Three20：使用presentModalViewController拋出setOriginalNavigatorURL無法識別的選擇器的TTLauncherView

Question

您好我是一個newbee到three20。 我收到“ SettingsViewController setOriginalNavigatorURL無法識別的選擇器已發送”異常。 如果我的應用程序中已有導航控制器，如何使用TTLauncherView？

我有一個UINavigationController內的UITableViewController。 我要在表格中選擇“設置”行時啟動啟動器。 以下是我所做的：

- (void)tableView:(UITableView *)tableView 
        didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    switch ([indexPath row]){
      case 0:
        [self launchSettings];
        break;
    // ....
}

-(void)launchSettings
{

    TTNavigator* navigator = [TTNavigator navigator];
    navigator.persistenceMode = TTNavigatorPersistenceModeAll;
    TTURLMap* map = navigator.URLMap;
    [map from:@"*" toViewController:[TTWebController class]];
    [map from:@"tt://launcher/" toViewController:
     [SettingsViewController class]];


    if (![navigator restoreViewControllers]) {
        [navigator openURLAction:
         [TTURLAction actionWithURLPath:@"tt://launcher"]];
    }   
    [self presentModalViewController:[navigator openURLAction:
                                  [TTURLAction actionWithURLPath:@"tt://launcher"]] animated:YES];
}

我有一個SettingsViewController：用的UIViewController的loadView，我創建了TTLauncherView並將其添加為子視圖SettingsViewController：

- (void)loadView {
    [super loadView];
    TTLauncherView* launcherView = [[TTLauncherView alloc]
                                    initWithFrame:self.view.bounds];
    launcherView.backgroundColor = [UIColor blackColor];
    launcherView.columnCount = 4;
    launcherView.pages = [NSArray arrayWithObjects:
                          [NSArray arrayWithObjects:
                           [self launcherItemWithTitle:@"Google"
                                 image:@"bundle://safari_logo.png"
                                 URL:@"http://google.com"],
                           [self launcherItemWithTitle:@"Apple"
                                 image:@"bundle://safari_logo.png"
                                 URL:@"http://apple.com"]
                           , nil]
                          , nil];

    [self.view addSubview:launcherView];
    [launcherView release];
}

- (TTLauncherItem *)launcherItemWithTitle:(NSString *)pTitle
                       image:(NSString *)image URL:(NSString *)url {
    TTLauncherItem *launcherItem = [[TTLauncherItem alloc]
                       initWithTitle:pTitle
                       image:image
                       URL:url canDelete:YES];
    return [launcherItem autorelease];
}

Answer 1

語法錯誤？

 switch ([indexPath row]){
  case 0:
    launchSettings;  -> [self launchSettings];
    break;

Answer 2

-ObjC -all_load在其他編譯器標志中丟失。 這些是使用three20所必需的。 參見http://three20.info/article/2010-10-06-Adding-Three20-To-Your-Project
