[objective-c][iPad]Popoverを表示する

今日は、引き続き、iPadネタで、Popoverを出力する方法について
//sqliteBrowserAppDelegate.h

#import <UIKit/UIKit.h> #import "MainNavigationController.h" #import "MainViewController.h" @interface sqliteBrowserAppDelegate : NSObject { UIWindow *window; } @property (nonatomic, retain) IBOutlet UIWindow *window; @end

//"sqliteBrowserAppDelegate.m

#import "sqliteBrowserAppDelegate.h" @implementation sqliteBrowserAppDelegate @synthesize window; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { MainViewController *mainviewcontroller = [[MainViewController alloc] initWithNibName:nil bundle:nil]; MainNavigationController *mainnavigationcontroller = [[MainNavigationController alloc] initWithRootViewController:mainviewcontroller ]; [window addSubview:mainnavigationcontroller.view]; [window makeKeyAndVisible]; return YES; } - (void)applicationWillResignActive:(UIApplication *)application { } - (void)applicationDidBecomeActive:(UIApplication *)application { } - (void)applicationWillTerminate:(UIApplication *)application { } #pragma mark - #pragma mark Memory management - (void)applicationDidReceiveMemoryWarning:(UIApplication *)application { } - (void)dealloc { [window release]; [super dealloc]; } @end

//MainNavigationController.h

#import <UIKit/UIKit.h> #import "MainViewController.h" @interface MainNavigationController : UINavigationController { } @end

//MainNavigationController.m

#import "MainNavigationController.h" @implementation MainNavigationController - (id)initWithRootViewController:(UIViewController *)rootViewController{ if ((self = [super initWithRootViewController:rootViewController])) { } return self; } - (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end

//MainViewController.h

#import <UIKit/UIKit.h> #import "MainPopoverController.h" @interface MainViewController : UIViewController { } -(void)openPopover:(id)sender; @end

//MainViewController.m

#import "MainViewController.h" @implementation MainViewController -(void)openPopover:(id)sender{ MainPopoverController *mainpopovercontroller = [[MainPopoverController alloc] initWithContentViewController:[[UIViewController alloc] initWithNibName:nil bundle:nil] ]; [mainpopovercontroller presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; } - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { UIBarButtonItem *menubutton = [[UIBarButtonItem alloc] initWithTitle:@"Menu" style:UIBarButtonItemStyleBordered target:self action:@selector(openPopover:)]; menubutton.width = (CGFloat)150; self.navigationItem.leftBarButtonItem = menubutton; } return self; } - (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end

//MainPopoverController.h

#import <UIKit/UIKit.h> @interface MainPopoverController : UIPopoverController { } @end

//MainPopoverController.m

#import "MainPopoverController.h" @implementation MainPopoverController - (void)dealloc { [super dealloc]; } @end

実行結果はこちら↓

この機能っておそらくiPadだけの機能なんじゃーないのかなー。

Popoverが今は黒いけど、どんどんカスタマイズしていきたいなと。
