UITabBarControllerで動作させる必要があるため、現在UISplitViewControllerで遊んでいます。数回試した後、私はついにそれを行うための便利な方法を見つけました。私が得る唯一の問題は、詳細とマスタービューがIBで構成され、適切にリンクされているにもかかわらず、手動でインスタンス化する必要があることです。
これが私のやり方です
MainWindow.xibでUITabBarCOntrollerを初期化し、タブバー項目を設定します。
私の最初のタブコントローラーはUISplitViewControllerを継承し、xibでセットアップされています。これがこのFirstViewControllerクラスの実装です
#import "FirstSplitViewController.h"
#import "MasterSplitViewController.h"
#import "DetailSplitViewController.h"
@implementation FirstSplitViewController
@synthesize detailSplitViewController,masterSplitViewController;
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
/*
masterSplitViewController = [[[MasterSplitViewController alloc] initWithNibName:@"MasterSplitViewController" bundle:nil] autorelease];
detailSplitViewController = [[[DetailSplitViewController alloc] initWithNibName:@"DetailSplitViewController" bundle:nil] autorelease];
*/
self.viewControllers = [NSArray arrayWithObjects:masterSplitViewController, detailSplitViewController , nil];
self.delegate = detailSplitViewController;
}
- (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];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
@end
これが私のMasterSplitviewの実装です
#import "MasterSplitViewController.h"
@implementation MasterSplitViewController
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
/*
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization.
}
return self;
}
*/
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
}
- (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];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
@end
と私のDetailSplitViewControllerの実装
#import "DetailSplitViewController.h"
@interface DetailSplitViewController ()
@property (nonatomic, retain) UIPopoverController *popoverController;
- (void)configureView;
@end
@implementation DetailSplitViewController
@synthesize toolbar, popoverController, detailItem, detailDescriptionLabel;
/*
When setting the detail item, update the view and dismiss the popover controller if it's showing.
*/
- (void)setDetailItem:(id)newDetailItem {
if (detailItem != newDetailItem) {
[detailItem release];
detailItem = [newDetailItem retain];
// Update the view.
[self configureView];
}
if (self.popoverController != nil) {
[self.popoverController dismissPopoverAnimated:YES];
}
}
- (void)configureView {
// Update the user interface for the detail item.
// detailDescriptionLabel.text = [detailItem description];
}
- (void)splitViewController: (UISplitViewController*)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem*)barButtonItem forPopoverController: (UIPopoverController*)pc
{
barButtonItem.title = @"Root List";
NSMutableArray *items = [[toolbar items] mutableCopy];
[items insertObject:barButtonItem atIndex:0];
[toolbar setItems:items animated:YES];
[items release];
self.popoverController = 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 {
NSMutableArray *items = [[toolbar items] mutableCopy];
[items removeObjectAtIndex:0];
[toolbar setItems:items animated:YES];
[items release];
self.popoverController = nil;
}
- (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];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
//[toolbar release];
[super dealloc];
}
@end
Everitingはxibに接続されており、FirstSplitViewControllerがxibからロードされるときに、マスターと詳細のsplitviewコントローラーが割り当てられない(IBでリンクされている)という問題が発生します。それらを手動で割り当てると、すべてが魅力のように機能します(FirstSplitViewController.mで以下のalloc init行のコメントを解除します)
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
/*
masterSplitViewController = [[[MasterSplitViewController alloc] initWithNibName:@"MasterSplitViewController" bundle:nil] autorelease];
detailSplitViewController = [[[DetailSplitViewController alloc] initWithNibName:@"DetailSplitViewController" bundle:nil] autorelease];
*/
self.viewControllers = [NSArray arrayWithObjects:masterSplitViewController, detailSplitViewController , nil];
self.delegate = detailSplitViewController;
}
だから私の質問は、xibがロードされているときにそれらのオブジェクトがロードされないのはなぜですか?これを手動で行うのは本当に初めてです。多分私は何かが欠けています。
回答やアドバイスをありがとう
