[iPad][Objective-C]splitViewを表示する

iPadの新機能であるspliteViewを表示させる方法について書きたいと思います。

//sqliteBrowserAppDelegate.h

#import <UIKit/UIKit.h> #import "MainSplitViewController.h" #import "LeftNavigationController.h" #import "LeftTableViewController.h" #import "RightNavigationController.h" #import "RightViewController.h" @interface sqliteBrowserAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; } @property (nonatomic, retain) IBOutlet UIWindow *window; @end

//sqliteBrowserAppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { LeftTableViewController *lefttableviewcontroller = [[LeftTableViewController alloc] initWithStyle:UITableViewStylePlain]; LeftNavigationController *leftnavigationcontroller = [[LeftNavigationController alloc] initWithRootViewController:lefttableviewcontroller ]; RightViewController *rightviewcontroller = [[RightViewController alloc] initWithNibName:nil bundle:nil]; RightNavigationController *rightnavigationcontroller = [[RightNavigationController alloc] initWithRootViewController:rightviewcontroller ]; MainSplitViewController *mainsplitviewcontroller = [[MainSplitViewController alloc] init]; mainsplitviewcontroller.viewControllers = [NSArray arrayWithObjects:leftnavigationcontroller,rightnavigationcontroller,nil]; [window addSubview:mainsplitviewcontroller.view]; [window makeKeyAndVisible]; return YES; }

//MainSplitViewController.h

#import <UIKit/UIKit.h> @interface MainSplitViewController : UISplitViewController { } @end

//MainSplitViewController.m

#import "MainSplitViewController.h" @implementation MainSplitViewController - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Overriden to allow any orientation. return YES; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end

//LeftNavigationController.h

#import <UIKit/UIKit.h> @interface LeftNavigationController : UINavigationController { } @end

//LeftNavigationController.m

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

//LeftTableViewController.h

#import <UIKit/UIKit.h> @interface LeftTableViewController : UITableViewController { } @end

//LeftTableViewController.m

#import "LeftTableViewController.h" @implementation LeftTableViewController #pragma mark - #pragma mark Initialization - (id)initWithStyle:(UITableViewStyle)style { if ((self = [super initWithStyle:style])) { UIBarButtonItem *addbutton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:nil action:nil ]; self.navigationItem.leftBarButtonItem = addbutton; } return self; } #pragma mark - #pragma mark View lifecycle - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } #pragma mark - #pragma mark Table view data source - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 3; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell... return cell; } #pragma mark - #pragma mark Table view delegate - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { } #pragma mark - #pragma mark Memory management - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { } - (void)dealloc { [super dealloc]; } @end

//RightNavigationController.h

#import <UIKit/UIKit.h> @interface RightNavigationController : UINavigationController { } @end

//RightNavigationController.m

#import "RightNavigationController.h" @implementation RightNavigationController - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end

//RightViewController.h

#import <UIKit/UIKit.h> @interface RightViewController : UIViewController { } @end

//RightViewController.m

#import "RightViewController.h" @implementation RightViewController - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { self.view = [[UIView alloc] initWithFrame:CGRectMake(320, 0, 704, 768)]; self.view.backgroundColor = [UIColor whiteColor]; } return self; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end

実行結果は、このような感じになります。

特に重要なのが、UISplitViewControllerのインスタンス変数を作る際に、initをコールするということ。

実際にスプリット元になるviewcontrollerに関しては、その後の、viewControllersプロパティーで設定するということさえ押さえておけば、難しいことはありません。

こうして一度、まとめておけば、次も楽に作成することができるぞと。

ちなみに、参考にした箇所は、iPad Programming GuideのCreating a Split View Interfaceというところ。
