Phonegap Plugin - append lines to app delegate

问题

I'm developing a phonegap plugin. So far so good. Now I would like to append 1 or 2 methods to the AppDelegate.m through the config.xml so it will be populated for the developer automatically. Is it possible?

Thanks.

回答1:

take a look into the Push Plugin, they use an objective-c category for the appDelegate

If you just want to be notified when the app becomes active you don't need to change anything on the AppDelegate, just put this on your plugin:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onAppDidBecomeActive:) name:UIApplicationDidBecomeActiveNotification object:nil]; 

- (void)onAppDidBecomeActive:(NSNotification*)notification
{

     NSLog(@"%@",@"applicationDidBecomeActive");

}

If you do need to override some other method, like if iOS doesn't issue a notification for some app delegate method, you can do it with method swizzling. jcesarmobile mentioned this repo in his answer, but a file with an example is:
