1 appdelegate.h
定义属性： window，navigationViewController
@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) UINavigationController *navigationViewController;
@end
2 appdelegate.m
对属性初始化，窗口初始化
@implementation AppDelegate
@synthesize window=_window;
@synthesize navigationViewController=_navigationViewController;
- (void)dealloc
{
[_window release];
[_navigationViewController release];
[super dealloc];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
RootViewController* rootViewController=[[[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil] autorelease];
self.navigationViewController=[[[UINavigationController alloc] initWithRootViewController:rootViewController] autorelease];
self.window.rootViewController = self.navigationViewController;
[self.window makeKeyAndVisible];
return YES;
}
3 RootViewController.h 初始化加载数据到tabveiwController
- (void)viewDidLoad
{
[super viewDidLoad];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
self.categary=[NSArray arrayWithObjects:@"11",@"22",@"33",@"44", nil];
self.title=@"sina wei bo";
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [self.categary count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// Configure the cell...
if (cell==nil) {
cell=[[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator;
cell.textLabel.text=[self.categary objectAtIndex:indexPath.row];
cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
点击一个CELL，跳转到下一窗口
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Navigation logic may go here. Create and push another view controller.
/*
<#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:@"<#Nib name#>" bundle:nil];
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
*/
SubViewController *subViewController=[[SubViewController alloc] initWithNibName:@"SubViewController" bundle:nil];
[self.navigationController pushViewController:subViewController animated:YES];
[SubViewController release];
}
