Navigation 使用心得

構想: two view
1. main view: include current time and battery status
2. table view: record current time and battery level, using NSTimer

main view按下info button會顯示table view

----------------------------------------------------------------------------------------
xcode:
new project -> view-based application (name: PowerBank)

//PowerBankAppDelegate.h

#import <UIKit/UIKit.h>

@class PowerBankViewController;

@interface PowerBankAppDelegate : NSObject <UIApplicationDelegate> {

     UIWindow *window;

UINavigationController *navigationController;

  PowerBankViewController *viewController;

}

@property (nonatomic, retain) IBOutlet UIWindow *window;

@property (nonatomic, retain) IBOutlet PowerBankViewController *viewController;

@end

//  PowerBankAppDelegate.m

#import "PowerBankAppDelegate.h"

#import "PowerBankViewController.h"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

navigationController = [[UINavigationController alloc] init];

PowerBankViewController *_powerBankViewController = [[PowerBankViewController alloc] init];

_powerBankViewController.title = @"Battery State";

[navigationController pushViewController:_powerBankViewController animated:NO];

[_powerBankViewController release];

    [self.window addSubview:navigationController.view];

    [self.window makeKeyAndVisible];

    return YES;

}

 建立IBAction in main view , 目的為秀table view

-(IBAction)showDataTble:(id)sender

{

DetailData *_showDetailData = [[DetailData alloc] init];

_showDetailData.receiveArrayBatLevel = arrayBatLevel;

_showDetailData.receiveArrayCurTime = arrayCurTime;

[self.navigationController pushViewController:_showDetailData animated:YES];

[_showDetailData release];

}
