didSelectRowAtIndexPath当选择无法转到其他页面时

Question

if(!_personViewController) 
    { 
     _personViewController=[[PersonViewController alloc]initWithNibName:@"PersonViewController" bundle:nil]; 
    } 

    _personViewController.user=_user; 
    [self.navigationController pushViewController:_personViewController animated:YES]; 
    [PersonViewController release]; 

这是我的代码。我只想当选择行可以跳转到personViewController页面，但它看起来很糟糕。

Answer 1

试试这个..

//_personViewController.user=_user; 

或

_personViewController.user=[_user retain]; 

Answer 2

只是检查它是否在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions写导航控制器，它是AppDelegate.m文件。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
    { 

     self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; 
     self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] autorelease]; 
     UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController:self.viewController]; 

     [self.window addSubview:[navControl view]]; 

     [self.window makeKeyAndVisible]; 
     return YES; 
    }
