When I first started learning Android, I felt that Google's documents were not good, and when we studied gestures, I felt that Google's documents were too poor. A lot of constants, properties, and methods don't even have a description. There is no description, but there are so many gestures in ongesturelistener, it does not have a description, who can understand onlongpress and onshowpress before they try.I

Ios gestures are an indispensable part of ios development. However, you do not know the mechanism of ios gestures and events. So today I would like to share with you the corresponding mechanism of ios events. First, ios event transmission relies on the "event chain". When an object passed to a link of the chain processes the event, the event will be stopped. So the event chain is a thing of God and horse?

Simple methods and gestures for creating arrays in iOS In fact, outsourcing is also quite good. Although tired, the daily knowledge has been expanded a lot. The following are the gains of today. ① Method of initializing array-1 dictionary @ [] Initializing an unchangeable Array @ {} Initialize an unchangeable dictionary ② Use of gestures In iOS, four methods are used before processing

The Touch API consists of two parts: the management of the gesture API of the touch input, and the physical engine API that controls how the display area reacts to the user's touch. Touch functions, messages, and struct are shared with the mouse, because the application processes a handwritten event like a left-click mouse. For mor
