手电筒的打开与关闭,话不多说直接上代码
打开

				try {
					var os = plus.os.name;
					if ('iOS' == os) {
						var device = plus.ios.invoke('AVCaptureDevice', 'defaultDeviceWithMediaType:', 'vide');
						plus.ios.invoke(device, 'lockForConfiguration:', null);
						plus.ios.invoke(device, 'setTorchMode:', 1);
						plus.ios.invoke(device, 'setFlashMode:', 1);
						plus.ios.invoke(device, 'unlockForConfiguration');
					} else {
						var main = plus.android.runtimeMainActivity();
						var camera = main.getSystemService('camera');
						var ids = plus.android.invoke(camera, 'getCameraIdList');
						for (var i = 0; i < ids.length; i++) {
							var c = plus.android.invoke(camera, 'getCameraCharacteristics', ids[i]);
							var available = plus.android.invoke(c, 'get', plus.android.getAttribute(c,
								'FLASH_INFO_AVAILABLE'));
							var facing = plus.android.invoke(c, 'get', plus.android.getAttribute(c, 'LENS_FACING'));
							if (null != available && available && null != facing && 1 == facing) {

						}
					}
				} catch (e) {
