Events in iOS A variety of events occur during the user's use of the app Events in iOS can be divided into 3 major types--Touch Event ———— Accelerometer Event ———— Remote control event- Responder Object Not all objects in iOS can handle events, only objects that inherit Uiresponder can receive and handle events. We call it "responder object." UIApplication, Uiviewcontroller, and UIView inherit from Uiresponder, so they a

is 45, we cannot determine whether the phone is tilted up or down. At this time, the acceleration sensor will be used. It can determine the positive and negative angle, positive value indicates from the horizontal line up, copy indicates from the horizontal line down. In short, everything we need can be obtained from the accelerometer. So far, we have introduced all the tools required to build your own Augmented Reality Technology engine. You still n

For devices with gyroscopes, you can also obtain data on the original gyroscope data and the direction and rotational speed of the processed reaction device. You can use both

This type of“Diving Board"motion alters the movement of the current in the structure, thus indicating the displacement change associated with gravity. another kind of accelerometer technology for the thermal convection technology, has several obvious advantages. it has no moving parts, but a“Hot Gas Regiment"the displacement to perceive the motion changes.

If the final hit-test does not find the first responder, or if the first responder does not handle the event, the event will go up backwards along the responder chain, and the event will be discarded if neither the UIWindow instance nor the UIApplication instance can handle the event;2.

compilationNow plug in your Android phone and run the first Cordova program. Choose Debugging equipment on the menu, recommended to debug with the real machine, I once used the VS2015 Android simulator, the speed is very fast, but the network was ruined. For this simple Cordova program, it is also possible to use ripple. Ripple is a plugin that runs in Chrome, and also provides some features such as GPS, back keys, and other emulators.If it is the first time to compile the Cordova project, will

Accelerometers are the basis for the entire iOS screen rotation, depending on the accelerometer. The device is capable of inferring the current device orientation, and the iOS system defines the following seven device orientations:typedef ns_enum (Nsinteger, uideviceorientation) {Uideviceorientationunknown,Uideviceorientationportrait,//Device oriented vertically, home button on the bottomUideviceorientationportraitupsidedown,//Device oriented vertical

This article illustrates how Android uses the sensor sensor to get the direction of a user's movement. Share to everyone for your reference, specific as follows: Today continue to share a second important sensor, in fact, to get the direction of the things should be very simple, in the previous article to see that there is a type_orientation keyword, you can directly get the direction of the device, but the latest version of the SDK plus such a sentence "Type_ Orientation This constant is depre

Gesture operation can be said to be a smart phone charm, the first two sections to explain the two interesting gestures, put them in the game, greatly enhance the game's playful and interesting. This section will continue to introduce another magical thing about smartphones: sensors. first, what is the sensor The so-called sensor is to be able to detect such as light, heat, temperature, gravity, direction and so on devices. Ii. What are the sensors that Android offers 1. Acceleration sensor

Events in iOS fall into three categories: touch events, accelerometer events, and remote control events. Only objects that inherit Uiresponder can receive and process events, called Responder objects. UIApplication, Uiviewcontroller and UIView all inherit from Uiresponder. Uiresponder internally provided methods to handle events: Touch events: Touchesbegan, touchesmoved, touchesended, touchescancelled Accelerome
