我编写了一个Phonegap插件,以便将我的Phonegap应用程序与本机SDK库集成。为了将一些设备注册信息传递给本机库,我使用了Objective-C类来在didFinishLaunchingWithOptions之后插入我自己的处理程序,这与Phonegap Push Plugin的方式非常相似。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 selector:@selector(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)launchHandler:(NSNotification *)notification
{
NSString* apiKey = @"xxxxx";
// Do some initialisation and register the device using the apiKey
}
@end
apiKey特定于我的应用程序,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?它可以在我的应用程序的config.xml中定义(或者在任何其他地方,如果这有所不同)并以某种方式作为参数传递给插件的AppDelegate?

首先,您不需要使用调配,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上使用首选项标签
<preference name="apiKey" value="yourApiKeyHere" />
然后,你的代码(在CDVPlugin子类上)得到“apiKey”:
NSString* apiKey = [self.commandDelegate.settings objectForKey:[@"apiKey" lowercaseString]];
