a question about the sendEvent method of UIApplication

Question

I override the - (void)sendEvent:(UIEvent *)event method of UIApplication to handle some touch event.

.h

@interface myUIApplication : UIApplication {

}

.m

@implementation myUIApplication

- (void)sendEvent:(UIEvent *)event {
    NSLog(@"a event catched");
    [super sendEvent:event];
}

@end

and I edit my File's Owner's class to myUIApplication in MainWindow.xib. But when I touch the screen There is no output like @"a event catched"

Is there some mistake I have?

Thanks!

You will have to pass @"myUIApplication" to UIApplicationMain function. So it should be,

int retVal = UIApplicationMain(argc, argv, @"myUIApplication", nil);
