我有3个不同的xib。我可以回去查看图1和图2用下面的代码之间来回...iPhone UINavigation Controller问题？
本规范带来了第二种观点...
-(IBAction)startButtonClicked:(id)sender{
self.gamePlayViewController = [[GamePlayViewController alloc] initWithNibName:@"GamePlayViewController" bundle:nil];
[self.navigationController pushViewController:gamePlayViewController animated:YES];
[GamePlayViewController release];
}
本准则第二视图下执行而让我回到第一个视图...
- （IBAction为）backButtonClicked {
[self.navigationController popViewControllerAnimated:YES];
}
现在，当我尝试执行此代码（在第二个视图中）以进入第三个视图时...我得到SIGABRT和应用程序崩溃......为什么它会为第一个视图启动第二个视图，但不是为了提出第三种观点的第二种观点？
- （IBAction为）新思维{
self.thirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
[self.navigationController pushViewController:thirdViewController animated:YES];
[thirdViewController release];
}
