Question

我开始在标签栏应用程序模板中开发应用程序..

这里我的第一页是登录页面，在loagin后进入主页，所有导航都会发生..

这里我不想只在登录页面中使用标签栏。如何做到这一点？

谢谢......

Answer 1

在第一个选项卡上，添加您是否登录所需的任何检查，如果没有，则显示带有登录字段的模态视图。

//some test here to determine state of self.registered
if(self.registered==FALSE){
            LoginViewController *login = [[LoginViewController alloc] initWithNibName: @"loginView" bundle: nil];
            login.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
            [self.navigationController presentModalViewController:login animated:YES];
            [login release];
        }

有了这个你可以隐藏和如何uitabbarcontroller -

- (void) hideTabBar:(UITabBarController *) tabbarcontroller {


    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        if([view isKindOfClass:[UITabBar class]])
        {
            [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
        } 
        else 
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
        }

    }

    [UIView commitAnimations];





}

- (void) showTabBar:(UITabBarController *) tabbarcontroller {

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        NSLog(@"%@", view);

        if([view isKindOfClass:[UITabBar class]])
        {
            [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)];

        } 
        else 
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)];
        }


    }

    [UIView commitAnimations]; 
}

你可以这样做：

在delegate.h中声明您的观点，

UIView *indicatorView; 
UIImageView *splashV;

现在在delegate.m

- (void)applicationDidFinishLaunching:(UIApplication *)application 
{
         indicatorView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
     splashV=[[UIImageView alloc]initWithFrame:CGRectMake(0, 20, 320, 460)];
     [splashV setImage:[UIImage imageNamed:@"Default.png"]];
     [indicatorView setBackgroundColor:[UIColor clearColor]];

        [indicatorView addSubview:splashV];
    [self.window addSubview:indicatorView];

}

＆安培; 成功登录

-(void)SuccessfulLoginDone
{
    [window addSubview:[tabBarController view]];

    [window makeKeyAndVisible];

}

希望能够做得更好。
