Hi Jason,
Thanks again for your interest in my problem. But as i said, i did
my Delegate and it works good. I did something like this:
#include <QtCore>
@interface QIOSApplicationDelegate
@end
@interface QIOSApplicationDelegate(QtAppDelegate) // Put here the name
of your delegate...i used "QtAppDelegate"
@end
@implementation QIOSApplicationDelegate (QtAppDelegate)
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSLog(@"It Works!! When the app did finish launch ");
return YES;
}
@end
Using this code, you dont have to set the delegate in main. It works
perfectly ONLY WHEN the APP is in FOREGROUND /ACTIVE or in BACKGROUND.
My problem is that i need to use this delegate to get LOCATION when
the app is KILLED/TERMINATED/SUSPENDED.
See this link http://mobileoop.com/getting-location-updates-for-ios-7-and-8-when-the-app-is-killedterminatedsuspended.
Here the author gives an example of how to do this using Objective C.
I did the same example using QT...the code compiles and run perfectly
ony when the app is FOREGROUND /ACTIVE or in BACKGROUND...but not
when the app is KILLED/TERMINATED/SUSPENDED.
Any idea?
Best R,
Manoel
