ipad浮动窗口的实现.doc

UISplitViewController类，只有在ipad中才可以使用。同学，在扣丁学堂上课，你还用ipad吗？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：interface testsplitviewAppDelegate : NSObject 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 *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions / Override point for customization after app launch.self.window addSubview:splitView.view;self.window makeKeyAndVisible;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.himplementation RootViewControllersynthesize detail;#pragma mark -#pragma mark View lifecycle- (void)viewDidLoad super viewDidLoad;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 *)aTableView numberOfRowsInSection:(NSInteger)section return 10;- (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 = NSString stringWithFormat:Row %d, indexPath.row;return cell;#pragma mark -#pragma mark Table view delegate- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath detail.detailItem = NSString stringWithFormat:Row %d, indexPath.row;Row1Detail的代码interface Row1Detail : UIViewController 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.himplementation Row1Detailsynthesize Text1;synthesize detailItem;-(IBAction) clickNSLog(%,Text1.text);UIAlertView *alert=UIAlertView alloc initWithTitle:标题 message:22 delegate:self cancelButtonTitle:关 otherButtonTitles:nil;alert show;alert release;Text1.text=11111111111;- (void)setDetailItem:(id)newDetailItemif (detailItem != newDetailItem) detailItem release;detailItem = newDetailItem retain;Text1.text = detailItem description;/ Implement viewDidLoad to do additional setup after loading the view, typically from a nib.- (void)viewDidLoadsuper
