UISplitViewController用法
公司要做ipad客户端了，所以研究了ipad下才有的UISplitViewController
UISplitViewController 只能作为window的rootViewController，所以我们可以先自定义个RootViewController继承UISplitViewController
#import <UIKit/UIKit.h>
@interface RootViewController : UISplitViewController
@end
- (void)viewDidLoad
{
[superviewDidLoad];
MenuTableViewController *MenuTVC = [[MenuTableViewControlleralloc] init];
DetailViewController *detailVC = [[DetailViewControlleralloc] init];
self.viewControllers = [NSArrayarrayWithObjects:MenuTVC,detailVC, nil];
self.delegate = detailVC;
}
然后分别定义SplitViewController的列表页MenuTableViewController
#import <UIKit/UIKit.h>
@interface MenuTableViewController :UITableViewController{
NSArray *_arr;
}
@property(nonatomic,retain)NSArray *arr;
@end
#import "MenuTableViewController.h"
#import "DetailViewController.h"
@implementation MenuTableViewController
@synthesize arr=_arr;
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
self.arr=[NSArrayarrayWithObjects:@"1",@"2",@"3",@"4",@"5",@"6",@"7", nil];
}
returnself;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[superdidReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[superviewDidLoad];
}
- (void)viewDidUnload
{
[superviewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
returnYES;
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
returnself.arr.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCellalloc] initWithStyle:UITableViewCellStyleDefaultreuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
cell.textLabel.text=[ self.arrobjectAtIndex:indexPath.row];
return cell;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
DetailViewController *detailVC=[self.splitViewController.viewControllersobjectAtIndex:1];
detailVC.lable.text=[self.arr objectAtIndex:indexPath.row];
[detailVC.popdismissPopoverAnimated:YES];
[detailVC release];
[MenuTVC release];
}
@end
正文页DetailViewController
#import <UIKit/UIKit.h>
#import <CommonCrypto/CommonDigest.h>
@interface DetailViewController : UIViewController<UISplitViewControllerDelegate>{
UILabel *_lable;
UIToolbar *_toolBar;
UIPopoverController *_pop;
}
@property(nonatomic,retain)UILabel *lable;
@property(nonatomic,retain)UIToolbar *toolBar;
@property(nonatomic,retain)UIPopoverController *pop;
@end
#import "DetailViewController.h"
@implementation DetailViewController
@synthesize lable=_lable,toolBar=_toolBar,pop=_pop;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
returnself;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[superdidReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[superviewDidLoad];
// Do any additional setup after loading the view from its nib.
self.lable=[[[UILabelalloc] initWithFrame:CGRectMake(100, 200, 50, 50)] autorelease];
self.view.backgroundColor=[UIColorredColor];
[self.viewaddSubview:self.lable];
}
- (void)viewDidUnload
{
[superviewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
returnYES;
}
- (void)splitViewController: (UISplitViewController*)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem*)barButtonItem forPopoverController: (UIPopoverController*)pc{
self.toolBar=[[[UIToolbaralloc] initWithFrame:CGRectMake(0, 0, 768, 50)] autorelease];
barButtonItem.title=@"菜单";
UIViewController *two=[svc.viewControllersobjectAtIndex:1];
[two.view addSubview:self.toolBar];
[self.toolBarsetItems:[NSArrayarrayWithObject:barButtonItem]
animated:YES];
self.pop=pc;
}
// Called when the view is shown again in the split view, invalidating the button and popover controller
- (void)splitViewController: (UISplitViewController*)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem{
if (self.toolBar!=nil) {
[self.toolBarremoveFromSuperview];
}
