modified, the data needs to be updated. There are two methods of refreshing:(1) Refresh the entire list, that is, [self. TableView reloaddata]; (2) Only the changed line is refreshed. Of course, this method is more efficient than the first method.Specific code: nsindexpath *refreshcell = [Nsindexpath indexpathforrow : 3 insection:0];[ self.

The estimated height of tableview in iOS after iOS7, TableView has the concept of estimating height and related properties and methods; What is its role and usage scenario? After the TableView loading data rendering, take into account the length of the scrollbar problem, so you want to all the cell height at once to complete the calculation, so as to determi

Recently in the project. To do this, add an input box to the cell above the TableView. Allow user input.1. My first choice is to set the contents of the TableView to the top of the keyboard when the Uitextview is notified and the keyboard appears. But I do not know why, my keyboard appeared, but TableView did not appear. But when I type,

IOS sets a blank interval between cells in TableView. 1. Set the number of sections, that is, how many cells do you have? - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 3; // in your case, there are 3 cells} 2. Return a cell for each section - (NSInteger)tableView:(UITableView *)tableView

IOS delays loading pictures in Cell in TableView In TableView, delayed loading of images is the content to be introduced in this article. We often use tableView to display many entries, and sometimes we need to display images. However, retrieving all images from the server at one time wastes traffic on the user, which is also a burden on the server. It is best to

Objective When we create a tableview, carefully you have not found UITableViewCell left there will be blank. And we have this need in development: a complete split line (remove annoying whitespace, the width of the split line = screen width). So I'm going to talk about how to get rid of the blank section and show the complete split line. Here I offer two ways: The first method, and also our most common method, is what we use when we customize the

Check storyboard here.AfterThis cell needs a uilabel to show the Chinese name of the city (this uilabel is just to show what to do when customizing a cell in storyboard, in general there is a textlabel in the cell that can display text). Then add a Label pr
