按钮单击工作时无法导航到iphone中的其他页面

Question

UIViewController *loginPage = [[[LoginPageViewController alloc] initWithNibName:@"LoginPageViewController" bundle:nil]autorelease];
[[self navigationController] pushViewController:loginPage animated:YES];

有了这部分代码，我想导航到另一个页面。我的按钮单击工作正常，并在级别显示文本。

有一个名为landingpageviewcontroller的类是另一个类LoginPageViewController。我想在landingpageviewcontroller的按钮点击操作上推送LoginPageViewController。你会发布一个示例代码吗？

Answer 1

[self presentViewController:loginPage animated:YES completion:nil];

换来的

[[self navigationController] pushViewController:loginPage animated:YES];

将工作。

Answer 2

尝试如下：

TabsViewController *hello=[[TabsViewController alloc]initWithNibName:@"TabsViewController" bundle:[NSBundle mainBundle]];
 [self.navigationController pushViewController:hello animated:YES];
    [hello release];

根据你改变它并检查。

Answer 3

LoginPageViewController  *loginPage = [[[LoginPageViewController alloc] initWithNibName@"LoginPageViewController" bundle:nil]autorelease];
[self navigationController pushViewController:loginPage animated:YES];
[loginPage release];

Answer 4

请尝试以下代码

LandingPageViewController.m类

 #import"LoginPageViewController.h" //must import .h file

@implementation LandingPageViewController

-(IBAction)onLoginClick:(id)sender
{

    LoginPageViewController *loginController = [[[LoginPageViewController alloc] initWithNibName:@"LoginPageViewController" bundle:nil]autorelease];
    [self.navigationController pushViewController:loginController animated:YES];


}

@end

Answer 5

试试这个

  LoginPageViewController *loginPage = [[[LoginPageViewController alloc] initWithNibName:@"LoginPageViewController" bundle:[NSBundle mainBundle]]autorelease];
  [[self navigationController] pushViewController:loginPage animated:YES];

Answer 6

LoginPageViewController  *move = [[LoginPageViewController alloc] initWithNibName@"LoginPageViewController" bundle:nil];
[self.navigationController pushViewController:move animated:YES];
[move release];

Answer 7

试试这个对你很有帮助。

 [self.navigationController popToViewController:[[self.navigationController viewControllers] objectAtIndex:0] animated:YES];

你可以尝试这个。查看控制器存储到堆栈。你可以直接给你的viewcontroller值。

就像第一个ViewController一样，然后放置0.如果第二个ViewController去，那么放置1.如果第三个ViewController去，那么放置2。
