应用程序将在iOS 4.0中终止

当我点击Home按钮时,我看到applicationWillResignActive和applicationidentinterbackground委托方法被调用。

 - (void)applicationWillResignActive:(UIApplication *)application
{
  NSLog(@"Application Did Resign Active");
}

- (void)applicationDidEnterBackground:(UIApplication *)application
{
  NSLog(@"Application Did Enter Background");
}

当我双击Home按钮并再次启动应用程序时,我发现applicationWillEnterForeground和applicationdidebecomeactive委托方法正在被调用。

 - (void)applicationWillEnterForeground:(UIApplication *)application
{
  NSLog(@"Application Will Enter Foreground");
}



- (void)applicationDidBecomeActive:(UIApplication *)application
{
  NSLog(@"Application Did Become Active");
}

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

}

有什么想法吗???
