iphone - 推送到视图控制器时崩溃 - 目标c

Question

当我尝试推送到视图控制器时，我的应用程序崩溃了。只有当我们尝试导航到另一个页面（push 和 presentModal）时才会发生这种情况。我还检查了IBOutlets视图控制器中应该推送的连接和其他连接。但是找不到线索。这是我进行推送的代码：

PhoneBookView *phoneBook = [[PhoneBookView alloc] initWithNibName:@"PhoneBook" bundle:[NSBundle mainBundle]];

[self.navigationController presentModalViewController:phoneBook animated:YES];

Answer 1

为您提供信息'presentModalViewController:animated:' is deprecated: first deprecated in iOS 6.0

尝试这个：

PhoneBookView *phoneBook = [[PhoneBookView alloc] initWithNibName:@"PhoneBookView" bundle:[NSBundle mainBundle]];
[self.navigationController presentViewController:phoneBook animated:YES completion:nil];

Answer 2

PhoneBookView *phoneBook = [[PhoneBookView alloc] initWithNibName:@"PhoneBook" bundle:[NSBundle mainBundle]];

[self.navigationController presentModalViewController:phoneBook animated:YES];

使用代码呈现视图控制器

PhoneBookView *phoneBook = [[PhoneBookView alloc] initWithNibName:@"PhoneBook" bundle:[NSBundle mainBundle]];

[self presentModalViewController:phoneBook animated:YES];

并推送视图控制器

PhoneBookView *phoneBook = [[PhoneBookView alloc] initWithNibName:@"PhoneBook" bundle:[NSBundle mainBundle]];

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

Answer 3

[self.navigationController presentModalViewController:phoneBook animated:YES];此方法已弃用

相反，您可以使用

[self presentViewController:<#(UIViewController *)#> animated:<#(BOOL)#> completion:<#^(void)completion#>]

self presentViewController:phoneBook animated:YES completion:nil]

Answer 4

你可以试试这个，不需要指定捆绑，

PhoneBookView *phoneBook=[[PhoneBookView alloc] initWithNibName:@"PhoneBook" bundle:nil];

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

Answer 5

 PhoneBookView *phoneBook = [[PhoneBookView alloc] initWithNibName:@"PhoneBook" bundle:[NSBundle mainBundle]];
 UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:phoneBook];

[self.navigationController presentModalViewController:nav animated:YES];

如果要在呈现视图后进行推送操作，则需要添加 UINavigation 控制器作为该呈现视图的根视图控制器。

快乐的编码...

Answer 6

重置iOS模拟器，退出xcode并重新启动它，看看它是否对你有帮助，这似乎不是你的代码错误，而是xcode或模拟器之一。

Answer 7

尝试以下：

PhoneBookView *phoneBook = [[PhoneBookView alloc] initWithNibName:@"PhoneBookView" bundle:[NSBundle mainBundle]];
