ios - 如何启动没有 Storyboard 的另一个 View Controller ？

我没有使用情节提要或任何东西。我只是创建可可类并将它们单独链接起来。我可以加载默认的View Controller，即SplashViewController，但是我无法过去。

我有php，android编程和python的经验，但是我对Obj-C的工作方式以及iOS框架的工作方式一无所知:(

SplashViewController.m

-(void)initializeInterface
{
    //Initialize start button
    [self.startButton addTarget:self action:@selector(startActivity) forControlEvents:UIControlEventTouchDown];

    //Initialize fading backgrounds
    [self animateImages];


}
-(void)startActivity
{

    PhoneViewController *phoneView = [[PhoneViewController alloc] initWithNibName:@"PhoneViewController" bundle:nil];

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


}

SplashViewController.h

#import <UIKit/UIKit.h>
#import "PhoneViewController.m"

@class PhoneViewController;

@interface SplashViewController : UIViewController

@property (strong, nonatomic) PhoneViewController * phoneViewController;

@property UIImage *splashbg1;
@property UIImage *splashbg2;

@property (nonatomic, retain) IBOutlet UIImageView *splashbg;
@property (nonatomic, retain) IBOutlet UIButton *startButton;

-(void)initializeInterface;
-(void)animateImages;
-(void)startActivity;

@end

编辑

classAppDelegate.m

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];

    //Move from delegate view controller to root view controller
    self.window.rootViewController=[SplashViewController new];

    [self.window makeKeyAndVisible];
    return YES;
}

最佳答案

将初始视图控制器包装在导航控制器中。

否则，初始视图控制器的navigationController属性为nil，而pushViewController无效。

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController: splashViewController];
