objective-c

- (void)applicationDidFinishLaunching:(UIApplication *)application{



// Override point for customization after application launch
[window makeKeyAndVisible];
[self printFloat:1.3f];
}

- (void)printFloat:(float)f { 
    NSLog(@"%f",f);
}

I passed the "1.3f" to printFloat, but it was the wrong value (in this case, -2.000000) after "f" received. And there is a warning that "AppDelegate may not respond to -printFloat:"

Where did I get it wrong? Thanks.
