                    var settings = app.currentUserNotificationSettings();  
                    enabledTypes = settings.plusGetAttribute("types");  
                    console.log("enabledTypes1:" + enabledTypes);  
                    if (enabledTypes == 0) {

判断蓝牙是否开启

判断蓝牙权限是否开启无法用native.js来写，可以用蓝牙模块的API， getBluetoothAdapterState（获取本机蓝牙适配器状态），onBluetoothAdapterStateChange（监听蓝牙适配器状态变化事件）来判断。

提示用户开启权限

跳转到应用的权限页面，下面写了一个提示框让用户去选择

                                      plus.nativeUI.confirm("XX权限没有开启，是否去开启？", function(e) {  
                        if (e.index == 0) {  
                            var UIApplication = plus.ios.import("UIApplication");  
                            var application2 = UIApplication.sharedApplication();  
                            var NSURL2 = plus.ios.import("NSURL");                        
                            var setting2 = NSURL2.URLWithString("app-settings:");  
                            application2.openURL(setting2);  

                            plus.ios.deleteObject(setting2);  
                            plus.ios.deleteObject(NSURL2);  
                            plus.ios.deleteObject(application2);  
                        }  
                    }, {  
                        "buttons": ["Yes", "No"],  
                        "verticalAlign": "center"  
                    });
