Tableview:didselectrowatindexpath method code as follows: -(void) TableView:( UITableView *) TableView Didselectrowatindexpath:( Nsindexpath *) Indexpath { if (indexpath.section = = 0) [Self.nametextfield Becomefirstresponder];} That is, when the user touches the first cell, we activate the TextField focus (there is only one cell in this section, so we just need to check the index of the section). This will automatically eject the soft keyboard. This is only trivial wo

As an iOS programmer, what are the core 60% competencies?How many core skills does a qualified iOS programmer need to master? How big is the gap between you and a professional development engineer? Do you have the ability to develop an iOS app that is functionally complete and efficient? Take a look at the following

If you have not read the previous article, you can move to see: iOS 3D Engine SceneKit Development (4) – Some questions about rotation (1)We used cabasicanimation to simulate the sun-Earth-Moon celestial movement. The movement of the Moon around the sun and the moon around the earth can be seen as a circular movement around the other point. (Of course, there is elliptical motion, there is apogee, perigee, here we treat as a circular motion)A point aro

Run the program, swipe the gesture on a line, and see what happens. The Delete button appears on the cell, but it also obscures the level picture. In fact, because the delete button occupies some c

certain events or to define certain parameters. Cocoa and iOS rely heavily on the concept of proxies. such as the UITableView class, this class does not know what the title of the table is, how many chunks to include or how many rows to fill, and what the contents of the table are. So, the proxy defines a uitableviewdatasource protocol, and if it needs informati

For beginners who want to get into the line, the main focus is on code learning, with storyboard as an aid to better understand view controllers, views, controls, and various jumps. As to
