The practice of recognizing double-click events in iOS: Create the UITapGestureRecognizer object, set the value of numberoftapsrequired to 2, UITapGestureRecognizer *doubletaprecognizer = [[UITapGestureRecognizer alloc] initwithtarget:self Action: @selector (Doubletap:)]; 2 ; [Self addgesturerecognizer:doubletaprecognizer]; Action function -(void) Doubletap: (Uigesturerecognizer *) gr {

one, Click and tap ComparisonBoth will be triggered when clicked, but on the mobile web side, Click will have 200~300 ms, so tap instead of click.Singletap and Doubletap represent single clicks and double clicks, respectively.second, the point of tap processingWhen using the tap of the Zepto framework to move a click e

Document directory Introduction to Tap Features Conclusion Introduction to Tap Tap (www.tap.cn) is a new free self-help website creation service platform. Easy-to-use, professional, and efficient Tap allows you to easily get rid of the limitations of Technology on creativity in the website creation process. W

The difference between tap and click is triggered automatically when clicked, but on the web side of the phone, click will have 200~300 Ms. The delay comes from judging double-click and long-pressing, because only the default wait time ends to determine that no subsequent action occurs before the click event is triggered. So touch events react faster and experience better.Singletap and Doubletap represent single clicks and double clicks, respectively.

First, click and tap ComparisonClick and tap will be the starting point of the event, but on the mobile phone web side, click will have 200-300ms delay, so the general use of tap ( tap ) instead of click for clicking Events. Singletap and DOUBLETAP respectively represent clicks and double clicks.Second, the use of

Obviously, after the advent of the Windows 8 system, the major PC manufacturers have mixed design products as a new profit growth point, and the Haswell processor to bring the long-term endurance of this or tablet, or notebook products have more practical value. Among them, Sony once focused on the slide-in tablet/notebook two-in-one product, but its complex design has not been a consumer pro-gaze, so the company has finally returned to the more traditional win 8 tablet area, the introduction of

1. What the Touch Library implements and introduces the backgroundThe click Event has a 300ms latency on the mobile side, and because of the need for 长按 双触击 rich interaction, we usually introduce libraries like zepto. The Zepto in touch Library implements ‘swipe‘, ‘swipeLeft‘, ‘swipeRight‘, ‘swipeUp‘, ‘swipeDown‘, ‘doubleTap‘, ‘tap‘, ‘singleTap‘, ‘longTap‘ some of these features.2, Touch Library implementation‘swipe‘, ‘swipeLeft‘, ‘swipeRight‘, ‘swi

Along with the custom instructions and plugin documentation, a V-TAP directive was implemented last night, and the dry goods were thrown out. Introduction to instructions and Plug-insCustom directives and plug-in

In the computer network, Tun and tap are virtual network devices in the operating system kernel. Different from the common hardware network card implementation of the device, these virtual network devices are all software implementation, and running on the operating system of the software to provide the hardware and network equipment exactly the same function.TAP equates to an Ethernet device that operates on a second layer of packets such as an Ether

In short, SystemTap allows-dig out a bunch of details about your running system relatively easily. It takes scripts, converts them to C, builds a kernel module, and then runs the code within your script.Hold it:the steps below is de

iOS development UI Chapter-gesture recognizer (TAP)first, the practice of listening to touch eventsIf you want to listen to a touch event on a view, the previous practice is to customize a view first, and then implement the touches method of the view to implement the specific processing code inside the methodThere are a few obvious drawbacks to monitoring the view touch event through the touches method(1) Custom view required(2) Because the touch even

Implementation of the tap event in zepto. js to prevent bubbling This article mainly introduces the implementation method of the tap event in zepto. js to prevent bubbling. The example analyzes the solution to the click latency caused by bubbling. For more information, see The example in this article describes how the tap event in zepto. js blocks bubbles. Shar

There is a penetration problem when using tap on the mobile sideA: Click comparison with TapClick and tap will trigger a hit event, but on the mobile web, click will have a 200-300ms delay, so tap instead of click is generally used for clicking events.
