Question

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

-(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];
}

When i do this i can see my xib loaded on the window.

- (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;
}

But when i do this my xib does not load and i see only a white screen

- (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;
}

This is the issue that i am facing right now.

I solved the above issue by using

- (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;
}

But still there are two probe.

1. i am getting extra space between my toolbar at top and uiimageview.

2.UIImageView image is not changed to instant_poetry_small.png.

Answer 1

not sure if it will help, but try this:

vw.drawImage = [[UIImageView alloc]initWithImage:tempImage];

instead of

[vw.drawImage setImage:tempImage];

the rest of the code looks OK for me
