Angularjs localStorage存储cordova应用程序中的设置

LocalStorage不是永久存储,而WebSQL似乎对存储设置有点过分.

您不必过多参与Objective-C并且有很好的Phonegap / Cordova插件指南：

http://docs.phonegap.com/en/3.3.0/guide_hybrid_plugins_index.md.html#Plugin%20Development%20Guide

我使用此代码存储“FirstRun”变量来检查应用程序是否是新安装.插件检查应用程序之前是否已运行,并返回1或0,将其解析为整数并计算为true / false.

您可以更新此代码并向“AppChecks”类添加更多方法.我把所有简单的检查和设置存储放在这个类中.

AppChecks.h

#import <Cordova/CDVPlugin.h>

@interface AppChecks : CDVPlugin

- (void) checkFirstRun:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options;

@end

AppChecks.m

#import "AppChecks.h"
#import <Cordova/CDVPluginResult.h>

@implementation AppChecks

- (void) checkFirstRun:(NSMutableArray *)arguments withDict:(NSMutableDictionary *)options {
NSString* callbackId = [arguments objectAtIndex:0];

CDVPluginResult* pluginResult = nil;
NSString* javaScript = nil;

@try {

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSString *isFirstRun = @"1";

    if (![defaults objectForKey:@"firstRun"]) {
        [defaults setObject:[NSDate date] forKey:@"firstRun"];
    } else {
        isFirstRun = @"0";
    }

    pluginResult = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString:isFirstRun];
    javaScript = [pluginResult toSuccessCallbackString:callbackId];
} @catch (NSException* exception) {
    // could not get locale
    pluginResult = [CDVPluginResult resultWithStatus:CDVCommandStatus_JSON_EXCEPTION messageAsString:[exception reason]];
    javaScript = [pluginResult toErrorCallbackString:callbackId];
}
[self writeJavascript:javaScript];
}
@end

在我的Javascript代码中使用：

cordova.exec(
    function( isFirstRun ) {
        isFirstRun = parseInt( isFirstRun );
        if( isFirstRun ) {
          // do stuff for first run
        }
    },function(err) {
        // handle error from plugin
    },"AppChecks","checkFirstRun",[]
);
