    <p>In my three 20 project i am calling and sending some parameters to a method of my view controller using map object. I am passing the image name through parameter to my view controller. I have bound a xib file with my view controller . my xib contains a toolbar at the top and uiimage view. My problem is that when i pass parameter to my custom method and load my xib file in the next line then my view controller's view is not displayed on the screen. I am receiving the parameter in my custom method but unable to load xib on the screen. I am using the following custom method</p> <pre><code>-(void)loadImageWithName:(NSString *)img { PhotoView *vw = [[PhotoView alloc] initWithNibName:@"PhotoView" bundle:nil]; UIImage *tempImage = [UIImage imageNamed:img]; [vw.drawImage setImage:tempImage]; [self presentModalViewController:vw animated:YES]; } </code></pre> <p>When i do this i can see my xib loaded on the window.</p> <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [[TTURLRequestQueue mainQueue] setMaxContentLength:0]; TTNavigator *navigator = [TTNavigator navigator]; navigator.window = _window; TTURLMap *map = navigator.URLMap; [map from:@"tt://appPhotos" toSharedViewController:[PhotoViewController class]]; [map from:@"tt://photo" toSharedViewController:[PhotoView class]]; [navigator openURLAction:[TTURLAction actionWithURLPath:@"tt://photo"]]; [_window makeKeyAndVisible]; return YES; } </code></pre> <p>But when i do this my xib does not load and i see only a white screen</p> <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [[TTURLRequestQueue mainQueue] setMaxContentLength:0]; TTNavigator *navigator = [TTNavigator navigator]; navigator.window = _window; TTURLMap *map = navigator.URLMap; [map from:@"tt://appPhotos" toSharedViewController:[PhotoViewController class]]; [map from:@"tt://photo/(loadImageWithName:)" toSharedViewController:[PhotoView class]]; [navigator openURLAction:[TTURLAction actionWithURLPath:@"tt://photo/myphoto.png"]]; [_window makeKeyAndVisible]; return YES; } </code></pre> <p>This is the issue that i am facing right now.</p> <p>I solved the above issue by using</p> <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [[TTURLRequestQueue mainQueue] setMaxContentLength:0]; TTNavigator *navigator = [TTNavigator navigator]; navigator.window = _window; TTURLMap *map = navigator.URLMap; [map from:@"tt://appPhotos" toSharedViewController:[PhotoViewController class]]; [map from:@"tt://photo/detail?name=(initWithImage:)" toSharedViewController:[PhotoView class]]; [navigator openURLAction:[TTURLAction actionWithURLPath:[NSString stringWithFormat:@"tt://photo/detail?name=%@",@"level_me_up_small.png"]]]; [_window makeKeyAndVisible]; return YES; } </code></pre> <p>But still there are two probe.</p> <ol> <li>i am getting extra space between my toolbar at top and uiimageview. </li> </ol> <p>2.UIImageView image is not changed to instant_poetry_small.png.</p>

    3. COIs the NIB file at least loaded ? Could you log `vw` to see if it's a valid reference ? If none of what you tried work, you might have a problem with the file name, or the NIB file isn't included in the app bundle

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
