Access control is sometimes critical for the reliability of a device node. This part of content is only modified on the open and release methods, and some check mechanisms are added. Exclusive Device The most rigid access control method is to allow a device to be opened (exclusive) by a single process at a time, which is the simplest access control for a device driver. The implementation is very simple. For specific code, see the experiment source code! Module Program link: Scullsingle.tar.gzMo

Engineering code is not particularly complex, by inheriting cordovaactivity on the first page of activity, Parse the CONFIG. ins file, do the initial setup, then embed the Cordovawebview and load the URL of the page configured in CONFIG.Cordova is just a webview shelf that gives you the ability to invoke the native API, and in the UI he doesn't care what your page looks like, nor does it give you any UI features, so the UI also relies on jquery Mobile, Sencha Touch, App Framework (Jqmoby), Kend

This study continues based on the previous project (you can also create a new project) to learn segmented control and switch. Segmented Control Switch The main difference between segmented control and switch is that segmented control can have multiple values for selection, while switch has only two values. 1) Add segmented ControlDrag a segmented control from the object library to the iPhone interfaceThen adjust the position of the segmented Control and Its width, as shown in figureOne attribute
