UISplitView的简单示例

以前写了一篇文章：UISplitView的简单示例，这篇文章实现的功能类似，具体的实现请参考附件。

 

SplitViewTestAppDelegate.h

 

#import <UIKit/UIKit.h>

@class RootViewController;
@class DetailViewController;

@interface SplitViewTestAppDelegate : NSObject <UIApplicationDelegate> {    
    UIWindow *window;
    UISplitViewController *splitViewController;    
    RootViewController *rootViewController;
    DetailViewController *detailViewController;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UISplitViewController *splitViewController;
@property (nonatomic, retain) IBOutlet RootViewController *rootViewController;
@property (nonatomic, retain) IBOutlet DetailViewController *detailViewController;

@end

 

SplitViewTestAppDelegate.m

 

#import "SplitViewTestAppDelegate.h"
#import "RootViewController.h"
#import "DetailViewController.h"

@implementation SplitViewTestAppDelegate

@synthesize window, splitViewController, rootViewController, detailViewController;

#pragma mark -
#pragma mark Application lifecycle

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    [window addSubview:splitViewController.view];
    [window makeKeyAndVisible];
    
    return YES;
}

#pragma mark -
#pragma mark Memory management

- (void)dealloc {
    [splitViewController release];
    [window release];
    [super dealloc];
}

@end

 

RootViewController.h

 

#import <UIKit/UIKit.h>

@class DetailViewController;

@interface RootViewController : UITableViewController {
    DetailViewController *detailViewController;
    NSMutableArray *fruits;
}

@property (nonatomic, retain) IBOutlet DetailViewController *detailViewController;
@property (nonatomic, retain) NSMutableArray *fruits;

@end

 

RootViewController.m

 

#import "RootViewController.h"
#import "DetailViewController.h"

@implementation RootViewController

@synthesize detailViewController;
@synthesize fruits;

#pragma mark -
#pragma mark View lifecycle

- (void)viewDidLoad {
    [super viewDidLoad];
	self.title = @"List of Fruits";
    self.clearsSelectionOnViewWillAppear = NO;
    self.contentSizeForViewInPopover = CGSizeMake(320.0, 600.0);
	self.fruits = [[NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"fruits" ofType:@"plist"]] retain];
}

#pragma mark -
#pragma mark Table view data source

- (NSInteger)tableView:(UITableView *)aTableView numberOfRowsInSection:(NSInteger)section {
    return [fruits count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {    
    static NSString *CellIdentifier = @"CellIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        cell.accessoryType = UITableViewCellAccessoryNone;
    }

    cell.textLabel.text = [self.fruits objectAtIndex:indexPath.row];
    return cell;
}

#pragma mark -
#pragma mark Table view delegate

- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    detailViewController.detailItem = [self.fruits objectAtIndex:indexPath.row];
}

#pragma mark -
#pragma mark Memory management

- (void)dealloc {
	[self.fruits release];
    [detailViewController release];
    [super dealloc];
}

@end

 

DetailViewController.h

 

#import <UIKit/UIKit.h>

@interface DetailViewController : UIViewController <UIPopoverControllerDelegate, UISplitViewControllerDelegate> {
    
    UIPopoverController *popoverController;
    UINavigationBar *navigationBar;
    
    id detailItem;
    UILabel *detailDescriptionLabel;
	
	IBOutlet UIImageView *fruitImageView;
}

@property (nonatomic, retain) IBOutlet UINavigationBar *navigationBar;
@property (nonatomic, retain) id detailItem;
@property (nonatomic, retain) IBOutlet UILabel *detailDescriptionLabel;
@property (nonatomic, retain) IBOutlet UIImageView *fruitImageView;

@end

 

DetailViewController.m

 

#import "DetailViewController.h"
#import "RootViewController.h"

@interface DetailViewController ()
@property (nonatomic, retain) UIPopoverController *popoverController;
- (void)configureView;
@end

@implementation DetailViewController

@synthesize navigationBar, popoverController, detailItem, detailDescriptionLabel, fruitImageView;

#pragma mark -
#pragma mark Managing the detail item

- (void)setDetailItem:(id)newDetailItem {
    if (detailItem != newDetailItem) {
        [detailItem release];
        detailItem = [newDetailItem retain];
        
		navigationBar.topItem.title = detailItem;
		
		NSString *imageName = [NSString stringWithFormat:@"%@.png", detailItem];
		[self.fruitImageView setImage:[UIImage imageNamed:imageName]];

        [self configureView];
    }

    if (popoverController != nil) {
        [popoverController dismissPopoverAnimated:YES];
    }        
}

- (void)configureView {
    detailDescriptionLabel.text = [detailItem description];   
}

#pragma mark -
#pragma mark Split view support

- (void)splitViewController: (UISplitViewController*)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem*)barButtonItem forPopoverController: (UIPopoverController*)pc {    
    barButtonItem.title = @"Master List";
    [navigationBar.topItem setLeftBarButtonItem:barButtonItem animated:YES];
    self.popoverController = pc;
}

- (void)splitViewController: (UISplitViewController*)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem {
    [navigationBar.topItem setLeftBarButtonItem:nil animated:YES];
    self.popoverController = nil;
}

- (void)viewDidUnload {
    self.popoverController = nil;
}

#pragma mark -
#pragma mark Memory management

- (void)dealloc {
    [popoverController release];
    [navigationBar release];
    [detailItem release];
    [detailDescriptionLabel release];
    [super dealloc];
}

@end
