iphone - 如何在 iphone sdk 的单个视图控制器中从一个视图导航到另一个视图？

Question

有人可以告诉我：如何在 iphone sdk 的单个视图控制器中从一个视图导航到另一个视图？我有一个应用程序，我想在单个视图控制器中推送到下一个视图并弹出到上一个视图。如何实现此功能？提前致谢

Answer 1

您可以添加和删除您的第二视图。像这样导航

-(IBAction)navigate:(id)sender
{
  [self.view addSubView:secondView];
}

这个是第一个视图

-(IBAction)popToFirstView:(id)sender
{
  [secondView removeFromSuperView];
}

注意：- 如果要提供动画效果，可以使用动画来添加和删除视图。

Answer 2

如果您需要一个视图控制器，您可以尝试使用包含 2 个视图的 UIScrollView，以及一个从一个视图滚动到另一个视图的按钮......但如果我可以给出提示，最好使用 2 个视图控制器和一个导航视图控制器

您需要使用 UINavigation Controller 来获取推送和弹出。

这样做

在AppDelegate.h文件中

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;
//this will be your first screen
@property (strong, nonatomic) FavViewController *favViewController;

@end

在 A* ppDelegate.m * 文件中

#import "AppDelegate.h"
#import "FavViewController.h"


@implementation AppDelegate

@synthesize window = _window;
@synthesize favViewController;

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 

        //initialize view controller
        favViewController = [[FavViewController alloc] initWithNibName:@"FavViewController" bundle:nil];

       //add navigation controller
        UINavigationController *favouriteView = [[UINavigationController alloc] initWithRootViewController:favViewController];  


       //add controller to witndow
        self.window.rootViewController = favouriteView;   
        [self.window makeKeyAndVisible];    

        return YES;
    }

@end

现在来到UIViewController，您想在其中加载/推送到新控制器

加载/推送到新控制器使用此代码

//this will be next screen
DetailsViewController *detailsViewController = [[DetailsViewController alloc ]init];
[self.navigationController pushViewController:detailsViewController animated:YES];

返回或弹出控制器使用此

//now it will send back to parent screen
[self.navigationController popViewControllerAnimated:YES];

我已经找到了解决这个问题的方法，下面是解决方案：-

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
{
    IBOutlet UIButton *backbtn;
    IBOutlet UIButton *nxtBtn;
    IBOutlet UILabel *label;
}
-(IBAction)nxt:(id)sender;
-(IBAction)ba:(id)sender;

@end

#import "ViewController.h"

@interface ViewController ()
@end

int count=0;

@implementation ViewController

- (void)viewDidLoad
{
    label.text=[[NSUserDefaults standardUserDefaults] objectForKey:@"NavigtionNumber"];
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}
-(IBAction)nxt:(id)sender
{
    count++;
    label.text=[NSString stringWithFormat:@" navigation time %d",count];

    [[NSUserDefaults standardUserDefaults] setObject:label.text forKey:@"NavigtionNumber"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    ViewController *vc=[[ViewController alloc] init];

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

}

-(IBAction)ba:(id)sender
{
    count--;
    label.text=[NSString stringWithFormat:@" navigation time %d",count];

    [[NSUserDefaults standardUserDefaults] setObject:label.text forKey:@"NavigtionNumber"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    [self.navigationController popViewControllerAnimated:YES];
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

@end

希望这将在未来对其他人有所帮助。

谢谢。
