PhoneGap / iOS LocalNotification App Crashes on tapping “View”

Question

I\'m having trouble here: I have the app set to not run in the background, and I\'m setting a dailyInterval localnotification using a localNotification plugin I found on git

Answer 1

I had a similar issue with local notifications. The solution that I chose is a bit different (though quite similar). I'm using a check for a local notification launch option (UIApplicationLaunchOptionsLocalNotificationKey).

Here is a short example:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

    if( localNotif ) 
    {
        // Do whatever you need to do with that local notitication
    }
    else
    {
        NSArray *keyArray = [launchOptions allKeys];
        if ([launchOptions objectForKey:[keyArray objectAtIndex:0]]!=nil) 
        {
            NSURL *url = [launchOptions objectForKey:[keyArray objectAtIndex:0]];
            self.invokeString = [url absoluteString];
        }
    }
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

OK, I found the problem, it's in the file AppDelegate.m and more precisely in the method : didFinishLaunchingWithOptions. The method assumes that the first option parameters is an url (but it's not when we launch the app via a Local Notification. The quick and dirty fix is to comment the code :

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //commented out because it makes the app crash at startup with local notification...
    /*NSArray *keyArray = [launchOptions allKeys];
    if ([launchOptions objectForKey:[keyArray objectAtIndex:0]]!=nil) 
    {
        NSURL *url = [launchOptions objectForKey:[keyArray objectAtIndex:0]];
        self.invokeString = [url absoluteString];
        NSLog(@"Mosa_fr_en-busi launchOptions = %@",url);
    }*/

    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

I've re-writen the localNotification plugin if anyone is interested - you can now add callbacks as well as sound. I like this fix for this problem as I have faced the same thing. I've also included it in the GIT project.

A little bit better solution is something like this:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    NSArray *keyArray = [launchOptions allKeys];
    if ([keyArray count] > 0) {
        id option = [launchOptions objectForKey:[keyArray objectAtIndex:0]];
        if ([option isKindOfClass:[NSURL class]]) {
            NSURL *url = (NSURL *)option;
            self.invokeString = [url absoluteString];
            NSLog(@"ContactInbox launchOptions = %@",url);
        }
    }

    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

If somebody knows what key PhoneGap expects to have for URL it's better to replace [keyArray objectAtIndex:0] part with actual key.
