iPhone开发常用控件之表TableView 【二】，点击一行进行view跳转

前面的多视图总结已经有过这个实现，现在把他放在这里，主要是练习一下TabView的使用。


Navigation通常与TableView搭配使用，博文iPhone开发常用控件之表TableView【一】 编写了一个TableView的示例，那是一个单视图应用，现在搭配上Navigation将其修改为多视图应用。


1，将TableView示例工程复制一份名称修改为TableViewDemo-Nav，打开该工程进行修改。




2、首先，修改AppDelegate，添加UINavigationController的实例，AppDelegate.h修改后如下：

#import <UIKit/UIKit.h>

@class ViewController;

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) ViewController *viewController;
//添加navigationController
@property (strong, nonatomic) UINavigationController *navigationController;
@end

3,修改AppDelegate.m中的didFinishLaunchingWithOptions方法，如下：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
    //注释掉下面一行代码
    /*
    self.window.rootViewController = self.viewController;*/
    //添加如下代码
    self.navigationController = [[UINavigationController alloc]initWithRootViewController:self.viewController];
    [self.window addSubview:self.navigationController.view];
    
    [self.window makeKeyAndVisible];
    return YES;
}

4、新建视图控制器AppViewController（带xib）,如下：

5、ViewController.h修改后如下：

#import <UIKit/UIKit.h>
#import "AppViewController.h"
@interface ViewController : UIViewController

@property(nonatomic,retain)NSMutableArray *apps;
@property(nonatomic,retain)AppViewController *appViewController;
@end

6、ViewController.m中主要是实现了-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath方法，如下：

//实现didSelectRowAtIndexPath
-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    NSString *imageName = [NSString stringWithFormat:@"%d",[indexPath row]+1];
    NSString *appName = [apps objectAtIndex:[indexPath row]];
    //初始化appViewController
    appViewController = [[AppViewController alloc]initWithNibName:@"AppViewController" bundle:nil];
    //传递参数
    appViewController.appName = appName;
    appViewController.appIconName = imageName;
    //跳转到appViewController
    [self.navigationController pushViewController:appViewController animated:YES];
}

7、AppViewController.h如下：

#import <UIKit/UIKit.h>

@interface AppViewController : UIViewController

@property(strong,nonatomic)NSString *appName;
@property(strong,nonatomic)NSString *appIconName;

@property(strong,nonatomic)IBOutlet UILabel *appNameLabel;
@property(strong,nonatomic)IBOutlet UIImageView *appIconImgView;
@end 

8、注意：将输出口与AppViewController.xib中的UI控件相连。AppViewController.xib如下:

9、AppViewController.m如下：

#import "AppViewController.h"

@interface AppViewController ()

@end

@implementation AppViewController
@synthesize appName;
@synthesize appIconName;
@synthesize appNameLabel;
@synthesize appIconImgView;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = @"AppViewController";
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    
    self.appNameLabel.text = appName;
    self.appIconImgView.image = [UIImage imageNamed:appIconName];
    
    NSLog(@"appName=%@,appIconName=%@",appName,appIconName);
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
    appName = nil;
    appIconName = nil;
    appNameLabel = nil;
    appIconImgView = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

@end

10、运行效果如下：
