iPhone之UISplitViewController

转自：http://blog.sina.com.cn/s/blog_4adf31ea0100qxoh.html

UISplitViewController类，只有在ipad中才可以使用。

ipad的屏幕比iphone大，所以在界面上，ipad比iphone多一个UISplitViewController，用来实现ipad在横屏时，分两栏显示所需要的界面，可以一边是目录一边是具体的内容。




首先创建一个Row1Detail和RootViewController，其中RootViewController继承UITableViewController。同事创建两个相应的xib文件。

AppDelegate 中的代码如下：

@interfacetestsplitviewAppDelegate : NSObject<UIApplicationDelegate> {
UIWindow
*window;

UISplitViewController
*splitView;
RootViewController
*root;
Row1Detail
*detail;

}

@property
(nonatomic,retain) IBOutlet
UIWindow *window;
@property (nonatomic,
retain) IBOutlet UISplitViewController*splitView;
@property
(nonatomic,retain)IBOutlet
RootViewController*root;
@property
(nonatomic,retain) IBOutlet
Row1Detail *detail;

@end

实现类：

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

// Override point for customization afterapp launch.
[self.windowaddSubview:splitView.view];
[self.windowmakeKeyAndVisible];

return YES;
}

修改MainWindow.xib文件：添加UISplitViewController容器





绑定的事件如下：




RootViewController的代码如下：

@interface RootViewController :UITableViewController {
Row1Detail
*detail;
}

@property
(nonatomic,retain)IBOutlet
Row1Detail*detail;

@end

实现代码：

#import"RootViewController.h"

@implementationRootViewController
@synthesize
detail;

#pragma mark -
#pragma mark View lifecycle

-(void)viewDidLoad {
[superviewDidLoad];

self.clearsSelectionOnViewWillAppear=
NO;

self.contentSizeForViewInPopover
= CGSizeMake(320.0,600.0);
}

#pragma mark -
#pragma mark Table view data source

-(NSInteger)numberOfSectionsInTableView:(UITableView*)aTableView {

return 1;
}

-(NSInteger)tableView:(UITableView *)aTableViewnumberOfRowsInSection:(NSInteger)section {

return 10;
}

-(UITableViewCell*)tableView:(UITableView*)tableViewcellForRowAtIndexPath:(NSIndexPath
*)indexPath {

static NSString *CellIdentifier =
@"CellIdentifier";

UITableViewCell *cell = [tableViewdequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefaultreuseIdentifier:CellIdentifier]autorelease];
cell.accessoryType
= UITableViewCellAccessoryNone;
}

cell.textLabel.text = [NSString
stringWithFormat:@"Row %d", indexPath.row];

return cell;
}

#pragma mark -
#pragma mark Table view delegate

-(void)tableView:(UITableView *)aTableViewdidSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
detail.detailItem = [NSString
stringWithFormat:@"Row %d", indexPath.row];
}

Row1Detail的代码

@interface Row1Detail :UIViewController<UISplitViewControllerDelegate>{
UILabel
*Text1;

id detailItem;
}

@property
(nonatomic,retain)IBOutlet
UILabel *Text1;

@property
(nonatomic,retain) id
detailItem;

-(IBAction) click;

@end

实现代码如下：

#import "Row1Detail.h"

@implementation
Row1Detail
@synthesize
Text1;
@synthesize detailItem;

-(IBAction) click
{
NSLog(@"%@",Text1.text);

UIAlertView
*alert=[[UIAlertView alloc] initWithTitle:@"标题"message:@"22"
delegate:selfcancelButtonTitle:@"关"otherButtonTitles:nil];
[alert
show];

[alert
release];

Text1.text=@"11111111111";
}

-(void)setDetailItem:(id)newDetailItem
{

if (detailItem != newDetailItem) {
[detailItemrelease];

detailItem =[newDetailItem
retain];
Text1.text
=[detailItem description];

}

}

// Implement viewDidLoad to do additional setup after loading theview, typically from a nib.
-(void)viewDidLoad
{
[superviewDidLoad];
}

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
// Overriden to allow anyorientation.
return YES;
}
