iphone - 从 tableviewcontroller 推送时的黑色背景

Question

我有一个选项卡 View Controller ，其中包含一个 TableView Controller 。当您按下表格行时，它会打开另一个 tableviewcontroller(如 detailtableviewcontroller)....我在右上角有一个导航按钮，如“添加”或“+”。我想在按下 + 按钮时加载一个 View Controller ，但每次按下它时， View Controller 只是一个黑色背景

AddSeasonViewController *stvc = [[AddSeasonViewController alloc] init];
//[self presentModalViewController:stvc animated:YES];
[self.navigationController pushViewController:stvc animated:YES];

[stvc release];

以上代码摘自detailTableViewController

感谢任何帮助，提前致谢!

看起来你没有正确初始化 viewController

AddSeasonViewController *viewController = [[AddSeasonViewController alloc] initWithNibName:@"AddSeasonViewController" bundle:nil];

-->if you have a UINavigationController assigned in the UItabBarController, you can use this

[self.navigationController pushViewController:viewController animated:YES];

-->I think in your case you are simply adding a viewController to the UITabBarController, then pushViewController will not work

[self presentModalViewController:viewController animated:YES];
  [stvc release];
