First of all explain why you should learn gesture recognition?If you want to listen to a uiview above the touch event, the previous practice is: Customize a UIView, implement UIView touches method, in the method to achieve specific functionsThere are a few obvious drawbacks to monitoring UIView's touch events through touches:1. You must customize the UIView,2. Because the touch event is monitored in the touches method inside the view, it is not possible to allow other external objects to listen

Cancelstouchesinview;Whether to delay sending touch events to the touch controlThe default is no, in which case when a touch occurs, the gesture recognizer snaps to the touch and then sends the touch to the control, each responding. If set to Yes, the gesture recognizer is in the process of recognition (note that the recognition process),The touch is not sent to the touch control, that is, the control does not have any touch events. Touch events are sent to the touch control only after the reco

1. Introduction:The UIKITK Framework provides a series of class (classes) to establish and manage the user interface (UI) interfaces, application objects, event controls, drawing models, Windows, views, and interfaces for controlling the touch screen of iphone OS applications. (PS1: An API library that can be considered a manipulation interface.) (The Ps2:uikit framework is used on the iOS platform that corresponds to the application Kit on Mac OS X,

First, the Cisco router to introduce the memory A router is similar to a computer in that it also has memory, operating system, configuration, and user interface, and the operating system in Cisco routers is calledInternet Operating System (Internetwork operating system) or iOS. The following is mainly about the storage of routers. ROM: Read-only memory contains a copy of the iOS being used by the router;

How do I set up a custom back button picture?If our return button does not need to display text, or if the text displayed is fixed and can be done in the picture, then I recommend to customize the return button by setting the new backindicatorimage introduced in

Ideas The previous article only talked about unity and the integration of the iOS project, and did not talk about the handover of iOS and Unity interface, here to talk about ideas, unity export of the IOS project inside the structure is roughly the same, there is a window,window on a unityview, But there is no controller, there is no root controller, although in

LLDB is the abbreviation of low level debugger, LLDB is often used in the debugging of iOS development, LLDB is the Xcode built-in dynamic debugging tool. Use LLDB to debug your application dynamically, and if you don't do additional processing because Debugserver lacks task_for_pid permissions, you can only use LLDB to debug your own app. In this blog, you will use LLDB to debug apps downloaded from the App Store, and combine hopper to analyze the st

Event Handling Guide for iOS Reading Notes (1) Gesture Recognition Gesture Recognizers Gesture Recognition Overview: 1. The application can get events from the user's touch VIew. 2. Applications can get events from users' mobile devices. 3. Applications can obtain remote control events from users' multimedia operations (such as volume control from headphones) Gesture Recognizers Gesture Recognition Gesture Recognition is a process from a low-level

I. Gesture recognizersGesture recognizers is an object introduced in iOS3.2 that can be used to identify gestures and simplify custom view event handling. The base class of Gesture recognizers is Uigesturerecognizer, an abstract base class that defines the programming interface for implementing the underlying gesture recognition behavior. 6 specific Gesture recognition classes are provided in the Uikit framework to identify common
