【问题描述】：

如何执行以下操作

[self.commandDelegate sendPluginResult:[CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString:**response**] callbackId:command.callbackId ];

然后得到结果为

$.when(phonegap.function(params)).then(function (**resp**) 
//Get the response here 

);

【参考方案1】：

您需要使用 cordova.exec API 来使其工作

确保您已经在 config.xml 中定义了插件

<feature name="CustomPlugin">
      <param name="ios-package" value="CustomPlugin" />
</feature>

使用Objective-C代码实现插件

CustomPlugin.h

#import <Foundation/Foundation.h>
#import <Cordova/CDV.h>

@interface CustomPlugin : CDVPlugin

- (void)sayHello:(CDVInvokedUrlCommand*)command;

@end

CustomPlugin.m

#import "CustomPlugin.h"

    @implementation CustomPlugin

    - (void)sayHello:(CDVInvokedUrlCommand*)command

        NSString *responseString =
            [NSString stringWithFormat:@"Hello World, %@", [command.arguments objectAtIndex:0]];

        CDVPluginResult *pluginResult =
            [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString:responseString];

        [self.commandDelegate sendPluginResult:pluginResult callbackId:command.callbackId];
    

    @end

从 javascript 调用插件

function initial()
    var name = $("#NameInput").val();
    cordova.exec(sayHelloSuccess, sayHelloFailure, "CustomPlugin", "sayHello", [name]);


function sayHelloSuccess(data)
    alert("OK: " + data);


function sayHelloFailure(data)
    alert("FAIL: " + data);
