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。我还检查了视图控制器中应该被推送的IBOutlets和其他连接。但无法找到线索。这是我执行推送的代码：

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

试试这个：

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];

使用代码存在视图控制器

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

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

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

如果要在显示视图后执行推送操作，则需要将UINavigation控制器添加为该呈现视图的根视图控制器..

快乐的编码......

Answer 4

[self.navigationController presentModalViewController:phoneBook animated:YES];不推荐使用此方法

相反，您可以使用

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

self presentViewController:phoneBook animated:YES completion:nil]

Answer 5

你可以试试这个，不需要指定包，

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

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

Answer 6

重置iOS模拟器，退出xcode并重新启动它，让我们看看它是否对您有所帮助，这似乎不是您的代码错误，而是xcode或模拟器。

Answer 7

尝试使用以下内容：

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