使用Kal calendar而不在AppDelegate中进行初始化(等等)

我用的是 Kal calendar . 对于下面显示的代码,我指的是假日示例。在这个例子中,Kal的分配和初始化是在 applicationDidFinishLaunching AppDelegate . 这个 UITableViewDelegate 协议(例如。 didSelectRowAtIndexPath )也位于 应用程序委派

应用程序委派

#import "HolidayAppDelegate.h"
#import "HolidaySqliteDataSource.h"
#import "HolidaysDetailViewController.h"
## Heading ###import "Kal.h"

@implementation HolidayAppDelegate

@synthesize window;

- (void)applicationDidFinishLaunching:(UIApplication *)application
{
  kal = [[KalViewController alloc] init];

  kal.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Today" style:UIBarButtonItemStyleBordered target:self action:@selector(showAndSelectToday)] autorelease];
  kal.delegate = self;
  dataSource = [[HolidaySqliteDataSource alloc] init];
  kal.dataSource = dataSource;

  // Setup the navigation stack and display it.
  navController = [[UINavigationController alloc] initWithRootViewController:kal];
  [window addSubview:navController.view];
  [window makeKeyAndVisible];
}

// Action handler for the navigation bar's right bar button item.
- (void)showAndSelectToday
{
  [kal showAndSelectDate:[NSDate date]];
}

#pragma mark UITableViewDelegate protocol conformance

// Display a details screen for the selected holiday/row.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
  Holiday *holiday = [dataSource holidayAtIndexPath:indexPath];
  HolidaysDetailViewController *vc = [[[HolidaysDetailViewController alloc] initWithHoliday:holiday] autorelease];
  [navController pushViewController:vc animated:YES];
}

#pragma mark -

- (void)dealloc
{
  [kal release];
  [dataSource release];
  [window release];
  [navController release];
  [super dealloc];
}

@end

我不想把这个放进 应用程序委派 ,因为可能存在与其他视图重叠的代码。它应该是一个单独的“组件”,我可以调用它并将其放在堆栈上。

RootViewController . 从那里我想把Kal视图推到堆栈上。目前我正在推动一个额外的 ViewController 在堆栈上。在 viewWillAppear

• 导航返回必须完成两次(一次用于Kal日历,一次用于我创建的视图)

现在我不知道该把代码放在哪里。所以问题是在哪里放置分配/初始化的方法以及 协议。

解决方案:

if (kal == nil) {
    kal = [[KalViewController alloc] init];
    kal.navigationItem.title = NSLocalizedString(@"Timetable",@"");
    kal.delegate = self;
    self.dataSource = [[[MyDataSource alloc] init] autorelease];
    kal.dataSource = dataSource;
}
[[self navigationController] pushViewController:kal animated:YES];
