Question

I’m trying to understand why my application is not leaving main ( launching).
I think this line is the cause.

int retVal = UIApplicationMain(argc, argv, nil , nil);

The source code:

#import <UIKit/UIKit.h>

int main(int argc, char *argv[])
{
     printf("I'm in main");

    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    printf("\nafter the autiorealeas pool");

    int retVal = UIApplicationMain(argc, argv, nil , nil);

    printf("\nbefore the [pool relase] call");

    [pool release];
    printf("Leaving main");
    return retVal;
}

That’s right – it won’t return!
according to the Apple docs

Return Value

Even though an integer return type is specified, this function never returns. When users exits an iPhone application by pressing the Home button, the application moves to the background.
