Cordova plugin with framework with Appdelegate - ios

Question

I have created a framework with a native sdk that the company I work has for push notifications. I have an Appdelegate inside this framework because there are some files that use it. I have added this framework as a plug in for a Cordova test application but as I see I can use only one of the two AppDelegates that exist now(one in framework and one in cordova app). I am trying to use only the framework's AppDelegate but to do this I must somehow use CDVAppDelegate. The problem is that the app in initialization doesn't run the correct didFinishLaunchingWithOptions function and I can't see the default first page of the cordova app. I have this files inside the plug in:
AppDelegateExtension.m
#import "xxxSDK/AppDelegate.h"
#import "xxxSDK/xxx.h"
#import "MainViewController.h"
#import "MyPlugin.h"
#implementation AppDelegate (MyPlugin)
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
#if (DEBUG == 1)
[xxx launchWithAppUUID:#"1256fbeb638b4426a98e4bacbc5f56f5" launchOptions:launchOptions];
#else
[xxx launchWithAppUUID:#"1256fbeb638b4426a98e4bacbc5f56f5" launchOptions:launchOptions];
#endif
[[xxx sharedService].pushManager registerForRemoteNotifications];
[[xxx sharedService].pushManager resetBadge];
MyPlugin.myPlugin.viewController = [[MainViewController alloc] init];
[MyPlugin.myPlugin application:application didFinishLaunchingWithOptions:launchOptions];
return YES;
}
MyPlugin.h
#import <Cordova/CDVAppDelegate.h>
#interface MyPlugin : CDVAppDelegate
// Public static method
+ (CDVAppDelegate*) myPlugin;
#end
MyPlugin.m:
#import <Foundation/Foundation.h>
#import "MyPlugin.h"
#import "MainViewController.h"
#implementation MyPlugin
// Private static reference
static CDVAppDelegate* myPlugin;
// Public static method
+ (CDVAppDelegate*) myPlugin {
return myPlugin;
}
#end
Inside the framework the AppDelegate.h is this:
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#interface AppDelegate : UIResponder <UIApplicationDelegate>
#end
I have tried declare MyPlugin as a CDVPlugin too but the problem didnt get solved. Any thoughts?

Answer 1

Because AppDelegateExtension.m is a category of the AppDelegate class it extends the original class rather than implementing a subclass, so any methods you implement in your category which already exist in the main class (i.e. AppDelegate.m auto-generated by Cordova) will be replaced.
So in this case your didFinishLaunchingWithOptions in AppDelegateExtension.m is replacing didFinishLaunchingWithOptions in AppDelegate.m.
TL;DR: You need to swizzle the method to avoid destroying the original method:
#implementation AppDelegate (MyPlugin)
+ (void)load {
Method original = class_getInstanceMethod(self, #selector(application:didFinishLaunchingWithOptions:));
Method swizzled = class_getInstanceMethod(self, #selector(application:swizzledDidFinishLaunchingWithOptions:));
method_exchangeImplementations(original, swizzled);
}
- (BOOL)application:(UIApplication*)application swizzledDidFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
{
#if (DEBUG == 1)
[xxx launchWithAppUUID:#"1256fbeb638b4426a98e4bacbc5f56f5" launchOptions:launchOptions];
#else
[xxx launchWithAppUUID:#"1256fbeb638b4426a98e4bacbc5f56f5" launchOptions:launchOptions];
#endif
[[xxx sharedService].pushManager registerForRemoteNotifications];
[[xxx sharedService].pushManager resetBadge];
MyPlugin.myPlugin.viewController = [[MainViewController alloc] init];
[MyPlugin.myPlugin application:application didFinishLaunchingWithOptions:launchOptions];
return YES;
}
You can see an example of this in cordova-plugin-firebasex.

Ok, i did this:
#implementation AppDelegate (MyPlugin)
+ (void)load {
Method original = class_getInstanceMethod(self, #selector(application:didFinishLaunchingWithOptions:));
Method swizzled = class_getInstanceMethod(self, #selector(application:swizzledDidFinishLaunchingWithOptions:));
method_exchangeImplementations(original, swizzled);
}
- (BOOL)application:(UIApplication*)application swizzledDidFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
#if (DEBUG == 1)
[Warply launchWithAppUUID:#"1256fbeb638b4426a98e4bacbc5f56f5" launchOptions:launchOptions];
#else
[Warply launchWithAppUUID:#"1256fbeb638b4426a98e4bacbc5f56f5" launchOptions:launchOptions];
#endif
[[Warply sharedService].pushManager registerForRemoteNotifications];
[[Warply sharedService].pushManager resetBadge];
CDVAppDelegate *appDelegate = [[CDVAppDelegate alloc]init];
[appDelegate application:application didFinishLaunchingWithOptions:launchOptions];
return YES;
}
CDVAppdelegate's didFinishLaunchingWithOptions is running but I can not see in my device index.html view. My sdk runs properly but the cordova app is not running at all.
I assume that the thing is that AppDelegate : UIResponder can not support what I want to do and I am starting to believe that what I want can not be implemented.
