ios - 将自定义参数传递给 Phonegap 插件

我编写了一个 Phonegap 插件，以便将我的 Phonegap 应用程序与原生 SDK 库集成。为了将一些设备注册信息传递给本地库，我使用了一个 Objective-C 类别在 didFinishLaunchingWithOptions 之后插入我自己的处理程序，几乎与 Phonegap Push Plugin 相同。做。因此，我有以下内容:

@implementation AppDelegate (MyLib)

// Using method swizzling to plug our own init method  which allows us to
// add our own listener for the didFinishLaunching event without overwriting
// the one already defined by Phonegap.
+ (void)load
{
    Method original, swizzled;

    original = class_getInstanceMethod(self, @selector(init));
    swizzled = class_getInstanceMethod(self, @selector(swizzled_init));
    method_exchangeImplementations(original, swizzled);
}

- (AppDelegate *)swizzled_init
{
    [[NSNotificationCenter defaultCenter] addObserver:self selectorselector(launchHandler
                                                 name"UIApplicationDidFinishLaunchingNotification" object:nil];

    // This actually calls the original init method over in AppDelegate.
    return [self swizzled_init];
}

// This code will be called immediately after application:didFinishLaunchingWithOptions:.
- (void)launchHandlerNSNotification *)notification
{
    NSString* apiKey = @"xxxxx";
    // Do some initialisation and register the device using the apiKey
}

@end

apiKey 是特定于我的应用程序的，现在它在 AppDelegate+MyLib.m 中定义，如上面的代码所示。我的问题是，有没有办法让我的 Phonegap 应用程序在导入插件时自定义它？是否可以在我的应用程序的 config.xml 中定义(或在任何其他地方，如果有影响的话)并以某种方式作为参数传递给插件的 AppDelegate？

首先，您不需要使用 swizzling，只需阅读如何从 CDVPlugin 子类获取 UIApplicationDidFinishLaunchingNotification

Customizing iOS's application:didFinishLaunchingWithOptions: method in a Cordova/Ionic project

现在您可以在 config.xml 中使用偏好标签

 <preference name="apiKey" value="yourApiKeyHere" />

然后，您会在代码中(在 CDVPlugin 子类上)获得“apiKey”:

NSString* apiKey = [self.commandDelegate.settings objectForKey:[@"apiKey" lowercaseString]];
