-(void)clickPress{
    secondeViewViewController *c = [[secondeViewViewController alloc]initWithNibName:@"secondeViewViewController" bundle:nil]; 

c.parent = self;

    [self presentModalViewController:c animated:YES];
}

 方法:self presentModalViewController:c animated:YES表示视图跳转.上面一行是指定要跳转到的视图.

利用父视图关闭自身

#import <UIKit/UIKit.h>
#import "ViewController.h"

@interface secondeViewViewController : UIViewController
@property(assign) ViewController *parent;
- (IBAction)finishBtnPress:(id)sender;
@end

- (IBAction)finishBtnPress:(id)sender {
    [self.parent dismissViewControllerAnimated:YES completion:nil];
}

AppDelegate.m中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; 
    self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
    
    UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:self.viewController];
    
    self.window.rootViewController = navController;
    [self.window makeKeyAndVisible];
    return YES;
}

ViewController.m 实现nav跳转

-(void)clickPress{
    secondeViewViewController *c = [[secondeViewViewController alloc]initWithNibName:@"secondeViewViewController" bundle:nil];
     
    [self.navigationController pushViewController:c animated:YES];

}
